I want to use KDE (Kubuntu desktop) on my Acer ES1-711 laptop with Ubuntu but I cannot click on anything after I boot. I tried: uninstalling and reinstalling It happens when i use my touchpad(which has no buttons,just touch).Kubuntu desktop is on top of Ubuntu
The default setting for touchpads on Kubuntu does not allow tapping to be accepted as clicking. Since your touchpad does not have buttons, you'll have to use the keyboard and go to the touchpad settings and enable this function manually.
I'd suggest connecting a mouse temporarily just to enable the setting above and disconnecting it afterwards.
