An extra comment: the many crashes that I mentioned in my initial report have gone away after I replaced my memory modules.
This problem however has not ceased to exist and every once or twice a week I get no monitor input (at all) on startup of X (boot menu shows up fine) and need to reboot the computer. After rebooting my apport tells me that Xorg had crashed, which is this bug. -- Xorg assert failure: *** glibc detected *** /usr/bin/X: double free or corruption (fasttop): 0x092447a8 *** https://bugs.launchpad.net/bugs/501551 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. _______________________________________________ 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
