I'm having video driver problems with all the newest distros. If I use nvidia-current I get random black application windows when I already have a window open. For instance, I have a Libre Office document open and all is fine. Then I open a Firefox window and everything except the title bar is black. This has happened in the newest Narly Nachos, Mepis, and Sabayon. In Narly Nachos the problem went away when I activated nvidia173.
In PCLOS I'm trying to use kwin effects and nouveau is extremely slow so I thought I'd try the previous nvidia driver to see if that fixed the black screens but I can't figure out how to activate it. Three nvidia drivers were installed during the installation (PCLOS 2011.6, KDE). I deleted the current and 96 versions and re-installed 173 but when I go to PCC > Hardware > Configure Video Card and choose my card, nvidia 6100 or greater, it doesn't offer to activate the driver.
My card is an onboard nvidia 6150 se.
How can I activate the nvidia 173 driver so I can gets me some wobbly windows?
p.s. Narly Nachos? Too cute.
