Comment # 4 on bug 1039756 from Dingzhong Chen

Is another bug report https://bugzilla.gnome.org/show_bug.cgi?id=773371 related
to this���
I have installed both GNOME and iceWM. GNOME was chosen during the system
installation, but iceWM came with it.
So if I try to enable autologin with GNOME on x.org, it behaves like the bug I
mentioned above. Removed iceWM, GDM autologin becomes normal.
