I thought that my ATI driver was not running well so I wanted to re-instal it completely. I did:

sudo apt-get remove --purge fglrx*
sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon

and after a boot I wanted to intal the ATI driver BUT at the boot no more signal to my screen.

Since, every time I turn on my PC it gets to purple screen and then screen shuts down !

Note that:

  • Even if the screen is off, PC seems to be running almost well: I m still able to use my network to access data shared with NFS.
  • Using live USB I have no screen problem.
  • I tried to plug my screen on an alternative output but it did not work.
  • I tried CTRL+ALT+F1 while being on purple screen but it does not do anything, screen shut down anyway.
  • I m going to try the SHIFT thing and learn from blackscreen wiki...

FYI, you actually ended up uninstalling BOTH the AMD driver and the open source driver. –  Uri Herrera Nov 28 '11 at 0:15

Unfortunately it appears you left out a few commands;

sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri fglrx-modaliases
sudo dpkg-reconfigure xserver-xorg

Your X server configuration likely lists no driver so it will not load properly. You may be able to recover by following the guide by effenburg on this Ubuntu Forums post

yes I though that my open source driver was still there and I was on my way to run the install command just after reboot. But it appears that this was not a good idea, oups! Thank you for your link it helped me to solve the issue. –  Boris Nov 28 '11 at 22:05
