To whom it may concern. Hope I am communicating through the right channel. Since about a two months ago my touchpad stop working. At first I thought it was a hardware problem. I bought a new one and realized that it was not the case. Tried to roll back to a previous kernel and I had no results. After a some weeks of looking trough internet I realized that the touchpad was detect by libinput (or xinput) after suspend my computer. But still can not record or debug-evente via libinput, it just doesn´t show any event. I am currently using debian 12 with kernel 6.1.0-21-amd64. ## Steps to reproduce `libinput list-devices` does not show my touchpad. After suspend it shows the device. If I shutdown my computer the devices is not detected again. ## Required information - hardware information: - Thinkpad T440p - The current touchpad had separate physical hardware buttons. The previous one hasn't, but still was not working. - libinput (version 1.22.1): Device: SynPS/2 Synaptics TouchPad Kernel: /dev/input/event16 Group: 8 Seat: seat0, default Size: 98x54mm Capabilities: pointer gesture Tap-to-click: disabled Tap-and-drag: enabled Tap drag lock: disabled Left-handed: disabled Nat.scrolling: disabled Middle emulation: disabled Calibration: n/a Scroll methods: *two-finger edge Click methods: *button-areas clickfinger Disable-w-typing: enabled Disable-w-trackpointing: enabled Accel profiles: flat *adaptive Rotation: n/a After report it in a issue (https://gitlab.freedesktop.org/libinput/libinput/-/issues/1011) to the libinput gitlab. Peter Hutterer kindly point me in the right direction. The command 'dmesg -H | grep -i TouchPad' shows: [ +0.000012] psmouse serio1: synaptics: Your touchpad () says it can support a different bus. If i2c-hid and hid-rmi are not used, you might want to try setting psmouse.synaptics_intertouch to 1 and report this to linux-input@xxxxxxxxxxxxxxx.
