Backlight doesn't stay off on Inspiron 6400n

[Bruce Cowan]

Binary package hint: linux-source-2.6.22

When closing the lid of the Inspiron 6400n, the backlight goes off. However, after 2 seconds, the display comes back on.

This is with Gutsy, Feisty used to work.

Hi Bruce,

I assume this is still an issue in the official 7.10 Gutsy Gibbon release (kernel 2.6.22-14)? I'll retarget this bug towards the upcoming Hardy kernel and have tagged it as "hardy-kernel-candidate". However against the linux-source-2.6.22 package this is being marked as "Won't Fix" as it does not meet the criteria for a stable release update. To learn more about the stable release update process please refer to https://wiki.ubuntu.com/StableReleaseUpdates . Thanks!

Indeed it is still a problem as of final Gutsy.

Thanks for responding.

Hardy Heron Alpha2 was recently released. It contains an updated version of the kernel. You can download and try the new Hardy Heron Alpha2 release from http://cdimage.ubuntu.com/releases/hardy/alpha-2/ . You should be able to then test the new kernel via the LiveCD. If you can, please verify if this bug still exists or not and report back your results. General information regarding the release can also be found here: http://www.ubuntu.com/testing/hardy/alpha2 . Thanks!

Hardy Alpha 2 doesn't solve it, I'll try to get some useful debugging information.

acpid log from Gutsy.

Seems to work now.

Mine still doesn't. Same problem with Gutsy and Hardy, and now Intrepid.

I hit the forums last week but received no response, so it's probably time to bump this bug.

[Bruce Cowan (bruce89-deactivatedaccount)]

Indeed, it sometimes works, and sometimes doesn't.

...says something about the 'i810 driver' handling monitor off. That could be my problem, but I can't see anything in xorg.conf about the i810 driver and don't know where to look.

Is that likely? Or is this a genuine bug that remains unfixed?

Unfortunately it seems this bug is still an issue. Can you confirm this issue exists with the most recent Jaunty Jackalope 9.04 release - http://www.ubuntu.com/news/ubuntu-9.04-desktop . Please let us know your results. Thanks.

[Bruce Cowan (bruce89-deactivatedaccount)]

I'm afraid I won't help, but someone else will.
