I'm getting a possibly similar bug. Lately, during the first couple of minutes after login, I'm getting terrible mouse freezes every two seconds: Here is a truncated sample: juin 08 10:01:57 hostn /usr/lib/gdm3/gdm-x-session[3092]: (II) XINPUT: Adding extended input device "SEMICCHIP Usb Mouse" (type: MOUSE, id 14) juin 08 10:01:57 hostn /usr/lib/gdm3/gdm-x-session[3092]: (**) Option "AccelerationScheme" "none" juin 08 10:01:57 hostn /usr/lib/gdm3/gdm-x-session[3092]: (**) SEMICCHIP Usb Mouse: (accel) selected scheme none/0 juin 08 10:01:57 hostn /usr/lib/gdm3/gdm-x-session[3092]: (**) SEMICCHIP Usb Mouse: (accel) acceleration factor: 2.000 juin 08 10:01:57 hostn /usr/lib/gdm3/gdm-x-session[3092]: (**) SEMICCHIP Usb Mouse: (accel) acceleration threshold: 4 juin 08 10:01:57 hostn /usr/lib/gdm3/gdm-x-session[3092]: (II) event17 -

The recurrent UnloadModule: "libinput" is the symptom that cause mouse freezes. I didn't find a similar bug so far. The behavior is noticeable during boot, but it also occasionally happens later during a typical day. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1794245 Title: Attached USB devices are ignored.
