Similar issue for Dual Discrete Display card AMD+GeForce
I wanna blacklist nouveau for the Geforce VGA Passthrough via VFIO
but then the screen on ATI is flickering on the tty login screen but not to
Gnome. The keyboard NUM lock light is flickering as well and it is hard to work
for typing the password
After flickering for a while, my keyboard works normally and I can login in
However the screen flickers again when I type service gdm restart, I
still fail to get in GNOME.
