Use Xorg with HDMI?

[pdp7]

Several questions from Slack and Forum:
@tekkamanninja
Is it possible to use Xwindows with the current HDMI output?

Hi David,
I'm trying to use xorg but I'm getting a black screen when launching xorg on the fedora image.

Thanks.

[pdp7]

@sdanfa I have not gotten any confirmation from starfive in my weekly meetings that Xwindows is expected to work yet.

@david-Li-93 hello, where did you get this information from? are you with starfive?

@MichaelZhuxx @tekkamanninja do you have an example of XWindows working on the StarFive JH7100 either with the EVB or the BeagleV beta prototype?

[david-Li-93]

Dear pdp7 && sdanfa
* I am an employee of starfive, responsible for the display driver.
* Our Linux display system currently uses a framebuffer architecture，and It supports graphical desktop systems
* Looking at the error,It's not a problem with our platform，It's up to the developers to solve this problem，

[david-Li-93]

Dear sir
We don't use the GPU on our hardware, so it might be a problem if the graphics desktop relies on the GPU。

@MichaelZhuxx @tekkamanninja @david-Li-93 is this a problem with how Xorg is configured in the Fedora image then?

@david-Li-93 Which developers do you mean? @tekkamanninja?

[david-Li-93]

Dear sir
* is this a problem with how Xorg is configured in the Fedora image then?
==》sir,Xorg is an implementation of X11 that also provides an X Server for Fedora Linux operations。
==》We do not support configuration for Xorg
* Which developers do you mean?
==》 I'm sorry. What I mean is that this problem needs to be solved by the R&D engineers themselves

[david-Li-93]

Our team is trying to do a desktop system,
If there is a solution to this problem, we will share it with you。

[pdp7]

@tekkamanninja tells me that Xorg is working for remote sessions in the new Fedora image which should be uploaded soon, I will update when that has happened.

There is a problem where Xorg will not work over HDMI as the fbdev is not working correctly. This is still being investigated by StarFive.

[MichaelZhuxx]

We have solved the issue over HDMI and will released in next Fedora image, stay tuned.

[pdp7]

@MichaelZhuxx @tekkamanninja where are the commits that fix this issue?

@kraj wants to pull it into yocto/oe meta-riscv layer https://github.com/riscv/meta-riscv/blob/master/conf/machine/beaglev-starlight-jh7100.conf

[pdp7]

@esmil @geertu @tpetazzoni @kraj:
I learned from @tekkamanninja that this commit fixes the problem with being able to display Xorg on HDMI:
starfive-tech/linux@e865a75

FYI - the StarFive Koji Fedora sever is now online. The latest Fedora image can be downloaded for testing. XFCE does work over remote SSH session but it does need the kernel updated with the above fix for XFCE to display on the HDMI.

[pdp7]

The new May 16 Fedora image now has XFCE working over HDMI:

Fedora-riscv64-vic7100-xfce-dev-Rawhide-20210516233526.n.0-sda.raw.zst (sha256sum)

This commit is present in esmil's v5.13-rc2, and doesn't fix the issue on both my Sony TV and BenQ monitor.

Hi, guys, I have problem on my StarFive boot Debian XFCE, so slow.

[esmil]

There was recently a user on #debian-riscv talking about Xfce on Debian being slow, but not on the Fedora image. I suggested that it was probably some userspace configuration then. They returned and said Xfce on Ubuntu also worked much better, so maybe you can compare their default configurations / versions.

Thanks, you means Linux kernel userspace configure?

[esmil]

No userspace. They said they were using the same kernel, but Xfce was slow on Debian and fast on Ubuntu.

Thank you, I will try to make a Ubuntu .img on my starfive visionfive v1

I have been test on Gentoo RISC-V, xfce working great.
