some tips:
- upgrade to version 22.10
you can do this from the gui - open the 'software and updates' app. got to the 'updates' tab. go to the 'notify me of a new ubuntu version' change to 'For any new version' - close. you should get a prompt to upgrade.
- sounded like you were having some video codec issues you can add additional proprietary options if you like
sudo add-apt-repository multiverse
sudo apt update
sudo apt-get install ubuntu-restricted-extras
-Steam make sure you have proton enabled for your entire library.
- steam -> settings -> compatibility -> enable the two options for "enable steam play" - then also use proton experimental from the drop down box below.
Graphic drivers
- depends on your GPU. If you're AMD the open source options are the best. if you want to run the bleeding edge versions you can add the oibaf repository [only for ubuntu derived distros]
sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt update
sudo apt upgrade
- if running nvidia make sure you are running the proprietary drivers
open Software and Updates app
Additional drivers tab
you should see some options there. depending on the age of the gpu i think
using Vortex you can install through the game launcher Lutris (also good for non-steam games). You might need to look that up.
- File manager - can't remember what ubuntu uses but if you are getting no love when you are moving / copying stuff you can always download thunar - in the terminal run sudo thunar - but you can really f your system up if you delete things you shouldnt.
