Description of problem:
In Fedora8 latest kernel, I cannot use the brightness adjust keys of my Thinkpad
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Grab a Thinkpad T61 or T61p
2. Press Fn+Home or Fn+End
Gnome brightness applet moves, but brightness does not change.
Brightness of the LCD is changed and updated in GNOME brightness applet.
I noticed the ibm-acpi / thinkpad_acpi folks just released a patch which says it
fixes T61 and T61p issues. It is located here:
I would like to know if you plan to port this into the 2.6.23.x kernel in Fedora
8 since it appears all T61 and T61p laptops are affected. Thanks!
to the kernel boot parameters...
