After upgrading to 8GB RAM i got the same error (0) and X segfaulted. According to (1) i switched off the dual channel mode and the problem disappeared.
So i think this is not - as assumed above - a HW failure but a problem of the nvidia module which is confused by large RAM in dualchannel mode. -- (0) NVRM: Xid (0000:03:00): 6, PE0001 (1) https://bbs.archlinux.de/viewtopic.php?id=18836 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/717873 Title: NVIDIA X driver causes flickering To manage notifications about this bug go to: https://bugs.launchpad.net/nvidia-drivers-ubuntu/+bug/717873/+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
