Before I start, this is on my inspiron 7707 windows 8.1/Ubuntu 14.04 dual boot which has Intel HD 4000 and Nvidia GeForce GT 750m.
I have been trying to update my Nvidia drivers, which by itself is proving to be horrifically difficult so following some instructions here or on another ubuntu forum (cant remember and dont have access to the history) I purged nvidia and bumblebee as well as prime, I believe, though I'm not sure.
After downloading the 352.55 drivers I eventually just switched to tty1 and ran the command
sudo service gdm stop
then executed the nvidia driver .run file, where I encountered an error along the lines of "Could not load kernel module", so I hit enter and then
sudo service gdm start
and then, well, nothing. tty7 was just a black screen with the underscore cursor at the top left, and it seemed to repeatedly try to reload which prevented me from using another tty until I stopped gdm again. Can anyone give me an idea about what to do? I tried uninstalling and then reinstalling ubuntu-gnome-destop and apt-get update, which also did nothing, I also started lightdm which let me login on tty7 but for some reason it was a ubuntu dekstop not gnome, and it too kept restarting. However, after a reboot it wouldnt work either, instead I was confronted with a pop up warning about low graphics settings, but still just a black screen.
Any help would be greatly appreciated.
[edit] While looking around on one of the virtual terminals I noticed a new file in my home folder named "core"
