Bug#681830: gdm3: spawns X continuously when gnome-session dies

[Sébastien Villemot]

Control: tags -1 + patch

First, I verified that the bug is not present in vanilla GDM3. It is
introduced by the patches about transient displays and switch_on_finish
property.

More precisely, the problem is introduced by
21_static_display_purge.patch. In the "finish" method of
GdmStaticDisplay, this patch adds a call to the "finish" method of the
parent. The latter parent method changes the status of the display to
the FINISHED state, which in turn triggers a reset of the number of
failures and spawns a new display. The problem is that the FINISHED
state is reached before the FAILED state.

I could verify that the attached patch fixes the problem. And it is
rather clear that the patch does not affect the behavior when the X
server does not fail.

joss: Are you ok with this patch? Moreover, do you think it should be
added as a separate quilt patch, or merged into
21_static_display_purge.patch?
