Hi, I am running Debian stretch on a Dell Latitude E7470.
This is my output from xrandr, I expected to get information about what outputs are available. My laptop is connected to another screen (also Dell) though a docking station (HDMI). hedkam@hopper:~$ xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080 default connected 1920x1080+0+0 0mm x 0mm 1920x1080 0.00* My guess so far is that it is a driver problem!? What would you suggest is my next move? Best, Hedda
