Not really. Does it work if you switch to render offload mode?
what’s “render offload mode”…? and how i can i swith to?
If i disable externl moniitor, use laptop internal screen, vsync can archieve to 144Hz
Render offload:
https://download.nvidia.com/XFree86/Linux-x86_64/495.44/README/primerenderoffload.html
Basically, your complete xorg.conf can be replace by a simple
/etc/X11/xorg.conf.d/12-nvidia-prime.conf
Section "OutputClass"
Identifier "nvidia"
MatchDriver "nvidia-drm"
Driver "nvidia"
Option "PrimaryGpu" "true"
EndSection
For render offload, comment out the primarygpu option
Section "OutputClass"
Identifier "nvidia"
MatchDriver "nvidia-drm"
Driver "nvidia"
#Option "PrimaryGpu" "true"
EndSection
external monitors can then be eabled by running
xrandr --setprovideroutputsource NVIDIA-G0 modesetting
and applications be run on the nvidia gpu by prepending
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia
e.g.
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia glxgears
