[ltp] T61 suspend to disk / hibernate with nvidia drivers

[Jimmy Wu]

Hello,

I was just wondering if anyone has suspend-to-disk working with the
non-free nvidia drivers?
For Thinkwiki and other sites I've seen that say this works out of the
box, none of them mention using the nvidia driver, and it seems
everyone is using gnome-power-manager (I have xfce4, not gnome).

More detailed information below:

I have a Thinkpad T61 running Debian Sid / Xfce4, with an NVIDIA
Quadro NVS 140M.  From the package lists, I believe I have uswsusp
installed.   Suspend to ram works beautifully with the sysfs (echo -n
mem > /sys/power/state).  When I try s2disk from within X, the system
goes down fine, but comes up to a few beeps, a black screen, and total
unresponsiveness, other than a hard reboot.  I have tried s2disk from
a tty, even while X was running, and it suspends and resumes back to
the tty fine, but when I switch to the X server with Alt+F7, I get the
unresponsive black screen again, and can't even get back to tty1.
Using the hibernate package script, I get the following output:

Some sites say that to get nvidia to resume properly, add the
POST_VIDEO=false and SAVE_VBE_STATE=false to
/etc/defaults/acpi-support.  I didn't have that file, but I tried
installing acpi-support and making those changes.  That didn't fix the
problem though.

At this point, I am a bit at a loss for where to go next, so any help
would be greatly appreciated.

Thanks in advance!
