Installed Lucid 10.04.1, updated and using default video drivers, everything works.
When I installed nvidia drivers version 195, more times than not I drop to a VT terminal. From there I have to login and then issue "startx". Everything works after that. Extensive search revealed nothing.
Output of "/etc/X11/xorg.conf" Although I can't see why this would come into play because sometimes it works. that should nullify xorg config.:
Identifier "Default Screen"
Identifier "Default Device"
Option "NoLogo" "True"
I checked all the relevant logs, all to no avail. Just a guess would be that something is in contention with stating X before of after nvidia drivers.
I removed quiet & splash. Makes no difference.
