Hello, It seems that the laptop-mode-tools available in squeeze is not compatible with the last kernel backported. At boot, the following error is printed : " Enabling laptop mode...Unhandled kernel version: 3.2 ('uname -r' = '3.2.0-0.bpo.2-amd64') " Is it possible to backport laptop-mode-tools? Regards. -- ,--.
