Public bug reported:
My setup: Dell M4600 laptop with Dell U3011 2560x1600 monitor attached
to DisplayPort.
I was using Nvidia 331.38 prioprietary driver for quite a long time with
Ubuntu 14.04 LTS and everything worked perfectly. Today I upgraded to
Ubuntu 14.10, which comes with Nvidia 331.89 and observed the following
problem:
1. When I boot up the computer with the monitor connected, the login
screen looks fine. Both displays get detected properly and resolutions
are ok (1920x1080 on the builtin laptop display and 2560x1600 on U3011)
and screen contents scaled properly.
2. Then I log into my account, for 3 seconds U3011 displays some rubbish
(but it was always like that) and when it finally logs in, it displays
everything stretched horizontally through both my screens. It looks as
if it tried to paint the contents of a single display on two of them, by
stretching the content horizontally, so everything (icons, windows,
wallpaper) has wrong aspect-ratio. Funny, the top status bar seem to
render correctly. Physical resolution of both screens is ok. I'll attach
a photo, because it is hard to describe how it looks.
3. I cannot use system in this state - mouse click position seems to not
be synchronized with what's on the display - e.g. I can start
applications, but then they don't react to mouseclicks.
However: booting up without the second display connected, logging in and
*then* connecting the second display works fine.
I tried deleting ~/.compiz and ~/.config/compiz-1 directories but the problem
remains.
I also tried to go into the Displays configuration when everything is ok, apply
the settings there (without any changes) in hope it will persist them somehow,
but after restart it is broken again.
I also tried reinstalling nvidia 331.89 drivers, because it complained
about not being able to install nvidia-uvm during the upgrade process
(reported separately), and now all nvidia packages installed cleanly.
Before that I also got rid of all the ppa mainline kernels I had, just
in case they mess something up.
I remember the same problem happened on Ubuntu 14.04 when I tried to
upgrade nvidia from ppa/xorg-edgers to 331.89, but then the easy
workaround was to downgrade back to official 331.38. Now I have no
choice :(
