dell inspiron crashes after NVIDIA 304.43 update

Hello ,

as I can see (from my Ubuntu 12.04) the Nvidia-Current driver is 295.40 so
you updated the driver via PPA . Possibly X-swat ?

Remove the PPA and install again Nvidia-current.

You said crashing , can you login to Desktop Environment , or you cannot ?

FIRST SUGGESTION:

If yes then open a terminal (Ctrl+alt+t keys combo) and give the results of this command

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
find /etc/apt -name '*.list' -exec bash -c 'echo -e "\n$1\n"; cat -n "$1"' _ '{}' \;
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Copy - paste it from here to terminal for more accuracy.

SECOND SUGGESTION:

If you cannot login to Desktop Environment then boot from Recovery Mode and click ROOT

then give bellow commands with order (write them down somewhere , or mobile photo them)

++++++++++++++++++++++++++++++++++
mount -o rw,remount /
apt-get purge nvidia*
apt-get install ubuntu-destkop
rm /etc/X11/xorg.conf
reboot
+++++++++++++++++++++++++++++++++

After above commands , hopefully you will be able to boot and login in Desktop Environment and you can proceed with command from first suggestion.

Thanks
