Ryzen 7 with GTX1660Ti driver problem (black screen before login)

post new info, the tearing can be fixed with prime sync but im not sure how well, if at all it works with amd/nvidia setups.

inxi -Fxxxza
xrandr --prop

also, are you still using the configuration from the post marked as solved?

Yes, I still using the configuration from the post marked as solved.

you can try using xrandr to enable prime sync but im not sure if it works with amd/nvidia hybrid graphics.

xrandr --output eDP-1-1 --set "PRIME Synchronization" 1

then check xrandr --prop to see if prime sync is enabled. if that fails you can see if your display supports variable refresh

xrandr --output eDP-1-1 --set "vrr_capable" 1

check xrandr --prop to see if its enabled

~$ xrandr --prop | grep PRIME
PRIME Synchronization: 0
~$ xrandr --prop | grep vrr_capable
vrr_capable: 1

PRIME Synchronization not working. Changed vrr_capable but problem is not solved :frowning:

i think you and anyone else using an amd/nvidia hybrid bring the issue to nvidia devtalk and see if there is support planned for making prime sync work with the amd card either through modesetting or amdgpu. especially since this setup seems to be getting more and more common
