However, the gamma adjustment option tries to run 'tkgamma', which is no longer in Puppy. Forum member 'PANZERKOPF' has come to the rescue and written a little GUI using gtkdialog. I have hacked it somewhat and put it into Woof.
I have implemented it slightly differently. It creates /root/.xgamma-gamma, which is read by /root/.xinitrc
I also fixed the X server chooser Wizard, which offers to use either Xorg or Xvesa, but the latter is not in Quirky.

I am a bit late with commenting, I got here via google ...
xgamma takes values from 0.1 (darkest) over 1.0 (default) to 10 (brightest). Currently the mapping in the script is made from 0 to 200 ( I think 0 is not acceptet by xgamma, although the gui lets one choose such a value).
I have the feeling a logharithmic mapping would be better suited. One could scale from -100 (darkest) over 0 (default) to 100 (brightest) and map that value x to use as input value y for xgamma.
this would exactly reproduce the border values.
Anyway, I have tried to implement this ideas and made a post on the forum
