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):
every attempt at resume
Steps to Reproduce:
Created attachment 240421 [details]
output of /var/log/pm-suspend.log
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.

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
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).
