Public bug reported:
My Dell Inspiron 6400 laptop has a Synaptics touchpad. If I'm using
xserver-xorg-input-synaptics and I use Control-Alt-Fkey or sudo chvt to
switch to a text virtual console and then switch back to X, the mouse
stops moving via the touchpad. The touchpad seems totally ignored, and I
can't tap to click either. However, the two physical mouse buttons
located below the touchpad continue to work properly. Also, sudo evtest
shows that touchpad events are still delivered by the kernel.
If I apt purge xserver-xorg-input-synaptics and use the touchpad like a
generic mouse, this does not happen. If I do that and then install
xserver-xorg-input-libinput, using the touchpad via libinput, this also
does not happen.
