Thanks! It worked like a charm ;-)
Now the limit is 480 minutes (8 hours), which I suppose is quite a long
time... ;-)
Cheers.

Is there a good way of doing this temporarily, for instance while
playing back video? Can I do it in python? Right now I'm telling the
backlight to turn on every 8 seconds or so, but even that doesn't really
work (sometimes the display goes dim and then pops back).
I don't want to temporarily change any configuration files in case my
program crashes before it can unset this option.

You need to periodically call osso_display_blanking_pause in libosso

Not sure if there is python binding but it is quite likely.

Ah yes, there is a binding in python. I was using display_state_on
instead of display_blanking_pause, that was my problem.

display light to stay on forever (the maximum allowable time is 30 seconds).
Is there some way to force it on, with some '/dev' juggling ? I would like
to use the tablet to show the text transcription of a conference to hearing
impaired people, so if it gets dark after 30 seconds it would be a
problem... ;-). I can assume the tablet will be fully charged, when the
conference starts...
Thanks everybody for any suggestion.
