    Default openSUSE 11.0 Dual Desktop problems with KDE 3 and 4

    Just install openSUSE 11.0 on my computer at work. I have been using dual desktop, not Xinerama or TwinView, since openSUSE10.0. I prefer dual desktop over a single with Xinerama or TwinView. Here are the problems I am having.

    Card Nvidia GeForce 6800 GT AGP
    Left Screen is screen 0
    Right Screen is screen 1
    Both Screens were configured to have 6 desktops

    KDE 4
    Found no problem with the Left Screen.
    The Right Screen had no configuration it was completely black. When the mouse was moved to it there was a X for the pointer and right and left clicks did nothing.

    KDE 3
    Found no problem with the Left Screen.
    The Right Screen came up, but only showed one desktop instead of six. Went to configure the desktop to set Multiple Desktop back to 6. The Personal Settings started with no boarder or title bar. Change number of desktops to six and hit apply. There was no change in the desk top. Tried to get a screen shot with KSnapshot, but every time I pressed Print Screen KSnapshot started on the left desktop.

    Logged in as both a user and root and got the same problems. Boot back to 10.3 to get a working desk top, had to restore my desktop for 10.3 because KDE problems in 11 were now saved in my right desktop.

    Is anyone else haveing problems like this in openSUSE 11.0? Thanks.

    Note: xorg.conf was copied from 10.3.

    Just wondering (maybe incorrectly) if this is a window manager issue. Which window manager are you using? I know KWin was substantially upgraded for KDE4. Other users have reported similar problems with secondary displays.

    As a matter of interest, what advantages did your dual desktop configuration provide over Xinerama? Did you need each display to have multiple desktops available? Maybe if you post your xorg.conf file, someone can help.

    BTW, can Xorg Randr be of help here?

    Thanks for the reply. In my case dual desktop is what I prefer. However, we build flight simulators that are using multiple desktops up to 7 displays including a console.

    /etc/sysconfig/displaymanager
    ...
    DISPLAYMANAGER="kdm3"

    Default Re: openSUSE 11.0 Dual Desktop problems with KDE 3 and 4

    I know that there have been graphical and functional issues for KDE with Compiz and KWin (KDE4). This of course can be set via KMenu > Control Centre > KDE Components > Session Manager

    An interesting experiment would be to see how other desktop environments behave. Wish I could assist more, but this problem is over 8' tall to me

    As this is almost certainly not specific to openSUSE, I'd suggest posting this at Main Page - KDE-Forum.org

    I do not have a specific answer for you, but I can post a working xorg.conf from 11.1 32bit and 11.2 64 bit that I use currently. It will not be a drop in solution because your setup will be different than mine. My main monitor is a 22" Samsung LCD and my old 17" CRT sits off to the right side. Remember: just use for example purposes. YMMV

    Thanks for the reply. I searched google again, there are new threads in KDS's forum from this year. KDE 4 does not support dual desk top. My problem is not with X but with KDE.

    What do you mean by "dual desktop". Are you certain the problem is with KDE ? (and not a graphic driver). Please note I am able to display my KDE4.3.2 on two different displays (one laptop, one a projector): Laptop External Monitor Support - openSUSE Forums

    I take it then, this is not what you have in mind..... and it also does not provide a work around solution ?

    Dual Desktop or Multi Head is where there is a different X server runing on each display. Each monitor get is own start menu and task bar.
