You rece
Mahesh Asolkar, thank you for reporting this bug to Ubuntu. Karmic reached EOL
on April 30, 2011.
See this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases
Is this reproducible in the latest release of Ubuntu via
http://cdimage.ubuntu.com/daily-live/current/ ?
I too have a wonderfull Dell c400 and the info in this bug helped me get
suspend working. Thanks. However, my config of Ubuntu seems a bit
different so the instructions that work for me are listed below. Note
that the splash boot option caused the cosole video to core dump in
combination with nomod
Steps 1, 1b, 3 from comment #26 worked for me. My Dell C400 with Karmic
now activates the display after resuming from suspend. Yes! Thanks
James!
$ lshal | grep -e system.hardware.product -e system.hardware.primary -e
system.hardware.firmware
system.hardware.primary_video.product = 13687 (0x3
Adding "i915.modeset=0" to GRUB_CMDLINE_LINUX_DEFAULT in
/etc/default/grub and running update-grub did it for me on a ThinkPad
X40 as well.
A real fix would be appreciated nevertheless! Thanks a lot!

pm-suspend with quirks does not restore backlight anymore

I followed hedgefighter's solution in #28 (which is really just the
first part of James Keating's solution in comment #26). The addition of
'i915.modeset=0 nomodeset' to my kernel parameters eliminates the no-
backlight-upon-resume problem for me.

Same solution worked for me, thanks.

system.hardware.primary_video.product = 13698 (0x3582) (int)
system.hardware.primary_video.vendor = 32902 (0
I can confirm this bug and the same solution for my Intel 945GM.
I added i915.modeset=0 to the end of my GRUB_CMDLINE_LINUX_DEFAULT in
/etc/default/grub and ran update-grub and suspend and hibernate are
working perfectly again.

I can confirm James' latest workaround works for me on my X40 (although
I changes /etc/default/grub instead).
Thx all that work on this.

Wait -- that's incomplete. Originally I deleted all the non-Intel
sections, and that worked. Looking for a solution easier for others to
follow, I tried just removing the quirks lines, and thought it worked,
but it didn't.
My solution, in short:
1. In /boot/grub/menu.lst
add i915.modeset=0 nomode
Having put a "return 1" at the head of "have_kms()" in "/usr/lib/pm-
utils/sleep.d/98smart-kernel-video" I do get my backlight back after
resume from suspend to RAM.
m...@upsight:~$ lshal | grep -e system.hardware.product -e
system.hardware.primary -e system.firmware
system.firmware.release_dat
Here it's the same. No backlight after resuming. Still stuck to the
workaround...

I disabled KMS as suggested in the release notes (thanks Mike for the
pointer). It did improve CPU utilization during video playback. But
sadly, it did not fix my back-light problem on resume. My laptop still
resumes without back-light.

Ohh just saw your link to this being already an official bug, so it
should be clear that everyone here is missing xv. Hope there will be a
fix for this in karmic some day...

There is another problem with KMS for me. KMS breaks Xv on intel 855GM video
(as in X40 thinkpad).
The fix for that is to disable KMS in GRUB, and that fixes the backlight on
resume problem too.

I tested the patch mentioned in my previous post:
http://bugzilla.kernel.org/attachment.cgi?id=23409
This fixes the problem. As it is a trivial, three lines only patch, it
shouldn't be too hard to get it submitted, right?

For me and my X40 laptop, I use
i915.modeset=0
as kernel command line. This turns off KMS and restores the backlight.
BTW, this (417599) is bug 292256 in a new form. Should they be merged?

I had changed the /usr/lib/hal/scripts/linux/hal-system-power-suspend-
linux file to include the quirks in an effort to make them persistent.
But since you wanted me to try with default files, I reverted my changes
and tried. I still see that the pm-suspend command with command-line
quirks works. L
I ran that command, but it does not work here. The Laptop (x40) starts but then
there is a very dark "_" blinking. But the backlight is on! So this maybe some
other bug?
Some days ago I had the exactly same problems as you did, but now (I think
because of an update) the behavior is different.

@Stephan: I don't see the behavior changed since my last comment (#4).
The pm-suspend command mentioned in the comment works, but is not
persistent.

Does this still work for you?
After an update this does not work any more. Without changing anything (all
defaults), the backlight now works out of the box but the display remains black

Can someone this confirm?

Well, I now see that when I use the following command, it works:
% sudo pm-suspend --quirk-s3-bios --quirk-s3-mode --quirk-dpms-on

The laptop suspends and resumes with backlight ON.
But if I try to make it persistent by adding the quirks to
/usr/lib/
I can confirm that Manuel Siggen's work around works for me too - on top
of the work around I was using until Karmic, as mentioned in the
original bug report.
Is this a bug? Is there a plan to include a fix for that in the near
future?
