Source: linux Severity: normal
Dear Maintainer, On a Lenovo L480 laptop, I've upgraded Debian from 9 (stretch) to 10 (testing). After the upgrade, the touchpad and the trackpoint was not usable anymore. This already has some bug report here, https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1803600 As a workaround, one can run the command, sudo sh -c 'echo -n "elantech"> /sys/bus/serio/devices/serio1/protocol' in order to use the touchpad. However, on a GUI Interface and without an external mouse, it's impossible to apply this workaround (switching to the terminal <CTRL>-<ALT>F1, login, and run the command above might work) I expect to be able to use the touchpad just out of the box, not needing to run the above workaround -- 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
