I have found the cause so far that the touchpad MSFT0001: 00 04F3: 3140 is recognized, but no suitable driver is found.
With the touchpad ELAN0001: 00 04F3: 3140 it seems to work with a few tricks. ELAN is also available in the kernel config, but MSFT is not. I just don't understand why there are two different names (ELAN and MFST) under the same hardware ID - what did Lenovo do? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1887190 Title: MSFT Touchpad not working on Lenovo Legion-5 15ARH05 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1887190/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
