Thought I'd post this, just to get it into the archives for future searches by other users. With a Creator 3D on an Ultra Enterprise 2, with 2.2.20 and XFree86 4.1.0, I was receiving a Signal 10. The last messages from the server were the DRM messages. If you're having this problem, try commenting out the glx and dri modules from the XF86Config-4, or unselect them during package configuration. Thanks, Rob
