Intel Repos broke my OS (Pop_OS)

[cement_head]

Running Pop_OS (22.04 LTS). Attempted to install Intel GPU compute using these instructions: https://dgpu-docs.intel.com/driver/client/overview.html#ubuntu-22.04

Caused total chaos.

How do I uninstall / revert?

I must be doing something horribly wrong, but I've been using LINUX for over fifteen years, and never seen such a destructive repos as INTEL.  Had to wipe my install and reinstall - hopelessly broken and no reversion capacity.

What I was trying to do was to insure I had the latest available INTEL ARC Xe driver for my GPU (B580) - is that driver already in the kernel driver (6.12.x)?

Hi cement_head,

Thank you for the update. I will investigate this and will get back to you once a resolution is available. Thank you for your patience and understanding.

Okay, got the card. Looks as if the XE driver is being loaded and is running as expected. (Using the distro's Pop!_OS intel-media-va-non-free driver).

Running a System76 DarterPro (darp10-b) with a Razer Core and an upgraded PSU (Corsair 750W); card is a guinine Intel ARC B580 running the internal laptop display via a TB3/4 cable.

Machine was extremely laggy for the first five minutes and magically "smoothed out" - not sure if something was being compiled in the background but it seemed as if it was busy (CPU).

Settings on games are one step (High > Medium) from an NVIDIA 3060Ti card, then I get same FPS (60 fps).

Actually, the MTL = Meteor Lake, so that wasn't it.

Using the egpu-switcher script from here: https://github.com/hertg/egpu-switcher

I had to make a custom x11-template.conf file and save it to /usr/share/egpu-switcher

I used the instructions on the GitHub page for egpu-switcher script, along with the information here on the Debian WIKI: https://wiki.debian.org/ExternalGpu

I've set up the script to have the B580 handle all the rendering and then pipe the X Screen back to the iGPU of the laptop via the TB3/TB4 cable.  I use LACT [https://github.com/ilya-zlobintsev/LACT] to double check that the ReBAR is enabled for the B580 after booting.  I usually (on my laptop) plug the TB3/TB4 cable into the laptop just as the System76 splash screen is displayed.

Here's my custom config file:

# manual conf for B580 and egpu-switcher

Load "modesetting"

Hi cement_head,

To assist you further, I recommend removing all Intel drivers using the following command: sudo apt-get remove --purge '^Intel-.'*

Please note that we only support Ubuntu versions 25.04, 24.04, and 22.04. Our PPA has been thoroughly tested and works correctly with these versions. Additionally, ensure that no other third-party graphics drivers, such as Nvidia drivers, are loaded to prevent any conflicts. If the issue persists, you might consider performing a clean OS installation.

It's important to mention that using the Arc GPU through an external enclosure is not a supported use case for this GPU. Therefore, in the event of an error or issue, it is unlikely to be investigated further.

Could you please confirm if the issue has already been resolved?
