radeontool --- utility to get/set registers and to control backlight on radeon based laptops


radeontool [option] [command]


This manual page documents briefly the radeontool command.

This manual page was written for the Debian distribution because the original program does not have a manual page.

radeontool is a program that switches on/off backlight and external output on ATI Radeon based laptops, and is able to list or set register values.


You can specify one of the following commands:

dac [on|off]
Power down the external video output
light [on|off]
Power down the backlight
stretch [on|off|vert|horiz|auto|manual]
Adjusts stretching for resolution mismatch
Show a listing of some random registers
regmatch [pattern]
Show registers matching wildcard pattern
regset [pattern] [value]
Set registers matching wildcard pattern


These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below.

Show a little debug info
Skips the first n cards and acts on the n+1
