Never try to login as the user SDDM

looks a very welcome patch

[jleclanche]

You're hardcoding sddm even though the user/group is customizable by the distro. Risky.

[davidedmundson]

so does PamBackend::start
though maybe that's wrong too, and should be replaced with an explicit --greeter argument.

[plfiorini]

As far as I remember we only accept a user named sddm.

[davidedmundson]

New version uses explicit flag instead of username comparison

[MartinBriza]

I'd leave out blocking the "sddm" user... it could cause only minor problems to folks who already have a regular user called like that... if there are any at all. Not insisting though

[jleclanche]

@MartinBriza That is a broken setup in our regard if they have a user the same as the sddm user.
