Hi, after a recent update, when I'm trying to set brightness using keyboard, I'm not able to set 100% power of backlight. Additionally at the time of pressing key, brightness is jumping for a second.
Using "tee /sys/class/backlight/acpi_video0/brightness <<< 5" works, additionally tracking journalctl it looks like it's problem with interpretation of key strokes or their manager.
Looking forward for help. Thx.

set brightness using keyboard
And what does "set brightness using keyboard" do? Does it call xbacklight, is it bound to some action of your desktop environment (which?), ...?

Edit. Hmm, I think I created thread in subforum about laptops. Maybe I made a mistake.
