Red Hat Bugzilla – Bug 423991
M6300 Back light does not go out when lid is closed
Last modified: 2016-04-18 05:46:43 EDT
Description of problem:
Running RHEL5.1 x86_64, the Dell Precision Mobile M6300 backlight stays on when
the lid is closed. It needs to go out and stay out to pass certification.
Power up the M6300, close the lid and observe the light by peering through the
slit between the keyboard and the top.
Back light stays on when lid is closed.
Back light should turn off and stay off to conserve battery power until lid is
Verify BIOS is latest before debugging (believe 01).
Dell has found that with the addition of "xset dpms on/off" directive, the
binary nVidia driver will turn off the backlight when the lid is closed. Thus,
it would appear as though the issue is in the nv and vesa xorg drivers. As a
result, I am re-assigning this bugzilla.

The bug is in the g-p-m component, but I'm not the engineer for that. Reassigning.
Acking it based on the fact that Richard proposed a solution further up:
"We can add a call into g-p-m to do the xset (it's there in later versions)"
Can I close this bug as a dupe of https://bugzilla.redhat.com/show_bug.cgi?id=423931 ?
Marking as duplicate, as discussed further up
