Comment 7 for bug 1619677

OK, I've just tested on the same system with an older kernel 4.6.0, and it works again using VGA on the same old beamer that didn't work in 4.8.4.

On Fedora 25 beta I used koji to install 4.6:

$ wget https://kojipkgs.fedoraproject.org//packages/kernel/4.6.0/1.fc25/x86_64/kernel-4.6.0-1.fc25.x86_64.rpm https://kojipkgs.fedoraproject.org//packages/kernel/4.6.0/1.fc25/x86_64/kernel-core-4.6.0-1.fc25.x86_64.rpm https://kojipkgs.fedoraproject.org//packages/kernel/4.6.0/1.fc25/x86_64/kernel-modules-4.6.0-1.fc25.x86_64.rpm
$ sudo rpm -ivh --oldpackage ./kernel-4.6.0-1.fc25.x86_64.rpm ./kernel-core-4.6.0-1.fc25.x86_64.rpm ./kernel-modules-4.6.0-1.fc25.x86_64.rpm
