What graphics card are you using?

I’ll tell you below.

What is the output of lspci -nnk | grep “Kernel driver in use”

What desktop environment?

LXQt.

What filesystems for your root drive and mounted drive?

ext4.

Is your mounted drive able to be read, written to, and have programs run on it by your regular user account?

Yes. It can. I’ve check it firstly.

I created another one post about this theme: https://lemmings.world/post/28646761

And who knows, maybe it can solve this problem.

I think that this post can be closed.

Thanks to you! 😄
