Sorry forgot the most important part.

Upstream looks dead and I wonder if this will be fixed ever... maybe this should be treecleaned

it is not totally broken, only using the ADL backend. using i2c-dev it works perfectly fine here.

Comment 9 wbrana 2016-08-29 11:18:45 UTC

It works with Intel GPU

Can we keep this, please.
Works with intel G965 and intel GPU here.

Comment 11 Alex Belykh 2016-08-30 21:19:11 UTC

I'm using it fine via i2c on an older radeon too. I can keep using the ebuild via my personal overlay, ofc, but I don't see it hurting anyone as it is now.

Comment 12 Simon 2016-09-01 20:16:07 UTC

I'm using this with nvidia using i2c without problems as well, would appreciate it if this package can be kept in the tree.

Maybe adding a warning on install/emerge about the ADL backend is an option?

Comment 13 Pacho Ramos gentoo-dev

2016-09-17 15:02:31 UTC

Can the ADL backend be disable in some way?

Comment 14 Diogo Pereira 2016-09-18 14:44:15 UTC

--disable-amdadl should do the trick
