My first post:
I have tiny problem when i either logout or switch user i get to blac/nk screen. Ctrl+Alt+Bckspce just gets my pc to either halt w/ no keyboard to work (reset button is only solution) or gets get back to blac/nk screen.
2 users on same pc means it's really annoying problem.

2 users on Kubuntu Gutsy w/ Ati 2400hd, Msi Neo-F2 and 2gb ram. No compiz or other effects. Fglrx 8.42. 8.41 was like swimming in upstream in tar aka it was useless.

Anyone else w/ similar problem(...specially in x/k/ubuntu users)??
