[Sugar-devel] Screen Reposition?

[Art Hunkins]

Thanks, Gary.

The variable is where you said ~/.Xclients). Changing SUGAR_SCALING to 100 
does make for nice, larger icons and graphics, but as you indicated, no 
larger fonts!

Strangely, the new experimental SoaS issue (v2) does not respond to a change 
to 100 (no larger graphics at all).

Just for fun, I specified a value of 150, and on reboot got faced with the 
blue login screen - with a very large "Login" graphic, and a tiny login box. 
I couldn't get past this screen and needed to reset my computer.

Complete dead end. I'm continuing my work with set_use_markup() - which 
works fine with gtk.Frame and gtk.Label, but I've yet to get to work with 
gtk.Button.
