Description Elmar Stellnberger 2009-10-13 10:44:28 UTC 
As soon as I try to run a 3D-app as Neverball or Google Earth with the radeon-driver my whole system totally hangs; my machine becomes irresponsive to keystrokes (even to ctrl-atl-del) although the mouse can still be moved; nonetheless all running apps do not respond to mouse events any more; turning the power off is the only way out.

Do you use kernel modesetting? If so, have a look at bug #24218
Comment 2 Elmar Stellnberger 2009-10-13 11:03:36 UTC 
How can I determine whether my kernel uses modesetting?
Comment 3 Alex Deucher 2009-10-13 11:09:45 UTC 
Please specify what GPU you are using and attach your xorg log and config.

Comment 6 Elmar Stellnberger 2009-10-13 11:24:53 UTC 
Is there any way to disable kernel modesetting by a kernel parameter?
Comment 7 Marcin Baczyński 2009-10-13 11:31:05 UTC 
Add radeon.modeset=0 to kernel cmdline

Xorg.3.log: no hangs with radeon.modeset=0

  On usage of the radeon.modeset=0 kernel parameter things in deed work fine. The only drawback is that thereby Bug 24440 occurs again (integrated screen unusable).
Comment 10 Alex Deucher 2010-10-19 18:36:54 UTC 
Is this still an issue with a newer kernel, ddx or mesa version?
Comment 11 almos 2012-12-28 20:41:41 UTC 
Is this still an issue?
Comment 12 Elmar Stellnberger 2013-02-11 15:28:02 UTC 
This has been resolved by the radeon display driver distributed with openSUSE 12.3 RC1, kernel 3.7.6-1.2-desktop. 3D apps do start and work now however with a somehow significantly lower performance than the OEM drivers; but good work having got all of it to at least work;: tested neverball and etracer.
