    External monitor will only mirror

    I'm using kuki (with Xfce) on an EeePC 1004 HA, dual-boot with XP. I have a Mitsubishi RDT1785 monitor attached. In XP I can set it as an extension of my desktop at a different resolution than the netbook, but not in Linux.

    Part of the problem is most likely the fact that when I open Settings > Display, only Screen 1 appears and there is no Detect button which I gather should be there.

    Any suggestions of how to get the external monitor working properly. (For me, properly will be as an extension to my netbook screen but at the higher resolution recommended for that monitor -- 1280 x 1024 rather than the 800 x 600 setting for the netbook.)

    Thanks in advance for any help you can give me. I'm new here in LinuxWorld and feeing a bit lost.

    Mirror external monitor with different resolution

    I have exactly the same problem. Why isn't it possible to mirror two screens (in my case the one on my Acer Aspire Timeline 1810TZ and my external 24" BenQ widescreen) with two individual resolutions? Please help!

    Re: External monitor will only mirror

    Mirroring would be dependent on your device drive. Are you using a proprietary video driver? Is there one available?

    How can I check what driver I have and if it is "proprietary" or not?

    I'm not familiar with xfce, someone else will have to chime in.
    In gnome it's under System -> Preferences

    by default, no propriety driver is installed - unless you install it yourself, or if you tell ubuntu to install it for you.

    run this in the terminal then attach the lspci.txt and the xorg.conf (their right on your desktop)
    Code:
    lspci >> ~/Desktop/lspci.txt
    cat /etc/X11/xorg.conf ~/Desktop/xorg.conf
    Don't waste your energy trying to change opinions ... Do your thing, and don't care if they like it.

    Thank you very much Cary. Your advice looks very promising. There is only one slight problem. I don't see anything resembling lspci.txt or xorg.conf on my Desktop.

    cat /etc/X11/xorg.conf ~/Desktop/xorg.conf

    I see!

    I ran the first in Terminal and lspci.txt appeared on my desktop, but not xorg.conf

    I tried running lspci.txt in Terminal but got a whole bunch of this:
    bash: syntax error near unexpected token `('


    Is that what I was supposed to do with lspci.txt?????

    Typo

    cat /etc/X11/xorg.conf >> ~/Desktop/xorg.conf

    Then attach both those files to your next post so we can look at them.
