gpu.

SUMMARY
After update I am forced to use singlemonitor because if I try to login (or
connect when already logged in) the second monitor, I get a black screen. I am
fortunately able to go to another tty session. Do note that this started
happening when I updated to the latest version.
STEPS TO REPRODUCE
1. Connect two monitors to (AMD?) gpu
2. Log in into your account
3. Observe the black screen
OBSERVED RESULT
Black screen on both screens then it cuts connection to both displays.
