Subject: xserver-xorg-video-intel: changing to a non-native mode dims backlight
Date: Sat, 16 Oct 2010 22:01:15 +0100
Package: xserver-xorg-video-intel
Version: 2:2.12.0+shadow-2
Severity: normal

Changing video mode to any mode less than my laptop's screen resolution
(1280x800) has the strange side-effect of dimming the backlight to its
minimum. It can be adjusted back up via the hotkeys as usual.

Switching back to 1280x800, or switching between the two available refresh
rates for 1280x800, does not dim the backlight. When in 800x600 (which also
offers two refresh rates), switching refresh rate does not dim the backlight,
but switching to a different low-res mode does.

This is on a Lenovo X200s. I've tried downgrading to xserver-xorg-video-intel
2:2.9.1-4 from testing (with everything else the same), which doesn't
exhibit this bug. However, 2:2.13.0-1 from experimental still has the bug.

Having tried this out in various versions from snapshot.d.o, it seems this
regressed in 2:2.12.0+shadow-1. I've sent appropriate BTS control messages.

It turns out this can be worked around by reverting part of the "+shadow"
series. On the upstream bug, Chris Wilson thinks the correct fix is to improve
backlight setting in the kernel, though.

There is now a different upstream fix for this in master
(commit 33c08882c0d from Keith Packard) which also works for me. I don't know
whether you'd prefer to use that one, or the reversion I suggested.

http://git.debian.org/?p=users/smcv/xserver-xorg-video-intel.git
(the upstream fix applied as a patch instead) certainly works with my current
kernel, which is 2.6.32-27 for amd64.

I'd committed the revert on monday:
http://git.debian.org/?p=pkg-xorg/driver/xserver-xorg-video-intel.git;a=commitdiff;h=2e37d6f4183f695386ded784720870a9598d3825
I don't know of a bug number the initial patch was fixing, so I'd go
with the revert instead of the cherry-pick.

We were waiting for 2.13.0 to move to testing (which has now happened), I
guess we'll upload soonish.  The next upload will also probably disable
shadow on 865G (which is apparently less broken than 845 and 855), and
have some version of
http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=455f2939a661764ebb8d1747d44e16a0a8937808
(I had a simpler patch to do this which just called
pci_device_has_kernel_driver() from intel_pci_probe(); since we're
autoloading i915 from udev we don't need to modprobe it from X.)

Let me know if you'd like to work on getting that ready so I can cross
it out of my todo list ;)

Cheers,
Julien
