I just switched my graphics to use the propriety driver instead and after reboot it stop at >starting version 219".

Nothing works. I cannot get terminal by Ctrl+Alt+F1 or anything else.

If I press the power button it shows the Ubuntu logo and powers off.

How can I get back to the generic driver?

  • ATI HD5450 graphics card. A friend told me never to use the propriety drivers, but I decided to check if I get better graphics, multiple screen management etc. after reading this article link – Nazeem Jansen Nov 06 '15 at 08:50
  • Boot to recovery https://wiki.ubuntu.com/RecoveryMode and see http://askubuntu.com/questions/68306/how-do-i-remove-the-proprietary-ati-drivers – Mark Kirby Nov 06 '15 at 08:58
  • You SHOULD use a prop driver. You can use this guide for installing the correct driver http://askubuntu.com/questions/124292/what-is-the-correct-way-to-install-proprietary-ati-catalyst-video-drivers-fglrx – Mark Kirby Nov 06 '15 at 09:01
  • Ok I tried all the advanced options, but got stuck on error about "running in low graphics mode". I rebooted about times and when at the same screen got to the terminal and the machine booted the the login screen. After login it just kicked me out again without any errors. I tried my other desktops and managed to login LXDE. Now to find how to change back from the propriety driver in LXDE. Ok I found it and switching back to the open source driver. Ok after rebooting back to the same 219 error. – Nazeem Jansen Nov 06 '15 at 09:05

Follow this post to get into recovery mode:

How do I boot into recovery mode?

In essence:

  • Switch on your computer.
  • Wait until the BIOS has finished loading, or has almost finished. (During this time you will probably see a logo of your computer manufacturer.)
  • Quickly press and hold the Shift key, which will bring up the GNU GRUB menu. (If you see the Ubuntu logo, you've missed the point where you can enter the GRUB menu.) **
  • Select the line which starts with "Advanced options". *
  • Select the line ending with "(recovery mode)"

And then remove all ATI propietary drivers following this other post:

How do I remove the proprietary ATI drivers?

  • Try to completely remove your ATI drivers from your system:
sudo apt-get purge "fglrx.*"
  • Remove your xorg.conf
sudo rm /etc/X11/xorg.conf
  • Reinstall xorg completely
sudo apt-get install --reinstall xserver-xorg-core
libgl1-mesa-glx:i386 libgl1-mesa-dri:i386 libgl1-mesa-glx:amd64
libgl1-mesa-dri:amd64
  • Re-configure Xorg
sudo dpkg-reconfigure xserver-xorg
  • Reboot
sudo reboot

  • Thanks. I will be looking at using the prop drivers as mentioned now that I know how the fix this problem, but on the page link I do not see drivers for 15.10 or should I just use the method as with 14.04? – Nazeem Jansen Nov 06 '15 at 10:19
  • @NazeemJansen Yes follow the 14.04 / 14.10 , there seems to only be one option for Ubuntu on that card anyway (Ubuntu x86_64) so it should be fine. – Mark Kirby Nov 06 '15 at 10:37
