I use Zorin OS 18 Pro

I reinstall and fix it

When I join a game on Roblox through Sober, there's no problem. But if I close Sober itself and reopen it, whenever I try to join a game, Sober closes on its own. I tried deleting it, and it worked—I was able to join the first time, but after that, the same thing happened again.

Im gonna assume your in X11 windowing. try using the 570 server driver for the 1650 i have one and thats the one that worked best for mine

alr buddy

What is with the other Questions I asked above?

Secure boot is off
nvidia driver i try 590 580 570 same problem i have only zorin os

Did You used the ''Additional Drivers'' Tab in Software & Updates to switch the Drivers?

i use the 570 server one it works fine so basicly the next driver up in that list

Okay, so You used that. I would suggest to uninstall and then install again the Driver over the Terminal and see if that helps.

First type

sudo apt purge nvidia* libnvidia*

to remove all Navidia Stuff. Then type

sudo apt autoremove

to remove File Rests. But please look in the List of the to be deleted Packages before You delete them. Then type

sudo apt install nvidia-driver-580 nvidia-dkms-580

to install the 580 Nvidia Driver. If You want try a different Driver replace the 580 with the Driver Number of the Driver You want try.

before i use 580 i have low fps
what do you think for 550 or 535

You can try these older Drivers to see if You get better FPS. But I've read here that there could be an Issues when installing the 550 Driver. When You use the apt install Command for it, look what Packages are getting installed. It could be that You see the Packages for 580. Please control that.

pls give me command for 565 driver i heve too low fps all game

cuz rn i have like 50 fps in roblox

idk why how can fix lag and my pc same have lag for no reason

565 doesn't exist but when You mean 595, You go the same Steps like written here:

but You replace both 580 in the last Command with 595
