I cant turn on my screen.

I have installed r2modman on Manjaro and it doesnt work due to GPU related conflict, so I decided to play around with my options through Envycontrol, maybe, I thought, it could fix my issue. (Maybe it wont, idk, I posted the problem to r2modman issues on github).

Anyways, now, after booting up the system its just black screen. I want to find out how to boot to CDM so I could reset the Envycontrol options.

What I did through terminal:
sudo envycontrol -s nvidia --dm gdm

Nevermind.
I have booted up Arch installation media, mounted my root Manjaro partition, 'arch-chroot' through Manjaro, 'envycontrol --reset', reboot.
After loading back Manjaro it has shown login screen, videocard is working on Hybrid mode from startup.
