Thank-you for the help; I ran
and attempted
which failed so I rebooted the system and tried again which failed printing the same error message: "Fatal Server Error: No Screen Found" It also said "failed to load NV: this driver cannot operate until it has been unloaded" and something about it being 'claimed by the kernel' or something, so it doesn't seem to be reverting back to the NV driver successfully. Any more help would be great, my n00bishness thwarting me; also, haven't tried downloading/installing binary nvidia driver, will try that- how would I do that from the console? I'm not familiar with Slack, sorry
