From 71972c2534d490284d3d42b456c2f34b964b2894 Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom Date: Thu, 2 Sep 2010 10:53:28 +0200 Subject: linux: Don't lose console events on non-evdev drivers (#29969) The drain_console() function will race with new keyboard events being added by the hardware causing the server to lose keyboard events if the console fd is used for input. Only use the drain_console() when AllowEmptyInput is off which is the best indicator we have for whether the keyboard driver will be used. This patch will only fix the bug when hotplugging is disabled. What we really need is a way to figure out either whether we're _not_ using the keyboard driver (not predictable) or a way for the keyboard driver to disable drain_console().
