Xorg.0.log

xf86-video-ati, master (d586a2c6f821c821a4a7708a3382acb63187534f)
Ubuntu 8.10, xserver-xorg 1:7.4~5ubuntu3

Warning, I think this may be a duplicate of bug 20146 but that is against radeonhd.

My computer have an onboard HD3200, and a pci-e HD3870:

$ lspci|grep VGA
01:05.0 VGA compatible controller: ATI Technologies Inc Radeon HD 3200 Graphics
02:00.0 VGA compatible controller: ATI Technologies Inc Radeon HD 3870

The radeon driver only work with the card that is set as primary display in BIOS. If I try to use the secondary card I get an X server process that uses 100% CPU, blank monitors and killing X does not restore the VT.

The attached log files is with the HD3870 set as primary display in BIOS, but BusID "PCI:1:5:0" (HD3200) specified in xorg.conf. Looking at the "BIOS Bootup Message" it tries to use the BIOS for the primary RV670 instead of the RS780.


Thank you for working on the r6xx-r7xx support! :-)

Only KMS is able to get the vbios for the rs780 when it's not the primary.
