Interesting. I am on BIOS Version A02. I can get the touchscreen to work if I install the "config-usb-hid- synaptics-touchscreen_1_all.db" from Dell's downloads:

I don't believe there is anyway to revert to the previous version of the BIOS either. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1273403 Title: [Dell XPS 13 9333] Touchpad not detected correctly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1273403/+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
