[Bug 1300557] Re: Screen resolution no longer works
Jeroen T. Vermeulen, could you please test the latest upstream kernel
available from the very top line at the top of the page (the release
names are irrelevant for testing, and please do not test the daily
folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will
allow additional upstream developers to examine the issue.
If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-3.XY-rcZ
Where XY and Z are numbers corresponding to the kernel version.
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-3.XY-rcZ
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results.
Thank you for your understanding.

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.
