I have a Dell xps 8700 intel i7, NVIDIA Geforce GTX 745 Ubuntu 14.04 LTS and I can not install the appropriate driver for it.
I tried to do is something like this:
sudo apt-get purge nvidia *; sudo apt-get install nvidia-319-updates-dev
But I can not finish what I have in this process because the mode switch the ctrl + alt + f1. However this is impossible, because the graphics mode would have to act without the driver. It does not work (not even screen is displayed for the radio boxes ubuntu during startup and log off the system).
If I install this driver and later do:
sudo service lightdm stop
and nastepniesh /NVIDIA-Linux-x86_64-319.run (value not remember exactly who more or less) on to install it the screen resolution is 1024x768 and still should have 1680x1050 and it can not even change August in x-nvidia.
I know that Ubuntu is najelpszym and najpolularniejszym system and therefore has the largest base of drivers, but this August steel teeth full-fledged system must have known drivers feed of you could use it fully, so please help get it to work all on tip top and full graphics with hardware acceleration on this card and full resolution 1680x1050 :)
