Description Niall Sheridan 2008-04-09 08:36:54 EDT
Description of problem:

When I wake my laptop from suspend, the screen is always completely dark. I can
blindly reboot the machine, and if I squint and hold the machine up to the light
I can make out a gnome-screensaver password dialog.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Put laptop into suspend
2. Wake up
3. Darkness
Actual results:
An almost impossible to see screen that won't respond to brightness controls.

Expected results:
A screen I can see things on.

Additional info:
I've found that the following makes my laptop behave when putting it to
sleep/waking it up:

[root@particle ~]# cat /etc/pm/config.d/config

The information which quirks should be applied is stored in hal-info.

Please follow:
to submit your findings upstream, but please post before this the output of
lshal | egrep

And what is also important is: How do you put your machine into suspend? (Do you
call pm-suspend directly, use gnome-power-manager or something similiar?)
Comment 2 Niall Sheridan 2008-04-09 15:11:45 EDT
I tried using pm-suspend and g-p-m and observed identical behaviour with both.
'pm-suspend --quirk-s3-bios' comes out of sleep just fine, while 'pm-suspend'
does not.

$ lshal | egrep \
  system.firmware.version = '7NET25WW (1.06 )'  (string)
  system.hardware.product = '7668CTO'  (string)
  system.hardware.vendor = 'LENOVO'  (string)
  system.hardware.version = 'ThinkPad X61s'  (string)

So it looks like
/usr/share/hal/fdi/information/10freedesktop/20-video-quirk-pm-lenovo.fdi is
missing '7668' from the list of keys to match in system.hardware.product. In
fact, a glance through the hal-info gitweb shows that this was added a few days ago:

Testing locally, adding 7668 to 20-video-quirk-pm-lenovo.fdi makes both g-p-m
and pm-suspend behave exactly as I'd like them to. Any chance of merging
upstream's additions for F9?

Changing version to '9' as part of upcoming Fedora 9 GA.

This was fixed for me by hal-info-20080508-1.fc9
