    I suspect that's because that line should be:

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

    The command is
    Code:
    sudo gedit /etc/X11/xorg.conf.svideo
    gedit is the text program, which is opened with super user rights using the sudo command. /etc/... is the path you are opening to edit. You'll get used to using bash commands. I hated them at first, but now it's kind of nice.

    Re: How To: Svideo / Dual Monitor(xinerama) / Dual Monitor(cloned desktop) on i945

    Hi, I followed all the steps, and unfortunatelly I can no manage to have my Acer Travelmate 2410 (Intel 915GM/GMS, 910 GML Express Chipset Familiy) with my external screen (Acer AL1917) working as dual screen. When I switch it to dual, I get a blank screen in my computer and a bleu one in the external screen. Any ideas? This is the file content:

    # /etc/X11/xorg.conf (xorg X Window System server configuration file)
    #
    # This file was generated by dexconf, the Debian X Configuration tool, using
    # values from the debconf database.

    # (Type "man /etc/X11/xorg.conf" at the shell prompt.)

    Are you sure that you have the HorizSync and VertRefresh correct for the different monitors?

    xorg may have the two screens around the wrong way, try starting with the same resolution for both.

    Lastly, if you are using Feisty, try getting the two screens working without Xinerama first. (You get separate sessions on each monitor rather than one across the two).

    Re: How To: Svideo / Dual Monitor(xinerama) / Dual Monitor(cloned desktop) on i945

    @veloce
    @Hasen_A

    Thanks guys, that did it. Now the next problem...

    I do get an output, but not the correct one, the 2nd screen goes white with a black border(kinda like in the days of ZX Spectrum). The main screen goes black.

    If I ctrl-del-backspace then it allows me to logon on but then goes to the situation described above.

    To remedy I have to boot into safe mode and switchmon 1.

    any suggestions?

    Thanks in advance!

    Re: How To: Svideo / Dual Monitor(xinerama) / Dual Monitor(cloned desktop) on i945

    Another thing that goes wrong is that the card cannot cope with the screen depth of 24 bit when running dual screen. This is probably a memory issue. Make sure you allow for it to drop to 16bit (or lower with older equipment).

    This means having these options included in the screens sections of the xorg.conf.

    For those who have asked here's my xorg.conf:

    Re: How To: Svideo / Dual Monitor(xinerama) / Dual Monitor(cloned desktop) on i945

    @veloce, thanks again. I got it working. Simply by choosing clone output instead of extended desktop.

    Still not working properly though I still have a big black border around the 2nd screen output.

    any suggestions ?

    thanks!

    That sounds like a resolution issue. xorg is not driving the screen at a high enough resolution.

    A couple of possibilities:
    1. with clone mode it may be driving both screens at the same resolution
    2. xorg hasn't got the refresh and sync ranges for the monitor

    Sorry you may have answered these before:
    Are you running Fiesty? If so, try turning of clone mode (as well as leaving xinerama off).
    Do you have an Intel graphics card? If so, try setting modes for the screens in the 915reolution config file.

    Yes, I am using Feisty, the border are only on the TV screen. When I swtich off clone mode the res goes back to 1024x786 on the laptop from I think 800x600.

    Yes, I have an Intel integrated graphics card. How do I set modes for the screens in the 915reolution config file?
