Public bug reported:
First of all, I am not sure whether this is a bug or not, but I tried
several times to set addmode (1920x1080) in xrandr. Never happened.
So, I simply tried creating a new mode using 10-monitor.conf and
restarted my system, it started showing blank screen.
I checked askubuntu forum and purged nvidia-*, after that it starting
showing me display but in 800x600 resolution. I tried adding 1920x1090
again but no luck.
The error while adding mode is `xrandr: Failed to get size of gamma for output
default`
and I am not using `sudo xrandr`, I am simply using this command `xrandr
--addmode default 1920x1080`
Kindly suggest the resolution.
Thanks
