Backlight?
« on: October 28, 2005, 12:23:40 pm »
I'm puzzled about this still. I've found nothing in the docs about changing the brightness of the backlight, is it actually possible?

I ask as it's very useful to turn it down to save battery, but then back up when you need to use it in brightish light.

also, is there a way to rotate the screen without changing xorg.conf?

Thanks

I'm pretty sure this works in X, not just in the console. Press the button that's immediately right of left-ctl and either 3 or 4 simultaneously to adjust the backlight.

I just tested this:

It works in the console, perfectly, however it doensn't appear to work with X. perhaps that needs fixing?

Thanks

thanks, wsconsctl does work. however it has precisely two values at present


0% and 100%, 100 is full on, 0 is barely useable i find. (this is with the snapshot released yesterday)

is this just me? or does it need work?

the display.brightness attribute on the other hand does appear to work, display.backlight is the aforementioned

i think i'll end up trying a key-binding in X somewhere for one display.brightness+=20% (that's the increment), and one display.brightness-=20%


Thanks barryg, helpful as always.

(if anyone can tell me where in england to get a usb-host cable,then almost all my troubles are over)

Yap, i *think* display.backlight should have been a toggle switch.

Rayto, depends on your window manager and/or keybinding daemon, should be easy though.

Actually the wsconsctl display.brightness increment values give 20% on 1 step values...

i.e. at
60% wsconsctl display.brightness+=1 goes to 80%
40% wsconsctl display.brightness-=1 goes to 20%

These are the values you need to keybind

btw: I have only tried this with xfce4 using the Window Manager command mapping and had to use a Ctrl+3, Ctrl+4 rather than Fn+3, Fn+4 which the Window Manager ignored.. possibly due to the fact that this is a Chording Key for a mouse click? Not sure.
