[Bug 1885270] Re: Touchpad stopped working after upgrading to Ubuntu 20.04
Even upgrading the kernel to 5.7.8-050708-generic did not solve the problem. Also, "dyndbg=file drivers/input/* +pt" i8042.debug=1 log_buf_len=32M command solved the problem for some minutes only then the touchpad again started to be detected as ps2 generic mouse. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1885270 Title: Touchpad stopped working after upgrading to Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1885270/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1885270] [NEW] Touchpad stopped working after upgrading to Ubuntu 20.04
Public bug reported: When I upgraded to Ubuntu 20.04 my touchpad stopped working. When I used the command xinput to list the input devices there was a PS/2 Generic Mouse registered instead of my Lenovo Yoga 13 touchpad. I tried to search for the same on the askubuntu forum. I got the answer that to try and remove psmouse and then again add it using the command sudo modprobe -r psmouse; sudo modprobe psmouse This initially solved my problem but later on the same issue arose after restarting the machine. The touchpad also is again reported as a generic mouse if the system is suspended.
