Public bug reported:
I was happily using 14.04 with my Lenovo Y50. When I installed it, I had
some troubles making my NVIDIA GeForce GTX 860M 2GB works with hardware
acceleration, etc, but at the end everything was OK.
THIS WEEK (around 02/25/2015) an update destroyed this beautiful
equilibrium: I can't resume after suspend and I can't plug or unplug my
external monitor without having a weird problem:
a) Desktop "moves" half of it size to the right.
b) Mouse works, but I can't click on anything. The only workaround is
killing the Xorg, and loosing the session.
What I tried, without success:
1) Downgrade Compiz (the first suspect, it was upgraded this week).
Nothing.
2) Install ALL possible NVIDIA drivers:
2.a) Nouveau
2.b) Nvidia 304 & Nvidia 304 updates (blacklisting and purging nouveau)
2.c) Nvidia 331 & Nvidia 331 updates (both from repository and NVidea
website). (blacklisting and purging nouveau)
2.d) Nvidia 340 (from Xorg-edgers ppa). (blacklisting and purging
nouveau)
2.e) In every case, I purged previous drivers before, reconfigure Xorg,
etc, etc,etc.
3) Reinstalling Unity and Ubuntu-desktop
I honestly don't know what else to do, but this situation it's very
annoying.
Any ideas? Please?
THANK YOU
