Bug#485465: CMOS NVRAM and EC do not agree on display brightness level

[jidanni@jidanni.org]

OK, thanks. Now using workaround:
$ tail /etc/X11/xdm/Xsetup
#Every time I start X Windows something turns my brightness to the
#max, and I have to whack it back down by hitting Fn End. Nothing
#tampers with the Linux console brightness, just the X Windows
#brightness here on my Thinkpad r50e.
#xrandr --output LVDS --set BACKLIGHT 0 #or
#echo 0 > /sys/class/backlight/thinkpad_screen/brightness
#often just gets e.g., thinkpad_acpi:
#CMOS NVRAM (7) and EC (3) do not agree on display brightness level
#However this seems to work:
f=/proc/acpi/ibm/brightness
if test -f $f
then
    echo level 0 > $f
    logger jidanni whacking backlight back down in $0
