I have an HP 17" laptop with an ATI graphics card. I'm using Ubuntu 12.04 LTS.

A while ago I noticed that Ubuntu is running in 2D mode and I didn't like that so after some research I stumbled upon this https://askubuntu.com/a/252040/74345 and followed the exact steps to fix things. Everything went fine and I'm using 3D mode now.

However, after the restart I noticed my CPU is significantly hotter. Before the changes I made the temp never passed 50 degrees and after the update it's never getting below 70 degrees -_-.

Is this a known thing? What's happening exactly? At least where do I start my investigation?

Is it possible that it's using the CPU for the animations insdead of the GPU?

Thank you!

This is just how ATI GPUs work; they run hot. You can lower the performance setting to help some though:

sudo -s
echo low > /sys/class/drm/card0/device/power_profile
exit

You can use mid instead of low for a more balanced setting.
