I had similar issue on my HP laptop with elantech trackpad, where trackpad would not be responsive immediately after login. The buttons would still work, external (USB) mouse would also work.
In my case the fix was to remove synaptics driver and let libinput handle trackpad. sudo apt remove xserver-xorg-input-synaptics sudo apt install xserver-xorg-input-libinput I also created a symlink for 40-libinput.conf in /etc/X11/xorg.conf.d although it may not be needed (not present in UM 20.04). sudo mkdir -p /etc/X11/xorg.conf.d sudo ln -s /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/ A reboot was required for changes to take place properly. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/1900168 Title: touchpad motion stops responding sporadically in 20.10 mate beta To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-mate/+bug/1900168/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
