Hi,
on my Sony VAIO VGN-B1VP this is still an issue. Switching to VT does
not help, the backlight stays off.

Works a treat here.
Thanks very much for all your hard work.
Will this be added to the 'production' kernel?

I pulled together most of the described patches. Only the one called
Fix vblank enable/disable callbacks I left out since the dependencies
are quite complicated. I placed a test kernel at:

Could someone please give that a try and report the results? Thanks.

Yes it will. This might be in alpha5 but I am not sure here. But for

Big thanks. It works now. But i found some new issues.
1. It seems that screen could not get blank for powersaving.
2. I get back problem with hd clicking. And it`s much more important than
suspend to ram problem, so i think there is some where in kernel

I had a look at the proposed patches from freedesktop.org and the Hardy

substantially after the 2.6.24 kernel, so this would mean a huge effort

Do you really want to ship Hardy in a state where no laptop with Intel
graphics can suspend and resume? I can see your point about rebasing to
post-2.6.24 code, but in this case why not roll back to a previous,
known-working kernel?

I don't think rolling the kernel back would help anything. The fix for 2.6.25
changes suspend/resume support of the kernel that wasn't there before. But I
could be wrong there.
However, if I read the initial issue correctly, suspend/resume works but the

Ok, I will take a look at those. Hopefully there isn't too much change
outside the driver itself.

Hi,
I have to say that for a few days now the backlight off/blank screen
problem in Hardy doesn't appear after resuming from suspend (I think it
was after the last kernel change). Now there is something different
going on...
I've always had a problem where the blank screen after x minutes

Oh, you're quite right, my apologies.
There should now be enough information in the bug for the kernel team to

Continually setting this bug to incomplete seems like a useless buck-
passing maneuver to me. The fix is released upstream. It's in
freedesktop.org git master in mesa/drm, and it's in Linux 2.6.25-rc1 and
2.6.25-rc2. Why not just import the fix instead of suggesting silly
workarounds?

Hi Guys,
From the upstream kernel bugzilla report:
http://bugzilla.kernel.org/show_bug.cgi?id=9827
Len posted this comment Please try the s2ram application, as it has a number
of workarounds for this issue built into it.
If s2ram doesn't know about this laptop, you can try the workarounds
Hmm, an interesting read. I've tried these fixes already though.
Unfortunately none of them worked for me.
Was nice to learn a little more about them though.

Confirmed on my X61. There was an upstream commit that should have fixed
this, and I once tried the git master version which worked fine. Maybe
some commit is missing still.
