Bug Description

Video does not appear to be getting set correctly for GDM but seems "corrected" after I login.

Also note that the screen jitters at the GDM login screen.

My video card does not exhibit have any of these issues when I boot into Windows 10.

Sometimes logging in doesn't fix the jittering so I reboot into Windows 10.
