#### Please describe your issue:
in some games there is screen tearing, which is a bit annoying, I tried to fix it with xorg.conf but it doesn't work

[TomTravis]

gnome uses chromium heavy it does not work so well with focal try kde and mate or xfce4

[elkawai621]

@TomTravis , I want to install mate, but I don't know how

[TomTravis]

sudo apt install mate (cli) from a xterm in the gnome session

[elkawai621]

@TomTravis I already installed it, I start it? how?

[TomTravis]

nano .xinitrc add pulseaudio --start exec mate-session

save to local account then xinit it will start

[TomTravis]

i use it also

[elkawai621]

epic , Thanks!

[elkawai621]

but is there a way to start mate like this: sudo startmate

is it annoying to run start-chroot | xinit

[TomTravis]

nope unless you make one i just xinit via cli no sudo needed

[TomTravis]

do some reading

[TomTravis]

i do not use start-chroot never have sudo enter-chroot -c /media... xinit

let us know what happens with mate ? I'm starting to use KDE development tools work very well with bullseye, Focal runs well also

The new gnu text editor will not install on Bullseye it want the new kernel and OS bookworm

[elkawai621]

@TomTravis I have been testing mate and it has many problems with vulkan, when playing dolphin emu it said: "failed to create vulkan device", I managed to fix it but is buggy

[elkawai621]

to install it i use: sudo crouton -n mate -t ​​core,xorg,x11,audio -r focal

(it was just that)

[TomTravis]

i do not play games maybe a light weigh WM will be the best for games https://ice-wm.org/

or build it https://dolphin-emu.org/docs/guides/building-dolphin-linux/

[TomTravis]

mate is for ease of use not gaming

[elkawai621]

oh

[TomTravis]

yes compile for the setup helps also game

[TomTravis]

ok ill check out the 3d performance with the games KDE tools also runs somewhat slow loading not super fast xtogo server client is used also
