Re: [ddccontrol-users] Some problems with start

[Nicolas B. <ni...@bo...>]

Hi,

As far as I can see, at least in ddc-probe-4-out, it seems to work fine
(using direct PCI access, not the I2C devices, but it doesn't matter).

Maybe is it not well documented, but you should be able to read the
contrast value with this command:
# ddccontrol pci:01:00.0-1 -r 0x12
and then write to it using:
# ddccontrol pci:01:00.0-1 -r 0x12 -w X
(where X is a number between 0 and 100)

Have you tried the Gnome tool? To build it, configure ddccontrol with
# ./configure --enable-gnome

Then a new application named gddccontrol should be built in
src/gddccontrol. It is much more user-friendly than the command line
tool.

Best regards,

Nicolas Boichat
