@Itai-Nelken Try adding the --allow-downgrades flag to line 487 of the vdesktop script.

I think the problem is that the .deb's are 32bit, Is there a way to install them from apt?

Botspot · 2020-11-28T16:37:42Z

Maybe libepoxy-dev and libepoxy0 are available on the arm64 repositories. Try installing them with apt.

Botspot · 2020-11-28T16:38:11Z

I can add a logic switch to skip downloading these packages if those 2 packages are already installed.

Botspot · 2020-11-28T16:42:46Z

Or, if you wanted to, you can disable virgl. and use vdesktop without it.

ENABLE_VIRGL=no vdesktop /dev/sdb gui

works, thanks. btw what is virgl?

VirGL is a virtual GPU that connects with the guest. It provides OpenGL hardware acceleration to supported applications.

@Itai-Nelken I'm still curious: On your system, does this command work okay?

sudo apt install libepoxy-dev libepoxy0

If it does work, I can make changes to vdesktop to make virgl work on 64 bit systems like yours.

Itai-Nelken · 2020-11-28T16:55:45Z

libepoxy0 installs allright, but libepoxy-dev fails with the same error: dpkg: error processing archive /tmp/apt-dpkg-install-lFng30/10-libepoxy-dev_1.5.
4-1_arm64.deb (--unpack):

Itai-Nelken · 2020-11-28T16:58:58Z

but I think it's something with my system

Botspot · 2020-11-28T16:59:33Z

Maybe try sudo apt-get clean

Itai-Nelken · 2020-11-28T17:02:09Z

still same error when installing libepoxy-dev

Itai-Nelken · 2020-11-28T17:03:16Z

running sudo apt install libepoxy-dev:armhf works

Itai-Nelken · 2020-11-28T17:14:03Z

I removed the lines that download and install libepoxy-dev and libepoxy0, and I got this error:

how do I fix it?

Itai-Nelken · 2020-11-28T18:03:52Z

I need to change any instances of sudo -u pi to sudo -u $USER.

I did that with the 'find and replace' function of the text editor

Itai-Nelken · 2020-11-28T18:08:11Z

fixed it with sudo -E ldconfig

might be a good idea to add it to the vdesktop script instead of ldconfig as long as it works on rpiOS

I'm writing how I installed all the apps I use on Ubuntu that aren't available in the repositories here if you would like to take a look.
(first app is pi-apps, and I added the way I installed vdesktop there)

Itai-Nelken · 2020-12-05T18:13:42Z

could you change all sudo -u pi to sudo -u $USER please?

Botspot · 2020-12-05T22:12:23Z

could you change all sudo -u pi to sudo -u $USER please?

Ah yes, thank you for reminding me.

Itai-Nelken · 2020-12-06T08:57:54Z

I think desktop generally doesn't work that well on Ubuntu, a few days ago I tried to boot a fresh install of rpiOS, and the rpiOS sort of became a "live wallpaper", the Gnome shell became white and crashed after a while. the system was really unstable until I rebooted.
I also had the problem with the XFCE panel applets in TwisterOS.
so maybe add a note about Ubuntu to the readme until enough issues are resolved to make it work ok at least on Ubuntu? maybe something like this:

NOTE:
currently vdesktop doesn't work well in GUI mode on Ubuntu.

and maybe add a link to the part where I wrote how to install desktop on Ubuntu in my Ubuntu-on-rpi-fixes.

CLI mode works perfectly well, you don't even have to do anything. just use desktop the regular way. it's the GUI mode that doesn't work well (on Ubuntu).

Botspot · 2020-12-06T14:02:47Z

@Itai-Nelken I could add a statement to vdesktop's page, or I could fix vdesktop on Ubuntu.

Now, I've not used Ubuntu much. An I've heard that there are several flavors. Which one are you using?

Itai-Nelken · 2020-12-06T14:08:59Z

I'm using stock Ubuntu 20.10 https://ubuntu.com/download/raspberry-pi

I meant to put the statement until it's fixed, just so people know. it could be maybe something like "vdesktop has some bugs on Ubuntu when using GUI mode, a fix is being worked on"

Itai-Nelken · 2020-12-06T14:56:56Z

if you flash Ubuntu, could you try my scripts here please? https://github.com/Itai-Nelken/Ubuntu-on-rpi-fixes

I need someone with a fresh Ubuntu install on the pi to test it, to download and run:
1)git clone https://github.com/Itai-Nelken/Ubuntu-on-rpi-fixes.git
2)cd Ubuntu-on-rpi-fixes/scripts
3)sudo chmod +x main.sh
4)./main.sh

Botspot · 2020-12-06T21:05:44Z

Which Ubuntu release would you prefer I try?

Ubuntu Server 20.04.1 LTS
Ubuntu Desktop 20.10
Ubuntu Server 20.10

Botspot · 2020-12-07T02:48:35Z

There, I added the instability warning to the readme. 5e70caa

Itai-Nelken · 2020-12-07T05:14:04Z

Which Ubuntu release would you prefer I try?

Ubuntu Server 20.04.1 LTS

Ubuntu Desktop 20.10

Ubuntu Server 20.10

for what? use Ubuntu Desktop 20.10 in my opinion (it's the only version with an actual desktop), but you can also use Ubuntu server and use Desktopify to add a Desktop.
personally I would recommend Ubuntu 20.10 Desktop.

just keep in mind it uses about 1.8gb idle, so at least 4gb pi4 if you want to actually use it and test stuff on it.

I also have a bug that makes it use 100% cpu when starting up, so what I did is install bleachbit (sudo apt install bleachbit) and select almost everything, and clean, than open bleachbit as root and do the same, it seems to fix the issue.
you can also try to kill evolution-calendar-factory-notify or something like that, it consumes a lot of resources. if you plan to use Ubuntu Software (snap-store) don't, use Gnome software instead using the instructions here.

Use the fixes here: https://github.com/Itai-Nelken/Ubuntu-on-rpi-fixes

I think that after installing zoom (that install pulse audio armhf) sound became choppy, I have a fix there.

Hope this helps.

Botspot · 2020-12-07T14:16:59Z

The 100% CPU may be caused by the compositor. Just a thought.

Itai-Nelken · 2020-12-07T14:35:40Z

maybe, anyway it settles after some time. I actually think it's because it is running startup tasks because it settles down later, but one CPU core stays at 100% all the time. so maybe.
