Hi

I am not sure that my card is a radeon. 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,

        Memory at fc105000 (32-bit, non-prefetchable) [size=4K]
Radeon found. Base control address is fc105000.
reading RADEON_LVDS_GEN_CNTL (2d0) is 00e8fd3c
writing RADEON_LVDS_GEN_CNTL (2d0) -> 00e8fd3c

It says that "Radeon found", but nothing changes with my backlight. Can
someone explain?

Thanks

Ben
