compiz-fusion uses more CPU (~20%), than in gutsy with the same config

[Byron]

Binary package hint: compiz

In Gutsy, I used compiz with satisfaction. Was smart, fast, and beautiful.
In Hardy, seems like it uses more CPU (15-20% instead of the usual 1-2%). Not the compiz.real process is the CPU-hungry, the Xorg itself (according to the top).
I tried all the configurable plugins removing in ccsm, but my sytem is still slow.
glxinfo said nothing special, Direct rendering is yes.
The only way to work with my Ubuntu is the metacity --replace command.

Oh. Important, I upgraded to Hardy, not a clear install.

[Travis Watkins (amaranth)]

Is that while sitting idle? Compiz should use basically zero CPU when you're not doing anything with the computer.

[Byron (byron-impulzus)]

Yes. Unfortunately with the clear install, this problem still occures.
With some Google work, I realized, that this is my problem, only with my precious laptop (1.4GHz Celeron, Intel i915 video card-shared memory)

This report ist possibly a duplicate of bug #177492. Could you please test it with the Intel driver mentioned in this report?

[Byron (byron-impulzus)]

Not the driver install, but the xorg.conf and /etc/environment hacking solved this problem.
Now it's better than in Gutsy :)

[unggnu (unggnu)]

Closing but could you please post what you have changed and which driver you have installed?

xorg.conf:

Section Device
       .
       . # I put the following three lines into it:
       Option "AccelMethod" "exa"
       Option "MigrationHeuristic" "greedy"
       Option "ExaNoComposite" "false"

Then to the /etc/environment file:

INTEL_BATCH="1"

And reboot.
