[Bug 1517048] Re: External monitors are not detected

 

Christopher, I tested now with the following kernels (between 4.2.6 and
4.3.0)

linux-image-4.3.0-040300-generic_4.3.0-040300.201511020949_amd64.deb
linux-image-4.3.0-040300rc1-generic_4.3.0-040300rc1.201509160642_amd64.deb
linux-image-4.3.0-040300rc2-generic_4.3.0-040300rc2.201509201830_amd64.deb
linux-image-4.3.0-040300rc3-generic_4.3.0-040300rc3.201509271225_amd64.deb
linux-image-4.3.0-040300rc4-generic_4.3.0-040300rc4.201510041330_amd64.deb
linux-image-4.3.0-040300rc5-generic_4.3.0-040300rc5.201510111530_amd64.deb
linux-image-4.3.0-040300rc6-generic_4.3.0-040300rc6.201510182030_amd64.deb
linux-image-4.3.0-040300rc7-generic_4.3.0-040300rc7.201510260712_amd64.deb

And works fine with everyone.

So installing the kernels published in http://kernel.ubuntu.com/~kernel-
ppa/mainline/?C=N;O=D from v4.2-wily to v4.3-wily only works fine with
kernels 4.3*

Tell me if you need  I should test with many other versions.
