Bug Description
OS: Ubuntu Gnome 14.04 Trusty (latest upgrade)
Hardware: Asus U36JC
Graphic Driver: nvidia-331
I have opened a bug #1296020 (Non-existent display detected in both intel driver and nvidia driver).
Except the non-existent display issue, nvidia-settings can not detect any real displays. The only display/monitor it can detect is the non-existent one. I think this should be a different bug for nvidia-331.
For "xrandr -q" output, please refer to bug #1296020. nvidia-settings becomes useless now, it can not detect the built-in display and it can not detect any new external display. It can only detect the non-existent CRT-0 (VGA-0). Gnome control center --> Display can detect all displays. (but it fails to rotate external VGA display. not sure if this is another bug or not).
I will attach two screenshots for nvidia-settings and gnome-control-
NOTE: due to the bug #1296020 and gdm flickering issue, I have added the following section to xorg.conf:
Section "Monitor"
Identifier "VGA-0"
Option "Ignore" "True"
EndSection
AND, xorg.conf is auto-generated by some package. I never created it manually. It might be generated by gpu-manager (I was told).
