I run Debian 10/Gnome on a Lenovo Y2P, so far without problem. In particular
uname -a yields:
Linux deepthought 4.19.0-13-amd64 #1 SMP Debian 4.19.160-2 (2020-11-28) x86_64 GNU/Linux
Since I once ran
sudo halt on 4.19.0-11-amd64,
synclient -l yields:
Couldn't find synaptics properties. No synaptics driver loaded?
I.e. the touchpad works, but less sensitive, no 2-FingerScroll, no click-drag, and the Mouse & Touchpad settings menu is reduced to a basic form. On the previous version, 4.19.0-10-amd64 the touchpad still works completely normal.
Here is, what I tried so far:
xserver-xorg-input-synapticsinstalled (and re-installed, to no avail).
As in this StackExchange answer,
↳ PS/2 Synaptics TouchPad id=13 [slave pointer (2)]
but copying the synaptics config file, as suggested:
cp /usr/share/X11/xorg.conf.d/70-synaptics.conf /etc/X11/xorg.conf.d/70-synaptics.conf
and rebooting did not solve the problem. The content of
# Example xorg.conf.d snippet that assigns the touchpad driver # to all touchpads. See xorg.conf.d(5) for more information on # InputClass. # DO NOT EDIT THIS FILE, your distribution will likely overwrite # it when updating.

Re-adding the module to the kernel did not help but tells me this:
insmod /lib/modules/4.19.0-13-amd64/kernel/drivers/input/mouse/psmouse.ko proto=imps
Following this reddit, i checked
$ sudo dmesg | grep -i PS/2 [ 1.799257] i8042: PNP: PS/2 Controller [PNP0303:PS2K,PNP0f13:PS2M] at 0x60,0x64 irq 1,12 [ 1.812958] mousedev: PS/2 mouse device common for all mice [ 2.218457] input: PS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input5 [ 246.027504] input: PS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input81
However, my xorg log contains nothing about Synaptics:

The error in here stems from another halted project - it has not influenced the synaptics driver in the past. But I don't see anything about the latter.
(side question: i removed the file
20-displaylink.conf a while ago, i.e. this file doesn't exist anymore. when/how does this log get updated?)
As I expected, adding the module automatically at start up, as suggested here did not change anything.
This link tells me, that Gnome 3.20 no longer supports synaptic drivers, but switched to libinput. I have 3.30.2., so while the behavior would make sense, I have the same Gnome version on the Kernel version 4.19.0-10-amd64, and it works just fine. Anyhow, this wiki entry should then tell me how to switch to libinput - but i seem to be too stupehd for that, i.e. I don't get what I need to do.
Now, slowly desperation kicks in, as I am not (yet) familiar enough with Linux, to cook up my own solution. Hence, any help is greatly appreciated.
Also: how could
halt mess this up? Is there some danger to it, I should know about?
Thank you big time!
