The Screen Remains Darkened After 'startx'

[Amit Yaron]

Using the fall back widow manager XDM, I've found that the reason why no 
applications with GUI - including the XFCE4 Window Manager can be started.
The culprit was an old version of libfontconfig. The message I got when 
trying to run Firefox from XDM was:

    libpangoft2-1.0.so.0 undefined symbol FcWeightFromOpenTypeDouble

With some help from Dr. DuckDuckGo, I've found that 
FcWeightFromOpenTypeDouble is a symbol in libconfig.so.
And the package that installs the library is named "fontconfig".

I hope to see the library added as a dependency of packages/ports.
I've also opened an issue on https://gitlab.xfce.org
