Before even beginning to share the problem, I understand that this issue has been brought up a number of times, on different websites. Literally beaten to death. But unfortunately none of the solution worked for me.
Onto the case in point, I recently installed Fedora 25 (64 bit) on Asus TP300L (planning to get rid of Windows 10 altogether!) and everything is working just fine except for the brightness keys. I just can't get them to work :/
xbacklighthas always been my goto module but it failed on Fedora installations. I get an error saying no matching display found (I cannot remember the exact error though).
I learned about
xrandrusing the same trickry as that of
xbacklight(or rather the other way around) but it seems like
xrandrisn't available in Wayland.
GRUB_CMDLINE_LINUX(grub was saved each time) and added (individually),
acpi_backlight=nonewithout any success.
(I didn't expect this to work since it has more to do with Xorg) Created
/etc/X11/xorg.conf.dwith following content,
Section "Device" Identifier "Intel Graphics" Driver "intel" BusID "PCI:0:2:0" Option "Backlight" "intel_backlight" EndSection
Lastly, I tried to create a custom acpi event and registering the combination of function key and Ctrl but I wasn't able to use
The brightness indicator is working just fine, just the functions don't work. So, I am guessing Fedora is handling brightness behavior just fine, its the keys which are creating trouble.
Disclaimer - I am quite new to Fedora and so it would be great if any commands you share are accompanied by some description. I can 'man' up the rest!
