-------- Oleksandr Kryvulia writes: > Does backlight(8) works for you? Speaking of backlight(8): On my T14s, I see the following: If I set the light with backlight(8) to something, say 30%, and then change the power-situation, for instance by unplugging the charger, the backlight goes up to 100%. If I then try to set it back to 30% with backlight(8), nothing happens. If I use any other value, for instance 31%, backlight(8) does the job. I guess somewhere some code says "It's always 30%, just return" ? This might be a bit confusing if you have the intensity encoded in some script, which then "sometimes does not work"... -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
