Public bug reported:
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 as the highest possible
resolution. But this time, attempts to ‘xrandr --admode’ 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.
