    Log off.

    Flip to the console via CtrlAltF1.

    Log in.

    Type
    Code:
    sudo chown -R user:user /home/user
    exit
    where user is your login name.

    Flip back to the login window via CtrlAltF7.

    Log in.

    Better? If so, mark this (SOLVED).

    Whoops.

    Did you try to move this stuff to a FAT32 or NTFS drive? It's acting like all the permissions are wrong. You didn't explain clearly what you were trying to do, nor what you did do...


    Boot from a LiveCD in "Try it" mode.

    Open a terminal window.

    Type in:
    Code:
    sudo fdisk -l
    One of the listed partions will be "ext3". Make note of the device. We'll assume that was "/dev/sda2", but use the correct one...

    Code:
    sudo mount /dev/sda2 /mnt -text3
    ls -l /mnt/usr/bin/sudo
    *should* look like:
    Code:
    -rwsr-xr-x 2 root root 143656 2009-06-22 12:15 /usr/bin/sudo
    If the mode and ownership don't match that, you need to backup your data and reinstall Ubuntu.

    Do you have a Windows partition? The fdisk command above will have displayed which device that is. Let's assume it was /dev/sda1 and that it's really big.

    Code:
    sudo mkdir /mnt2
    sudo mount /dev/sda1 /mnt2 -tntfs
    cd /mnt
    tar cjf /mnt2/emerg-backup.tar.bz2 home
    That'll take awhile, but you'll have a backup.

    Now, reinstall Ubuntu.

    Then open a terminal window and mount that Windows partition with the backup on it, and restore the backup:
    Code:
    sudo mount /dev/sda1 /mnt -tntfs
    cd /
    sudo tar xjf /mnt/emerg-backup.tar.bz2
    sudo chown -R $LOGNAME:$LOGNAME $HOME
    That will put you close to where you were...
