Description Vedran Miletić 2008-08-03 09:38:15 UTC 
I have a Biostar TA780G M2+. When X loads, I get nothing on DVI output, even the driver detects presence of it.

VGA output works normally.

I have built git radeon driver, but it didn't help.

Please try again with ati from git master.  I've significantly reworked the output setup.

I have the same problem with asrock A780FullDisplayPort and radeon driver version 6.12.2. No output on DVI, VGA works.

DVI works with the same setup and radeonhd 1.2.5
Comment 6 Alex Deucher 2009-04-23 12:31:32 UTC 
Can you both try ati git master?  If this is pll related, I recently added support for fractional feedback dividers which should help hit closer to the desired dot clock.
Comment 7 Christian Preilowski 2009-04-26 10:24:32 UTC 
Just tried ati from git master but without success. DVI is still not working.
Comment 8 Alex Deucher 2009-10-21 13:46:32 UTC 
can you try with ati from git master?  Specifically commit 66b194a78c470cb3978f310828dd96c3f3e96944.
Comment 9 Alex Deucher 2009-12-09 10:07:34 UTC 
Can you try with the latest code from xf86-video-ati git master?  I just committed some new PLL code that might help.

Tried version 6.12.4 today. DVI is now working for me :-).
