Do only rotate if tablet mode is active about cinnamon-settings-daemon HOT 1 OPEN

I just tried a patched version on my laptop when I realized that this is not the ideal solution. A more elegant way would be to implement an ACPID listener in another thread, as was done with the onscreen keyboard called "onboard". The famous "acpi_listen" could help here.

This has the advantage that not only Thinkpads would benefit. It also allows another important feature to be implemented: When the display is folded back, thereby turning off tablet mode, the screen should automatically rotate back to the "normal" position. If the display is then rotated to "left-up" or "right-up" and tablet mode is activated afterwards by folding the display, this can be detected and the screen can be rotated automatically. This would not be noticed without ACPID Listener.

What is the default procedure with feature requests here? Do you accept pull requests in general or should one wait for one of you writing like "Yes, we want this implemented but we haven't got any free ressources. Any volunteers?"
