    Unable to get to desktop after 11.10 upgrade

    After I upgraded to 11.10, my virtual machine was no longer booting. It would just sit at the purple Ubuntu screen. I've seen a couple of different posts including this one about Ubuntu not booting after upgrading. I've followed all of the steps in the given post, and I have Ubuntu booting. I get to a command line prompt asking me to log in. My question is, how do I get my desktop back?

    Unlike the people in the two other posts I've found, I cannot get past the Ubuntu purple screen by selecting an older version of the kernel. Any ideas?

    If you get to a command line prompt log in give password and:
    Code:
    sudo /etc/init.d/lightdm restart
    See if that gets you to a log in screen.
    If not:
    log in
    Code:
    sudo dpkg-reconfigure lightdm
    choose lightdm instead of gdm if a selection.

    I issued the first command and it started doing something and then started stopping a bunch of processes, and then got stuck. Upon running the second command, I'm told "dkpg-reconfigure: command not found"

    I think you meant dpkg

    I set it to lightdm and I got two warnings saying:
    environment variable DPKG_MAINTSCRIPT_NAME missing
    environment variable DPKG_MAINTSCRIPT_PACKAGE missing


    Rebooting now...


    And it boots to a blank screen with a blinking cursor in the upper left hand corner of the screen.

    Heres a crude way I fixed this issue, It works with 10.10, 11.04, and 11.10. Make a Ubuntu install disk and boot to up to where it ask you if you want to install or demo. click on the power button and choose to shut down. Remove the disk and reboot. It works for me.

    That did nothing.

    Boot into your Live Cd (install cd using Try Ubuntu) get internet working.
    Code:
    sudo fdisk -l
    (lower case L)
    pick out your linux install.
    I will use sda5 for this use your own and copy and paste these one at a time.
    Code:
    sudo mount /dev/sda5 /mnt
    Code:
    sudo mount -o bind /dev /mnt/dev; sudo mount -o bind /dev/pts /mnt/dev/pts; sudo mount -o bind /proc /mnt/proc; sudo mount -o bind /sys /mnt/sys
    Code:
    sudo cp /etc/resolv.conf /mnt/etc/resolv.conf
    Code:
    sudo chroot /mnt
    Code:
    apt-get purge gdm
    Code:
    apt-get install -reinstall lightdm
    Code:
    apt-get update; apt-get upgrade
    Code:
    dpkg --configure -a
    Code:
    exit
    Code:
    sudo umount /mnt/dev/pts && sudo umount /mnt/dev && sudo umount /mnt/proc && sudo umount /mnt/sys; sudo umount /mnt
    Code:
    sudo reboot
    Seems like a lot but all we are doing is getting into the / of your install and getting rid of
    gdm, reinstall lightdm and updating and upgrading system and checking for broken packages.
    You seem to have something amiss and cannot boot properly this might do it for you.

    I ran all of those commands. I can now boot to a command line for linux 3. Still no desktop. The only issue I had, was I was unable to umount /mnt/dev.

    Do not worry about it.

    Can you run
    Code:
    startx
    or
    Code:
    sudo /etc/init.d/lightdm restart
    I can now boot to a command line for linux 3
    Does this mean you can boot into Unity but not Gnome3 (gnome-shell)
    or not getting any Graphic User interface at all in both.
