I like to keep my system as lean as possible. To that end I negate a lot of USE flags in make.conf and package.use. For many years I've been building and running xorg-server with USE="-udev". I do have =sys-fs/eudev-3.2.9 installed. =x11-base/xorg-server-1.20.7 builds quite happily with INPUT_DEVICES="libinput" and USE="-udev". The text console works fine. But after running startx, X comes up and keyboard and mouse are unresponsive; I can't even {CTRL}{ALT}{F1} to a text console. The system is not frozen. I can ssh in from another machine and kill xorg-server, returning to a functional text console. Building xorg-server with USE="udev" solves the problem. The news article https://www.mail-archive.com/gentoo-dev@lists.gentoo.org/msg88809.html mentions in passing that "both evdev and libinput require udev ***DURING RUNTIME***". In my case, at least, eudev at runtime is not sufficient; xorg-server must be built with USE="udev". I know this may look like an edge case, but the ebuild should attempt to avoid building a non-functional xorg-server. Making USE="udev" mandatory appears to solve the problem. Reproducible: Always Steps to Reproduce: 1. "emerge =sys-fs/eudev-3.2.9" with 'USE="-udev"'and 'INPUT_DEVICES="libinput" 2. start up X (in my case with startx) Actual Results: X come up but mouse and keyboard are totally unresponsive.
