Bug 218716

Version:            (using KDE 4.3.4)
OS:                Linux
Installed from:    Debian testing/unstable Packages

Hi,

my notebook has a Mobility Radeon 9600 M10 which I use with the open source radeon driver. The internal panel has 1400x1050, the external monitors which I usually use (one analog at home, one digital at work) both have 1600x1200 pixels. In both setups the external monitor is left of the internal panel, and thus screen 0 has a resolution of 3000x1200 with the lower right 1400x150 pixels not being visible. My main KDE panel is at the lower edge of the external display.

When I disconnect the external monitor and use xrandr to reconfigure the internal panel to be at pos 0x0, the main KDE panel does not display any more. It doesn't even display any more when I manually move the panel from the external display to upper edge of either display. It just doesn't show when there is no external display connected.

The panel used to behave correctly (showing on the internal display when the notebook is operated standalone, and on the external display when there is one connected) in KDE 3, and even in KDE 4.3.2 when I updated from KDE 3. The wrong behavior has started spontaneously after a week of not doing any updates, and has continued to show through all updates I did, including to KDE 4.3.4 which I am using right now. I am not aware of having done any changes to my KDE configuration which could have caused this issue.

Is there anything I can do to work around this issue or to help debugging it?

Greetings
Marc
