My response might have completely no sense, but you might test: xrandr I recall, it helped me some time ago in similar issues.
You might want to use "gnome-control-center" too, to modify resolutions, screen setup (even, when using wmaker) This is my configuration that might not help you at all, but see this an example: Leave only laptop screen: xrandr --output DP1 --off xrandr --output DP2 --off xrandr --output eDP1 --mode 1920x1080 Clone laptop to external monitor: xrandr --output DP1 --mode 1920x1080 --same-as eDP1 Tomasz On Wed, Jul 13, 2016 at 3:58 PM, DING Yu <felixd...@gmail.com> wrote: > Hi, > > After I changed the resolution from 1024x768 (default) to 1920x1200 (my > monitor), the Dock stills is in the original position.
