I want to control NVIDIA booting.
I had a lot of issues with NVIDIA and it is almost the reason of any linux-devil but i also need to run dual screens and Nouveau does not work out of the box and only the proprietary drivers work (unlike Manjaro, open-source drivers work out of the box).
The most important reason i want to block it from working is that it consumes 75% of my battery consumption alone ...
Almost solved - Please help!

I am facing networking issue when kernel updated on my 20.04 LTS from 5.8.0-63 to 5.11.0-25. All worked fine in 5.8.0-63. After update, the wifi networking is not available at all. I am running a VMWare installation with a tp-link wifi usb stick.
I tried steps from here.
sudo apt install linux-modules-extra-5.11.0-25-generic
sudo apt install --reinstall linux-generic.
sudo modprobe iwlwifi
Right now it works with kernel 5.8 but in 5.11 (installed this morning along other upgrades) the wifi adapter doesn't get detected at all and apparently there are no fixes until the drivers gets patched (unless i'm mistaken). Do someone know if/when
bcmwl-kernel-source will get patched?

The only way I could get the computer to turn off was to physically press the shutdown or restart button on my tower. Has anyone else experienced this odd behaviour? I wonder if it ...
