19 I found from Xorg.0.log that X11 wasn't finding an evdev module, even though
20 I had INPUT_DEVICES="evdev" in make.conf. So I added USE=evdev to dev-
21 qt/qtgui* and that created the module, even though kensington@gentoo said it
22 had nothing to do with it.
24 I still get the rapid flickering and general confusion though, which is
25 cured by logging out and in again.
27 * That was the only relevant package to have such a USE flag, according to
28 "equery h -p evdev".
