Hello, since migrating to Linux 5.12, the Elan touchpad stopped working for me. I created a bug report on https://bugzilla.kernel.org/show_bug.cgi?id=213093 2but I am not sure whether that reached anyone here. The symptom is that when running 5.12, the touchpad does not show up. I tested so far with 5.12.3, 5.12.4 and 5.12.6, all behave the same, latest dmesg output on 5.12.6 does not show the touchpad driver loading, only the one for the trackpoint: [13:35] nb3:~% dmesg| grep -i elan [ 11.845386] psmouse serio1: trackpoint: Elan TrackPoint firmware: 0x62, buttons: 3/3 [ 11.857853] input: TPPS/2 Elan TrackPoint as /devices/platform/i8042/serio1/input/input23 [13:35] nb3:~% The hardware I am using is an Lenovo X1 nano, however other people also reported this problem before. If there is anything I can do to debug this, any pointer would be appreciated. Best regards, Nico -- Sustainable and modern Infrastructures by ungleich.ch
