I have confirmed this is not faulty hardware. I have used a similar video card with the same result. (That is I orginally reported with an ATI Radeon X1900 and thought it might be hardware so tried and ATI X1950).
Also, turning off all desktop effects stops the bug from occurring (probably because the drm module isn't being used much as a result). -- Lucid: system freezes randomly possibly due to bug on radeon drm module https://bugs.launchpad.net/bugs/567805 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
