Mine should be a Rage P/M Mobility, therefore not radeon? I am not an expert. I went ahead and downloaded the radeon tool. WHen I just pass the command "radeontool" I get this vaio:/home/ben# radeontool usage: radeontool [options] [command] --debug - show a little debug info --skip=1 - use the second radeon card dac [on|off] - power down the external video outputs (on) light [on|off] - power down the backlight (on) stretch [on|off|vert|horiz|auto|manual] - stretching for resolution mismatch regs - show a listing of some random registers This shows that light is on. So I pass this command "radeontool light off" and then rerun "radeontool" as it is, and get this: vaio:/home/ben# radeontool usage: radeontool [options] [command] --debug - show a little debug info --skip=1 - use the second radeon card dac [on|off] - power down the external video outputs (on) light [on|off] - power down the backlight (off) stretch [on|off|vert|horiz|auto|manual] - stretching for resolution mismatch regs - show a listing of some random register THis shows that light is off, but it isnt as I am typing now, and nothing changed since I ran the radeontool. When I run the same command with debug I get this "radeontool --debug light off" vaio:/home/ben# radeontool --debug light off 0000:00:0d.0 VGA compatible controller: ATI Technologies Inc Rage Mobility P/M (rev 64) (prog-if 00 [VGA]) Subsystem: Sony Corporation: Unknown device 80af Flags: bus master, stepping, medium devsel, latency 66, IRQ 9 Memory at fd000000 (32-bit, non-prefetchable) [size=16M] I/O ports at 1400 [size=256] Memory at fc105000 (32-bit, non-prefetchable) [size=4K] Radeon found.

Can someone explain?
