Ubuntu 16.04 Resolution stuck at 1024 x 768

Question

I tried the posts in Screen resolution stuck at 1024x768 but they didn't seem to help.

In my display settings, I am unable to see any other resolution besides 1024 x 768.

The output of xrandr is

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 1024x768+0+0 0mm x 0mm
   1024x768      76.00*

and the output for 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

        v: height 1024 start 1027 end 1034 total 1063           clock  59.89Hz

I am connected via a display port cable. Could someone please assist?
