[Hardy] gnome-display-properties does crazy things

Please attach your /var/log/Xorg.0.log and the output of `lspci -vvnn` and `xrandr`. This is an xrandr issue rather than gnome-display-properties. It sort of sounds like it's looking at the available resolutions from each display and selecting the lowest common denominator.

Hard to say what the issue is, without the Xorg.0.log, so unassigning myself until the bug is further triaged.

Many of these strange behaviours are not reproducible. Today I just wanted to disable the notebook display and enable the external one with its native resolution. Look at the screenshot to see what I got after I pressed the apply button.

Sounds like it just needs the tv-quirk. Please attach the output of lscpi -vvnn and xrandr.

(II) intel(0): Output VGA disconnected
(II) intel(0): Output LVDS connected
(II) intel(0): Output TMDS-1 connected
(II) intel(0): Output TV disconnected
(II) intel(0): Output LVDS using initial mode 1440x900
(II) intel(0): Output TMDS-1 using initial mode 1280x1024

You could also try running 'xrandr --output TMDS-1 --disable' prior to using the tool, and see if that gives better results.

In any case, this is clearly not a gnome-control-center bug. Reassigning package.

This also does not happen every time. I currently work with the external display with correct settings. I think it mainly happens when I disable the notebook display AND enable the external display with its native resolution on the same time.

Yep, the TV out is turned on, thus causing this problem, so just needs the quirk. Here is a deb to test.

http://people.ubuntu.com/~bryce/Uploads/xserver-xorg-video-intel_2.2.1-1ubuntu7_i386.deb
http://people.ubuntu.com/~bryce/Uploads/xserver-xorg-video-intel_2.2.1-1ubuntu7.dsc

Does this package work on a 64 bit install? BTW: My notebook has no TV out. So why is it turned on?

No, 32 bit only. The .dsc is there at http://people.ubuntu.com/~bryce/Uploads/ if you'd like to build it yourself via ppa or whatever. We'll include this in a future upload.

As I understand it, the underlying chipset includes tv out, but the board manufacturer may or may not hook it up to an actual output connector, and unfortunately there is no way the driver can detect on its own if the connector is hooked up or not. Apparently it also cannot detect if there is something hooked to the connector or not, like it can with VGA/DVI. So upstream takes the approach of quirking each card discovered to have this problem.

This bug was fixed in the package xserver-xorg-video-intel - 2:2.2.1-1ubuntu7

---------------
xserver-xorg-video-intel (2:2.2.1-1ubuntu7) hardy; urgency=low

  * debian/patches/12_quirk_sync.patch: Add some quirks from current git
    upstream, and a quirk for Dell Latitude D630 (LP: #197740)
