Here is a gdb session with the crash. Does any of this help me? Tormod, you'r a Ubuntu guy, right? Any idea why I'm getting a message about the r300_dri.so symbols report a CRC mismatch? I have applied the latest radeon drivers from /<a href="http://ppa.launchpad.net/xorg-edgers/drivers-only/ubuntu">ppa.launchpad.net/xorg-edgers/drivers-only/ubuntu</a>, other than that it's stock Kubuntu 10.4 install on an AMD64 that I loaded just yesterday. (Any chance any of these problems would go way If I went back to 32bit install?) If any of this info is useful, I can file a bug on launchpad. - Lowell ------------------------------- $ sudo gdb -p `pgrep X` GNU gdb (GDB) 7.1-ubuntu Copyright (C) 2010 Free Software Foundation, Inc.
