Dear Romainm I upgraded the kernel and rebooted: schloegl@debian10:~$ uname -a Linux debian10 4.19.0-4-amd64 #1 SMP Debian 4.19.28-2 (2019-03-15) x86_64 GNU/Linux With this kernel the trackpoint is working, the trackpad is still not usable. (This improves the situation because now at least one pointer device is available). > - According to the bug on launchpad and to the fix pushed upstream, the > fix seems to be an hardware quirks, could you give me the output of the > following command : > $ /sys/bus/serio/devices/serio1/firmware_id root@debian10:~# cat /sys/bus/serio/devices/serio1/firmware_id PNP: LEN2036 PNP0f13 > > Thanks, > Regards, > Romain Thank You, Alois >> -- System Information: >> Debian Release: buster/sid >> APT prefers testing >> APT policy: (990, 'testing'), (500, 'stable') >> Architecture: amd64 (x86_64) >> >> Kernel: Linux 4.19.0-2-amd64 (SMP w/8 CPU cores) >> Kernel taint flags: TAINT_WARN, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE >> Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), >> LANGUAGE=en_US:en (charmap=UTF-8) >> Shell: /bin/sh linked to /bin/dash >> Init: systemd (via /run/systemd/system) >> LSM: AppArmor: enabled
