Bug#924913: trackpad on L480 unusable after upgrade to testing
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
