Hi guys, if you have problem while doing update and upgrade on Ubuntu, especially on the latest Ubuntu 12.04 Precise Pangolin, you should try one or more the following solutions:
- Install Ubuntu desktop
- sudo apt-get install ubuntu-desktop
- sudo reboot
- Reinstall gdm/ligtdm
- sudo apt-get install --reinstall gdm
- sudo reboot
- Try the following tricks
- sudo chown lightdm:lightdm -R /var/lib/lightdm
- sudo chown avahi-autoipd:avahi-autoipd -R /var/lib/avahi-autoipd
- sudo chown colord:colord -R /var/lib/colord
p.s: Although you cannot entering x-window (graphical mode), you still solve the problem via command line mode by pushing Ctrl+Alt+F1 while your PC hang!
