You might send a SIGSTOP
signal to Xorg
with
sudo pkill -STOP Xorg
and later send it a SIGCONT
signal.
Domanda
Is it possible to manually freeze the Xorg display server on Linux? If so, how?
This would be for testing purposes. I think that there are a lot of situations this could be useful for, but I currently want to use this to test Linux's ability to recover with SysRq keys from X freezing.
