Hi all,
I am using vanilla-source-3.6-rc6, mesa, xf86-video-ati, libdrm live versions and xorg-server-1.13.0, as desktop environment I am using lxsession with compiz as window manager and I have always used "startx" to startup my desktop environment.
In my opinion my cpu at idle is too much loaded, let me explain.
At idle, no other application is loaded except lxpanel, pcmanfm and conky, I can see from conky that the load on my dual core is divided in 4-7% and 18-24% at 1GHz (lowest state).
This is not a big problem because all is very smooth using all my application and all compiz effect are damm smooth.
But this load at idle has been always present since I used gnome 3 (last 2 years) and now with compiz.
I never worried about this but now I want to know why at idle it should load so much my cpu because I noted that on my father's laptop (i7-720QM, ~amd64) all 8 core are loaded between 0-1% at 933MHz.
This get me crazy.

According to top:

Code:
1773 root      20   0 52284  24m 6468 S  22,6  0,8  64:59.34 X                                                                           
 1890 vasco     20   0 90060 5200 3312 S   2,7  0,2   6:50.52 conky                                                                       
20476 vasco     20   0 81300  24m  13m S   1,0  0,8   0:00.99 terminator                                                                 
 1803 vasco     20   0 86540  23m  16m S   0,7  0,8  12:56.45 compiz                                                                     
20571 vasco     20   0  4840 1460 1088 R   0,7  0,0   0:00.15 top         


So X seems to be the gulty.

Any ideas?

Thanks

I can't see any obvious cause from what you've listed, running powertop might be useful though.

Does the problem happen also if you don't use OpenGL compositing?

If it goes away, you could try to disable low-impact fallback in driconf.

Ok the problem is conky.
If I start my session lxsession+compiz or fluxbox (no compositing) without conky from top all process included X is <1%, as soon as I start conky X bumo to 20%.

This is my conky config file>

I have installed ati open driver on my laptop and X load my cpu of 20% at idle.
As soon as I kill conky X cpu load go to 0.5%
So I think that the problem is ati open driver.

Any ideas?

Hi.

I Think it's because execi is run every second, more than once in your conky config, try to change it to 2 or 5 seconds

Thanks for reply.
I changed all execi to 5 seconds, except the last 3 to 300-600, but same result.

Hi,

did you change window theme or/and taskbar size? It may seem weird at first, but give it a try. My i7 have behaved very laggy until
I switched to another theme. Also try to switch to binary gpu drivers (fglrx for radeon, nvidia for nvidia (not nv nor noveau!)

On my laptop I had fglrx driver = no problem, as soon as I installed ati-drivers X cpu load to 20%.
Same problem with fluxbox and compiz standalone.

I thought fglrx = ati-drivers. You cannot use fglrx option in make.conf without installing binary driver. If you want to use these binary drivers, disable everything connected with ati graphic cards in kernel, put fglrx in make.conf and re-emerge ati-drivers and everything else. But i don't know if I understood what you mean.

Correct me if I'm wrong. I'm quite new to gentoo :)

Let me clarify: I have on my laptop a conky config file similar to my desktop machine.
Until 4 days ago I was using ati-drivers, they worked quite good, and I have had not problem on cpu load on idle with conky running.
Then I switched to open ati drivers because of some libreoffice problem, but I get high cpu load by X when conky is running, if I kill conky cpu load go to 0%.
On my desktop I have always run open ati drivers and when I run conky I have always this high cpu load.
So this bring me to think that there is wrong in open drivers.
