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.
