Backlight Keys stopped working 1.15.6 ->1.16.0 (Sony Vaio, 2011)
With libinput 1.15.6 pressing the backlight or screen brightness buttons worked. On my laptop that is Fn-F5 and Fn-F6. With 1.16.0, these keys no longer work.
Steps to reproduce
I have attached two .yml files, one for event0 (AT Translated Set 2 keyboard) and one for event7 (Sony Vaio Keys). Each file was created with this sequence: volume down, volume up, brightness down, brightness up. The volume works and can be seen in the event0 file. event0 does not show the brightness up or down keypresses. Repeating the test but looking at event7, only the brightness up or down keypresses are seen. Looking at debug_events.txt, I noticed that event7 is being ignored:
event7 - Sony Vaio Keys: is tagged by udev as: Keyboard Joystick event7 - Sony Vaio Keys: device is a joystick, ignoring event7 - not using input device '/dev/input/event7'
event7 has the event codes:
# Event code 224 (KEY_BRIGHTNESSDOWN) # Event code 225 (KEY_BRIGHTNESSUP)
- libinput version: 1.16.0 not working, 1.15.6 working
- hardware information: Sony Vaio VPCEG, 2011 model year.
- libinput record - 2 files attached
- libinput debug-events --verbose` 1 file attached
