Hello,
I digged further, and tracked propagated inputs from
"python-matplotlib". So, it propagates "python-cairo", which in turn
propagates "cairo", and then "glib". Also, no propagated input from
"glib" has an issue with GDM, this is the stop point.
So, basically, if your manifest is:
(specifications->manifest '("glib"))
and you use GDM from a foreign distro (Debian 10 in my case), you cannot
log in.
The only workaround I know of at this point is to add the following
lines to, e.g., ".profile":
unset GI_TYPELIB_PATH
unset XDG_DATA_DIRS
Help would be appreciated at this point.
Regards,
