Graphical glitches with Arc A770 on Kubuntu 22.04

[lrussell887]

I just received my Arc A770 16 GB and confirmed everything is working normally with Windows 11. I wanted to use the card with my existing Kubuntu installation, so I followed the Intel installation guide (https://dgpu-docs.intel.com/installation-guides/ubuntu/ubuntu-jammy-arc.html). Everything seemed to install normally, but after rebooting the graphics are as seen in the attached video, from the moment the cursor and login screen appear. I've attached the results from the verification steps in the installation in drivers.txt, as well as more detailed system information in system.txt. I should note that the results are the same whether I have one or both monitors connected. I also confirmed applications that capture the desktop such as screenshots or screen sharing work normally. Please let me know if there's anything more I can provide or if anyone has any suggestions.

Thank you!

Hello lrussell887, 

Were you able to check the information from the link provided?

• Does it happen while using the OS as the main OS, virtualized, dual boot?
• Is there something that triggers it or just when boots the OS? 
• Have you tested the same Intel® Arc™ A770 Graphics (8GB) in other system and same Linux distro?

Best regards,

Hello lrussel887,

I can confirm that I faced the same issue with Kubuntu 22.04

The colors looked exactly as your image and video.

Since it was a fresh Kubuntu install, I overwrote it with a Ubuntu installion.

After finishing the driver setup with the same link as you (https://dgpu-docs.intel.com/installation-guides/ubuntu/ubuntu-jammy-arc.html) I found no issues with the display.

This suggests that it's a Kubuntu specific issue and perhaps related to kde? 
I am not entirely sure, sadly I am not savvy enough to figure it out by myself.

Cheers

I have the exact same issue, the graphics look like an LSD trip on that kernel, but works fine on any other kernel. I recommend downloading the latest using mainline. Also put the line GRUB_CMDLINE_LINUX_DEFAULT="i915.force_probe=56a0" into your /etc/default/grub and run update-grub, but replace 56a0 with whatever your gpu says using 'lspci -nn | grep VGA' which output 8086:56a0 for me

Though I do want to get this working to use oneapi so I can use pytorch, which does not work on the other kernels which says "ERROR: intel_extension_for_pytorch-1.10.200+gpu-cp39-cp39-linux_x86_64.whl is not a supported wheel on this platform" because the kernel modules cannot be installed on anything other than the kernel provided.

A770, Kubuntu 22.04

Thanks for letting me know how to fix the LSD-like effects.

However, like you, I want to get oneapi working to test out the A770's pytorch capabilities...

I guess one option would be to just switch to regular Ubuntu... although I heard you can replicate the LSD-like effects when you switch from Wayland to X11 even on vanilla Ubuntu.
