The SOLUTION for starting Termux-x11 from Termux by

Hossam001-bot

Works way much better . ! ! !
This solution removed issues with starting Termux-x11 .

.

Termux-11 Will start by typing in Termux :

termux-x11 > /dev/null &
pulseaudio --start --load="module-native-protocol-tcp auth-ip-acl=127.0.0.1 auth-anonymous=1" --exit-idle-time=-1

AUTOMATE START OF TERMUX-X11

OS Jammy on Arm64 Galaxy S20 DEX
Termux-x11 Build#164

Inspired by post

termux/termux-x11#138 (comment)

I tried to automate of starting Termux-x11 with Bash script and it worked .

Again , you have to be in Termux and not logged in Ubuntu .

If you are in Termux , you will see Termux sign

If you dont have Nano installed , install it :

apt install nano -y

In Termux type :

nano xgo

Nano will create file xgo

In xgo file paste next lines :

#!/bin/bash 

echo "" 
echo "1. [ SET RUNTIME DIR ]" 
export XDG_RUNTIME_DIR=${TMPDIR} 
echo "DONE" 

sleep 1 

echo "" 
echo "2. [ SET PULSE AUDIO ]" 
pulseaudio --start --load="module-native-protocol-tcp auth-ip-acl=127.0.0.1 auth-anonymous=1" --exit-idle-time=-1 
echo "DONE" 

sleep 1 
echo "" 
echo "3. [ START termux-x11 ]" 
termux-x11 > /dev/null & 
echo "DONE" 
echo "" 

sleep 6 

echo "" 
echo "4. [ DISTRO LOGIN && START X-11 ]"
echo "" 
proot-distro login udroid-jammy-raw --shared-tmp -- runuser -l v8 -c 'DISPLAY=:0 xfce4-session'
echo "" 
echo "DONE" 
echo "" 

exit 0

CTRL + o [ save ]
ENTER [ confirm name ]
CTRL + x [ Exit nano ]

You are now in Termux again and type

chmod +x xgo

mkdir bin

PATH="$PATH:$HOME/bin"

cp xgo bin

In order to make your PATH variable permanent have to edit config .

In Termux type :

nano ~/.profile

on the end of file add :

export PATH="$PATH:$HOME/bin"

Save and exit Nano .

For starting Termux-x11 you dont have to type all the commands over and over but simple type name of your script :

Type in Termux :

xgo

And you have your Termux-x11 started !

NOTE :

in line [ in xgo bash script ]

proot-distro login udroid-jammy-raw --shared-tmp -- runuser -l v8 -c 'DISPLAY=:0 xfce4-session

I am logged as v8 , if your login name is different replace v8 with your login name !

IF YOUR STARTUP OF TERMUX-X11 FAILS

Simply go to notification pane , roll down pane of Termux-x11 and click Exit .
Dont just close Termux-x11 window , it wont kill Termux-x11 session ,
Termux-x11 needs to be closed from notification pane in order to
end Termux-x11 session !

Get back to Termux and type :

xgo

And Termux-x11 is started !

EXITING FROM TERMUX-X11 SESSION

You will not end session of Termux-x11 by only closing its window ,
Termux-x11 session will remain active in memory and if you try again to start Termux-x11 ,
you will face black screen .
TERMUX-X11 MUST BE EXITED FROM NOTIFICATION PANE BY CLICKING ON EXIT !

On phone for exit from termux-x11 pull down notification pane and expand termux-x11
notification where you will see exit option.

.

On Samsung DEX notification pane for exit.

.

SNAP WILL NOT WORK WITH PROOT AND NEEDS TO BE REMOVED .

snapd is not working, and firefox needs snapd in Ubuntu 22.04,
so purge snapd and disable it .

At this point you dont have Web browser and can not see this guide in Jammy because copy / paste
does not work beetween Android and Jammy .

You can install in Jammy any Browser via apt or make pdf of this guide which then open from Jammy .

sudo apt install evince

But there is solution to this w3m , I think that it is already in system but if you need to install it :

sudo apt install w3m

w3m is terminal browser and will open web page inside terminal , it does not look perfect but you can read this guide from terminal .

Type in terminal :

w3m -v https://github.com/RandomCoderOrg/ubuntu-on-android/discussions/152

and it will open this page in terminal .

You can surf with w3m , also google things if started with :

w3m -v https://google.com/

Hit the q for exit from w3m .

Open xfce terminal on your Ubuntu .

sudo apt remove --purge --assume-yes snapd gnome-software-plugin-snap

rm -rf ~/snap/

sudo rm -rf /var/cache/snapd/

.

To prevent repository packages from triggering the installation of snap .

sudo nano /etc/apt/preferences.d/nosnap.pref

When the file opens, paste lines below to tell refuse snapd from any repository .
This file forbids snapd from being installed by APT.

Package: snapd
Pin: release a=*
Pin-Priority: -10

Save and exit nano .

.

Install the PPA and latest Firefox .

sudo apt-get install software-properties-common

sudo add-apt-repository ppa:mozillateam/ppa

.

Set the higher priority than snap for firefox .

sudo apt update

sudo nano /etc/apt/preferences.d/mozillateamppa

Paste this into file, save and exit .

Package: firefox*

Pin: release o=LP-PPA-mozillateam

Pin-Priority: 501

After saving

sudo apt update

sudo apt install firefox -y

.

Or install Chromium

curl -L -o chromium-install.sh https://raw.githubusercontent.com/RandomCoderOrg/udroid-app-ports/main/chromium/install.sh

sudo bash chromium-install.sh

Proot Tools [ Needed to be root@localhost , not logged into Ubuntu Jammy ]

Exit to Termux and from Termux type :

proot-distro login udroid-jammy-raw --shared-tmp

Now you are in root@localhost and type following :

git clone https://github.com/RandomCoderOrg/udroid-extra-tool-proot
cd udroid-extra-tool-proot
bash install.sh
cd
exit

FONTS ARE TO LARGE ON SOME APPLICATIONS

Adjust DPI scalling

.

Open Settings Manager in Ubuntu .

.

Click on Appearance .

.

On the window Appearance click tab Fonts .

Here you have Custom DPI settings .
For me 86% worked perfectly !

Disable anti-aliasing on fonts will speed up rendering fonts .

In Jammy disable Screensaver .

On Session and Startup disable

Power Manager and Screensaver

Install the software

sudo apt install libreoffice

sudo apt install gimp

sudo apt install inkscape

sudo apt install neofetch

sudo apt install htop

sudo apt install onboard

sudo apt install emacs

sudo apt install vlc

sudo apt -y install gnome-calculator

sudo apt install gpick

VS CODE #152 (comment)
Runs on any Android Web browser via Termux [ which is faster than X-11 ] , or any Web browser on Jammy .

With all apps above installed my distro is 1,81 GB .

UDROID Ubuntu 22.04 Jammy is working for now ,

and I did not have any issues .

If anyone also installed 22.04 , please write about your experience or

possible problems here .

[SaicharanKandukuri]

Jammy:raw? you installed DE right?

[XingyanHu]

I double-checked. I installed Jammy : raw.

[SaicharanKandukuri]

I mean the xfce4 packages in jammy:raw
You installed them right?

like

apt install -y xubuntu-desktop

[SaicharanKandukuri]

if yes then try to run it manually without script and try to look for logs and post them here

[XingyanHu]

Thank you for you reminding. I didn't install xfce4-session, that's the reason. Then I rewrote the script. For now, everything goes well. Thank you again, you really help a lot.

[v8karlo]

Updated : ( edited first post )

How to remove and disable snap and install latest Firefox .

xubuntu-desktop is not recomended to install .
Without it , 22.04 crash much less .

[hello-smile6]

Would this work without dbus or systemd on the host?

[SaicharanKandukuri]

yep!

[hello-smile6]

Do I need more than 800 megabytes to install?

[v8karlo]

I will use this version until Udroid officialy releases Udroid 22.04 Jammy .

[v8karlo]

Installed Eclipse for Java

https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/2022-06/R/eclipse-java-2022-06-R-linux-gtk-aarch64.tar.gz

And made simple Gui project creating a single window .
It seems that it is working .

Paste and go this link into Browser, it will download Arm64 Eclipse to Downloads dir in Jammy .
https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/2022-06/R/eclipse-jee-2022-06-R-linux-gtk-aarch64.tar.gz&r=1

and from XFCE4 Terminal unpack and start Eclipse [ Can be unpacked from file manager too ] .

cd Downloads

tar -xvf eclipse-jee-2022-06-R-linux-gtk-aarch64.tar.gz

cd eclipse

sudo ./eclipse

Move dir Eclipse where you want it to be from Downloads .
and create Desktop Launcher which is pointing to that working dir Eclipse .
Eclipse icon is inside Eclipse dir - for Eclipse Launcher .

On Eclipse under Help there is Eclipse marketplace .

When window is open type windowbuilder in find and install it for GUI projects .

Install only windowbuilder 1.9.8 ( first one ) at first , otherwise it will cause non-working windowbuilder .
Later , when everything is working install the rest .

Functional Eclipse IDE with working WindowBuilder .

Functional Eclipse IDE with working WindowBuilder .

Does anyone else tried to code with Eclipse under proot without any errors ?

If does what is to be expected ?

Is it usable under Udroid because of proot ?

[ghost]

just tested, worked perfectly for me. time for Android studio

[v8karlo]

Hehe , hi Sam !

I did not expect it to work , but it suprised me !

[ghost]

hi too, actually it worked last time (8 months ago) not in proot-distro. android studio works too , have a try

VS CODE RUNS ON ANY BROWSER IN ANDROID

OR

ANY BROWSER IN JAMMY VIA TERMUX

In Termux type :

proot-distro login udroid-jammy-raw --shared-tmp

You are now in root@localhost:~#

Install wget npm nodejs git

apt update && apt upgrade

apt install wget npm nodejs git -y

Download the VS code tar package:

wget https://github.com/cdr/code-server/releases/download/2.1698/code-server2.1698-vsc1.41.1-linux-arm64.tar.gz

tar -xvf ./code-server2.1698-vsc1.41.1-linux-arm64.tar.gz

rm ./code-server2.1698-vsc1.41.1-linux-arm64.tar.gz

cp ./code-server2.1698-vsc1.41.1-linux-arm64/code-server /bin

Start the code server in Termux :

code-server

Open Chrome in DEX and paste and go into browser adress bar :

localhost:8080

Browser screen will prompt you for password .

and copy the password that's generated in Termux to Browser screen prompt
( password looks like this 3ca9c016701bef7ef744f057 and copy it from Termux )

root@localhost:~# code-server
info  Server listening on http://localhost:8080

...
info    - Password is 3ca9c016701bef7ef744f057
...

info      - To use your own password, set the PASSWORD environment variable
info      - To disable use `--auth none`
info    - Not serving HTTPS

On browser screen you will be prompt for a password ,

copy pass from Termux and paste into browser prompt [ 3ca9c016701bef7ef744f057 ]

And there it is VS CODE in your browser .

The whole video how to do it, is here :

VS CODE in Android Chrome on DEX .
In Android it is fast !

ANDROID

If you wanna run VS CODE n Jammy , start VS CODE server in Termux ,
open new session in Termux and start X:11 .

Open Mozilla , go to localhost:8080 , enter pass from Termux and

enjoy !

JAMMY

Next time to start VS CODE procedure is :

Termux :

proot-distro login udroid-jammy-raw --shared-tmp

code-server

Browser :

Start localhost:8080 in browser adress bar .

Copy pass from Termux to browser screen bar ,

[JGM113]

We can run vs code natively in Ubuntu. Download and install from microsoft .deb ARM64 version then nano /usr/share/applications/code.desktop and add --no-sandbox to both exec lines.

Even live server works-

[v8karlo]

Excelent !

I don't have panel in my XFCE, but everything else is working just fine.
Thanks for this nice guide.

[anonimo82]

How can I have panel with menu and open windows?

[v8karlo]

I dont know , I had panels after install .

Maybe xfce4 did not install correctly ?

[anonimo82]

Ok, problem was I didn't install xubuntu-desktop. Now I did and everything works, except I get a crash on XFCE loading, which closes all my open Apps on my device. SM-G965F, with Android Q (Stock ROM)
Note I fully followed the guide, step by step.

Edit: Ok, I redid everything from scratch, without installing xubuntu-desktop. I still have crash bug, but I have panel now.
I did everything the guide told me to do

[v8karlo]

If termux-x11 crash and can not start ,
I found it useful to clear cache on termux-x11 .

Right click on termux-11 , app info , storage , clear cache .
And it is working again .

[v8karlo]

.

It is not my project .

Thanks to Mr. Kandukuri and Mr. Sam !
Without them nothing of this would be possible .
It is their project , you can visit their project homepage :

https://github.com/RandomCoderOrg/ubuntu-on-android

Or for more info you can join their Discord channel and ask them there :

https://discord.com/invite/h7wZ9BfbU9

All info I got from them and lots of support and help !

However , I am C# Windows programmer , so ,
some things are understandable by itself .

I am totally NOOB in Linux , and just starting !

For any help or techical queston you should ask them ,
because I dont know much stuff just as you !

I wrote this guide because when I fist come here I was lost ,
and there was no detailed guide .
It took time until I managed to run termux-x11 .

That was my motivation to write all of guides for stuff ,

so new quests wont be lost like me !

Here on disscussion page you can find useful infos .

https://github.com/RandomCoderOrg/ubuntu-on-android/discussions

[devourer66]

Unfortunately, Termux-x11 displays a blank screen without console input for me. Progressing further through steps leads to termux-x11 crash. Clearing cache does not help.
Any ideas on how to troubleshoot this?
I'm on Android 12

[HossamSalah00]

I am using Ubuntu Jammy on daily basis along with Android software and I don't miss my computer and laptop at home .

They are both collecting dust for now .

At my work is different situation because I need very powerfull machine , which is another case , so PC must be used , but for everything else ... My phone is just fine .

I carry it wherever I go , internet is integrated , lots of sensors , cameras ... It is very different than laptop , and way to more practical .

And UDROID enabled free software , so I have everything in one . There is no limit to that .

Lots of my friends at work are puzzled when I show them , even that they are in programming waters and following trends , they never realized potential of what can be done with mobiles .

Everything I ever wrote here is made on my mobile , keyboard , mouse , large monitor , just as on PC , it is even easier to do it on mobile than on PC . Everything is integrated and orientatated toward communication , which makes things simpler .

I can not answer call on a laptop while watching movie , but on mobile it will pause movie automatically and receive the call on speaker . End call and it will resume movie . I just like the concept so much ! And lots of other things ... It is just superior idea compared to laptop .

Have you tried wine or lutris to do lite gaming?

[v8karlo]

No , not really .

I am not a lot into games and what Android Play Store offers is enough for me .

I like Diablo series from my younger days and even now like to play them or similar .

For something more serious like Eve Online , which I played for years , I use my PC .

That is actually good thing about that mixing of operating systems ( Android and Ubuntu ) which DEX is providing ( visually , it is present without DEX as well ),

that I use games in Android where GUI is native and fast and using Ubuntu for stuff not dependent on fast accelerated GUI .

And thanks to DEX visually have them all on one desktop .

But will try Wine to see what it offers !

As I understand Wine is emulator and slowing down things ,

and that is reason why did not tried it till now .

But , will try to use it .

This project Ubuntu on Android occupies me for now because I can explore Linux world for a bit ,

( on mobile I was forced to switch to Linux and leave Windows , and I like it ) ,

which I never used before in some serious manners .

And it got me !

[v8karlo]

Hossam001-bot your SOLUTION for starting Termux-x11 is way better ,
and I included it into first post , guide .

If you have some other solutions around Termux-x11 please share .

Thanks !

It removed some problems I had with old way of starting Termux-x11 .

It starts Termux-x11 from first try , which was not the case before .

I don't know exactly why , because on first look it is the same commands just in one line ,

except the switches in your solution for which I don't know what they does .

But it works good !

you are welcome!
I think it is Termux problem or it's not I don't know because when i type (su ime set com.touchtype.swiftkey/com.touchtype.KeyboardService), it excutes only su and not command after(fixed it by su -c command) . So i thought it is same problem with Termux:x-11.

[v8karlo]

Issue with starting Termux-x11 is gone .
It starts from first try and on exit it throws me directly in Termux ,
I don't have to type exit ... exit .

Excellent !

Now it works as supposed to .

[namyunseong97]

thank you for your project.
by the way, I want to use lxqt in lieu of xfce.

Do you have any idea for using lxqt?

[SaicharanKandukuri]

yes we do have plans for it

[dontknowhy]

but the DPI scale will be very big because of qt

[SaicharanKandukuri]

we can adjust it with QT variables

( next time you run Termux-x11 there will be no down NAV bar )

Direct input mode has a bug , other two are stable .

termux/termux-x11#118

It is recently implemented and for that is needed to install last successful build of

termux-x11 - app-debug.apk ( install in Android )
termux-x11.deb ( DPKG -i in Termux )

( see first post for installing those two )

The most recent version of Termux-x11 apk and .deb package can be found here

https://github.com/termux/termux-x11/actions/workflows/debug_build.yml

under the Actions tab.

On the left side click on the build ( under All workflows ) and
in the list of workflows click on most recent one , usually on the top of list .

It will open that workflow

and there will be last build , Artifact

Click on termux-x11 and download it to phone Download dir and unzip it .
It contains two files .apk and .deb

On the first post " Installation of Jammy " you will find how to install Termux-X11 .apk and .deb

WITHOUT BOTTOM NAV BAR !

In DEX upper title bar is still visible and annoying .

It should AUTOHIDE like in movie player .

Issue 125

[v8karlo]

The SOLUTION for starting Termux-x11 from Termux by

Hossam001-bot

works way much better . ! ! !

termux-x11 > /dev/null &

pulseaudio --start --load="module-native-protocol-tcp auth-ip-acl=127.0.0.1 auth-anonymous=1" --exit-idle-time=-1

proot-distro login udroid-jammy-raw --shared-tmp -- runuser -l v8 -c 'DISPLAY=:0 xfce4-session'

NOTE : I edited first post and included this solution into guide .

This SOLUTION removed issues I had with starting Termux-x11 .

[JGM113]

Thank you for the guide, it's working much better than the VNC method and I'm really happy with it.

My only issue now is that after a few minutes and seemingly randomly termux-x11 will crash and in termux I get this error:

[JimmyNeutronsBitch]

I've tried both methods, I've done it constantly, deleted and reinstalled, and I've been meeting a blank screen every time. I don't know what's happening.

[v8karlo]

Maybe this is related :

termux/termux-x11#129 (comment)

Build 174 of Termux-x11 could be issue ?

I am using older Build .

[ThatMG393]

@v8karlo Can you send me a link of your current Termux build and Termux:X11 build please?

[ThatMG393]

Maybe this will help: #152

[v8karlo]

termux/termux-x11#129 (comment)

[v8karlo]

I noticed a strange behavior .

If Termux is pinned to be always on top of applications Termux-x11 starts from first try .

In DEX pin for ALWAYS ON TOP is icon pin .

If the Termux has focus always on top Termux-x11 starts normally !

If it is not on top it won't start from first try ?
[ Sometimes it does , but rare ]

So that issue could be related how Android handles apps ?

NOW , IF TERMUX IS WITHOUT ALWAYS ON TOP [ FOCUS ] WHEN STARTING TERMUX-X11 I GOT BLACK SCREEN .

Message : Another instance took over . Leaving ...

Another try Without Always on top of Termux .
Message is not the same , different reason but could not connect and BLACK SCREEN on Termux-x11 .

Messages for failure are many , but results with black screen !

I TESTED THIS MANY TIMES AND ALWAYS THE SAME HAPPENED !

I am not using the latest Build of Termux-x11 , but one from 2 months ago , [ Using Android 12 ] !

Anyone noticed this ???

COULD BE ANDROID HANDLING APPS ISSUE ?

[op06072]

Can I use kde?

[SaicharanKandukuri]

You can

[op06072]

I can't use even xfce4. It run normally but after about a minute termux stop with signal 9.

[SaicharanKandukuri]

I publish a video to fix this issue
Meanwhile check #123

MEMORY ALLOCATION WHEN USING JAMMY

While using various apps on Android , DEX and
starting X-11 with apps running

Libre Office
GIMP
Firefox
Eclipse
XFCE Terminal

memory usage was very high 8.02 GB of 12 GB was used .
Aldo all apps were running fine and Jammy was stable .

sudo apt install htop

From terminal type htop to see system usage .

Then I went back to Android and clean memory via Device care after which Jammy was running at only 4.71 GB .

It could be good practice to clean memory before using Jammy in order to reduce system stress .

Android App Device Care / Memory

Before cleaning there is option to exclude apps from terminating [ very usefull ]

This way memory cleaner wont terminate Termux and Termux- X11 [ TX11 ]

4.71 GB allocated after memory clean up .

[v8karlo]

For the message shown in Jammy terminal when started

groups: cannot find name for group ID 1079

Solution is , type in terminal >

touch ~/.hushlogin

[v8karlo]

See [ Season 03 E01 ]
Player VLC [ Full Screen ]
Samsung S20 12GB

Video is 1080p .

Wanted to see if proot Jammy can play movie , and is very watchable in Full Screen .
I am surprised !

This page is most seen in udroid
Nice work @v8karlo 🎉

[v8karlo]

It is not mine project , it is your project , as well as this page .
But I wanted to make tutorial so more and more people can
start to use Udroid .
When many people use Udroid then project grow faster and develop faster .
My intention is to contribute to faster development of Udroid and X11 as well .

You started all of this and I just helped by attracting more users .
With more users maybe it will be easier for you to develop it further , I hope .

So , thank you !

BleachBit [ Cleaning Software ]

It seems that is working in proot . I did only one run successfully and it passed without errors .

BleachBit recovered around 1,1 GB in my system .

Lots of apps which tempering on system in proot results in crash and errors .

If you dont have Installed Nala substitute Nala with Apt .

sudo nala install bleachbit

System [ 265 MB recovered ]

It passed Office and Firefox cleaning as well . Nothing crashed .

DeepScan went well . [ Slow ]

Apt and Bash [ 833 MB recovered ] . No crash .

UNINSTALL WITH NALA

sudo nala history

sudo nala history undo 23

[ in my case is 23 from Nala history list ]

You can also use REDO in Nala History .

After cleaning i made backup of distro and my distro with all above and more apps is 2,7 GB .

Hello

[v8karlo]

Hi !

[v8karlo]

[pecbraz]

Thanks very much for this tutorial, I have it now working in Samsung Z Fold 4, and it's amazing!

Anyone tried to install Intellij IDEA? They have instructions here:
https://youtrack.jetbrains.com/articles/IDEA-A-48/JetBrains-IDEs-on-AArch64

[pecbraz]

ok, I just did it and it works!
Only a minor issue about fsnotifier not working which makes filesystem changes slow to update on intellij, but I can live with that...

[v8karlo]

If you have any technical questions goto discord Udroid channel

https://discord.com/invite/h7wZ9BfbU9

and ask Zman author of Udroid project .

If there is anyone who can help you or quide you, its him !

Samsung S20 DEX

Full screen without upper Nav Bar [ how to remove down Nav Bar is in previous posts ]

Install X11 Build#196 [ Enables Full Screen ]
https://github.com/termux/termux-x11/actions/runs/3065627748

Enabled Force Desktop Mode [ Experimental Desktop mode on secondary displays ]
Restart DEX [ X11 Build#196 installed ] and start X11

[pecbraz]

What is the difference of activating Force Desktop Mode versus just using DEX without it?

[v8karlo]

It is a little bit hard to explain, so maybe it is better to read this :

termux/termux-x11#158

It will explain a lot . There are some Android behaviours which can not be avoided ,

so it is hard to follow the rules and have the best results . Read it .

Android is dictating the rules . it is not VM so you have access to everything .

It is hack which provides empty space where they put Linux inside Android and there lies the problems .

Some can be solved , but some can not be broken .

[pecbraz]

I got it to work, but the colors are all lighter/brighter on fullscreen and it's very noticiable. For example, black turn into grey... do you have this issue also?

[v8karlo]

Yes , the screensaver I use is only black screen but is grey at night .

I never tun off my phone and my momitor , and at night is grey instead of black !

[Root56346]

can i use an alternative to dex? like the sentido desktop?`

[v8karlo]

I am using DEX for mixing Android and Linux software a lot .

DEX allow that and that is great .

Linux and Android browser for example . The Linux theme is a little bit lighter , but who cares ?

I am using Libre office in Linux and play games on DEX [ example only ] . Both OS'es together are powerfull combination !

And DEX is making it possible .

It works !

DEX is nothing special , only window menager .

But as the window manager it is doing excellent job mixing all Android and Linux windows

just as they are one OS . You can work in both at the same time like they are one and same !

That is the power of DEX !

I can watch the movie on DEX player while writing in Libre Office on Linux just as they are one OS . !

I dont need to watch movie on Linux because X11 is too slow , and I dont need too . I have DEX for that .

But DEX does not have Libre Office ?

But both together ???

[Habicht97]

Everytime I try to start xwayland it says, there is already a server running. the Problem is I cant exit Termux x11 because I hjave no notification for it. Is there a way to kill the Wayland server? Another fact which I dont know if its a problem or not is that im login to jammy not through proot but through udroid directly. Starting through proot is unfortunatly not working.

[ThatMG393]

You can kill the Xwayland server by running this outside the proot: pkill -9 xwayland.
And it's not a problem because UDroid (only scripts) got revamped. You can do udroid [command] -h to display optional arguments

[Habicht97]

Is there a way to passthrough Input and Output devices? Since Discord on Mobile is really a mess with Input Output devices.

[SaicharanKandukuri]

No, ( least not yet )
