Debian Bullseye Touchpad Not Working SynPS/2 Synaptics Touchpad

Hello,

I am having an issue getting a touchpad working in Debian Linux. when I run

xinput list

it shows

N: Name="SynPS/2 Synaptics TouchPad"

The touchpad does not respond. It is enabled in Settings. It works fine in Windows 10 ( I dual boot ).

Any help learning how to troubleshoot this is appreciated.

From an Xorg driver perspective, show which driver is in use for that input device..,

grep -i ‘using input’ /var/log/Xorg.0.log

It could be that there is no kernel support for it (if a new device perhaps)...

dmesg | grep -i ‘input’

Using those exact commands returned nothing. Had to sudo the dmesg.

Thank you.

If this info helps I ran : sudo dmesg | grep -i Syn

Still a newbie at Linux.

Yes, sudo is sometimes required. Depends on the distro.

You can examine the Xorg log for yourself to see which input driver is used for the touchpad.

The dmesg output for the touchpad is as expected.

Which desktop environment are you using? Not disabled there perhaps?

Here is what I found in the Xorg file :

[ 4.055] (II) config/udev: Adding input device SynPS/2 Synaptics TouchPad (/dev/input/event11)
[ 4.055] (**) SynPS/2 Synaptics TouchPad: Applying InputClass "evdev touchpad catchall"
[ 4.055] (**) SynPS/2 Synaptics TouchPad: Applying InputClass "libinput touchpad catchall"
[ 4.055] (**) SynPS/2 Synaptics TouchPad: Applying InputClass "touchpad catchall"
[ 4.055] (**) SynPS/2 Synaptics TouchPad: Applying InputClass "Default clickpad buttons"


I am in Cinnamon currently but also tried Gnome. I was originally in Xfce and hopped over to test other DEs.

What model is your laptop? A lot of "older" laptops work much better with synaptics driver than libinput. By "older", basically means pre-Skylake.

It is a T14 AMD laptop. The touchpad was replaced with a 01LX660 from an X1 Extreme so everything is fairly modern.

Well, I can tell you the stock touchpad would have worked FANTASTIC, I used my T14 AMD w/ Debian 11 for a bit before moving to EndeavourOS and it worked absolutely perfectly. No idea about an X1 Extreme touchpad, but surprised it doesn't work with libinput.
