I'm setting up a couple of old machines as sort of web/email kiosks for

I haven't tried in SL6 yet, but in SL5, I place my theme directory in
/usr/share/gdm/themes/<theme_name>/
In there, I have a GdmGreeterTheme.desktop that defines the name,
description, author, and greeter filename.
Then, there is a file matching the greeter filename above (usually
something like theme_name.xml) that contains all the goodies you are
looking for.
It is probably quickest to just clone an existing theme and tweak your
colors/text accordingly.
Look for system-logo-icon.{png,svg} in /usr/share/icons/hicolor or
somewhere similar. I don't remember the details. xfce4 has its own
name, and I think KDE has its own name also. Either that or
computer.png. I don't remember precisely.
Anyway, if you're doing a kiosk by far the easiest way to get what you
want would be to make your own redhat-logos package (and whatever
other theming packages there are) from the original SRPM and either
include an obsoletes line or increase it by a version number you're
sure SL won't overwrite when, say, 6.3 or 6.4 are released.
Also, gnome has a series of icon caches that can trip you up. You can
replace the icons and still see the old ones in central places for
quite some time (and this survives restarting X). To fix this you'll
need to delete the icon-theme.cache files at the base of whatever
system icon theme directory you're replacing icons in (like
/usr/share/icons/gnome/icon-theme.cache) or your changes will appear
to have no effect.
Good luck.
Aha, that was the last piece of the puzzle I needed!
I figured out that the icon being used by running: sudo -u gdm
gconftool-2 --recursive-list /apps/gdm/simple-greeter:
/apps/gdm/simple-greeter:
logo_icon_name = start-here
Using the existing (default) System theme, I found the icons in
/usr/share/icons/System/(various sizes)/places as "start-here.png".
I replaced all of the variously sized icons with my own (keeping the
same name) but nothing changed, even after rebooting. I then deleted the
icon-theme.cache in /usr/share/icons/System, rebooted, and voila!
I'm intrigued by the idea of tweaking the redhat-logos package, as this
will be something that I'll have to do again in the future. I guess I'll
have to do some more reading....
Thanks for the help!
