Dear Maintainer, After upgrading xorg from 7.7+9 to 7.7+12, I've also dropped by the same bug.
Ordinarily, I start the X server through the startx command line utility. Before the server is started, the keyboard works flawlessly. After it's started, however, both the integrated keyboard and touchpad become irresponsive. Therefore, I'm even unable to change tty in order to kill the server. I've tried to downgrade xorg to jessie, through apt pinning, but the problem remained. As a fallback, I've tried to use the startxfce4 script, however, it's unable to start the server and spats up the following errors: [ 2832.743] X.Org X Server 1.17.2 Release Date: 2015-06-16 [ 2832.749] X Protocol Version 11, Revision 0 [ 2832.751] Build Operating System: Linux 3.16.0-4-amd64 i686 Debian [ 2832.754] Current Operating System: Linux xxxxxx 4.2.0-1-686-pae #1 SMP Debian 4.2.3-2 (2015-10-14) i686 [ 2832.754] Kernel command line: BOOT_IMAGE=/vmlinuz-4.2.0-1-686-pae root=/dev/mapper/root-rootfs ro quiet [ 2832.758] Build Date: 08 October 2015 10:05:01AM [ 2832.761] xorg-server 2:1.17.2-3 (http://www.debian.org/support) [ 2832.763] Current version of pixman: 0.33.2 [ 2832.768] Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.
