Description peter@prh.myzen.co.uk 2016-09-22 15:26:11 UTC

My /var/log/Xorg.0.log complained that I had no evdev module. I had to add USE=evdev to dev-qt/qtgui and recompile.

This should have been picked up from INPUT_DEVICES="evdev" in make.conf.

dev-qt/qtgui[evdev] doesn't control X evdev drivers, that's normally pulled in via x11-base/xorg-drivers.

Nevertheless, adding USE=evdev to dev-qt/qtgui gave X11 the evdev module it needed, without any other change.

I don't know what "gave X11 the evdev module it needed" means, but note that USE=evdev on qtgui is not normally needed on desktop systems.

It means that, without USE=evdev on qtgui, X11 complained about its evdev module being missing; with it, it doesn't.

And I didn't have it either to start with. I only tried it because "equery h -p evdev" showed only qtgui and a game as having an evdev USE flag.

I've had INPUT_DEVICES="evdev" in make.conf for as long as I can remember - several years, at least. Only now, with plasma-5 and friends, have I found a problem, which I reported here.
