Public bug reported:
Since upgrading to precise my (PS/2) keyboard just stops working after a
while. This is fatal and all I can do is log out of the desktop session
(or reboot) to get it working again.
This happens every day or two, when I am typing - usually when scrolling
back through xterm output. (shift page-up/page-down)
Some investigation has revealed:
hotplugging the keyboard doesn't change anything - nor does it produce
any output in dmesg or /var/log/Xorg.0.log
I can ssh in and the system is working fine. My mouse still works fine.
plugging in a USB keyboard works fine and allows me to do some
debugging:
switching to console (ctrl-alt-F1) shows that the PS/2 keyboard is
working fine in console mode, so it's only bust in X.
Running xev shows only this when I hit a key on the dead keyboard:
MappingNotify event, serial 36, synthetic NO, window 0x0,
request MappingKeyboard, first_keycode 8, count 248
no keypress events.
My /var/log/Xorg.0.log and /etc/X11/xorg.conf fies are attached.
Relevant info is:
in /etc/X11/xorg.conf:
Section "InputDevice"
# generated from default
Identifier "Keyboard0"
Driver "kbd"
Option "XkbOptions" "ctrl:nocaps"
EndSection

$ sudo evtest /dev/input/by-path/platform-i8042-serio-0-event-kbd
shows all key press and release events on the dead keyboard. So they are
arriving at this level, but the X input device seems to be ignoring them
$dpkg --get-selections | grep xserver
x11-xserver-utils install
xserver-common install
xserver-xorg install
xserver-xorg-core install
xserver-xorg-input-all install
xserver-xorg-input-evdev install
xserver-xorg-input-mouse install
xserver-xorg-input-synaptics install
xserver-xorg-input-vmmouse install
xserver-xorg-input-wacom install
xserver-xorg-video-fbdev install
xserver-xorg-video-intel deinstall
xserver-xorg-video-nouveau install
xserver-xorg-video-openchrome deinstall
xserver-xorg-video-radeon deinstall
xserver-xorg-video-vmware install
So I not really sure how this works but it lokos to me that the kernel-
level evdev stuff is working fine. X ignores the xorg.conf 'kbd' config
(possibly because xserver-xorg-input-kbd is not installed? but then
evdev picks up the device and it works fine for a while, but for some
reason evdev starts ignoring that input device.
This looks like a bug...
