hi.
I upgraded one box to ubuntu 9.10. it works nice (except the boot is slower)
I tried suspend to ram and it worked except when I woke up the pc, the usb wifi key was not working and I had to unplug-replug it to make it work again. I found that by using a file in /etc/pm/config.d with SUSPEND_MODULES="$SUSPEND_MODULES rt73usb".
it worked !
I tested several times and was quite happy it simply worked.
then I tried hibernate. it failed with a black screen after resuming.
and now, suspend to ram does not work anymore. the pc goes to suspend with a flashing led on the box. but when I woke it up, the bios began a normal boot process, instead of waking up straight to the desktop. as if it does not know it is in suspend mode.
so something has been changed and I can't track what.
how could I make suspend to ram work again ? (make it work at resume time)
how could I optionaly make hibernate work too ? (avoid the black screen)
and make the 2 play nice together ?
