Giving mythfrontend a higher priority

I use mythfrontend on one monitor in a dual monitor setup and am wondering
how to give it a higher priority/lower nice level as I usually am working on
a doc/surfing/whatever on the other monitor and sometimes the task causes
playback in mythfrontend to stutter/pause briefly (definitely not common but
happens).

Thanks
Bob

You could just "renice" it - something like:

sudo renice -20 `pidof mythfrontend`

but you'd have to do it each time you started mythfrontend.

I'm sure there is also an option in the setup screens like "enable real
time priority" - but you have to do some additional config to get this to
work. I think it's fairly simple and you just have to set mythfrontend to
run with elevated privilidges (setuid??). I've never tried it, but thats
probably your best option.

Robert.

You could also create a launcher/shortcut for 'gksudo nice -n -10
mythfrontend' which should do the trick.

cheers,

You can also give MythTV realtime priority - see

Ahh, I missed that option. Just set it and can see an improvement. Will also
edit my shortcuts to mess with nice levels.

Thanks everyone
