On a different distro, I did a sudo apt update and Nvidia did some patch and now no games work me as well. Linux or the graphic cards compatibility has always been really bad for me. It’s really sad. So unless you pay some developers, opensource platforms will be wobbly/bad :(
I will wipe my distro and try again later :(
This helped me a lot. Install a RSS reader on your Linux, and start following Linux blogs. They explain everything and you will learn about the newest technologies from people who work on Linux
Its Foss - they focus on becoming better Linux/privacy user
OMG Ubuntu!
Fedora Magazine
and many more.
If you see interesting information, look if they have a RSS feed and add them to your list.
You will learn and become knowledgable over time. They will do the effort and try to explain everything, you just have to read what they write
