The PWgui is a bit outdated (new version is under preparation, though).

To trick the gui, define the ::pwscf::settings(CHDENS) variable in your
~/.pwgui/pwgui.settings (if you don't have this directory/file, create

Then add this line into the file:

set ::pwscf::settings(CHDENS) echo

Otherwise, you may save the prepared file by pwgui, and run manually.
