Ubuntu 14.04.1 LTS never remember primary screen/monitor resolution

  • 772

I use Ubuntu GNOME with Nvidia graphic card (two HDMI and one DVI output). My monitor is connected through VGA - DVI adapter and work natively in 1920x1080.

  • Since I was unable to change my screen resolution, I spent enormous amount of time to play with xrandr command as well as trying different graphic drivers.

  • I've tried to provide resolution in monitors.xml as suggested here, but it seems that it doesn't help.

Finally, I get it - since Ubuntu didn't recognize my monitor, the only I needed was to edit

sudo gedit /etc/X11/xorg.conf

and set Horizontal and Vertical refreshing rate.

After restart, I was able to finally change my monitor resolution in both - gnome-control-center as well as 'NVIDIA X Server Settings'. There was no error, so I thought that settings are saved properly.

However, after rebooting my system... I saw resolution 1024x768. I've tried to reinstall gnome-control-center, but it doesn't help - each time when I reboot, I need to manually go to 'Displays' and set resolution back.

  • I've tried to add xrandr commands to startup programs, but it seems that my screen misbehaves - I see black background.

  • This idea (to use xrandr as startup process) is also mentioned here, but it seems that it works only after booting Gnome - otherwise screen is stretched or misbehaves.

Is there any solution to save mentioned settings 'by hard' (is it a bug in Gnome?).
