Switching off the backlight on the console
I'm making use of an IBM Thinkpad X21 as a 3G router. It's running a server install of lucid. The laptop has the cover up a lot of the moment. There is no X, simply a simple console. The colsole spaces itself, yet the LCD backlight is constantly on.
The graphics chip is ATI Technologies Inc Rage Mobility P/M AGP 2x (rev 64).
The adhering to components connected to the framebuffer are currently filled:
$ lsmod | grep fb fbcon 35102 71 tileblit 2031 1 fbcon font 7557 1 fbcon bitblit 4707 1 fbcon vga16fb 11385 1 vgastate 8961 1 vga16fb
Can I make the LCD backlight switch off when the colsole is extra and also have it activate instantly when required?
Not fairly as instantly as you could such as, still releasing the adhering to should certainly transform the illumination right down. More jabbing about in the/ sys tree could disclose various other corresponding actions to improve it :
sudo su -c 'echo "0" > /sys/devices/virtual/backlight/acpi_video0/brightness';
After that make use of the power switches on the key-board to get the illumination back up. Make certain to validate the accuracy of this line w.r.t. just how your/ sys tree looks.
