If you disable acceleration (add Option "NoAccel" "true" to the device section of your xorg config) do you still get the problems? It's most likely some issue related to the 3D engine set up in mesa. -- You are receiving this mail because: You are the assignee for the bug. --1391459391.dD4FEdf1.4841 Date: Mon, 3 Feb 2014 20:29:51 +0000 MIME-Version: 1.0 Content-Type: text/html; charset="UTF-8"

No.  disabling audio in the radeon driver just disables the audio stream in the
hdmi stream.  The audio device itself can't be disabled.

If you disable acceleration (add Option "NoAccel" "true" to the device section
of your xorg config) do you still get the problems?  It's most likely some
issue related to the 3D engine set up in mesa.
