I finally gave up on getting my Fn+up/down keys to change my screen brightness on my laptop. I took a brightnessup.sh and brightnessdown.sh script and put them in /etc/acpi and then went to keyboard shortcuts to and assigned the scripts to Ctrl+up and Ctrl+down and finally after months was able to change my brightness with my keyboard. But no sooner did I get it working, I restarted my computer and it no longer works.
Can anybody tell me how to get this working again?
In terminal sudo /etc/acpi/brightnessup.sh and sudo /etc/acpi/brightnessdown.sh changes the brightness so I know the script works but it is not running with the assigned keys.
