I know I know, there are tons of questions regarding unrecognized screen resolutions, using xrandr, installing Nvidia drivers and related.
My new system is running Kubuntu 16.04, with kernel version 4.4.0-generic. It is a custom built computer, running an external video card, EVGA 1060 GTX 3GB model.
Following advices in this "guide": How do I install the Nvidia drivers? I was able to install the latest nvidia-370.
Now, on the ASUS monitor I am currently at (ASUS VS247H), the resolution should be 1920x1080, but only a maximum of 1024x768 is shown if running xrandr -q
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768
default connected primary 1024x768+0+0 0mm x 0mm
1024x768 76.00*
Things I tried so far:
1)-------------------------------
The first thing that bothered me from the above was the line
xrandr: Failed to get size of gamma for output default
I tried some things, for example the first answer of this question here: "Fails to get size of gamma" error when trying to set resolution, which did not have any effect.
Then I realized that I had no file under /etc/X11/xorg.conf did not exist, and yet another answer at the site popped up: /etc/X11/xorg.conf doesn't exist?
Fazit: I tried generating my own as described in the first answer of this question: Where is the X.org config file? How do I configure X there? and then manually set a Screen with the correct resolution, without success.
2)-------------------------------
As mentioned in this guide about xrandr, I tried using
cvt 1920 1080 60
xrandr --newmode <output of the above>
xrandr --addmode HDMI1 1920x1080_60.00
But still, the above
xrandr: Failed to get size of gamma for output default
seems to be killing me.
