I'm using an IBM Thinkpad X21 as a 3G router. It's running a server install of lucid. The laptop has the lid up most of the time. There is no X, just a plain console. The colsole blanks itself, but the LCD backlight is always on.
The graphics chip is ATI Technologies Inc Rage Mobility P/M AGP 2x (rev 64).
The following modules related to the framebuffer are now loaded:
$ 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 turn off when the colsole is unused and have it turn on automatically when needed?
