windows fail to respect panel boundaries with second screen 'above'

[Matthew Carroll]

Binary package hint: gdm

I am running a dual screens using Xinerama and the vga output from my laptop. When I have the second screen set to the right of my laptop's built in screen, as follows, maximised windows correctly respect the boundaries of any panels I have on either screen:

Section "ServerLayout"
...
Screen "Second Screen" RightOf "Default Screen"
...
EndSection

However, when I change this to:

Screen "Second Screen" Above "Default Screen"

...any panels at the joining edge of each screen (the top edge of 'Default Screen' and the bottom edge of 'Second Screen') fail to be respected by maximised / moved windows. maximised windows maximise to fill the space behind the panel, and moved windows do not experience the usual resistance effect when passing the panel boundary.

I have posted screenshots of the effect and my xorg.conf here:

Please email me if you need any more info, and accept my appologies if this is filed against the wrong package. I suspect it's gnome, but I'm really not sure what part deals with all that window behaviour.

Good luck
Matthew

Thanks for your bug report. Which version of Ubuntu do you use?

Hi Daniel

I was using Dapper when I reported the bug, now Edgy. I haven't had cause to use xinerama with one screen above the other for a while, so I forgot about this until now.

Unfortunately I cannot test whether the bug is still occurring in Edgy, since another bug in xinerama is preventing windows being moved between the two screens and maximized properly:

...once that is fixed I'll test this issue again.

Thanks
Matthew

Thanks for following up. I'm closing the bug for now. Please reopen if you have more information at hand.

I just did a fresh install of Feisty 20070415 (current RC candidate) - the Xinerama bug is fixed so I was able to test this behaviour again. The bug remains, exactly as described in the original report, therefore I am reopening.

Thanks
Matthew

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? May you try to reproduce this with a newer version of Ubuntu like Gutsy? Thanks in advance.

Closing this bug since no more information has been provided, feel free to re open it if you may give us the information we asked for. thanks.
