[Solved] Picom screen freezes when using 'glx' backend

I installed Arch Linux yesterday and installed i3 with picom. I have Geforce 1060 graphic card.

Picom works properly with xrender. But when the backend is changed to glx the screen freezes. I can move the mouse and click on buttons but the UI does not update. For example I can type on a terminal but the text is not shown, but when I kill picom the text has been typed. I have used arch linux with graphic card before with glx backend and it was fine. I tried disabling vsync and commenting out refresh-rate in picom configuration file.

Re: [Solved] Picom screen freezes when using 'glx' backend

Your GLX backend is broken because that config doesn't expand the module path properly. Remove that xorg.conf and reboot. If it still doesn't work, enable early KMS: https://wiki.archlinux.org/title/NVIDIA … de_setting

Thanks it worked. I've had two configuration files, xorg.conf and another one in xorg.conf.d/20-nvidia.conf, removed both of them and it is working!
