Bug#1109116:

["Aaron Brooks" <aaron@zsh.rocks>]

I'm experiencing this bug too, looks like i915 has been changed/updated to include the new xe driver and it's broken.

dmesg:

[    2.740670] xe 0000:01:00.0: Your graphics device 56a6 is not officially supported

               by xe driver in this kernel version. To force Xe probe,

               use xe.force_probe='56a6' and i915.force_probe='!56a6'

               module parameters or CONFIG_DRM_XE_FORCE_PROBE='56a6' and

               CONFIG_DRM_I915_FORCE_PROBE='!56a6' configuration options.

$ intel_gpu_top

No device filter specified and no discrete/integrated i915 devices found

$ lspci | grep DG2

01:00.0 VGA compatible controller: Intel Corporation DG2 [Arc A310] (rev 05)

02:00.0 Audio device: Intel Corporation DG2 Audio Controller

blacklisting the xe module makes the dmesg error go away but the gpu still isn't available for use. My GPU is an Intel Arc A310.
