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.
