Touchpad not fully working

[francesco]

Hello everyone,

i’ve just deleted ubuntu mate 16.04 and installed 18.04.1 on my acer aspire 5920g .

It features a touch panel on top (working well), 2 buttons and between them a scroller-joystick. With 16.04 the scroller was working, so if i pushed it to left right up or down it was handy.

With 18.04 doesn’t seem to work. Any ideas?

Thank you in advance!

A reason why it might be different is that Ubuntu MATE 18.04 uses the libinput touchpad driver by default instead of the older synaptics driver. Libinput is actively being developed and works better for a lot of newer devices, but I’ve noticed some devices still seem to work better with synaptics. Eventually synaptics will be retired, but for now you can install it

sudo apt install xserver-xorg-input-synaptics

and reboot to use it.

Cool it works .

Let’s hope that package will be usable also for MATE 20.04, this pc despite the age is working really well for my purposes after i’ve changed the hdd with an ssd (and soon i’ll upgrade to 4gb ram).

Or let’s hope that libinput will add support for this touch too.
