Marking the bug as found in that version.

(I still have no idea why this would happen.)

Oh, I actually only installed the version from experimental because
reportbug told me to try it. The version in unstable has the same
problem, I'm afraid.

Kind regards,

This is presumably a regression in the gdm3 version in experimental,
or a regression in some related GNOME 3.32 component in experimental
(maybe gnome-session or similar). buster/sid are hopefully unaffected?

codesearch.debian.net doesn't find that string anywhere, and it doesn't
look like the name of an X session, so I'm puzzled too.

Bug#926309: gdm3: gdm-x-session calls Xsession with broken arguments

2019-04-03 Thread Matijs van Zuijlen
Package: gdm3
Version: 3.32.0-1
Severity: normal

Dear maintainer,

Since a couple of weeks, I guess, logging into the GNOME X session from
gdm3 shows a popup with the message:

Xsession: unsupported number of arguments (5); falling back to default 
session.

This message also appears in the logs:

Apr 03 09:26:34 bean /usr/lib/gdm3/gdm-x-session[3709]: /etc/gdm3/Xsession: 
Beginning session setup...
Apr 03 09:26:34 bean /usr/lib/gdm3/gdm-x-session[3709]:

Apr 03 09:26:34 bean /usr/lib/gdm3/gdm-x-session[3709]: Xsession: 
unsupported number of arguments (5); falling back to default session.

I have amended the /etc/X11/Xsession.d/20x11-common_process-args script
to also print the passed arguments, and they are:

GDK_BACKEND based on session type

I'm not sure where to look next ...

Kind regards,
Matijs
