Thank you for pointing that out, Frank. I actually did this in such an order:

  1. sudo grubby --update-kernel /boot/vmlinuz-5.19.8-200.fc36.x86_64 \ --remove-args="i915.enable_psr=0" to undo my grubby stuff.

  2. sudo blsctl cmdline 0 show to check the parameters, i915.enable_psr=0 was gone.

  3. sudo blsctl cmdline 0 set i915.enable_psr=0 to set kernel parameters with blsctl.

  4. Check again with sudo blsctl cmdline 0 show , and i915.enable_psr=0 was there as expected.

Thnaks again for you help! I truly appreciate it.
