Issue/Bug Description:
After an update, the NVIDIA GTX 1650 Ti in my HP Spectre eb000 seems as if it is no longer being used even in nvidia-only mode, resulting in choppy rendering of the desktop on my external monitor while the laptop lid is closed. It's as if the laptop is still in hybrid mode - nvidia-smi shows gpu utilization of 0%. In settings under the About tab, grapics are shown as "Mesa Intel® UHD Graphics (CML GT2) / Mesa Intel® UHD Graphics (CML GT2)".

I'm not sure if this was caused by updating the nvidia drivers or something else, but the last version of the nvidia drivers that I recall working were 525.85.05. I updated to 530 to see if that might have fixed the issue, but it seems to not have.

Expected behavior:
nvidia GPU is used exclusively for rendering, smoother animations and mouse movement on external monitor.

Other Notes:
I am using a Wayland session.

After rolling back to a snapshot from before the suspected updates went through to test, I realized that Wayland also seems to have had that issue before and that the "smooth" performance I noticed was probably a result of me using Xorg without realizing it. I'm editing the name of the bug to better reflect what I now see to be the issue.
