Ohh! Pretty pictures!

My Lenovo 300 N100 is causing problems again. When I press Fn-F7 to switch output video modes the output is like below on the laptop TFT, blinking from red to pale blue:

Ohh! Pretty pictures!

The analogue VGA output does sort-of work, when set to 1024×768 (rather than a widescreen mode) but I can never get the TFT display back to normal, even with repeated Fn-F7's.

Anyone seen this before? I've tried the latest nv and nouveau DDX. Needless to say, this has never worked on Linux for me, and always worked with Windows XP.

Thanks.
