Public bug reported:
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 reb
oot 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.
Thank you
