Comment 42 for bug 752445

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.
