It's about the old amusement xpenguins. (A program showing small
penguins walking on the windows and jumping between them.) As can be
seen in the bug report, it doesn't show anything in e.g. Gnome. From
what I understand this is because Gnome doesn't show the actual X
window. It has a second window covering the entire screen as
background, and this window hides all the penguins.
A first question is if this is indeed correct?
If so, could anyone describe it in more technically correct terms. I
would like to write a warning about the issue in the description of
I would suggest something like:
xpenguins works by drawing on the X root window. This is a cute hack
that might not have the desired effect in modern desktop environments
where the root window is not visible.
But a problem is that "NotShowIn=GNOME;" doesn't seem to have any
effect in the current Gnome version. There is no menu to exclude
xpenguins from, and when I try it seems just as available regardless
of that setting. As you may have guessed I'm not a regular Gnome
user, but that is what I see when I test it.
So a second question is if anyone has any advice on how to best
this? How to best make sure Gnome users don't get fooled to use a
program that do not work in their environment.
How did you determine that NotShowIn=GNOME; doesn't have any effect?
It should work fine to hide xpenguins from the places where
applications are normally listed in GNOME (the shell overview and
