xorg.log for the 4350

On three different radeon cards (x1600, x600 and hd350), a dvi output claims to be disconnected when a monitor is attached. Changing the monitor does not affect this. On X start, the monitors are enabled in mirror-mode (Alex Deuchar has suggested that this is possibly the bios leaving the output on using the same CRTC).

xrandr shows the DVI output to be disconnected.

The driver in use is git commit 14aff767490c253cbcdd411f812e50b91673119e on OpenBSD current.

attached are Xorg.logs and configuration files for the cards in question. Xrandr output on the hd4350 follows:

$ xrandr
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 3280 x 1200
VGA-0 connected 1280x1024+0+0 (normal left inverted right x axis y
axis) 376mm x 301mm
   1280x1024      60.0*+   75.0     72.0     60.0*
   1152x864       75.0
   1024x768       75.0     70.1     60.0
   832x624        74.6
   800x600        72.2     75.0     60.3
   640x480        75.0     72.8     66.7     59.9
   720x400        70.1
   640x350        70.1
HDMI-0 disconnected (normal left inverted right x axis y axis)
DVI-0 disconnected (normal left inverted right x axis y axis)
$ xrandr --output DVI-0 --auto --right-of VGA-0

the final command caused flickering but no other change.

Sorry. I hit enter before I finished typing the description.

By changing the monitor, switching the two identical monitors (one on vga, one on dvi) was meant.

Sorry for the delay, but No Alex, it doesnt' help The patch appears to
make no difference to the
behavior.

Bob informs that the kvm switch he was using was the source of the bug.

Removing the kvm makes all cards work correctly with the git driver, marking as NOTABUG.
Comment 9 Bob Beck 2010-03-29 08:24:22 UTC
My apologies, the stupid kvm never got in the way before.
