I can't see where Xorg crashed, but it looks like your kernel graphics driver also crashed at about the same time. Can you collect more from around this time in your system log?

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.
