I had a Dell D800 with Nvidia 5200FX and I had to wrestle and fight with it to get suspend to RAM working. It turned out that a properly written ACPI script in /etc/acpi/actions and turning off the kernel's agp support did the job. To suspend, it ONLY works to do the FN-Suspend key. None of the scripts provided for suspending worked--the system or video would not wake up. That includes acpitools, pm-utils, hibernate, and gnome-power-manager (can't tell what it was trying to do to suspend). pm-utils assumes Now I have a new D820 (Nvidia quadro card) with a fresh install of FC5 (and the Nvidia driver), and there is no ACPI script at all. I hit FN-Suspend and the system suspends, and I hit the power button or open and close the lid, andit wakes up! No fuss, no fight. On the other hand, if I use the Gnome menu where it says "suspend", the system goes to sleep, but never wakes up. It appears not to awake the kernel, or lock right away. It is not the "video does not wake up" problem that plagued me on the D800. After all the wrestling with the D800, understand that there are many different suspend scripts and not all are written for any particular video card. But I do not understand 1. Why does FN-Suspend work without any configuration in /etc/acpi 2. What is Gnome doing to try to suspend and how can I make it work like FN-Suspend. -- Paul E.
