Well then, I didn&#x27;t know that about dist-upgrade. But either way, I have used the graphical update tool&#x27;s &quot;A new version of Ubuntu is available&quot;, and it always did a proper upgrade. I assumed the Kubuntu version would do the same (and indeed, it certainly tried).<p>Yup, a GTX 980 Ti. Surely for the installer nomodeset is a sensible default - once the Nvidia drivers are installed it doesn&#x27;t matter, but it&#x27;s tricky to get the drivers without a functioning display.<p>I&#x27;m not actually looking for something for my grandma, of course. And I <i>can</i> usually recover my system when stuff like this happens, as long as I have a different online connection and a few hours to spare. I just hate doing it.
