Public bug reported:

Binary package hint: xorg

With a dual head setup on an ATI Radeon HD 2400XT (RV610) where one or
both of the displays is rotated (ie portrait), there is a mirror image
of the mouse pointer shown on the 2nd display whenever the mouse is on
the 1st display. Only one pointer is visible when the mouse is on the
2nd display.

The extra phantom mouse pointer can't interact with anything on the 2nd
display.

When only the 2nd display is rotated, the extra pointers appearance and
movement still match the 1st display and have the wrong rotation for the
2nd display.

This problem only appears when using the proprietary fglrx driver, but
that might only be because I can't seem to rotate the displays with the
open source driver.

I don't know if this is relevant, but the AMD Catalyst Control Centre
shows Xinerama as being disabled and erroneously says that it can't be
enabled because it needs multiple displays (?).

Apart from the 2nd pointer, there don't seem to be any other problems -
there are no apparent graphics glitches or performance problems. Compiz
also works OK on both monitors.
