Seems we can add paldo to this screen. I only don't know how:

my system monitor does not even display a "System" tab...

They added it since Gnome 2.17.1

We have to edit the file /etc/lsb-release to get it done:

Code	[In neuem Fenster öffnen]
LSB_VERSION="3.0" DISTRIB_ID="paldo" DISTRIB_RELEASE="1.9" DISTRIB_CODENAME="unstable" DISTRIB_DESCRIPTION="Paldo GNU/Linux"

For DISTRIB_CODENAME we can add the actual running branch or we start to do codenames.

Hope it will be fixed in the next release

Thanks for looking into it, fixed now.

Always welcome
