For simplification, you could use the kernel I compiled with the above patches from here:
https://www.fs.tum.de/~edelmann/synaptics-rmi Now my touchpad is recognized as full synaptics touchpad, and the touchscreen still works. An additional, minor change: When the XPS12 screen is flipped, the touchpad is now not disabled, as was the case earlier. The keyboard is disabled as before. I haven't noticed any side effects while working with this kernel in the past few weeks. It would be great if these patches work their way into Trusty. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1218973 Title: [Dell XPS 12-9Q33] Touchpad not recognized To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1218973/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
