Recently I installed OBS in my system but when i started recording the screen it started flickering .
I have tried this stack overflow solution..
but after doing this and restarting it stucks in booting and doesn't boots up.
Any help?
p.s. - I have tried nearly each solution present in the forums.
Did you see
Also, try using Xfce or Gnome. KDE sometimes have screen recording issue with particular hardware, especially laptop.
We cannot help without system info.
Restore a working snapshot.
Screen flickering does not exist on an unbootable system 
We should know what to not suggest, so explain what you have tried already.
