The command linked to uses sudo to get root permissions. This requires the users password, which is what it is asking for (and for sudo to be setup in the right way). You may not have sudo set up that way - I don't, I installed the package rootsh and use the command 'sudo gainroot' to get root permissions. So to run that command, I would run:
msa, if you are interested in trying the next release of cssu (though I have no idea when that might be), it might be better just to use the orientation lock until then - that would solve the problem with the image viewer etc.
I don't know how to revert to the original hildon desktop. I would probably just reflash and restore from backup.
At those *****ing about uninstalling the rotating desktop (and now wanting to downgrade to the stock CSSU one): Uninstall CSSU, whether by reflashing or whatever other method you can dig up.
A better idea for the future - don't install stuff that's new and shiny, AND, an even better idea than that, don't fiddle with settings you don't understand - i.e. someone's complaining about the image viewer not rotating images correctly - hildon-desktop rotation has nothing to do (at least, it shouldn't) with app rotation. If the image viewer and other apps are autorotating, that means you went into the CSSU features configuration app (or manually did this in the theme/system transition.ini files) and turned on forced rotation - which was intentionally put in there for CSSU developing/testing, not for end users.
at those **** about those who are still learning this software shouldn't **** about it either, if they can't give a solution they should **** or go**** themselves
