Yeah I tried to reproduce the same on 5.15 kernel (since it's supported by intel-i915-dkms, 5.19 and 6.1 are not supported and fails on i915 module compilation).
The results are in general the same: https://errors.ubuntu.com/oops/f8d291da-cd9c-11ed-b9ad-fa163ef35206 It's most likely i915 driver, but I'm not sure why Xorg fails on OsLookupColor when the device is disconnected... -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/2012832 Title: Xorg crashes on second and next unbind operations of Arc GPU Status in linux package in Ubuntu: Incomplete Status in xorg-server package in Ubuntu: Incomplete Bug description: Hello folks, Experimenting with new Lenovo Yoga i7 with Intel Arc on board and found that even if it's possible to disable the GPU to save power, Xorg session crashes the session after the second attempt (the first after reboot works just fine). This works like that - after poweroff/poweron of the system I execute the next commands: 1. First attempt: * DRI_PRIME=1 glxinfo | grep 'OpenGL renderer' # Shows: "OpenGL renderer string: Mesa Intel(R) Arc(tm) A370M Graphics (DG2)" * echo -n "0000:04:00.0" | sudo tee /sys/bus/pci/drivers/i915/unbind # Works great * DRI_PRIME=1 glxinfo | grep 'OpenGL renderer' # Shows: "OpenGL renderer string: Mesa Intel(R) Graphics (ADL GT2)", it's embedded graphics * echo -n "0000:04:00.0" | sudo tee /sys/bus/pci/drivers/i915/bind * DRI_PRIME=1 glxinfo | grep 'OpenGL renderer' # Shows: "OpenGL renderer string: Mesa Intel(R) Arc(tm) A370M Graphics (DG2)" 2. Second attempt: * echo -n "0000:04:00.0" | sudo tee /sys/bus/pci/drivers/i915/unbind # Here the Xorg crashes, but I can login again * DRI_PRIME=1 glxinfo | grep 'OpenGL renderer' # Shows: "OpenGL renderer string: Mesa Intel(R) Graphics (ADL GT2)", it's embedded graphics * echo -n "0000:04:00.0" | sudo tee /sys/bus/pci/drivers/i915/bind * DRI_PRIME=1 glxinfo | grep 'OpenGL renderer' # Shows: "OpenGL renderer string: Mesa Intel(R) Arc(tm) A370M Graphics (DG2)" 3. This and the next attempts are just the same as second one I collected the info and can reproduce this state after each reboot, so hopefully it will help you to find what's going wrong during second and next unbind operations. I can always help with additional information if you will need some.
