Every game is freezing in ubuntu

[Ninecrows]

Hello!
I was trying to play dota 2 and the games is freezing randomly. I can move the mouse and the sound keep playing but the screen is freeze. I can't do alt+tab or any command with keyboard, the only option is to force shutdown the notebook. Anyone can help?

given the described behaviour, check if you're getting the RAM totally filled up while gaming

try Kisak Stable PPA for a newer gpu driver if your GPU is Intel or AMD

doublecheck if Steam on Ubuntu is still a normal apt package or became a Snap package (iirc Canonical has been trying to do it for a little while, not sure what's the current status for this)

Such things happen when you use up all your resources.
But root has the usual 5% of resources reserved. So you should be able to log in to root and see what happens.
The easiest way to do this is to press Ctrl+Alt+F3 - but when the system is so dramatically strained, it can take a while, In extreme situations, even a few minutes may pass before the console is displayed.
(You will return to the graphics console by pressing Alt + F7 as usual, but it can also be Alt + F1 or another.)
When you get the login screen, log in to root and you can, for example, check what process is so rude. You will do it with the top command.
It's hard to say more blindly...

edit:
You can log in to root on the text-based console before you experience a lack of resources.
