I'm also running Edgy and have the same problem. The help text for Users settings says:
" Users list Shows the available users. depending on the gconf key "/apps/gnome-system-tools/users/show_all" it will show the system users too. " however, when I ran gconf-editor, I found it had an entry named "showall" (with no underscore). I tried enabling this setting but it made no difference. I added a new entry named "show_all" and it seems to work... sometimes! There's something not quite right about this, but I am at a loss to explain the inconsistent results I am seeing. -- [users-admin] Can't list all groups, 'lp' group not available https://launchpad.net/bugs/74984 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
