Hi Brad,
Thanks for the quick reply, this is my first experience with the debian-user mailing list and it makes for a positive one.
I ran nvidia-detect every now and then and it doesn't tell me exactly which version to install. Instead, it tells me that my card is "OK" (not legacy, GTX-1070 Ti) and that I should simply go and install nvidia-driver. I did that both times, once running from the standard debian repo, which installs version 418, and once also from debian-backports, which installs version 450 (both is OK per Debian wiki
here). Previously this worked fine, but now those processes fail me as well, so something is different this time, I just don't know what.
I am not skilled when it comes to building drivers, can you tell me what to do to make sure I have everything it takes for this to work? It might be something along those lines as last time I had the same problem, it happened after a kernel upgrade. Back then I could fix it by reinstalling, which is not the case now, though.
Thanks,
Vinko
