I have Ubuntu 12.04 installed on my machine (Dual boot). It was working fine till today. I executed the following commands in the terminal, and when I restarted I get a Purple Screen of Death.

sudo apt-get autoremove

I also had Qt Designer installed, so I removed it using

sudo apt-get remove qt4-dev-tools
sudo apt-get remove qt4-docs
sudo apt-get remove qt4-assistant
sudo apt-get remove qt4-linguist

I had already tried the following:

  1. In recovery mode, it always hangs at this part.

    * Starting MySQL server [OK]

  2. From a Ubuntu Forum post, I tried doing Ctrl+Alt+F1 and then

    sudo apt-get update
sudo apt-get upgrade
sudo apt-get install fglrx
sudo aticonfig --initial

But this always ends with aticonfig:No supported adapters detected.

Any help would be greatly appreciated.

P.S : Please do not mark this as duplicate as I've gone through many threads and I'm not able to find a solution myself.

EDIT: it now hangs at Checking battery state itself :( . I've referred to this http://ubuntuforums.org/showthread.php?t=1606130 but I'm unable to find any solution.

    Edit your boot parameters in grub (press e then look for the line ending in quiet splash) remove quiet splash and write verbose. Then try booting your system again. – Braiam Jan 08 '14 at 01:36

If it is hanging at * Starting MySQL server [OK] you should try disabling MySQL server (via Ctrl+Alt+F1) and then see if it continues past that stage when you reboot.

You can do this as follows:

sudo nano /etc/init/mysql.conf

Comment out (using a hash sign) the start on section - and this section only! If it spans multiple lines, add a hash sign to each line.

For example:

#start on (net-device-up
          #and local-filesystems
          #and runlevel [2345])

To restore your ubuntu 12.04 do a version upgrade to Ubuntu 12.10 via USB and you will have the problem fixed.

You could also do a clean install of the latest 13.10 to avoid any future problems as it is the most updated stable version for Ubuntu and as you are not an Enterprise you don´t need LTS versions.

PS: if you boot into the system run the following on the terminal:

sudo apt-get update

sudo apt-get -f upgrade

sudo apt-get -f dist-upgrade (this last one doesn´t update your system to a new Ubuntu verison)

Hope it helped you out.

    They don't have to upgrade to 12.10 just to fix this. This answer is incorrect, however it is still an attempt at an answer. – Thomas Ward Jan 08 '14 at 02:11
