Much confusion and conflicting information regarding Nvidia driver installation in Ubuntu. In my case Ubuntu-mate. My goal is to use my Linux workstation exclusively for GPU rendering, so installing Nvidia drivers properly is of utmost importance!
All I 've learned so far is
- don't use Nouveau!
- most problems I've encountered are due to improperly installed Nvidia drivers!
The problem with most installation guides is they act as recipes, without actually telling you WHY this is a better approach or WHY you might try an alternative. Ok Rant over :)
A quick google search turns up the following 5 recent (within the past year) installation guides for Nvidia drivers on Ubuntu. A very simple breakdown seems to be between what I would call 'fully manual' methods using the command line (link #3 below) vs some combination of PPA + using the Software & Updates menu.
Question #1 Why PPA, and in what way might this be 'better' than a fully manual install? Link #5 below suggests PPA is untested ( so does that mean beta and possibly avoid?)
Question #2 If using a fully manual install (link #3) should I simply choose the most recent driver version? The reason i ask is in link#1 (official guide?) it says that the actual version
"depends on the version of Ubuntu one is using, and what graphics card one has installed."
Question #3 Is it one way or the other? ie If you install your driver manually should you avoid using the Software & Updates > Other Drivers window to avoid conflicts?
Question #4 If unsure what driver version you have currently installed, how do you properly remove ALL installed graphics drivers to start from scratch?
