Public bug reported: I have had quite some issues with the touchpad on my 2013 DELL XPS 13 since installing 18.04. It worked fine on previous versions.
Typical observations: - lag - cursor movements being interrupted - more lag - single/double tap not being detected consistently - did I mention lag? Long story short: I understand 18.04 moves support for this touchpad from the synaptics driver to libinput. libinput10 1.10 apparently does not work well for this hardware, and adding the xserver-xorg-input- synaptics package did not bring back the good experience entirely. After looking into https://bugs.freedesktop.org/show_bug.cgi?id=104990 I decided to install the libinput .deb from Cosmic (current 1.11.1-1) which required libinput-bin as well. After installing both, the touchpad works as expected. Bionic is LTS, and these XPS machines have been a commercial reference for Ubuntu. I'd suggest to backport this solution to Bionic. I'm not sure HWE will bring it but even then impact for new installations could already be big. ** Affects: libinput (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1781754 Title: Ubuntu BIONIC needs libinput10 1.11.1-1 to get decent synaptics support To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libinput/+bug/1781754/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
