Title: Screen resolution no longer works Status in linux package in Ubuntu: Incomplete Bug description: My display's native resolution is 2560×1440 pixels. Prior to, I think, Saucy I could only reach this resolution by adding it using xrandr, and then calling xrandr on boot/login to select that resolution. The Display preferences did not show any higher options than 1920×1200. In Saucy, the native resolution just worked, and I could stop using xrandr. It also worked in Trusty in the alpha releases, up to (and I think including) beta-1. But today (this is not an April's fool, is it?) I rebooted after an upgrade, and found myself back in 1920×1200. Again, the Display preferences list that resolution as the highest possible. But this time, attempts to ‘xrandr --addmode’ my native resolution failed. The error message wasn't very helpful; I'll try to reproduce it later but it throws my display into yet a lower resolution that's hard to work with.
