Description Frederic Crozat 2008-03-15 17:02:37 UTC

I've just upgrade my X.org stack 7.2 to 7.3 and display output became garbaged (screen unreadable but mouse cursor was correctly display), until I added     Option "DisplayPriority" "BIOS" (it wasn't needed with ati driver 6.6.3) to xorg.conf

Hardware :
* Card:ATI Radeon 9250 and earlier: ATI Technologies Inc|RV280 [Radeon 9200 SE] [DISPLAY_VGA] (vendor:1002 device:5964 subv:1787 subd:5964)
* Sony monitor SDM-X82 connected using DVI output

I'm attaching Xorg log when DisplayPriority is set and not set to BIOS.

I did a quick tarball bisection and regression got introduced between 6.6.3 and 6.6.191

Comment 4 Frederic Crozat 2008-03-24 04:39:36 UTC

Additional informations :

modeline is the same between 6.6.3 and 6.8.0, when displaypriority is set or not :

"1280x1024"   108.00   1280 1328 1440 1688   1024 1025 1028 1066 +hsync +vsync

I'm attaching output of radeontool regmatch '*' in the various cases

Is this still an issue with KMS or a newer version of the driver?

Comment 9 Frederic Crozat 2010-10-20 00:39:40 UTC

Unfortunately, I don't have this setup handy. Let's consider it fixed and I'll reopen if I can access the system where I had the issue.
