As title says, I’m looking for a way to change how brightness up and down work on my MSI GT72 laptop. The problem is these keys are recognized by the system, the slider goes up and down, but the screen brightness is not increased or reduced at all. By the other hand, xbacklight works perfectly, but opening a console to increase or decrease the brightness is way slower than just pressing the proper keys.
I tried to add a shortcut on Settings App->Keyboard->Shortcuts->Custom Shortcuts; made one called brightness up and assigned ‘xbacklight -inc 10’ and mapped it to the fn+brightness up key, and did the same for brightness down. After doing that xbacklight command wasn’t being executed, just the old behaviour. Then I changed the mapping to ctrl+fn+brightness up/down using the same commands and the brightness successfully went up or down, but it didn’t trigger the brightness slider or the animation on screen when you increase or decrease brightness.
So I was wondering, as the title says, if there’s a way to change the command that is executed when you press fn + brightness up/down to always use xbacklight instead of whatever is actually running (I assume is doing the classic echo value to /sys/class/acpi_video/brightness and such) Is this possible?
