Screen brightness and tint control tray applet

February 01, 2020 — BarryK

I received an email from Mikhail that there is no screen brightness control. Mikhail had previously used fatdog, which does have screen brightness control. I suggested 'xgamma', which controls the colours, however, that is not a very good way to control brightness.

Today did some research. There have been many brightness-control solutions over the years, by mike walsh, fredx181, and others. Here are some relevant URLs:

fredx181 created a GUI for 'redshift' CLI utility (not redshiftgui), however it played havoc with my TV screen.

mike walsh's solution with xrandr and the 'sct' utility, works well. I re-arranged his 1.2 PET to suit my liking, and named it version 1.2.1 (25KB):'s dependencies are 'sct' and 'yad'. The former can be installed via PETget and Easy already has the latter. 

This will be in the next release, as it is very useful.
