Description of problem: I have a Dell Lattitude D620 with an Nvidia card. I'm running Fc8t3 updated to latest development. First of all suspend has disappeared from the power applet. There is still pm-suspend which seems to suspend the machine fine. However, upon resume the machine is active but the screen is blank. I can ssh into the machine, but cannot get the screen active. When I kill the X session the system hangs. I can't find anything relevant in the logs. I'm using the "nv" driver. Suspend used to work fine up until about 5 days ago. So much has been changing I can't tell if it was a kernel, pm-utils, or X change. Version-Release number of selected component (if applicable): kernel 2.6.23.1-35.fc8 pm-utils-0.99.4-6.fc8 How reproducible: every attempt at resume Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:

I tried "setenforce 0" and I tried stopping X first. Still blank screen. Also when I stopped X and suspend/resume then I couldn't ssh into the system either.
Did suspend/resume *ever* work on your system in rawhide? We've disabled suspend on machines with nvidia video because of bugs in the nv driver that prevent it from resuming properly. For details, see here: http://katzj.livejournal.com/407566.html
Actually, suspend/resume is very reliable on my D620 using the NV driver. It was the nvidia driver that always gave me problems. I have recently found out that I need to add ALLOW_NV_SUSPEND="yes" to a file in /etc/pm/config.d to reenable suspend for nv graphics. I've done this and suspend/resume works again. The confusing thing is that without this special kung-fu move, pm-suspend does do a suspend, but doesn't resume properly. Shouldn't pm-suspend be disabled too with some kind of warning message?

Afaik pm-suspend is not intended to be run directly except for testing purposes. echo 'ALLOW_NV_SUSPEND="yes"' >> /etc/pm/config.d/00-allow-nv-suspend help you?
Oh, my comment #5 was incomplete. The "help you?" should read "Does this help you?".
This bug cannot be fixed without having more information (see comment #5).
