I think the problem should be with this file——/usr/share/gamescope-session-plus/device-quirks.

The file where contains “GPD WIN” says：

"–force-orientation right "

maybe change the text into “–force-orientation normal” could solve this problem.

But this file is a read-only filesystems.

I try to use “sudo mount -o remount,rw” or “sudo chmod a+rw” or “sudo setenforce 0”, all failed.

So now the question becomes how can I modify “device-quirks” which is read-only filesystems?
