I'm running 13.04 on Asus UL30A

Process: Genuine Intel® CPU U7300 @ 1.30GHz × 2 Graphics: Mobile Intel® GM45 Express Chipset OS type: 64-bit

Everything completely freezes after every other a boot or suspend. No keyboard or mouse. It happens every other time. It freezes, I reboot and it works work. Next time I will reboot, it will freeze again.

This never happened with 12.10.

Any advice on how to fix this?

Comment 4 & 5 on this bug give a suggestion which works for one user:-

"Tim: please test with sna turned on, put this in /etc/X11/xorg.conf:

Section "Device"
 Identifier "intel"
 driver "intel"
 Option "Accelmethod" "sna"


Might be worth a punt?
