I am a Ubuntu user for over 15 years now and love it except for the difficultly in installing display drivers sometimes. This year I have been unable to install one on my Desktop successfully which has a Nvidia Geforce 9800GT card. I can get it to install without errors but every time I reboot it will not boot to the desktop and stops at starting x. It looks like its trying as the screen flashes and some graphical characters flash up and then it tries all over again getting stuck in a continuous loop. I have tried booting to a shell and removing and purging the Nvidia driver but it refuses saying filesystem is read only. It's impossible to get out off unless I do a re-install. I've tried every tutorial online and tried both of the drivers offered by Nvidia & Ubuntu. I always end up having to use the nouveau driver which refuses to play videos without being very jerky.

Any help to get it working?
