Bug Description

Binary package hint: xserver-xorg-video-ati

Hi there,

This appears to be a regression in the latest hardy. All was working well, I upgraded (~400 packages). My monitor's maximal resolution is 1680x1050, which I used. Post-upgrade, it's now at 1280x768. Due to an unrelated[?] problem, I can't even open gnome-display-properties to change it, but querying xrandr gives this:

Screen 0: minimum 320 x 200, current 1280 x 768, maximum 1280 x 1200
VGA-0 disconnected 1280x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
DVI-0 disconnected (normal left inverted right x axis y axis)
S-video disconnected (normal left inverted right x axis y axis)
  1280x768 (0x50) 80.1MHz
        h: width 1280 start 1344 end 1480 total 1680 skew 0 clock 47.7KHz
        v: height 768 start 769 end 772 total 795 clock 60.0Hz

The monitor is attached by DVI. xrandr says otherwise, which is curious.

01:00.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200] (rev 01)
01:00.1 Display controller: ATI Technologies Inc RV280 [Radeon 9200] (Secondary) (rev 01)

Attaching X logs. It appears confused about the (non-)presence of the output devices.

Attaching `sudo get-edid`. It fails, in the end.

I think your problem (translaterx_german) is quite different to mine. Please file a new bug.

I'm closing this one. Somehow it went away.

get-edid now works. xrandr returns the list of resolutions successfully, on the correct device:

Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 1680 x 1200
VGA-0 disconnected (normal left inverted right x axis y axis)

Symptom of bug mysteriously disappeared - the machine had been rebooted 10~20 times without change, but after the power went off while it was on, on the next boot things were fine.

Changed in xserver-xorg-video-ati:
status:	New → Invalid
