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 Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
