I just updated to latest Ubuntu 12.04 pre-release and the combination ATI 5450
together with BenQ LCD monitor doesn't work any better than before.
The system is still running with the kernel.org 3.3-rc3+ kernel from git.

I wonder what kind of information would help in figuring out why this
particular combination doesn't wake up from standby ?


Below is some info & logs about the current configuration.
