Subject: 2.6.37-rc2 vs. 2.6.36 laptop backlight changes?

Hi,

were there any changes between 2.6.36 and 2.6.37-rc2 that would affect
laptop display backlight control?

I have a Dell Latitude D630 laptop, with Intel on-board graphics

00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960
Integrated Graphics Controller (rev 0c)

used docked in dual-monitor setup. System is openSUSE 11.3, X.Org X
Server 1.8.0

I notice that after logging in, under 2.6.37-rc2, the backlight of the
laptop display is dimmed down. Using the brightness keys can turn it
back up again. Logging out and logging in again, dims it again.

I do not notice this with 2.6.36.

Anything to try to resolve or diagnose this?

best regards
  Patrick
