I recently installed a fresh installation of Ubuntu, and downloaded some Nvidia drivers via nvidia-driver-390. I noticed that nvidia-340 was also installed (as a "binary driver" instead of a "driver metapackage"). Interesting. Later, I installed nvidia-driver-396. I'd like to remove versions 340 and 390, so I can only use 396. I have used
sudo apt remove --purge nvidia-340 nvidia-390 and also uninstalled some of the related packages (
nvidia-kernel-common*, etc.) At this point, I'm just trying to remove every trace of Nvidia drivers from my system and start fresh. Unfortunately, in the included "Software and Updates", drivers 340, 390, and 396 are still listed. A screenshot is attached. Thanks for your help.
