Suspend/Resume Problems
 
I have downloaded the latest nvidia driver NVIDIA-Linux-x86-1.0-4496-pkg2.run, installed it without problems, updated my XF86Config file, etc. I'm running Red Hat 9.0, using the latest updated kernel supplied by RedHat -- Linux version 2.4.20-20.9. I'm using a Dell Latitude computer with a GeForce 4 video card.

The problem that I'm having is that when I try to resume from sleep after suspending my laptop, all that comes back to me is a blank screen. The hard drive starts up, the fan kicks in, etc., but no X. The only option left to me is a hard reboot (unless I "happen" to have my cursor in a terminal window and I can blindly type "sudo init 6" and my password to reboot gracefully). This means that everything is restored properly except X. Killing X with Ctrl-Backspace doesn't do anything to help either.

I've noticed that I can suspend and resume properly if X isn't running when I first suspend the laptop...anyone know what the problem is?

I've tried looking for this in the forums, but couldn't find a subject about this.

Thanks ahead of time!

Oh, and this wasn't a problem with the old "nv" driver originally supplied with RedHat.

Since I travel back and forth between work all the time and frequently suspend/resume the laptop, I would *really* like to get this problem fixed without having exit X every time I need to suspend. The blank screen after a resume is painfully annoying to have to deal with...

Sadly, power management and nVIdia's drivers don't get along very well. As much as I hate to ask this of a laptop user, try disableing ACPI and APM in the kernel and/or in your BIOS and see if that resolves the issue.

Is this *the* only solution?

I'm actually thinking that it is the backlight that isn't turning back on properly, since everything else is.

Also, it seems that I can't have any USB ports hooked up for the resume to work properly as well.

This kind of sucks---the "nvidia" driver provides so much additional functionality (especially driving LCD screens), but the "nv" driver "works". Have there been no patches to solve this problem??

I found a solution to the problem! Don't have time to fully figure out why it works, but I've verified that it does!

Under Mandrake 9.2 the same solution can be achieved using

PCMCIA_RESTART="yes"

in /etc/syconfig/suspend (note the variable is wrongly spelled RESTART_PCMCIA in the file provided by Mandrake).

It is an interesting twist (and somewhat of a pain as a user) that this works flawless with driver version 4496, but with 5336 I manually have to change to a virtual console before suspending. (Including the change in the script causes all kinds of troubles)
