Hi,
I am part of a team working on a HTPC distribution based on a minimal
Ubuntu installation. Our main focus is viewing and recoding TV via
DVB-C/S/T.
Currently I try to use the TV front end with gnome-shell, this is
working not bad and is looking great. I believe the look & feel
of gnome-shell is perfect for this.
There is only one big problem. If I start the TV front end on my atom
based test machine I get %35 CPU load from gnome-shell only.
Starting another front end like XBMC I get additional %35. The video
decoding is made by the GPU using VDPAU. So the CPU has not much to do,
but this heavy load is too much for the CPU and I get frame drops.
Before gnome-shell I used openbox. Openbox needs less than %1.
What is the reason for this high load? Compositing? Did I make a
configuration fault? Do I have to live with this?
Sorry for my bad English.
Regards
Gerald Dachs
