Support for LVDS laptop screens

I have an old laptop with LVDS screen, so when I use the program with the closed lid it doesn't count this state.

To enable lid detection we need:

  1. Name of the display: hardcoded to ""eDP.*"
  2. State of the lid: looks for /proc/acpi/button/lid/.*/state

1 Name

We can add configuration for name as per the wayland version of this tool way-displays: LAPTOP_DISPLAY_PREFIX: 'eDP

What's the name of the display e.g.

:; ./xlayoutdisplay
eDP1 active 31cm/17cm 2560x1440+0+0 60Hz
*+ 2560x1440 60Hz
  !2560x1440 60Hz
...

2 State

Is there a state file for your lid? I see:

:; find /proc/acpi/button/lid
/proc/acpi/button/lid
/proc/acpi/button/lid/LID
/proc/acpi/button/lid/LID/state
:; cat /proc/acpi/button/lid/LID/state
state:      open
