Thank you for the response. > xe.enable_psr=0
This alone does not fix the flickers on my ThinkPad X1 Carbon Gen 14. It turns out that putting any of the following in /etc/default/grub can fix the flickers. Of course, one has to `sudo update-grub` and then reboot. ``` GRUB_CMDLINE_LINUX_DEFAULT="xe.enable_psr2_sel_fetch=0 xe.enable_panel_replay=0" # Disable selective PSR2 fetch and PR. ``` ``` GRUB_CMDLINE_LINUX_DEFAULT="xe.enable_psr=1 xe.enable_panel_replay=0" # Disable PSR2 and PR. ``` ``` GRUB_CMDLINE_LINUX_DEFAULT="xe.enable_psr=0 xe.enable_panel_replay=0" # Disable PSR and PR. ``` It would be great if there is a more fundamental solution.
