Multiple X servers

[zkab]

Had some problems going from 8.10 -> 9.04 with my onboard Nvidia GeForce 6150 ... this is the first time I run into difficulties with Nvidia ... got a black screen with a cross ...
After some Google-ing I followed the guidelines in https://help.ubuntu.com/community/NvidiaManual and now I guess that I am closer to the finish line ... after a boot I receive (after Ubuntu/Nvidia splash) a window telling me that 'There already appears to be an X server running on display :0. Should another display number by tried? ...'

Whatever I answer I can't get around this message ... /etc/X11/xorg.conf and /var/log/Xorg.0.log seem to be OK

What's wrong ?

There appears to be two device sections one using the Opensource "nv" driver the other using the "nvidia" driver. Try remarking out the generic section.

note always make a copy of the file before modifying it.

If that does not work try replacing "nvidia" with "vesa"
That should at least get the GUI working.

I removed the Generic section in xorg.conf ... same bad result
Then I changed nvidia -> vesa in xorg.conf ... problem remained and as you can see from the log it complains that vesa module can't be loaded ... hmmm

Something is very wrong but I can't figure out what

Ok reverse it remove the Videocard0 section and also the corresponding screen section.

Been away from computers for a while ... but the problem still remains
Tried to make the xorg.conf more clean but the message 'There already appears to be an X server running on display :0 ...'

Don't understand since the log file shows no errors
