Default Re: DisplayPort Powersave Help

I'm seeing the same symptoms as dilzz, but am able to get the monitor to wake up if I switch away from vt7 and switch back again using Ctrl-Alt-F1, Ctrl-Alt-F7.

My hardware is an Apple early 2009 Mac mini that is driving an Apple 30" LCD monitor via an Apple DisplayPort to dual DVI adapter.

But for the lack of wake-up on mouse or keyboard activity, everything looks good at 2560x1600.

This hardware is running Debian Lennny 5.0 (stable) with the following nvidia-specific packages:

ii nvidia-glx 185.18.14-2 NVIDIA binary
ii nvidia-kernel-2.6.26-2-amd64 185.18.14-2+2.6.26-17 NVIDIA binary
ii nvidia-kernel-common 20080825+1 NVIDIA binary
ii nvidia-kernel-source 185.18.14-2 NVIDIA binary

Note that nvidia-kernel-2.6.26-2-amd64 is built using module-assistant from nvidia-kernel-source/unstable and that nvidia-glx is also from unstable.

I'm running with the following xorg.conf:

Section "Device"
Identifier "Video"
Driver "nvidia"
BusID "PCI:2:0:0"

grep -i nvidia /var/log/Xorg.0.log:
