I just install or try the Ubuntu 18.04 desktop amd64 on my Acer Inspire S3 . When I use the (in ms windows = file manager) to copy files, ubuntu18.04 does not recognise my laptop touchpad's Right or Left buttons.
Does not show up the [copy/paste/move/...] menu after pressing the touchpad Right button. There is no way to copy and paste files.
I have to use Ubuntu 16.04 and it works perfectly or I have to plug an external USB mouse and it also works fine.
I think the ubuntu18.04 desktop amd64 touchpad driver does not support Acer S3 Laptop.
Please give me suggestions to resolve this issue.
