Killing VLC when it won\’t close:
pkill -kill vlc

To get my AMD v4900 graphics card working:

https://wiki.debian.org/AtiHowTo

Follow instructions there to get non-free working, then the part with sudo apt-get install firmware-linux-nonfree libgl1-mesa-dri libglx-mesa0 mesa-vulkan-drivers xserver-xorg-video-all

Getting HandBrake to work with DVD\’s was easy. All you need is to have non-free enabled, then:
sudo apt install libdvd-pkg
sudo apt install handbrake

Make sure to do the part the popup says about the libdvd package (mentioned in my last Linux post).

Finally, if your Dell computer is beeping a ton during the Debian installer, you can\’t figure out why, it seems like it\’s not really connected with anything you\’re doing, and the install seems to be going normally, note that it might actually be another computer on your desk beeping incessantly, and really does have nothing whatsoever to do with the computer you\’re actively working on. :facepalm:
