Comment 146 for bug 121653

"I've installed the kernel modules and suspend/hibernate does not resume here when POST_VIDEO=false."

Nope, resuming doesn't work for me, either (Bug #84991 is still an issue for me, no matter what's in my /etc/default/acpi-support file). The important thing for the purposes of this bug is that suspend works with a SLAB allocator.

As for actually resuming... sorry, I'm in the same boat as you. Suspend/resume used to work back in Edgy; I'm seriously tempted to go back just for working suspend and resume.

Right now I choose between eye candy (FGLRX + Compiz) or working suspend/resume (RadeonHD); I'm currently in eye candy mode, but who knows what tomorrow will bring?
