    I did every step, and its fine until the last command

    Code:


    xrandr --addmode lvcd1 1024x768_60.00

    Output:

    xrandr: cannot find output "lvcd1"


    Thank you.

    Re: Low Resolution with Ubuntu 9.10

    I am going to try changing the Xorg.conf

    following this http://ubuntuforums.org/showthread.php?t=269052

    Because reinstalling the desktop software hasn't done any changes.

    Try running

    sudo Xorg -configure

    to generate a completely filled out xorg.conf

    It should detect the capabilities of your display and put the proper modes into the xorg.conf explicitly.

    This is what I get:

    Fatal server error:
    Server is already active for display 0
    If this server is no longer running, remove /tmp/.X0-lock
    and start again.


    Please consult the The X.Org Foundation support

    for help.

    Re: Low Resolution with Ubuntu 9.10

    I have a similar problem using 9.10 as a VM in Virtualbox

    Any ideas how to get a higher Resolutuion without the Guest Additions ?
    I'm asking because I use Ubuntu 9.10 as a guest and connect to them via x11vnc.
    But when I install then GA I can't use "right mouse click" anymore.

    I tried the xorg.conf but this won't work in 9.10 anymore. When I make this my Gnome crashes and I don't have a desktop anymore.
    There's talk about a new monitors.xml file which keeps the settings, but i tried with this a lot and it doesn't take effect.
    As I have 2 resolutions 640x480 and 800x600 from the start. Where's the file for this input ?
    No one really seems to know.

    Re: Low Resolution with Ubuntu 9.10

    [QUOTE=Sebastian Burch;8240958]

    Since ver. 9.0 there have been problems with changing monitor resolution. The settings of 600x800 and 400x600 seem to be defaults in the instructions. But it's possible to change things.

    Check out this document: "HOWTO: change resolution/refresh rate in Xorg"

    Also: Find your monitors manual (manufacturers website and Google are useful). Look for horizontal sync and vertical refresh rates, also if bandwidth or maximum dot clock / pixel clock is mentioned.

    What I did was to follow suggestion of "fabricator4" who advised editing the xorg.conf file. I did the following:

    "sudo gedit /etc/X11/xorg.conf"

    In the monitor section, type in your own Horiz and Vert range. Mine was:

    Section "Monitor"
    Identifier "Configured Monitor"
    HorizSync 31-101
    VertRefresh 60-160
    EndSection

    Save. Then, Ctrl-Alt-Fx to get a terminal. Enter your name and password. Type: "sudo /etc/init.d/gdm stop". Enter. The GUI display will stop. Then type "sudo /etc/init.d/gdm start". And Ctrl-Alt-F7 to bring up the GUI display screen.

    I hope this is helpful. If not check out the posts by searching for "monitor resolution".
