I get the same thing using 270.30 and an nvidia 8600 card. It always seems to be is set off by some user-initiated action (eg last time it happened I had just clicked on the checkbox to turn windows previews on in compiz). It is certainly very annoying because you can't do anything until it decides to stop - and it can go on for more than 30 seconds.
There's a thread/bug report started about it at the nvidia forums http://www.nvnews.net/vbulletin/showthread.php?p=2414323 but nvidia don't seem to be very responsive to bug reports these days. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751047 Title: Screen flickers at random times with nvidia 270.30 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
