So prime-select intel goes through an elaborate process of removing the nvidia drivers, rebuilding the initramfs image and rebooting, solely to load nouveau so the nvidia card can be turned off.

Unfortunately, this means the nvidia drivers have to be removed.

Instead, the developers swapped to an officially-supported kernel feature, which apparently only works when the nouveau driver is present. Firstly, nvidia-prime in Ubuntu 18.04 does not use bbswitch to power-off the nvidia card when you are in intel-only mode.

How is this different to the standard 18.04 approach? rvice is what removes the nvidia drivers and powers off the card it obviously only runs if you selected intel mode.

The nvidia drivers are always present in the kernel image when you start the machine as a consequence of the standard ubuntu install of the nvidia drivers as long as you have not removed them by standard prime-select intel Therefore, it doesn't need to do much at all if you want nvidia mode nvidia mode is basically the default situation. It never adds nvidia drivers which are missing it assumes they are always in a booting-kernel, and unloads them & turns off the card if you are in intel mode. Killing the display manager is necessary to remove the nvidia drivers.ДЄnd remove or add the nvidia drivers to the running kernel.ДЄnd remove or add the nvidia drivers to the running kernel. The script calls a background service which kills lightdm, takes a few steps to change state, and restarts lightdm. There are virtually no reports of bbswitch not working in ubuntu 18.04 and there are many reports of the new way not working. This version uses bbswitch to disable the nvidia card, which was the standard Ubuntu method until 18.04 The modified version is installed into /usr/local/bin which comes first in the standard path, so it masks the version of the nvidia-prime package It uses a modified version of prime-select. Now go back to your GUI session, or some other virtual terminal, and doДЄnd see what you see in the prime_socket VT How does it work? Swap to a virtual terminal (eg ctrl-alt F4)

If it complains that you are already in nvidia mode, do sudo /usr/bin/prime-select intel and then sudo /usr/bin/prime-select nvidia Still stuck? You probably don't have the nvidia drivers installed in your kernel image, which can happen even if think you have the nvidia modules installed, because the standard 18.04 optimus logic uninstalls the drivers when you choose intel mode.

Sudo apt purge nvidia-prime sudo apt install nvidia-primeДЄnd to revert to gdm3, install and select it as the default:Д«ut you will have to work out why the rvice did not do its job. Purge and reinstall the package nvidia-prime You could rename /usr/local/bin/prime-select to /usr/local/bin/prime-select-fast so that the standard script is no longer masked by the modified one.

The first time you use sudo prime-select nvidia to change, you may get an error about a missing fileДo: sudo touch /usr/share/X11//nfДЄnd repeat sudo prime-select nvidia Prime sync for tear free laptop panel This will be true if you have installed the standard Ubuntu nvidia-drivers but it will not be true if you did the standard prime-select intel. You must have the nvidia drivers installed in your initramfs. Ubuntu 18.04 (might work with other distros of similar age which are based on the vendor-neutral library approach, if you change some paths)Д«bswitch (via sudo apt install bbswitch-dkms) Make sure you have the nvidia drivers running before proceeding. They are installed by the standard Ubuntu module, but if you did the standard 18.04 prime-select intel, they are no longer installed in the kernel. This code assumes the nvidia drivers are installed. If you are reading this after installing the fast prime-select (this module), then you access the standard prime-select via /usr/bin/prime-select To ensure that nvidia drivers are installed in your initramfs. If you have done this already, make sure you do

properly install the nvidia drivers the standard ubuntu way, from Additional Drivers.

Install from apt: sudo apt install rustc cargo To install it, you need to know about git clone and you need to be able to change your display manager to lightdm. If things go wrong, you need to know about virtual consoles and recovery mode and some basic systemd admin. However, it also takes advantage of recent improvements, so you can swap modes without rebooting.

Why does this exist? It restores the pre-18.04 'bbswitch' approach it's much faster to change profiles and more reliable.
