When HDMI-0 is ignored, DVI-0 disappears entirely
The radeon driver selects the HDMI-0 output instead of DVI-0 and I can't figure
out how to correct it! My video card (Asus EAH3650 512MB PCI-E) is connected
to my monitor via Dual-Link DVI.
This happens in Ubuntu Intrepid and Jaunty, and Fedora 10.
When in 1280x800 mode, the card's HDMI-0 displays on DVI connector just fine.
But when in 2560x1600 mode, presumably because of the dual link, it's
completely garbled.
bron...@eva-jaunty:~$ xrandr -q
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 2560 x 1600
HDMI-0 connected 1280x800+0+0 (normal left inverted right x axis y axis)
646mm x 406mm
2560x1600 59.9
1280x800 59.9*
DVI-0 disconnected (normal left inverted right x axis y axis)
How can I tell Radeon to ignore the HDMI-0 output and only use DVI-0?
I tried using the following xorg.conf:
Section "Device"
Identifier "Video Card"
Driver "radeon"
Option "Monitor-DVI-0" "Good DVI"
Option "Monitor-HDMI-0" "Bogus HDMI"
EndSection
Section "Monitor"
Identifier "Bogus HDMI"
Option "Ignore" "true"
EndSection
Section "Monitor"
Identifier "Good DVI"
Option "Enable" "true"
Modeline "2560x1600_60" 268.00 2560 2608 2640 2720 1600 1603
1609 1646 +hsync +vsync
Option "PreferredMode" "2560x1600_60"
EndSection
Section "Screen"
Identifier "Default Screen"
Device "Video Card"
EndSection
But, apparently when the HDMI output is ignored, the DVI output disappears
altogether! (see attached log file)
Is there any way to tell the radeon driver to use the DVI output?
