I just got a Dell Latitude E7470. Mostly works with the latest Fedora live.
However, attaching an external monitor to the HDMI port hangs the machine. I've been using Linux as my primary machine long enough to know that it smells very much like a driver issue and that the only way I'm going to get it to work is to try a newer kernel. So ...
Are there any vaguely official RPMs for new(er) kernels?
If not, what is the path-of-least-resistance for building a new(er) kernel? I can google as well as anybody but if there's a definitive way, I would appreciate any pointers.
This is where all Fedora kernels are born: http://koji.fedoraproject.org/koji/packageinfo?packageID=8 If you download an rpm, you can install it with dnf -C [kernel package], *providing* that its dependencies are met on your Fedora version.
This is how to compile a kernel from the src.rpm found at the above link. https://fedoraproject.org/wiki/Building_a_custom_kernel
I don't do it that way since I've been doing it for a while, and have learned an alternate way that used to be suggested.
But, that said, are you sure you need to do this? I don't run multiple monitors, but if you give some specifics, it might turn out that someone else can suggest a boot configuration or X configuration adjustment that will work.
