Dear all, after a while of not seing updates in OpenELEC I realized many of the developers forked into LibreELEC, so I switched here.
First of all I would really like to congratulate you on the project and sustained support for all of us users.
As I mentioned, I came from OpenELEC system, and I have noticed since the last upgrades, initially to OpenELEC beta and Milhouse builds and lately to LibreELEC 7.0.2 that the brightness control built in on my ThinkPad T440p notebook does not work. I have tested it in both v7.0.2 and LibreELEC (Krypton) v7.90.002 ALPHA.
I have alse replicated this same issue in another T450.
Some notes and troubleshooting I have already done:
* Tried the system that came from the upgrade (severals) and also a clean fresh install. Same beahviour.
* If I set the brightness before Kodi loads, it works, but upon load it goes to full brightness.
Usually it is activated via Fn + F6/F5, to no avail. It looks like it is a kernel issue (or a keymap issue). I am using both Kali and Xubuntu on the same machine, and on both distros brightness operates flawlessly.
Quick search on the web shows many results related to this same issue in different Linux Flavours.
Attached are links for dmesg, kodi.log and backlight information (below)
kodi.log output (in debug mode):
Latest keypresses reflect key to change brightness, apparently keys are not recognized.
Your help or troubleshooting guidance will be appreciated.
Edit 1: installed System Tools Addon and using getscancodes the system does not seem to recognize the brightness adjust keys.
It may be related to the latest update to the .hwdb syntax.
