[scrarfussi]

i noticed that 11.2 seem sto use alot of processing especially stuff like xorg and plasma this gives me a problem when i am watching videos they tend to freeze n jerk here n there is there any one else with this problem

I don't see this. What processor and Video card? Run Top and see if you have something eating CPU

possibly desktop effects enabled and using indirect rendering instead of the capability of the 3d card

plasma desktop and xorg seem to use alot of cpu on my system
coopstah how do i check which rendering i am using thanx

[coopstah13]

well you can see if you are using the right driver with

glxinfo | grep direct

I'm not familiar with plasma, does it use compiz? If compiz is running you can check how it was started

ps -eaf | grep compiz

if you see --indirect-rendering that is a problem

[scrarfussi]

plasma is what runs the widgets on kde4
glxinfo | grep direct
direct rendering: Yes
