Description Danielle Madeley 2007-04-08 01:48:35 UTC 
From bug #5665

  obviously it's not adding the acpi pipe as an input handler after (but only
  after) s3, and adding it as a general handler before s3: you've encountered
  another bug.  please open a new one on whichever driver you use, attaching
  xorg.0.log and xorg.conf.

Please list the detailed steps, and attach logs.

Comment 4 Danielle Madeley 2007-08-28 06:44:08 UTC 
Aah, I'd forgotten about filing this. It's still an issue.

To cover the problem again:
In the past (see bug 5665), ACPI events were preventing the LCD backlight from staying off, causing it to wake up when the next ACPI event was received (on a Toshiba, this is about once every 30s). This was then fixed so that it would work up until the laptop entered sleep state S3 (i.e. suspend-to-ram) for the first time, after waking up, the LCD backlight will wake up about 30s after switching off again.

I've attached my xorg.conf and Xorg.log as requested. The log should contain a nice number of suspend/resume cycles.

I can't reproduce this problem on my 915gm.
Comment 6 Danielle Madeley 2007-08-30 02:56:46 UTC 
You need to receive an ACPI event, e.g. 'battery' or 'ac_adapter'. Toshiba laptops like to send lots of these.
Comment 7 Gordon Jin 2007-09-04 22:31:01 UTC 
Yes, I'm seeing 'battery' and 'ac_adapter' event in /var/log/acpid, but I still can't reproduce.

I think we still don't have detailed HW info yet.. What's the model of your laptop? other things like output from lspci and dmesg could be helpful too.. thanks.

General server ACPI issue, not intel driver.

Mass closure: This bug has been untouched for more than six years, and is not obviously still valid. Please file a new report if you continue to experience issues with a current server.
