Ubuntu – Ubuntu 13.04. fail to start after installing nvidia drivers (Vostro laptop)

13.04compizintel graphicsnvidiaunity

Everything worked fine in 13.04 Ubuntu but then i installed nvidia-drivers-103 Now it does not load into login screen at all. I see blank purple screen during start-up and then just blank black screen appears and nothing happens after.

I booted into recovery mode and removed nvidia drivers, that did not helped. I noticed i had broken Unity environment in recovery mode (no launcher or toolbars, just wallpaper) so i followed :

Unity doesn't load, no Launcher, no Dash appears

where i reseted my unity/compiz back but this did not helped me to boot so finally i installem gdm and now i have compiz and unity fully removed and nvidia drivers too. I still cannot boot, only recovery mode works fine.

What i should try next to have Unity and Compiz happily working ? Which logs should i check and what could be wrong ?

I would expected that unity/compiz is problem but as i still cannot start my OS i guess the reason is much more deeper than i expected. How to restore original version of graphics drivers ? Obviously just removing NVidia drivers did not restored original configuration.

HW : laptop Vostro 3750, Nvidia GT 525M, Intel Mobile HM67 Chipset

I have a dell Latitude E6500, and got the same problems the only solution I found was the following :

  1. Switch to console mode: Alt+Ctrl+F1
  2. Kill x server: sudo service lightdm stop
  3. Remove nvidia drivers: sudo apt-get remove --purge nvidia*
  4. Generate new xorg.conf file: sudo X -configure -- this will create xorg.conf. A new file in your current dir
  5. Rename and move: sudo mv xorg.conf.new /etc/X11/xorg.conf
  6. Return to GUI: sudo start lightdm

Of course I would prefer a better solution
