I had this issue on a Acer Aspire 5750G. Today I updated my system with the latest NVIDIA driver 343 from the xorg-edgers repository. Because Ubuntu would not let me login (black screen after entering password in lightdm) after the update and command line switching did also not work I reset compiz and unity by following the instructions here (Fix 1 to 6): http://askubuntu.com/questions/449845/problems-after-upgrading-to-14-04-only-background-and-pointer-after-login
After I was able to use the newest driver I wasn't able to reproduce the bug after at least 2 hours of testing. Before the update the issue occured very frequently.
Hi All,
I had this issue on a Acer Aspire 5750G. Today I updated my system with the latest NVIDIA driver 343 from the xorg-edgers repository. Because Ubuntu would not let me login (black screen after entering password in lightdm) after the update and command line switching did also not work I reset compiz and unity by following the instructions here (Fix 1 to 6): http:// askubuntu. com/questions/ 449845/ problems- after-upgrading -to-14- 04-only- background- and-pointer- after-login
After I was able to use the newest driver I wasn't able to reproduce the bug after at least 2 hours of testing. Before the update the issue occured very frequently.
I will report if the bug reappears.
