Thread: start kde on startup without monitor

  1. #1

    Default start kde on startup without monitor

    hey,

    i have several pc that run on linux that are supposed to only process data etc. since i dont really work on those machines it doesnt make sense to have a monitor for each of them, same applies for a kvm switch ..

    so i figured the best way is using VNC for maintenence which runs just fine.

    the thing is once i restart a machine that has no monitor plugged in it will not run kde automatically, which means i have to plug in a monitor, start kde which is annoying.

    i believe there is a way to make kde run w/o having a monitor plugged in, but the google research i made didnt really return helpful results..

    thanks for any help ...

    Thats odd, I have never heard of that happening, as I have always been able to unplug a monitor and have the system work normally without it.

    Just a thought but try adding the option

    "UseEDID" "FALSE"

    to xorg.conf.

    That pretty much tells it to ignore the monitor.

    Hi
    Just to clarify, you have to manually enter the user name and password
    to login to kde or your system is set to autologin?

    Have you looked at FreeNX or NX (nomachine.com) as an alternative to
    vnc, it uses ssh which is more secure and is probably a better option

    If you used VNC setup in Yast, then the default is to take you to the login screen, that happens even if a computer has a monitor and is being used by someone.

    In other words, if my wife was using her computer, and I wanted to do some updates on it while she was using it, I could use VNC to log in, do the updates and anything else I wanted to do all while she was using it and she would never even know it.

    I think your system is indeed starting KDE, the behavior you are seeing is VNC the way Yast sets it up.

    Plug a monitor into one of the machines that you think hasn't started KDE and you will indeed see that a desktop is already running.

    hey

    here is what happens

    - i start the pc with monitor
    - auto login is switched on so all i have to do is wait until its finished booting and all that and im all set to go


    - starting the pc w/o monitor
    - once i think its done booting i plug in the monitor to see what happened ..
    - the pc is in the command line asking me to login .
    - once i login, i need to enter startx to start kde ...

    so for some reason this doesnt happen automatically, and i think vnc is not even involved here

    Hi
    Just a couple of things, have you run ps -ef to check that X/vnc isn't
    running and you are just at a different VT because of that.

    To check this use ctrl+alt+F7 (GUI).

    no x is not even running..
    thats the thing ... i think it checks whether a monitor is plugged in or not and then starts the x server or not ...

    so what i need is to find a way to make the x server start nevertheless

    Hi
    Very strange, so is there anything in the Xorg logs (in /var/log). You
    may need to look at using Xvfb (virtual frame buffer).

    Like I said, you may wish to try the NX's... no grief, they just work.
