Nvidia 840m – Fix Driver Problems with Kubuntu 14.10

driverskubuntunvidia

I'm having some trouble installing the 346 driver on Kubuntu 14.10. After I followed this tutorial and after I reboot the system (without anything saying that I must do that after installation), It gives me a black screen in the moment I have to write the password and login. Although I did wrote the password, pressed return and started, but another problem was with the DSL connection.

It wasn't working any more so please can I get some help? I'm a beginner in linux and sorry for my bad english.

Xorg-edgers not always guarantee what you expect. You might have to remove it. Do the following:

sudo add-apt-repository remove ppa:xorg-edgers/ppa

or with ppa-purge (it has to be installed)

sudo ppa-purge ppa:xorg-edgers/ppa

if you can't get to desktop or tty terminal see the link below how to drop to root shell.

And after that other solution is Bumblebee:

sudo add-apt-repository ppa:bumblebee/stable

sudo apt-get update

sudo apt-get install bumblebee bumblebee-nvidia primus linux-headers-generic
