Hi, thank you guys for the thread and Kai for the kernel update.

I am currently running Linux 5.9.0-rc4+ I downloaded from
https://people.canonical.com/~khfeng/lp1853277-final/

The touchpad is now working great, but my display is kinda glitchy and laggy. 
And from what I noticed, it is because of the NVIDIA graphic card is not 
working normally.

>UNCLAIMED.

Does anyone have suggestions for the workaround? Thank you.

NB:
I attached two images comparing the one running 5.9.0-rc4+ kernel and 
5.4.0-42-generic.
Device Lenovo Yoga Slim 7 14IIL05, OS Ubuntu 20.04. And I have disabled Secure 
Boot in BIOS.
