    Nvidia forgot the registry key,

    System: Ubuntu 18.04
    graphic card: nvidia 750Ti (-390 driver)

    Last Sunday after booting first on that day, my nvidia graphic card wasn't recognised anymore and also not the monitor. Looking into the graphical part of nvidia settings, I saw that there was no profile listed. When I put in nvidia-settings into the terminal, I got an error message in the terminal, that told me that the registry key could not be found. Lacking the in-depth knowledge, I purged all things nvidia due to advice I got via Mastodon (federated social network) and went back to noveau, the standard driver, for now.

    Making sure I didn't have a hardware problem, I tested my drives and they all came out fine, without any errors. Therefore I conclude that it has to be a software issue. However I need the proprietary driver for some games at some point, so I do wonder if the same happens when I again install the drivers from the packages (additional drivers). Should I just try or wait a few days, as I saw in a German forum that other people had likely problems?

    Re: Nvidia forgot the registry key,

    I'm running 390-* as well, from the repo http://ppa.launchpad.net/graphics-drivers/ppa/ubuntu. No problem here with kernel 5.05 and since a couple of weeks kernel 5.3.18. From where du you install your 390* driver?

    And your not on kernel 5.4.x are you? There seems to be no compatible 390-driver from the repos for kernel 5.4.x yet.

    I'd just try to reinstall from repo (like the one above)

    Foot note: "From the repos" as opposed to nivida .run installation files downloaded directly from Nvidia.

    Re: Nvidia forgot the registry key,

    Ahh, double checked! You should be able to run the 440* driver as your card has a newer chip than my GT610.

    Did you try the 440* driver?

    Err, there is no 440 listed in the additional drivers. Also, the 390 ran fine before without any problems (installed it from there). Why do you think I should try another? Got a link where I can read up what driver goes for which card?

    I have a metapackage - with 435, a binary with 340.107, a metapackage with 430 and a metapackage with 390 - aside from the nouveau that I use right now.

    Re: Nvidia forgot the registry key,

    I've got the 440* listed on 18.04.xx

    Do you have the repo http://ppa.launchpad.net/graphics-drivers/ppa/ubuntu activated?

    Re: Nvidia forgot the registry key,

    I installed my drivers via the additional drivers section, from the repos.

    Your question/post made me search a bit more and I found this: https://askubuntu.com/questions/1204...204640#1204640

    The fellow concludes that the 390 is incompatible with the 5.3. kernel.

    Re: Nvidia forgot the registry key,

    390 works fine here on 5.x kernels. Not on 5.4 kernels yet, I've tested. But that's not the issue.

    I think that you would get the 440 driver available via the repo http://ppa.launchpad.net/graphics-drivers/ppa/ubuntu

    Here's how to add the repo: (a bit down the page)

    Hmmm... I'm very cautious on adding drivers with a ppa. I'd be more likely to add the -435(tested).

    I can see however why you think it might be worth it, as it's the one suggested on the nvidia page:

    I've used that ppa for years. No problem.

    The Additional Drivers tool is brilliant for discoverability but, because it's been so simplified, it doesn't give a lot of feedback if there are any problems.

    It has the handy hardware scanner to identify candidates for likely packages to install but the behind-the-scenes installation is just installing a package through the package manager. Installing the package that you're after through the command line instead will give you useful information on where, if anywhere, the problem lies.
