Ok, looks like I see what's happening: 1. I boot the laptop after cold-reboot and it crashes during xorg startup and shows on VT: i915 0000:04:00.0: [drm] *ERROR* Writing dc state to 0x1 failed, now 0x0 i915 0000:04:00.0: [drm] *ERROR* DC state mismatch (0x1 -> 0x0)
2. It starts in 5sec-1min up and shows the login screen, then I login and send this first crash: https://errors.ubuntu.com/oops/ea15e7a0-cd06-11ed-9fcb-fa163e993415 (~300KB) 3. Now I executing sequentially the steps to unbind, then bind, then unbind - and it crashes again. 4. I login back and sending this bigger crash log: https://errors.ubuntu.com/oops/a797a552-cd07-11ed-b9a4-fa163ef35206 (~6MB) Now I can find the X crash "Backtrace" in the last crash: [ 98.987] (EE) Backtrace: [ 98.987] (EE) 0: /usr/lib/xorg/Xorg (OsLookupColor+0x139) [0x5610ac7d2809] [ 98.988] (EE) 1: /lib/x86_64-linux-gnu/libc.so.6 (__sigaction+0x50) [0x7f36ec042520] [ 98.990] (EE) 2: ? (?+0x0) [0x0] [ 98.990] (EE) [ 98.990] (EE) Segmentation fault at address 0x0 So I hope it is the one you look for - or I can try to find something else, just describe which additional info I need to look for and I will do that) Maybe journalctl logs or something else?

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.
