Hello, Bruno
Thank you for your answer!
Yes, I use integrated on-chip video (Intel Core i5-2500K CPU) and yes, seems
both kernels use the same modules.
But unhappily from your answer I don't understand what can I do to try to get
working ddccontrol on my system.
If you need some additional in
CCing intel-gfx as it is related to intel GPU driver and might get missed
by intel developers on LKML.
Looking at the linked pastebins ddcontrol seems to make use of the same
i2c/DDC line but getting different results.
Surprising info I see in dmesg, that does apply to both kernels, is
that uvesa
