I just updated to latest stable kernel release (3.2.0-24.38) and I still have the problem.
I then started back on oneiric kernel (3.0.0-19.33) and I did not have the problem anymore.
On recent kernel, every time I close/open the laptop lid, X is frozen. I need to reboot or restart lightdm from console.
I'm running precise on an HP 6730b with an "Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)" which is a GM45.
In the Xorg.0.log I can find these errors every time I have the problem:
[ 145.274] (WW) intel(0): flip queue failed: Invalid argument
[ 145.274] (WW) intel(0): Page flip failed: Invalid argument
