Summary: via drm module ooopses (3D Application segfaults)
Product: DRI
Version: XOrg CVS
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM modules
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
I've got an issue with the via drm module. I'm running ubuntu Linux with the
xserver-xorg-video-via package. The 2D parts works ok, but when trying to run
3D applications, it fails.
I compiled the drm modules from drm cvs source and installed them over the
kernel modules. When the via module is installed I get this:
[ 48.930391] [drm] Initialized drm 1.1.0 20060810

Then - when I try to run a small Programm, which uses the glx Extension (read:
glxgears), the programm segfaults and I get this:
