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 :/Solutions tried:xbacklight has 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 xrandr using the same trickry as that of xbacklight (or rather the other way around) but it seems like xrandr isn't available in Wayland.Tried editing GRUB_CMDLINE_LINUX (grub was saved each time) and added (individually), acpi_backlight=vendoracpi_backlight=videoacpi_backlight=nativeacpi_backlight=acpi_backlight=none without any success.(I didn't expect this to work since it has more to do with Xorg) Created 20-intel.conf under /etc/X11/xorg.conf.d with following content,Section Device        Identifier  Intel Graphics        Driver      intel        BusID       PCI:0:2:0        Option      Backlight       intel_backlightEndSectionLastly, I tried to create a custom acpi event and registering the combination of function key and Ctrl but I wasn't able to use acpi_listen.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!System Info: Asus TP300L (Model), No dedicated graphics card, Kernel 4.8.16
