I fixed the Username and host to read "trisquel". The fixes will appear in my
next release.
For anyone who wants them sooner, the varibles that control the live user
session are in "/etc/casper.conf" If you want to see these changes you will
need to repackage the ISO by following the instructions in the link on Post
#4.
Regarding your offer, do you know where the attribute for the background
color for the menus is stored? I looked for it a few days ago, but could not
find it. If you could, I would be much obliged if you could tell me where it
is. Regarding theming in general, I like the idea of having a
Trisquel-mate-desktop package that would handle the "Trisquel Look" aspect of
things. If you know about how to build packages and have the time, packaging
the Trisquel 4 theme for MATE might also be useful.
Your offer of assistance is greatly appreciated!
