    New LTSP isntallation

    I just finished installing LTSP on a 10.04 server.
    I tried to log in with a diskless PC.
    The logon screens come successfully but when I am putting the user name and password a terminal window opens at the top left of the screen.
    I have added a test user with adduser command.
    How I am suppose to log in and load the graphical desktop?
    Or because I have installed Ubuntu 10.04 server edition I will never get a graphical desktop???

    Thanks in advance.

    Re: New LTSP isntallation

    Okay, first, chances are your gonna have to rebuild your images from the ground up, or you could chroot to the LTSP root folder and add packages through there.
    To do the chroot, login to the server and type:

    sudo su

    Then were gonna wanna chroot to the ltsp chroot:

    chroot /opt/ltsp/i386
    (/opt/ltsp/amd64 if you built the chroot for amd64 based systems)

    Now we have to mount /proc in the chroot:

    mount -t proc proc /proc

    Now to update apt for our packages:

    apt-get update

    And finally we install ubuntu desktop:

    apt-get install ubuntu-desktop

    Now to update our packages:

    apt-get dist-upgrade

    Heres where you exit the chroot:

    exit

    Now to update our LTSP kernels:

    ltsp-update-kernels

    Now unmount /proc:

    sudo umount /opt/ltsp/i386/proc

    Now update out LTSP image:

    ltsp-update-image

    To exit sudo just type:

    exit



    Thats the hard way, if you have nothing to reconfigure in your setup, i recommend to do this:

    Create this file:

    /etc/ltsp/ltsp-build-client.conf

    Within this type:

    # For 64-bit clients change this to ARCH="amd64" etc.
    ARCH="i386"
    # For edubuntu change to FAT_CLIENT_DESKTOP="edubuntu-desktop"
    FAT_CLIENT_DESKTOP="ubuntu-desktop"
    LATE_PACKAGES="
    gimp
    flashplugin-nonfree
    "

    Now save the file and run:

    ltsp-build-client --purge-chroot

    and your done

    This should work

    Re: New LTSP isntallation

    Thank you very much for your answer.
    I'll try it first think tomorrow.
    To be sure I understand correctly, if I had installed LTSP on an ubuntu desktop and not on a server I wouldn't have to do that. Correct?
    After this configuration I will have fat clients instead of thin? I.e. local hardware dependable?

    Re: New LTSP isntallation

    Yeah, if you used ubuntu desktop you wouldnt have to do this, im stabbing in the dark at what i do to change desktop environment, but it should work I actually run my LTSP servers off an ubuntu desktop machine, but i used to deploy kubuntu instead of Gnome
    As for hardware - im not entirely sure, i assume the server still processes everything, just with the added desktop environment, but ill look into that for you. As for hardware dependance, any THIN client should still be capable of running the desktop nvironment locally anyway, which would also take some strain off the server allowing for more clients if that doesnt work, just install the dektop edition - it runs fine as a server, aswell as LTSP i run DHCP, DNS, Samba4 and Squid aswell as handling 25 clients at half the load

    Thanks so much. I'll give it a try tomorrow. I am new in Linux and I am trying to experiment a litle bit .
    I tried to implement a thin client environment with XP clients and their images stored in a ubuntu server with no luck... (I couldn't find enough info, I might open a new thread..) So now I want to try out the LTSP!

    OK. I did what you told me. I think now I have to somehow force my test user to login to the graphical interface. Is that correct? Because I've logged in with my test user and I still get the terminal window...
