A quick update: I upgraded from 13.10 to 14.04 a couple of days ago. This appears to have fixed the problem. Running xinput now shows the touchpad recognised correctly as:
"AlpsPS/2 ALPS GlidePoint" The touchpad settings are back in System Settings > Mouse & Touchpad and I can now (finally!!!) disable "Tap to click". Hurrah! Vertical multiple line scrolling works using the physical middle 4-way button below the touchpad and horizontal scrolling works again too, using the same 4-way button. My only frustration is the many, many months it has taken to get to this point but nevertheless I'm happy to say this issue is now resolved, so "thank you" to whoever was responsible. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1254092 Title: Touchpad not recognised on Acer Aspire 5720 after upgrade to 13.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/1254092/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
