Description Chris Rankin 2008-09-16 12:02:25 UTC 
I am running celestia 1.5.1 configured as:

configure --sysconfdir=/etc --with-gnome

The application runs fine until I create a dialog box from the menu bar, at which point the X server stops responding. (The mouse cursor still moves, you can't click on anything and the cursor icon doesn't change any more.) A reboot is then required.

The machine is a dual P4 Xeon with 2 GB of RAM with a Radeon 9550, running Fedora 9.

Please try a current drm Git snapshot. There was a bug in the handling of many cliprects which could result in lockups.

The latest drm from git gives this warning (2.6.26.4 kernel):

WARNING: modpost: module drm.ko uses symbol 'init_mm' marked UNUSED

I thought the init_mm symbol had been deprecated?

Anyway - using these new kernel modules with my 2.6.26.4 kernel does indeed solve the "dialog box lockup" problem. However, the GPU then locked up during my "Earth to Titan" test. (Start at Earth, select Titan as a destination and press "G"), although bug #13258 does suggest that R300 vertex handling is completely borked so maybe that's no surprise.
