Laptop screen stays black on resume from suspend

Hello,

I'm running Debian Squeeze on a Dell Studio 1558 laptop, and I have my laptop set to suspend when my lid is closed. Resuming from suspend seems to work but the screen remains blank, forcing me to hard reboot every time. Upon reading this thread: http://forums.debian.net/viewtopic.php?f=5&t=59618, I checked /var/log/pm-suspend.log, and found this:

Code:

The previously mentioned thread suggested moving the 99video script out of the way to a new directory. I did so, and my laptop did resume the next time I tried suspending, but it seems very unstable. It won't always resume correctly, and upon resume gnome will often be slow, and sometimes things like audio won't work correctly. I definitely don't feel comfortable leaving my configuration this way. Considering that the log tells us exactly what's wrong (can't get a file descriptor referring to the console), I was hoping for some more direct solutions. Any help would be appreciated.

Suspend/Resume is controlled by scripts, and one of the tasks that the Resume script must perform is to turn the display back on. Unfortunately that can be very hardware-dependent. My experience has been that many distro package writers really don't deal with this very well ... and, having said that, I acknowledge that it is a rather intractable problem.
