Comment 6 for bug 361853

I upgraded to Ubuntu 9.10 and found that this problem came back. It is fixed on my laptop by commenting out the two video quirk entries in the file /usr/share/hal/fdi/information/10freedesktop/20-video-quirk-pm-dell.fdi for the Inspiron 8600. At this point running pm-suspend and pm-hibernate from a terminal window suspended to ram or hibernated to disk with out an issue. In both cases, the computer resumed with no problems what so ever.

However, closing the lid did nothing but blank the screen regardless of the ac plug state. To fix that, I had to add a line to the file /etc/pm/config.d/00sleep_module to explicitly choose the kernel sleep module. This is contrary to the statement in a comment in the file that claims "# The system defaults to "kernel" if this is commented out." After a reboot, everything works as expected and as it was working before the upgrade.
