    I can't set screen resolution above 800x600

    I have an eee 901 (with its tiny screen) and just bought a separate LCD screen. I tried to set the screen resolution with gnome-display-properties, but the maximum in the drop-down menu is 800x600 pixel. How can I change this?

    I checked the xorg.conf, but it is more or less empty.

    This is on 9.04

    Per.

    PS. My other 9.04 machines ("normal" size laptops) have a lot more alternatives for screen resolution.

    SOLVED: The trick is to uncheck "Mirror screens".

    The most common problem is that you don't have graphics drivers installed.
    You can try and go to 'System - Administration - Hardware Drivers' to see if there are any drivers available for you graphics card.
    So, you were talking about that... ummm... that... errr...
    Oh, yes, yes...

    by typing lspci in terminal, you can find the name of your graphics card.
    You should find a long output, but there will be something like this:
    01:00.0 VGA compatible controller: nVidia Corporation GeForce 9800 GT (rev a2)

    I guess you have Intels graphics card (EEEs use Intels I think).
    So, you were talking about that... ummm... that... errr...
    Oh, yes, yes...

    your best chance is to look up your model of laptop on the ASUS website and see what it says, it'll be under something like video chipset, or graphics processor, or some other combination of the two.

    I'm pretty sure (say 90%) that any atom processor only comes with specific intel components, so chances are you have one of the intel graphics processors. it'll be called something like intel GMA-something or other


    back in the day (read: 2006) I had some major problems getting my intel graphics card to display on an external screen in ubuntu. I doubt there's still issues with that, but as EEE's are relatively new and designed to be small I don't think there's been major effort put into making external monitors work perfectly, as in a higher resolution than the tiny screen can support.

    you may try searching other threads or forums to see if anybody has been able to get a monitor working at higher resolutions on an EEE.

    You may try these, but I did only in my compaq.

    Setting Compaq C700 series Screen Resolution to 1280x800 in Ubuntu 9.04
    Here's the procedures how to configure screen resolution.. do the update only if you have intel graphics else proceed to step 2.

    Step1:
    sudo apt-get update
    sudo apt-get install xserver-xorg-video-intel
    sudo reboot


    then backup and edit your xorg.conf by:

    Step2:
    sudo gedit /etc/X11/xorg.conf
    next save as xorg_backup.conf
    sudo gedit /etc/X11/xorg.conf


    upon opening the xorg.conf like this

    Section "Monitor"

    Identifier "Configured Monitor"

    EndSection



    Section "Screen"

    Identifier "Default Screen"

    Monitor "Configured Monitor"

    Device "Configured Video Device"

    SubSection "Display"

    Virtual 2048 779

    EndSubSection

    EndSection



    Section "Device"

    Identifier "Configured Video Device"

    EndSection



    then edit the xorg.conf like this:


    Section "Monitor"

    Identifier "Configured Monitor"

    EndSection



    Section "Screen"

    Identifier "Default Screen"

    Monitor "Configured Monitor"

    Device "Configured Video Device"

    SubSection "Display"

    Modes “1024x768” “1280x800”
    Virtual 2048 779

    EndSubSection

    EndSection



    Section "Device"

    Identifier "Configured Video Device"

    EndSection


    next click save and on terminal type the following:

    Step3:
    sudo dpkg-reconfigure -phigh xserver-xorg
    sudo reboot


    finally you got a widescreen resolution of 1280x800 in display preferences..

    ... but it did not work, I'm afraid! In fact, "dpkg-reconfigure -phigh xserver-xorg" destroys the xorg.conf edit, and resets it back t its default. I tried without dpkg-reconfigure but that turned my machine unusable; the system said it could not use my xorg.conf, and it had to reset it back to failsafe (default) state.

    Anyone else, that can help me out on this?

    I have it working now, but don't know exactly what I have done! I think that unchecking "Mirror screens" is the trick.

    My external monitor is an old Samsung Syncmaster 172b with the native resolution 1024x768.

    This is great Per. Maybe you should set the thread as solved and write your answer in teh first post as others won't need to try the editing of the xorg file option when all you need is to turn off "mirror screens"
