Ubuntu 25.10 to drop support for GNOME on Xorg

Jean Baptiste Lallement, a member of Canonical's desktop team, has
announced
that Ubuntu will drop support for GNOME on X11 in the 25.10
('Questing Quokka') release set for October. GNOME plans to remove
X11 support in GNOME 49, which is scheduled for September, so
Ubuntu is looking to be proactive:

Ubuntu 25.10 is the last interim release before our next LTS (Ubuntu
26.04). By moving now, we give developers and users a full cycle to
adapt before the next LTS, align with GNOME 49 and reduce
fragmentation while simplifying our support matrix heading into the
LTS.

Fedora decided in
early May to drop X11 support for GNOME in Fedora 43, which
is also due in October.
