I had the problem on a new install. It weas a fresh wheezy + TDE14 install.


On synaptics at least some "informations" are problematic. Actually, three 
packages are (more or less available):

I first looked for kpowersave (that's what I am used to) and found two 
pakackages:

- kpowersave-trinity, requiring HAL (it is sitll there, it installs but does 
not work: I get a greyed out icon in the system tray). Trying to start it 
complained about HAL not being installed

- kpowersave-nohal-trinity, indicated as a dummy package. When I tried to 
install it colored red and said it depended on a package (I think now it was 
tdepowersave, but I am not sure) that was not to be installed.

After reading the list I removed the non-working kpowersave and apt-get 
installed tdepowersave and that works perfectly.

I don't know if the two kpowersave are necessary, but most "old" users being 
used to them they actually work as a trap :)
