[ddccontrol-devel] non root i2c communication

[Kai-Uwe B. <ku...@gm...>]

I have monitor here, which supports reading and writing of internal LUTs 
over a small monitor framework[1]. It accesses the montor over i2c 
device nodes. That would be nice to integrate in my graphic card LUT 
viewer[2].

Unfortunedly i2c requires root access on my system. And my understanding 
is that i2c is a security issue to open for normal users. How can my 
application nevertheless get the curves. As well there is interesst 
to do more with this monitor communication channel.

Can this be achieved over DDC/CI as well? What would be needed to make it 
non root read and writeable.

kind regards
