Recently you may have seen this topic on Tombuntu’s blog, but if you missed it here is an outline of how to enable the advanced permissions dialog in the Nautilus file manager.
Activating the Advanced Permissions Dialog in Nautilus
Activating (or deactivating) the advanced permissions dialog can be done by way of a single command. To activate the dialog use the command:
gconftool-2 --type bool --set /apps/nautilus/preferences/show_advanced_permissions True
To deactivate the dialog and revert to the default settings, use the command:
gconftool-2 --type bool --set /apps/nautilus/preferences/show_advanced_permissions False
Do you prefer one over the other? The more advanced dialog reminds me of old permission dialogs in FTP clients I remember. I think I may prefer it, but I haven’t used it long enough to decide.
