Unknown extension block
EDID block does NOT conform to EDID 1.3!
Missing name descriptor
Missing monitor ranges
Detailed block string not properly terminated
EDID block does not conform at all!
Has 128 nonconformant extension block(s)
I did attempt to modify the patch, and I don't think I did it correctly
Around line 232, I changed
IS_SC7180_TARGET(c->hw.hwversion))
to
IS_SC7180_TARGET(c->hw.hwversion) ||
IS_SDM845_TARGET(c->hw.hwversion))
But it would seem that only gets us 1/2 way there...
https://dev.gentoo.org/~steev/files/image2.jpg
But should I continue on this path, or should we be finding others who
have an N61 and see what their EDID reports?
I have another c630, but unfortunately, it appears to have the IVO
screen in it, instead of another N61. I asked another user and he also
had the IVO.
