Rats. I loaded synaptic and chose to remove nvidia 270 and install 173 and had all kinds of problems.
When I rebooted, the loging screen was only one thin line of display at the top of the monitor and all the rest was black. I could reboot with default display from the recovery mode, and used the additional driver tool to go back to nvidia-current and the blank windows are back. If I open the firefox windows the third one is blank. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/752445 Title: Intermittent white window contents when maximizing/switching windows -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
