Note that the second monitor in the hwinfo--monitor output is the internal monitor, not the 1280x1024 display which is connected via DVI.

Hmm. You have a laptop with 1x VGA + 2x HDMI outputs?

I have a docking station with 1x VGA and 2x DVI/HDMI/DP outputs. Only two can be active at the same time, obviously.

Thanks. I understand. We don't have any docking stations here though. Probably Intel developers haven't either.

I just verified: The problem also appears when only one the 1680x1050 panel is connected, and all others are switched off via xrandr or physically disconnected.

Please try with kernel boot option '915.powersave=0 '

Just did:

root@endlich:/home/micha> cat  /sys/module/i915/parameters/powersave                                        
0                                                                        

No change in behavior.

FWIW, the problem also exists under Fedora F13.

Update: The problem does not appear with 1280x1024 displays - it seems only 1680x1050 displays are affected. I can't test higher resolutions, though.

Possibly the monitor gives us a wrong modeline. You could try with standard modelines for 1680x1050.

# cvt -r 1680 1050
# 1680x1050 59.88 Hz (CVT 1.76MA-R) hsync: 64.67 kHz; pclk: 119.00 MHz
Modeline "1680x1050R"  119.00  1680 1728 1760 1840  1050 1053 1059 1080 +hsync -vsync

So try the folling:

# create new modes
xrandr --newmode "1680x1050+h+v"  119.00  1680 1728 1760 1840  1050 1053 1059 1080 +hsync +vsync
xrandr --newmode "1680x1050+h-v"  119.00  1680 1728 1760 1840  1050 1053 1059 1080 +hsync -vsync
xrandr --newmode "1680x1050-h+v"  119.00  1680 1728 1760 1840  1050 1053 1059 1080 -hsync +vsync
xrandr --newmode "1680x1050-h-v"  119.00  1680 1728 1760 1840  1050 1053 1059 1080 -hsync -vsync

# add modes to output
xrandr --addmode HDMI2 "1680x1050+h+v"
xrandr --addmode HDMI2 "1680x1050+h-v"
xrandr --addmode HDMI2 "1680x1050-h+v"
xrandr --addmode HDMI2 "1680x1050-h-v"

# switch between modes
xrandr --output HDMI2 --mode "1680x1050+h+v"
xrandr --output HDMI2 --mode "1680x1050+h-v"
xrandr --output HDMI2 --mode "1680x1050-h+v"
xrandr --output HDMI2 --mode "1680x1050-h-v"

Does any of these modes help? Then the EDID information of the monitor is broken.

:) Each one of the modes you suggested works; Thanks! :)

The question now is, can anything be done to fix this permanently? BTW, the monitor worked without issues with my previous notebook, which had an Ati mobility radeon x1300 graphics chip, with either fglrx, radeon and radeonhd drivers.

This information should be added to the quirks information of xorg-server
(hw/xfree86/modes/xf86EdidModes.c).

Most likely you still used a static xorg.conf with a 1680x1050 modeline generated by SaX2.

There is even already one quirk for your monitor in that code:

DDC_QUIRK_PREFER_LARGE_60
"Detailed timing is not preferred, use largest mode at 60Hz"

Maybe that's even the issue here ... possibly 

DDC_QUIRK_135_CLOCK_TOO_HIGH
"Recommended 135MHz pixel clock is too high"

helps here, but first I would like to see the output of

  xrandr --verbose

on a freshly started Xserver.

Created attachment 368961 [details]
output of xrandr --verbose on a freshly started xserver

Here's the output of xrandr --verbose from a freshly started xserver. I did an init 3 and subsequent init 5 on the console, I hop ethis counts for "freshly started xserver".

HDMI2 is the 1680x105 display (Samsung SyncMaster 225BW).

Thanks!

So that option wouldn't help, since only one modeline for this mode is available.

I'm afraid you need to live with a hack below /etc/X11/xorg.conf.d or report
that issue on bugs.freedesktop.org (product: xorg, component: Server/general).

Please add me to Cc (sndirsch@suse.de).

You'll need to register for an account on bugs.freedesktop.org
first, in case you don't have one yet. Thanks.

Well, I guess I can live with the workaround to set the custom modeline via xrandr. 

I filed a bug on freedesktop.org:

https://bugs.freedesktop.org/show_bug.cgi?id=28535

Thanks a lot for your help!
