I'm going crazy trying to find a real way to make a Dell Latitude D600
suspend with FC2 and acpi...

When I do echo 1 > /proc/acpi/sleep , X goes away and I get some console
messages like this... ( these are from dmesg because the console
messages go by too fast... )

PM: Preparing system for suspend
Stopping tasks:

tg3: eth0: Link is up at 100 Mbps, full duplex.
tg3: eth0: Flow control is off for TX and off for RX.

And then X comes back up as if nothing has happened!  I tried disabling
DRI and even setting the driver to vesa (neither of which option I like)
and it still happens the same way.

I've found references to a myserious "make x and dri not suck with
radeon" patch, but I can't seem to find it.  I'm hoping to not have to
roll my own kernel because this is for a laptop distribution project --
it's going to find it's way onto ~150 laptops so I'm trying not to have
maintain my own kernel rpms.

Don't have any specific experience with your hardware but you could try
these two things:

1.  Try values of 3 and 5 instead of 1 to echo to /proc/acpi/sleep
   "1" isn't meant to suspend.
2.  Switch to a text console before you use the echo
3.  There have been some problems solved by setting the swappiness
   value to 100 before trying to suspend:
    echo 100 > /proc/sys/vm/swappiness

Please help before I get more keyprint on my forehead from slamming it
against the keyboard.


ouch. :-)

I'm seeing the exact same behavior on my laptop. Using 3 instead of 1 to echo to /proc/acpi/sleep - same thing. Using 5 does nothing.
Would love to see a solution to this.
