Further information: the relevant plugin calls xrandr to set screen and
display properties. I have checked xrandr itself on my Intrepid system,
and it works correctly to set the display inverted, normal, left, normal
in sequence.

The bug reported above involves the "new" applet that calls the xrandr
plugin to gnome-settings-daemon; if I select Rotation | Left and click
Apply the display blacks out and does not recover. Subsequent attempts
to login result in failure, retruning me to the login greeter.

I was able to recover from this situation by the following sequence:

login to Failsafe Terminal session;

xrandr --screen 0 -o normal

At this point an attempt to login failed again.

login to Failsafe Terminal session;

xrandr --screen 0 -o normal

gconf-editor [opens as a GUI without window decoration], set
/apps/gnome_settings_daemon/plugins/xrandr/active to OFF;

sudo chmod 755 /   [just in case there is a global permissions problem -
no idea if this is necessary]

exit and login again - success - normal desktop returns.

It seems clear that there is a problem in the applet, rather than the
underlying program xrandr - this seems to work correctly on my system
(HP Pavilion laptop, with AMD64 processor and ATI Radeon Xpress 200M
graphics. Using the OS drivers, not fglrx.)
