This question already has an answer here:
I have NVIDIA GTX 970 GPU, which is pretty new chip and it is not recognized by nouveau driver shipped with Ubuntu 14.10, hence I am stuck on 1024x768 resolution on Full HD monitor - not so good. There is no proprietary driver in Additional Drivers setting, so I decided to download and install driver directly from NVIDIA web site.
I tried to install NVIDIA driver exactly like I did ten years ago on Slackware:
$ sudo ./NVIDIA-Linux-x86_64-343.36.run
but it says, that it must be run without X Server running. Ctrl+Alt+F1 (or combination with any other F? key) takes me to the black screen and only thing I can do then is to return back to X by Alt+F7.
My next step was to tune GRUB to boot into pure text mode. I edited
/etc/default/grub to have:
$ sudo update-grub
and reboot, system hangs during boot on some video mode stuff.
My question is: how to run a pure VGA text mode? No famebuffer, no fancy splash, just pure ASCII 80x24 text? I need it only once, just to install NVIDIA driver and have 1920x1080 screen resolution.
I also tried to install NVIDIA driver from Ubuntu repository:
$ sudo apt-get install nvidia-331
No success, it made my system unusable with graphics totally messed up.
