Secondary screen always rotated 90 degrees clock- or counterclockwise

[iGadget]

On my HP Pavilion zv6000 with 12.04 beta2 (updated until April 14), the secondary screen (connected to the VGA port) is always rotated 90 degrees clockwise or counterclockwise. No 'Normal' or '180 Degrees' options are available in the 'Rotation' menu of the Display Settings.

When connecting the same external monitor to my HP ProBook 6550b, these options are available and work perfectly.

Would this be a limitation / bug in the Radeon driver?

Thank you for your bug report, that seems similar to bug #983291, does doing the equivalent of what comment #3 in that bug report describe makes it work for you as well?

Just installed Release 12.04 (precise) 32-bit on Toshiba Netbook NB255. When I plugged in my Samsung external monitor 1440x900 display. Changing the resolution doesn't change anything. Only have clockwise or counter clockwise option. No normal option. This also happened in the beta version.
