I had the same problem on ATI Radeon 9200 PRO. Disable Option EnablePageFlip in Device Section in /etc/X11/xorg.conf fix it. It should looks like this
Section "Device" Identifier "Device0" Driver "radeon" Option "EnablePageFlip" "off" EndSection Or just comment out or remove the line, becose disable is the default value for radeon driver. -- Stelaium crashes on startup due to fragmentation fault https://bugs.launchpad.net/bugs/481669 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
