Having experimented with KDE plasma, I can say that KDE does not suffer the above screen corruption. KDE is also snappier and does not suffer from the sluggishness that appeared recently in classic Ubuntu.
The only problem I can see with KDE plasma is that when you play with the panel settings a black rectangle sometimes appears in the top left of the screen. This goes away when you finalise the panel settings. The conclusion I draw from this is that the problem might not be with xserver-xorg-video-nv (Ubuntu) per se, but was likely introduced when Unity was introduced (assuming that xserver-xorg-video-nv wasn't changed to accommodate Unity - I don't know how these things interact). -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nv in Ubuntu. https://bugs.launchpad.net/bugs/809396 Title: screen corruption on changing desktops To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nv/+bug/809396/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
