A little bit of an obscure problem, but where is the database for the developer options stored in a Lineage OS filesystem?
I accidentally created an emulated display that was using the android desktop mode beta options enabled, on a raspberry pi. It trapped the mouse on the emulated display, so I literally can't even unlock the "tablet" or do anything else.
@Linux_in_a_Bit there are system settings .xml files. i can't remember the proper path, but find / -name "system*.xml" or "*device*.xml" or similar should yield something?
