Title:
Synaptic Touchpad xevents are hijacked under X
Status in xorg package in Ubuntu:
New
Bug description:
Synaptic Touchpad xevents are hijacked under X11.
I have a problem with the synaptic touch-pad on my Acer Aspire that started
around a week ago.
The problem can be described as that there is a massive amount of xevents
being generated and appearing to originate from the touch-pad even though the
touch-pad is not used.
I have tested the HW which seems to work fine.
The test performed is to start a terminal session (Ctrl + Alt + 2) before the
fault occurs and check the xevents by running
~$ sudo evtest /dev/input/eventX
where the X to use is found in /proc/bus/input/devices and found by running
~$ cat /proc/bus/input/devices |grep mouse
No matter how much the touch-pad is used will the console show the
corresponding events which indicates that HW and driver works OK as long it is
not under X
When the problem has occurred (in Desktop mode) is it easy (but inconvenient)
to get back to normal by key combo Fn+F7 twice, turn off touch-pad and then
turn on again.
And more, one can get unlucky in the sense that the generated events could
click somewhere one do not want to click.
During the problem is it impossible to use the mouse since it flies around
(mostly going in a bottom to top of screen direction) but one can check the
generated events using evtest again.
How can I help troubleshooting the problem?
