I only just noticed this after popping the plasma cpu monitoring applet onto my desktop so I'm not sure how long it has been going on, but my X process runs continuously with a high utilisation, almost pegging one of my 2 cpu cores. After starting my X session, things appear to be normal and it's only after a while that this starts happening ( perhaps after starting certain apps? ). I've done some digging around and one of the options for NVidia users is to add:
Option "RenderAccel" "on"
Option "UseEvents" "on
to xorg.conf. This has helped a bit but not by much. If I switch my compositing type from OpenGL to xrender, things don't change much for utilisation ( things slow down a lot! ).
I've also read on the GSB site that there is a problem with high cpu and X with X.org 1.4.2 in 12.2 and they offer a patched version
. I'm wondering if this problem is still in X.org 1.6.3 in -current? I'm also not sure if this problem was there before adding gsb to my installation.
I currently have:
nvidia 7300gt with 185.18.29 driver
athlon x2 5000+
-current up to date
I've attached some top output files:
1. no ffox or tbird
2. just tbird
3. tbird and ffox
I can't recall X ever running this high especially under 12.2/kde 3.5.x. Any help appreciated ...
