Ubuntu 6.06 Suspend Problem Solved

I've been struggling to get suspend to ram to work on my Inspiron 600m after installing Ubuntu Linux 6.06, aka Dapper Drake. In its default installation state, Dapper would suspend, but wouldn't wake up properly. It appeared to me that the LCD light wasn't being turned on upon wakeup. I poked around the web and found this page.

The specific settings I changed were:

# Uncomment the next line to enable ACPI suspend to RAM
ACPI_SLEEP=true

# Should we save and restore state using the VESA BIOS Extensions?
SAVE_VBE_STATE=false

# Should we attempt to warm-boot the video hardware on resume?
POST_VIDEO=false

# Should we switch the screen off with DPMS on suspend?
USE_DPMS=false

The nVidia part doesn't apply to me, since my laptop has a Radeon 9000 video card, but the suggested changes to /etc/default/acpi-control worked like a charm for me. The laptop suspends and recovers gracefully when the Suspend button is pressed or the lid is closed, just as I told it to do in Power Management.
