            Bug ID: 259402
           Summary: x11-servers/xorg-server: stopping X makes system
                    unresponsive
           Product: Ports & Packages
           Version: Latest
          Hardware: Any
                OS: Any

When shutting down a X user session system hangs with black screen not reac=
hing
the shell prompt in tty0. The system is completely inresponsive to keyboard=
 or
mouse events. Black screen with cursor in upper left corner and unmovable
mouse-pointer in the middle.

I now upgraded x11-servers/xorg-server 1.20.11_3,1 -> 1.20.13,1 but the pro=
blem
was there for some weeks before, persisting this upgrade.

Searching for solutions I found others having exactly the same problem too:

There I learned that first switching to tty0 and killing X there at least g=
ives
me a terminal prompt again:

No clues in the xorg logfile.
looking at ps aux after shutdown (via ssh from other box) shows no more
X-related processes.
