Title:
The new (2.6.39+) samsung_laptop kernel module causes serious
backlight flick
@ImMortallity
the update is in Oneiric proposed.
So 3 steps are needed right now:
*activate the proposed repo
*Install new kernel
*deactivate the proposed repo
Or wait until the patched kernel is in the official updates repo.

Hey,
I just installed the new kernel and backlight is working as expected. I just

The patch isn't included in v.3.0.0-14.23. I think best is to wait for
3.0.0-15. You could use the kernel from #55 until new update.

ok thx. Good to see a really annoying bug from 2.6.39 being fixed.
If I have some spare time, I might take another look at the module loading
problem.

I have a good news and a bad news.
Good news:
Backlight changing is for me now working as expected.
Bad News:
Loading the kernel module is changing the backlight when it is loaded
I think the problem is somewhere in the quirk detection. I tried to find
it some time ago and came up with the solutio
sforshee: There is the problem. Take a look at #23. The patch should
patch this problem.
Other possibility is to use my solution from #25 instead of brightness
quirk and #23 patch. This patch is also in vorias ppa.

@all
We should send Greg Kroah-Hartman the patch from #25 (this one is used in the
ppa) as a patch against the vanilla kernel. He is the maintainer. I'm at the
moment too busy.

Is this really a regression? Before 2.6.39 There was no backlight
changing. Since 2.6.39 the samsung-laptop module is activated by default
and we have a backlight changing problem.

The ppa will make testing much easier. good idea!
voria, are you in contact with Greg Kroah-Hartman? Maybe he has some
background infos on Sabi (there isn't any public documentation, is it?).
I think we should also use patch mentioned in #13 because this bug is still
relevant.

I just experienced this problem yesterday, but with upstream kernel (I know

I can confirm that this bug still exists in Kernel 3.0.0-11-generic. The
behaviour is like papukaija said. It is pretty annoying and blacklisting
the module isn't a real workaround, because you won't have any control

I think this bug is related to Bug #807306 or even a duplicate. The workaround

the duplicate.
