Hello, I have two computers both performing slowly after the last update.
CPU is cycling & everything is jittery (not smooth). Here are my specs:
Processor : 2x Intel(R) Atom(TM) CPU N270 @ 1.60GHz
Memory : 2063MB (380MB used)
Resolution : 1024x600 pixels
OpenGL Renderer : Mesa DRI Intel(R) 945GME x86/MMX/SSE2
HTOP shows it's the usr/bin/x..... that is consuming the cpu
Can anyone help please?

By "last update" are you referring to the Intel graphics driver package? Also, could you be more specific as to which /usr/bin/x... process is chewing up CPU and how much?

Thanks. Yes it was the graphics drivers.
The process is: usr/bin/x -dpi $DPI :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch
It is consuming 5-12% cpu.

Could you post the output of the following?
Fwiw I get similar cpu usage on my system because it's using "GLX Renderer: Gallium 0.4 on llvmpipe" (software rendering). I have Kabini - Radeon HD 8240 graphics, but they're not supported that well in Wheezy.

That looks right.

boot into init 3 and run sgfxi as root
you might have to do this twice

Worth a try, but usually does not help much with Intel graphics cards.

Is compositing turned on? You might need to turn it off. From Settings -> Windows Manager Tweaks -> Compositor tab.

There was an update in wheezy-backports to the Intel driver to
xserver-xorg-video-intel_2.21.15-2~bpo70+1
If you think this upgrade is causing the problem, and you have rebooted and confirm that the problem persists, you can downgrade to the stock Wheezy version in Synaptic (Force Version) of 2:2.19.0-6 to see if that cures it. Make sure to reboot after the downgrade.
