    OK this is now not a joke anymore- after 10 mins of not using the computer it just shuts down and goes to the login screen - I cant access the screensaver pael to see whats happening, when ai do it just shuts down to the login screen -
    is there a way to reinstall the screensaver program, or should I reinstall ubuntu? - If I have to reinstall ubuntu how do I do it, and how do i save my settings - I am dual booting

    I think I have solved it - I selected screensaver - system preferences screensaver, and quickly clicked into the pane that has the different screensavers, and got a random screensaver, this stopped the computer shutting down, then I deselected the after 10 mins option, and now I think it works - the problem screensaver seems to have been the one called matrix view - the one that draws faces in the falling matrix letters - is this a standard screensaver - or is it one I downloaded from somewhere (i cant remember) - if it is a downloaded one how can I delete it - where are the screensaver files kept?
    Hope this helps someone if they have the same problem.

    I have that ss but it works fine for me.

    I guess somewhat you video driver cannot handle that ss. Does Hardware drivers in the system menu > administration show any uninstalled drivers?

    On the top panel click

    system > administration > Hardware drivers.

    Does it show any non-selected drivers?

    Well, then your video driver cannot handle matrixview for some reason and I don't think there is anything that you can do about it.

    You can get rid of matrixview by deleting the following files:

    Code:
    /usr/lib/xscreensaver/matrixview
    /usr/share/applications/screensavers/matrixview.desktop
    /usr/share/applnk/System/ScreenSavers/matrixview.desktop
    /usr/share/man/man1/matrixview.1.gz
    /usr/share/xscreensaver/config/matrixview.xml
    If I remember correctly, after deleting these files the matrixview will be greyed out in screensaver preferences and it will be unclickable. There is a way to get rid of that line completely from ss perefences but I don't remember it.

    Are you sure you weren't telling the screen saver to lock the screen, that will also take you to a login window. It's great if you don't want anyone to use your computer if you are away from it.
