Since you said the trackpad works in Wayland until you run Software Center, please:
1. Log into 'Ubuntu on Wayland'. 2. Make sure the trackpad works. 3. Open a Terminal and run: dmesg -w Leave it running but tap Enter several times to make some blank lines. 4. Open Software Centre. 5. Does the Terminal window now show any new messages? ** Summary changed: - Synaptic Trackpad does not work in Xorg sessions + [Dell Venue 11 Pro 7140] Trackpad does not work in Xorg sessions ** Package changed: xorg-server (Ubuntu) => linux (Ubuntu) ** Summary changed: - [Dell Venue 11 Pro 7140] Trackpad does not work in Xorg sessions + [Dell Venue 11 Pro 7140] Trackpad does not work -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libinput in Ubuntu. https://bugs.launchpad.net/bugs/1877655 Title: [Dell Venue 11 Pro 7140] Trackpad does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libinput/+bug/1877655/+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
