In the hardware config screen during installation I changed
the resolution (from 1280x1024 to 1024x768) and then adjusted
the X screen 3 or 4 mousclicks further left. When it was centered
I hit the Save button and then saw a segfault in YaST quickly on
the screen (too quickly to capture it), then the system booted
into the system and is now up in runlevel 5 (reached) but
still in text mode.

System (zert162.suse.de, default PW for root and for "testuser")
is now in this state and can be inspected in my office. Black
computer/kbd/mouse and Vision Master Pro450 Monitor.

Feel free to check or let me know which debug info/logs you need.
This is a regression compared to SUSE Linux 10.1 and SLE 10.
