------- Comment #12 from [EMAIL PROTECTED]  2008-10-25 12:14 -------
Here is my test with 2.6.26.6

1) Before rebooting into 2.6.26.6, I set the brightness to 62%, my preferred
level.

2) After booting into 2.6.26.6, the brightness level does NOT change. 
/sys/class/backlight is an empty directory, and
/proc/acpi/video/VGA/LCD/brightness says the current level is 0%.  There is an
inconsistency.

3) Switching between xorg and console does not change the /proc/.. file, nor
the brightness level.  Everything stays the same.

4) If I echo a value into /proc/acpi.., the brightness will change accordingly,
and the file will now contain the correct value.

5) After echoing the value into /proc/acpi.., switching from xorg to console
does not change the brightness nor the /proc/acpi.. file.  They are still at
the correct values.
