I
am running Ubuntu 11.10 "Oneiric Ocelot", and in trying to install the nvidia CUDA developer drivers
I switched to a virtual terminal (Ctrl-Alt-F5) and stopped lightdm (installation required that no X server instance be running) through sudo service lightdm stop.
Re-starting lightdm with sudo service lightdm start did
not work: A couple of * Starting [...] lines where displayed, but the process hanged. (I do
not remember at which point, but
I think it was * Starting System V runlevel compatibility.
I manually rebooted my laptop, and ever since booting seems to hang, usually around the * Starting anac(h)ronistic cron [OK] log line (not consistently at that point, though).
From that point on,
I seem to be able to interact with my system only through a tty session (Ctrl-Alt-F1).
I've tried purging and reinstalling both lightdm and gdm, as well as selecting both as the default display managers (through sudo dpkg-reconfigure [lightdm / gdm] or by manually editing /etc/X11/default-display-manager) through both apt-get and aptitude (that shouldn't make a difference anyway) after updating the packages, but the problem persists.
Some of the responses
I'm getting are the following:
After running sudo dpkg-reconfigure lightdm (but
not ... gdm)
I get the following message:
dpkg-maintscript-helper:warning: environment variable DPKG_MATINSCRIPT_NAME missing
dpkg-maintscript-helper:warning: environment variable DPKG_MATINSCRIPT_PACKAGE missing
After trying sudo service lightdm start or sudo start lightdm
I get to see the boot loading screen again but nothing changes. If
I go back to the tty shell
I see lightdm start/running, process <num> but ps -e | grep lightdm gives no output.
After trying sudo service gdm start or sudo starg gdm
I get the gdm start/running, process <num> message, and gdm-binary is supposedly an active process, but all that happens is that the screen blinks a couple of times and nothing else.
Other candidate solutions that
I'd found on the web included running startx but when
I try that
I get an error output [...] Fatal server error: no screens found [...]. Moreover,
I made sure that lightdm-gtk-greeter is installed but that did
not help either.
Please excuse my
not including complete outputs/logs;
I am writing this post from another computer and it's hard to manually copy the complete logs. Also,
I've seen several posts that had to do with similar problems, but either there was no fix, or the one suggested did
not work for me.
In closing: Please help!
I very much hope to avoid re-installing Ubuntu from scratch! :)

I did
not manage to fix the NVIDIA kernel driver as per your instructions.
I should perhaps mention that
I'm on a Dell XPS15 laptop with an NVIDIA Optimus graphics card, and that
I have bumblebee installed (which installs nvidia drivers during its installation,
I believe). Issuing the mentioned commands
I get the following:
~$uname -r
3.0.0-12-generic
~$lsmod | grep -i nvidia
nvidia 11713772 0
~$dmesg | grep -i nvidia

Also, running aptitude search nvidia gives me the following:

I've tried manually installing (sudo aptitude install <package>) packages nvidia-common and nvidia-settings-updates but to no avail. For example, sudo aptitude install nvidia-settings-updates returns the following log:

The same happens with the Linux headers (i.e.
I cannot seem to be able to install linux-headers-3.0.0-12-generic). The output of aptitude search linux-headers is as follows:

I did try purging and reinstalling any nvidia driver packages, but it did
not seem to make a difference,
My xorg.conf file contains the following:
