Comment 15 for bug 150109

If you're on 855(GM?) hardware and want Compiz (or anything with textures) to resume ok, you might need to be running a patched version of the -intel driver.

http://www2.eng.cam.ac.uk/~pcjc2/ubuntu/xserver-xorg-video-intel_2.1.1-0ubuntu10~pcjc2.2_i386.deb

This encorporates all other unreleased fixes I've been working on, and an additional line which aims to reset the 3D state of the card after VT switch. This may help after suspend, and has been reported to help issues with textures on 855 hardware after remove.

Please let me know if this helps.
