How to lighten display - using LXDE

[silverbirch]

In synaptic, in the Search box, enter           gamma             then click the Search button. Take note of the packages xgamma and gammapage. Gammapage is a GUI app, while xgamma is CLI. Gammapage shows the commands as one adjusts the settings, and they are all xgamma commands, so it's safe to say it is a GUI front end for xgamma. I don't know if gammapage pulls in xgamma automatically, but it should. I already had xgamma installed when I installed gammapage to test it just now. It looks to be exactly what you are looking for, as it's DE agnostic.

Thanks that seems to have worked, but not sure if it has held after reboot.  Seems ok.  Thanks for your help.

Did you save the settings? My settings have held through about 20 reboots so far.

I couldn't see a way to save them.  That was using the GUI.
