Dear Radeon folks,
using radeontool 1.6.2-1.1 from Debian Wheezy/testing [1]
$ sudo radeontool --debug light off Found card 1002:9555 (30000) Radeon found. Base control address is 7f0746826000; base framebuffer address is 7f0735e73000. reading RADEON_LVDS_GEN_CNTL (2d0) is 00000000 writing RADEON_LVDS_GEN_CNTL (2d0) -> 00000000
does not turn off the backlight of the laptop monitor. This is a Lenovo G555 laptop with a ATI Radeon HD 4200 graphic device [2].
Do I need to submit a report to Freedesktop.org’s Bugzilla bug tracking system?
Thanks,
Paul

radeontool doesn't support turning on/off backlights on newer GPUs, and I'm not sure I see any reason for it to do so.
It was originally in radeontool as a hack around lack of drivers.
Dave.

Because it says so in its description.

Interesting. Maybe add to the `--help` text and the manual page which GPUs are supported.
Thanks,
Paul

radeontool should only be used for driver debugging. Using radeontool goes behind the driver's back and touches registers directly. The driver supports display dpms just fine. If you are having a dpms issue, please file a bug.
