    Default 11.2 and dual monitors

    Have successfully installed 11.2 on another laptop with dual displays. I have, however a problem: I need to alter the resolution of the external monitor to its default of 1680 x 1050 every time I log in, otherwise it uses the laptop default on both screens.

    How do I ensure that it retains the settings I enter?

    I'm using KDE 4.3 on a 64-bit installation of 11.2.

    DO you know what driver / chipset you are using. I think the answer may be different for nVidia and other drivers

    It's an ATI Radeon HD3200. More than that, I don't know. If you need other info, can you give me "Janet and John" instructions?

    Hmm - I'm no expert on ATI hardware.
    The likely solution will be to use xrandr : there are clear instructions here:
    Simple dual monitor setup with XrandR in Ubuntu (Linux) - Navetz
    although that is obviously for Ubuntu I have followed them without difficulty for previous SUSE installs.
    Let me know if that helps.

    If running Gnome, and you look at the task-bar at the bottom of the screen, you'll see an icon with a monitor and a triangle ruler over it, clicking this will allow you to set display settings.

    The original message was about KDE4.3, and I have not managed to get dual monitors set up properly using the KDE native tools. I must admit, though, that it has to be worth trying System Settings/Display first - I has assumed aescott had alredy tried that, but maybe not?

    I don't know about 11.2, as I have read some stories that the proprietary ATI driver is difficult to install.

    Still, for 11.1 on a 64-bit install with KDE-4.3.2 on a ATI Radeon 3450HD here is my experience (starting in post#11):
    Laptop External Monitor Support - openSUSE Forums

    I note if one wanted one probably could create a custom xrandr command (to configure an external display at the correct resolution) and put that in small script that is launched from an icon on the desktop.

    Yeah, I have tried that. It's a strange one, because when I use the System Settings / Display, I can make the necessary changes; however, the native resolution of my external monitor seems wrong. When I accept the "auto" (1680 x 1050), the edges of the screen disappear i.e. when I maximise an application, its edges disappear off the edge of the screen. They are fine if I move back to the laptop display.

    Irrespective of this, when I restart, my settings are not retained - I go back to a cloned display with the same resolution on each screen. I know that it is not the card - I had Fedora 11 installed before and it worked perfectly. I am thinking of returning to Fedora for my home laptop and keep openSUSE for my work one, hopefully giving me the best of both worlds. (Notice that Windows doesn't figure there - I have to use it, but I don't have to like it!)

    My guess is by some means, you managed to create an xorg.conf file in Fedora that provided you with the capability that you want. If you do go back to Fedora, keep that xorg.conf file, and then if you then return to openSUSE, you may be able to use some of the contents of that file to create an openSUSE equivalent.

    Fedora created the xorg automatically - I didn't need to do anything. As I said, I can have both systeme without any problem, so that seems to be the ideal solution...for now!

    Thanks for the help and suggestions.
