[Pkg-xfce-devel] Bug#765077: lightdm-gtk-greeter: Language selection is broken (again)

[pzs-fs at yandex.ru (Vladimir K)]

Wow!...
Which desktop environment are you using? Try to log in to plain openbox and check locale.
Long story short: lightdm does not set correct locale after all. The only thing it does is some kind of strange GDM emulation. It creates variable $GDM_LANG with the same value as Language= in .dmrc.

On the machine where lightdm seemingly worked, it was not really lightdm. XFCE session pulled locale value from $GDM_LANG and set it to LANG.
If you log in to openbox, or, to exclude any possible distraction, create a plain xterm session, you should see that lightdm does not set correct locale for the session. So the bug is valid.
