View Full Version : [ubuntu] Green vertical lines on screen after switching sessions

Hi all,

When I switch users and I get back to a previous session, my screen is striped with green vertical lines. It tried changing the screen resolution but it only changed the lines shape.

It happens with 2 different users, depending on which one starts a session first. They appears when switching back to the first session, and there is no lines when I get back to the second session.

It seems like it doesn't load something properly when switching back. I don't know if it could be related but I am using Metacity that already made me experience some issues affecting other applications.

Probably worth to mention, I am not sure if it is related but I sometimes get a black screen forcing me to reboot after a session has been locked.

I've asked Google but I couldn't find any related issues. People who got these lines where having driver issues but everything works fine for me until I start switching sessions.

Any advices?

Thanks

Have you found a solution to this problem?

I think it would be worth to report as a bug if there is no work around.
