[acer-picasso] Screen brightness setting in xfce not taken into account, stuck on low luminosity
Describe your issue
What's the expected behaviour?
With postmarketOS installed on https://wiki.postmarketos.org/wiki/Acer_Iconia_Tab_A500_(acer-picasso) (congrats!), I can't get the brightness setting changed.
What's the current behaviour?
Using the power widget, changing from Display brightness, no changes, and when re-openning the setting it's back to low.
