I'm not sure if this is a bug, so i'm posting a question first so see if anyone can help me figure out it's a bug.
I just upgraded from 16.04 to 16.10 and now i'm missing a resolution mode on my XPS13-9350. I have 3200x1800 available, but i rather use 2560x1600, which was available to me while i was running 16.04.
I tried to mess a bit with xrandr, but the system froze while i was trying out stuff, so i'm not sure this is the right way.
Can anyone help me further?
