Try these, in order, to see if they fix your issue:
sudo ubuntu-drivers autoinstall
Using Synaptic, search for “nvidia” (without quotes). Toggle the “Installed version” column" to bring up just what you have installed. Post a screenshot of those results, here.
nvidia-prime is the one you installed (or at least what I don’t have on my system. Albeit, I have integrated graphics). Once you remove it, your graphics should go back to what they were.
I’m curious - what was the website where you found this .run file?
Unless @jgordon or @zabadabadoo have other ideas, may be quicker to just do a reinstall of the OS.
@lderry@carmar What about item 3a from your @carmar post 21/25?
Somewhere in there is a link to 32bit and 64bit drivers. I assume as @lderry has Core, 64bit one is appropriate. But is that the one that has been downloaded and tried above?
I am afraid I do not have nvidia graphics to worry about so cannot call on personal experience. Sound not display is my pet gremlin.
I went ahead and reinstalled the OS last night. Time will tell if doing so solved the problem. I put it in a new partition. Technically its a triple boot right now. If it seems to be ok I’ll remove the previous installation and expand the current installation into that space.
The reinstall seems to have worked. It has locked up a few times but not like it was. I did expand the partition as well. set up with Zorin and Windows 7. thanks for the help.
