Hi,
I am new in using arch. I've installed it today and encountered big problem with cpu usage when using gnome 3.
htop shows sometimes that my dual core use 200 % of cpu, especially when I'am moving windows.
I have Toshiba Laptopt with Intel integrated graphic card:
# lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)I have installed drivers:
xf86-video-intel 2.20.8-1

I have the same graphic card and no problem with gnome 3.
Does the problem only occurs while moving windows?
If you have gnome-documents installed there seems to be a bug/feature. When you enter the activities menu gjs-console will have a high cpu usage for ~20 seconds. I deinstalled gnome-documents and everything works fine. See also this thread: https://bbs.archlinux.org/viewtopic.php?id=140726

You need hardware acceleration in order to use Gnome properly. Try disabling the effects.
Anyways, Gnome is a resource hog.

Thanks for repley. I will try to reinstall arch again because probably i did somtething wrong.
dominikb - do you have
lib32-intel-dri installed ?
I think it could be opengl rendring which comsume cpu.
If reinstall fails I ll try turn off effects

SOLVED!
I was starting by
startxand my .xinitrc was
gnome-sessionand it should be
exec ck-launch-session gnome-sessionOffline
Great that you solved it!
Enjoy the light-weight gnome 3! (Sorry, I can't hear the rants about gnome 3 anymore)
I have no clue what ck-launch-session do, other that it is a session manager and has something to do with permissions. So i have changed my .xinitrc to only include gnome-session and there wasn't an increase in CPU usage on my side. Maybe it was a permission problem and our user accounts have different group permissions? But if everything ist working for you now... never mind.
Btw, I do not have installed lib32-intel-dri (I'm using 64bit, as you probably do)

Hello,
this might not be useful at this point but in your "glxinfo | head -n 50" command is written
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x301)
This means that you were running gnome-shell only on your cpu, not using the hardware acceleration of your graphic card. llvmpipe is the component that allow you to use gnome-shell without hardware acceleration and takes a lot of cpu to do all the animations. This is why when you move windows it run to 200% (using fully 2 core of your cpu).
I have a working hardware acceleration and when moving window gnome-shell take up to ~18% cpu.
