Description Christoph 2009-11-28 04:51:29 UTC
I have a laptop with X1350 and an external SyncMaster T240 with 1920x1200 connected via DVI.
Using the proposed standard xorg.conf from http://www.x.org/wiki/radeonhd all monitors are black, no response or restart of X server possible.
When I delete xorg.conf, the X server starts both monitors work with the execption that the external cannot be switched to its native resolution and the "radeon" (kernel?) driver is loaded.

(EE) RADEONHD(0): RHDMCSetupFBLocation: Cannot setup MC: not idle!!!

Standard issue, which unfortunately isn't fixed yet. AFAIR radeon doesn't test for MC idle, dunno whether you can have issues from that or not.

MC lockup issue.
Comment 4 Jeremy Huddleston Sequoia 2011-10-16 15:57:42 UTC
Does this issue occur with the preferred ati driver (xf86-vide-ati)?  If so, please move this to the Driver/Radeon component.  

Development of radeonhd has pretty much halted and development focus is on the ati driver.  Please see http://www.x.org/wiki/radeonhd

If the issue does not exist in the ati driver (or if there is no response to this message), this bug will be closed as WONTFIX unless someone contributes a patch.
Comment 5 Jeremy Huddleston Sequoia 2011-11-07 15:40:15 UTC
Closing due to lack of response.  Please reopen and move to the Driver/Radeon 
component if this issue persists with xf86-video-ati
