Summary: HIS Radeon 9250CL 128 uses wrong DVI mode unless VGA is
connected
Product: xorg
Version: git
Platform: Other
URL: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=497209
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Driver/Radeon
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
QAContact: [EMAIL PROTECTED]
Reported by Felix Schueller on the Debian BTS last week, occurs with today's
xf86-video-ati git.
He has a "HIS Radeon 9250CL 128"
01:00.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200 PRO]
(rev 01)
When he boots with only DVI connected, the screen remains black. If he plugs a
VGA output, DVI will work fine. The difference seems to be that having VGA
plugged will make the selected mode on DVI switch from rate 60.0 to 59.9,
probably because the preferred mode for VGA uses rate 59.9.
If he boots with VGA plugged and then forces DVI rate to 60.0, the screen goes
black as well.
The log and output of xrandr when VGA is disconnect, not working then, are at:

When VGA is connected, xrandr says:

One thing we noticed is that S-video is wrongly detected as connected. We added
the necessary xorg.conf stuff to ignore it.
