Proposal: configure devices with their name and their connector

Input devices

Currently input devices are configured with their wlr_input_device.name - but if you have two identical devices, you can't configure them independently:

[backend/libinput/events.c:73] Added Metadot - Das Keyboard Das Keyboard [9456:320]
[backend/libinput/events.c:73] Added Metadot - Das Keyboard Das Keyboard [9456:320]

Unfortunately, inputs devices don't seem to have a serial number - only a friendly name, manufacturer and model.

Proposal: being able to configure them by their connector (retrieved from udev). We could add a char *connector field to wlr_input_device for that.

• Find a way to get the connector name of an input device and expose it
• Allow rootston config to use this to configure input devices

Ouputs

Outputs are always identified by their connector for now: VGA-1, HDMI-1-A... However, if you have for instance two DisplayPort connectors, it can make more sense to configure outputs by their name (just like input devices right now). Also outputs have a serial number which can be used to uniquely identify them (given a valid EDID).

Proposal: being able to configure them by their name (manufacturer, model and serial). The wlr_output currently has a name field used for the connector name - we could rename it to connector and add a serial field (make and model are already here).

• Add a serial field
• Find a better name for the name field
• Allow rootston config to use make, model and serial to configure outputs
