My acer aspire 515-51-563W is dual-booting with Windows 10 and Ubuntu 18.04.3. I rarely will use windows, as of personal preference. Using Ubuntu, the brightness slider disappeared about a week ago, along with it's input recognition. The internal FN+F6 key does not adjust the brightness. I have an external bluetooth keyboard with an FN+F2 key to adjust brightness, that again, does not work. Any keyboard shortcut I attach to change the brightness in the device settings within the system menu will fail.
Zenity's input method prints this:
Current configuration for the input method:
* Active configuration: missing (normally missing) * Normal automatic choice: ibus (normally ibus or fcitx or uim) * Override rule: * Current override choice: (en_US) * Current automatic choice: ibus * Number of valid choices: 2 (normally 1)The override rule is defined in /etc/default/im-config.The configuration set by im-config is activated by re-starting X.Explicit selection is not required to enable the automatic configuration if the active one is default/auto/cjkv/missing. Available input methods: ibus ximUnless you really need them all, please make sure to install only one input method tool.
I have a System Profiler and Benchmark tool with these shown as the input devices;

I've resorted to adjusting the brightness with the terminal, but with every change made there it needs to be rebooted. I feel as if this is a hardware issue; as the monitor brightness isn't adjustable on my windows partition as well. Any ideas for a fix or resolution to this issue?
