    Display error notification on bootup

    Since upgrading to Lucid, I am getting the following dialog warning on login:

    'Could not apply the stored configuration for monitors
    X Server does not support size requested'

    Im using the current proprietary NVIDIA graphics driver with dual heads. My display is fine, but the warning every time I login is annoying. After googling around I found this thread: http://ohioloco.ubuntuforums.org/sho....php?p=9044815. I tried going to Monitor Preferences as suggested. My resolution as displayed in the default tool is set to 3840 x 1200, which I suspect is the issue forcing the dialog, but I cant change the resolution, refresh rate or rotation from the Monitor Preference dialog box. dino99's response (in the referenced post) about xorg.conf not being needed anymore seems relevant. How can I resolve this issue and get rid of this annoying warning? Is there a configuration that I can update with a supported resolution to placate lucid?

    dino99 had good recommendations. To implement them:

    Code:
    sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.orig
    To reverse:
    Code:
    sudo mv /etc/X11/xorg.conf.orig /etc/X11/xorg.conf
    The other suggestion is just a terminal command:
    Code:
    Xorg -configure

    Re: Display error notification on bootup

    Moving the xorg.conf file "fixes" the problem in that I dont get the X Server warning and I can update my monitor preferences via the default utility, but it removes my dual head display configuration therefore I loose one of my monitors. Of course reconfiguring my twinview display through the NVIDIA utility recreates xorg.conf. I get my 2 display back, but also the annoying X Server warning. And, as expected Im again unable to update the monitor preferences via the default tool which has the resolution set to 3840 x 1200 as before.

    Running Xorg -configure results in the following:


    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
    at http://wiki.x.org
    for help.

    Re: Display error notification on bootup

    Obviously, something is detecting my xorg.conf file and its not happy about that configuration. The NVIDIA driver is clearly satisfied as my display works perfectly. Whatever is unhappy with my xorg.conf configuration seems to have been introduced int 10.04 LTS as I did NOT have this issue before upgrading. Ideas?

    Re: Display error notification on bootup

    What exactly is the xorg.conf that nVidia creates?
    Code:
    cat /etc/X11/xorg.conf
    You can force the correct screen resolution in xorg.conf, I just have no idea how to do it. I suggest you search around the forums and google for some ideas.

    Below is the contents of my xorg.conf file. Which as far as I can tell looks valid. And as I said, there didnt seem to be any issue until I upgraded to Lucid.

    should help, specifically the section titled "Adding custom modeline". You can edit xorg.conf with:
    Code:
    gksudo gedit /etc/X11/xorg.conf

    Re: Display error notification on bootup

    That looked promising, but alas, no. Adding the custom mode line didnt make a difference. The X server config error persists.

    However, in the process of generating the modeline text, I noticed that in the NVIDIA display config utility my X Screen 0 dimension is 3840x1200 pixels (1147x372 millimeters).



    This seems to correlate nicely with the wacky resolution that is reported in the default Monitor Preferences utility, that I am unable to alter and seems likely an "unsupportable" resolution.



    Coincidence? Perhaps.

    I suspect that new Lucid updates are seeing that reported twinview display dimension (1920+1920 x 1200) and reporting this naive X Server Config warning. Maybe this is a bug.

    You want your desktop stretched across two monitors?
    Did you try dual xscreens?
