Hello,
I have no experience in linux. I recently installed Manjaro plasma KDE. everything was working fine until I installed updates, after that I am facing screen tearing and freezing even before I could login. I am not able use the system manjaro. I am currently on live USB. please help.
Hello @pradyuman 
I guess it is a driver and xorg problem. Could you provide more information about your gpu?
hello @megavolt.
I am using a lenovo ideapad 320 laptop with integrated graphic.
I have created x.org file in x11. It seemed to work but now when I am not on charging then I am facing the problem. complete tearing and freezing. I forced shutdown then plugged the charging and now it is working again.

ok i guess you mean the “tearfree” option:

Maybe it “screen flickering” and not tearing?

Just add
i915.enable_psr=0
to the kernel parameter to disable it.
hello @megavolt
I couldn’t understand how to add something to kernel parameter. Are you suggesting that I should add “i915.enable_psr=0” into /etc/default/grub?
