It would be good, cause on my laptop LCD's highligting lamp is=20 automatically adjust after AC or battery is used. On this laptop i had not manual control over it (i had on old Toshiba=20 Tecra 550) and that hurts. Default AC brigtness is far too high :-( As well, while on AC i'd prefer to see fancy screensaver, on battery i'd = prefer to have waste no CPU/GPU power (no screensaver app) and turn LCD o= ff. I don't know of CRT's brightness has big impact on power consumption. Of course gamma, color maps and similar funcitons belongs to X, but=20 hardware, like a lamp behind LCD might be as well controlled by kernel. --===============96419502021323389== Content-Type: text/plain; charset="iso-8859-1" MIME-Version: 1.0 Content-Transfer-Encoding: quoted-printable Content-Disposition: inline --===============96419502021323389==--
