When I start up Ubuntu (11.10), no graphical interface loads. This is the case both in normal and recovery mode. Instead I'm being presented with a console, logged as 'root@ubuntu'. From there I can call
exit and then log into my default (and only) account, and once there I can load the unity with the command
startx but to get to unity I have to repeat above everytime I start up the PC.
I hope some of the details below might be able to indicate what's exactly the problem. I tried several solutions I found on the web, but to no avail.
My graphics card: Nvidia GeForceGT 540M
Result of typing in console:
unity WARNING: no DISPLAY variable set, setting it to :0 unity-panel-service: no process found compiz (core) - Fatal: Couldn't open display :0
Result of typing
nvidia-settings ERROR: The control display is undefined; please run 'nvidia-settings --help' for usage information.

The problem occurs with both xorg.conf versions. I tried installing, purging, reinstalling nvidia drivers, editing blacklist as per NVIDIA drivers not working after upgrade. Why can I only see terminal? all to no avail. I would greatly appreciate any pointers that would help me resolve the issue.
The reason I tried messing with nvidia drivers in the first place is that some gtk/OpenGL stuff didn't work correctly. In particular, the Xorg.0.log contains the following error:
(EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found)
Well, fixing the lack of any desktop whatsoever is the priority, but should you happen to know how I might be able to resolve the GLX extension problem, I would be happy to keen to hear you out.
