Visual artifacts

[maa7]

Hello,

With these HDMI graphics cards Asus EN210 Silent Zotac 8400GS and VMware Horizon client i see visual artifacts like this:

[Doncuppjr]

Looks like a mesa or acceleration issue. Are you on the latest commit? Anything about firmware in the journal?

[maa7]

>>Are you on the latest commit? Yes

>>Anything about firmware in the journal? where should i watch it?

[Doncuppjr]

go to a root shell, and run journalctl -xe |grep -ie firmware

[maa7]

How to go to a root shell?

[maa7]

[Thinstation]

Send the file /var/log/Xorg.0.log

[maa7]

Xorg.0.log

[Thinstation]

Try a build without package xorg7-nouveau

[maa7]

[Thinstation]

That’s a different issue, or you have bad ram.

are you talking about video ram, or system ram?

[maa7]

I tested system memory and found no errors

[Thinstation]

I can't image any link between xorg7-nouveau and a kernel panic on boot. The two are just not related in any way.

[maa7]

kernel panic not because of the xorg7-nouveau, but because of the xorg7_nvidia

[Thinstation]

I'm sure that package needs some attention. I would avoid it as well. If you had that package in, that would explain your artifacts. Nvidia replaces some of the systems 3d components.

[maa7]

Issue cannot be fixed and should I replace these video cards as incompatible?

[Thinstation]

Do you get the artifacts when using kms framebuffer instead of nouveau or nvidia.

[maa7]

how to use kms framebuffer?

[Thinstation]

Make sure neither Xorg7-nouveau or nvidia packages are in the build. Xorg should fallback to framebuffer.

I already tried this

[Doncuppjr]

Send that Xorg.0.log

[maa7]

Xorg.0.log

[Doncuppjr]

Here is the clue Failed to load /usr/lib/xorg/modules/extensions/libglx.so: libGL.so.1: cannot open shared object file: No such file or directory

For some reason, libGL.so.1 is missing. Might be the nvidia package. Try removing that.

[Thinstation]

If you ever tried using the xorg7_nvidia package, it may have broken your chroot environment and all builds you make with it. I would save your configs, nuke your unwind, and then unwind again.

[maa7]

I tried to reinstall, but build with latest version Thinstation hangs after installing Horizon Client:

[maa7]

Can you fix this issue in the next release?

[Thinstation]

I can not reproduce the issue.

[maa7]

copy thinstation-6.2-Stable.tar.gz to linux machine unpack rename folder to "thinstation" cd thinstation sudo ./setup-chroot cd /build ./build --allmodules --savedir

I tried three times, and all three times the build hung after Horizon Client 8.4 installation (the previous release with Horizon Client 8.3.1 builds without problems)

[Thinstation]

The Horizon Client is installed while a full strace is being made. All of the logs for the install can be found at build/packages/vmview/build/vmware-log/ It does take a while to install, and it does appear to hang, but it will eventually finish. Maybe add more CPU and Memory. build.log

When xorg7-nouveau and xorg7_nvidia disabled, the picture looks normal and without artifacts. But i have some questions: 1) what are the disadvantages of this mode? 2) why xorg7-nouveau have visual artifacts? and can it be fixed in the future? 3) why xorg7_nvidia do not work? and can it be fixed in the future?

[Thinstation]

Nouveau should not have artifacts if you never install _nvidia.

The disadvantage of the modeset driver is that it is generic and unaccelerated

The Nvidia is very rude and steps all over the system. It could be fixed, but it’s not a priority.

>>Nouveau should not have artifacts if you never install nvidia I didn't install xorg7_nvidia, but Nouveau have artifacts

[Thinstation]

It has basic scroll buffer. Swrast for 3d

I found a patch for nouveau that might help you. Try the latest commit.

[maa7]

Latest version also has some visual artifacts (question - how to take screenshots in Thinstation?)

Xorg.0.log

[Thinstation]

You can use the scapy package.
