My MATLAB program was crashing every day, so MathWorks suggested I update my NVIDIA driver according to this link:
Linux X64 (AMD64/EM64T) Display Driver
I exited out of GUI mode using Alt-Ctrl-F1
The first time I ran the installer, I was instructed to close my X Server.
I was able to close my x server using the command
sudo service lightdm stop
I ran the NVIDIA installer twice.
The first time I was conservative with the options and selected the “no” option a few times.
The installation failed.
So I ran it again and selected the "yes"option on everything.
After that, my computer got trashed.
All I have now is a low res 40x25 CGA display that continuously reboots.
Is there a way to recover?
