I am typing this from a Libretto U105 running the Ubuntu Edgy i386 Live CD. I am only just familiarizing myself with this machine, but I already accidentally found that at least once, the Fn+F5 screen cycling key would seem to fix the problem. (Cycle through external and external+LCD and back to LCD only: doesn't matter if you actually have an external screen).
Just a quick note lest I forget (have nowhere else to save this information :-) but I'll try to follow up with more details if this seems to work out in the long term. /* era */ -- If this were a real .signature, it would suck less.
