Sometimes old projects are back. Made some updates for my utility, which is used to control brightness of a display, connected to the #Thinkpad X220/X230 via the AGAN X230 board (from AliExpress):
- Since I'm using Awesome WM and don't want to write a logic to change brightness on the Lua, I added the --increase-brightness / --decrease-brightness options to change it by one step.
- Add option --percent to display current brightness level not as internal value from board, but as percentage.
- Update man page, add ChangeLog.
For now it is tested under #FreeBSD 14.1-14.3.
