Hi,
A quick follow-up on this: It's a general problem with ACPI triggers,
I think. Suspend on lid close is also no longer working. Can't believe
I didn't think to check this before emailing out - sorry.

Hi all,
This morning I encountered serious problems with using my backlight in
X in Testing. There are two related problems:
1. The fn keys on my Thinkpad X200s no longer control the backlight
when X is running.
2. The brightness continually stays at minimum. I can manually change
the backlight by echoing appropriate values into
/sys/class/backlight/intel_backlight/backlight. However, within
seconds the backlight returns to the minimum brightness. Also, with
triggers I can't determine yet, the backlight sometimes flickers from
minimum to maximum before settling on minimum.
However:
Backlight control with fn keys works as normal while in BIOS, while in
Grub, while in initramfs (waiting for me to type my crypto password),
and during boot even after the framebuffer has loaded. Once X has
started, however, they no longer work, and my brightness, no matter
what it was beforehand, drops to minimum, and I can no longer change
it with the fn keys in X or a virtual terminal.
I've attached what I believe to be the only relevant portion of my
log, the last five days of updates, although I only noticed the
problem this morning (and it's very noticeable). I've also attached a
list of packages.
I would file a bug report but I have no idea what package is causing
this problem. laptop-mode-tools is installed but claims to be
deactivated (due to being plugged in).
Any help would be appreciated. Even if the fn-keys stop working for
some reason, if there's some way to figure out how to keep it from
staying on minimum brightness, that would be fabulous.
Daniel
