I was using it with 384.111 and it worked great however on 390.25 , Prime Sync is not working and tearing is awful.
I was using it with these steps.
sudo xed /etc/modprobe.d/zz-nvidia-modeset.conf
options nvidia-XXX_drm modeset=1
At that case XXX is 390.
I check if modeset is on with that command
sudo cat /sys/module/nvidia_drm/parameters/modeset
It says ’ Y ’ as yes.
Finding my output with
After found it , i added this to system startup
"xrandr --output eDP-1-1 --set 'PRIME Synchronization' '1'"
It was working with these config on 384.11.
When i decided to open a topic about it , i saw this.
Generix said there:
After reboot, you can check if it's working with xrandr --prop |grep Sync Should return PRIME Synchronization: 1
It returns as both 0 and 1 to me.
xrandr --prop |grep Sync PRIME Synchronization: 0 PRIME Synchronization: 1
