I have the same problem. Ubuntu 11.04 64bit, clean installed, fully updated. Linux media 2.6.38-11-generic #48-Ubuntu SMP Fri Jul 29 19:02:55 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux . I have configured auto-login at unity on boot.
Some times (not always but quite frequently) upon bootup, screen flickers in a rate once in about 10sec, while screen contents are partially rendered with various artifacts and distortions. Mouse and keyboard have very slow or no responsiveness. Pressing ctrl+alt+F1 repeatedly until I manage to get to the text console, and then loggin in and runnig sudo /etc/init.d/gdm restart solves the problem. My VGA is 01:00.0 VGA compatible controller: ATI Technologies Inc RV710 [Radeon HD 4350] and X use the opensource RADEON driver. ** Attachment added: "kern.log part from boot to gdm restart" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/728923/+attachment/2411503/+files/kern.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/728923 Title: [Natty] WARNING: at /build/buildd/linux-2.6.38/drivers/gpu/drm/radeon/radeon_fence.c:248 radeon_fence_wait+0x36f/0x3e0 [radeon]() To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/728923/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
