Greetings,

 I have disabled power saving features in linaro ubuntu 11.10 on a
PandaBoard, in order to prevent the screen going black, since there is no
mouse nor keyboard attached to the board (It is simply displaying videos,
in a closed loop). But when I reboot (Or power up after a time with the
board off) sometimes this works, and sometimes not. There seems not to be
any kind of rule for it to work, it can fail 5 or 6 times (going black
after 10 minutes, even when it is set to "never"), and later work ok for 3
or 4 reboots. And then, fail again.

 Can anyone enlighten me a bit? Sorry for the joke, but my brain is almost
as dark as black the screen goes...

thanks in advance,
