Public bug reported:
In Lucid, when I press my laptop’s button to enable or disable the
touchpad, I am no longer able to type anything into X without first
going to a non-X controlled virtual terminal and then going back to the
VT running X. Sometimes, even that doesn't work and I have to go to a
VT and reboot the system. On at least two occasions when I have done
this, I have had the following log messages appear in dmesg and
/var/log/kern.log:
Mar 9 10:59:07 fennel kernel: [ 4187.678006] psmouse.c: TouchPad at
isa0060/serio1/input0 lost synchronization, throwing 4 bytes away.
Mar 9 10:59:07 fennel kernel: [ 4187.693983] psmouse.c: resync failed, issuing
reconnect request
Followed by this repeated many, many times:
Mar 9 10:59:13 fennel kernel: [ 4193.493333] i8042.c: Can't write CTR while
closing AUX port.
Mar 9 10:59:13 fennel kernel: [ 4194.315567] i8042.c: Can't reactivate AUX
port.
And then this:
Mar 9 11:30:32 fennel kernel: [ 6072.665172] psmouse.c: Failed to reset mouse
on isa0060/serio1
Mar 9 11:31:16 fennel kernel: [ 6115.694946] input: PS/2 Generic Mouse as
/devices/platform/i8042/serio1/input/input15
Mar 9 11:31:16 fennel kernel: [ 6116.507153] psmouse.c: Failed to enable mouse
on isa0060/serio1
On this occasion, my keyboard CapsLock and NumLock lights were fixed on
(though pressing CapsLock and NumLock would indeed toggle their status,
the lights were just on) and then when I went to reboot the system, both
the CapsLock and NumLock lights started to blink (though, they were not
blinking in the pattern that tends to happen when the kernel panics, it
was an unfamiliar blinking pattern to me). I had to power-cycle the
system in order to bring it back up again.
I do not know if this is a kernel bug, or a bug somewhere in the X11
stack. Therefore I am filing this bug report without a source package
attached. Please feel free to ask for any additional information if it
is needed; I am not sure what other information would be required or
helpful in order to provide troubleshooting for this bug. All I know is
that this makes Lucid extremely difficult to use, as my touchpad needs
to be disabled to be able to type large amounts of text and I can't do
that right now (and the touchpad is very sensitive).
Thanks!
