I have a Kubuntu 18.04 installed and I've been playing around with my Nvidia driver (I confess). By that, I mean that I had Nvidia driver 430 installed and working completely. But then since I could not make Nvidia PRIME work, I uninstalled the driver and reinstalled it. I believe I've done that more than a couple of times (maybe one too many).

Anyways, the last time I installed the driver, it worked just like any time before that. But then after a reboot, the resolution is now locked on something pretty low. After some searching online, I found that it might mean that the driver is not properly loaded. And I need to disable the secure boot. But then, I remembered that I had done this before and in fact each time I boot the system, before grub menu, it says Booting in insecure mode. Still, I followed the instructions on this post but of course, you cannot disable something that is already disabled!

To give you a little bit more information:

$ sudo lshw -c display

Does anyone know how to install my Nvidia driver properly?

  • It is very hard to tell what you broke while "playing" with the driver. Reinstall the system looks the easiest way to solve it. – Pilot6 Aug 26 '19 at 11:44

I found the issue. I'm not sure if it helps with anyone else but it helped me. Apparently, I had switched to my intel driver using the prime-select command. So, all I needed to do was to switch back to nvidia:

sudo prime-select nvidia

But why I still had a video output from my Nvidia card and not my Intel card, is an issue for another post.
