Touchpad not recognized, not listed

My device's touchpad (current generation Thinkpad) is not functioning: touching it or pressing the buttons does not lead to any events listed in xev. It is sometimes detected, but I cannot establish when it is and when it isn't: this morning, it was not detected. Booting a few hours later, it was detected. Now I rebooted four times, and it was not detected a single time.

Also, the device is not listed in xinput:

% xinput list
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ Logitech USB-PS/2 Optical Mouse         	id=10	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Power Button                            	id=6	[slave  keyboard (3)]
    ↳ Video Bus                               	id=7	[slave  keyboard (3)]
    ↳ Video Bus                               	id=8	[slave  keyboard (3)]
    ↳ Sleep Button                            	id=9	[slave  keyboard (3)]
    ↳ Integrated Camera                       	id=11	[slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard            	id=12	[slave  keyboard (3)]
    ↳ ThinkPad Extra Buttons                  	id=13	[slave  keyboard (3)]

The Logitech devices is my external USB mouse.

Also, nothing in /proc/bus/input/devices

Re: Touchpad not recognized, not listed

What model ThinkPad? Have you tried messing with the synaptics configuration, as suggested here: https://wiki.archlinux.org/index.php/Le … 0#Touchpad  This is for the X230 but I had to do some tinkering with the X240 as well.
Though this wouldn't explain why the trackpad isn't showing up...

No, I didn't. I have libinput installed. However, that particular synaptics configuration wouldn't do anything for me, since there is no product to match if it doesn't turn up in the xinput list... I know that if it turns up, it is called:

PS/2 Synaptics TouchPad

(So the same as in the article, just not SynPS/2). But it doesn't show up....

Model is a W550s.

No results, the driver is not loaded. Why would you expect it to work?

Re: Touchpad not recognized, not listed

I have a HP 255 G2 and experience a similar problem. If I boot the laptop normally, there is no evidence of a touchpad in /proc, nor dmesg, nor lsmod etc. If I shutdown, remove the battery and power cable for a few seconds, then put it back together and boot, the touchpad is detected and works fine.

Good to know I am not the only one with that issue. Do you maybe have a Windows partition installed? I would be curious to see what happens if you boot to Windows immediately after you notice the touchpad not to be working.

Also, I have open a bug report here: https://bugs.archlinux.org/task/44162

Maybe you could attach your info there as well.

Sorry I don't have Windows. This isn't sporadic for me; it always happens the way I described. Once I do the battery trick I can reboot and the touchpad works, but if I poweroff then boot it is not detected. Here is dmesg output of the touchpad for what it's worth:

Could I still ask you to add that info to the bug report I opened? Just so that they have some confirmation that other users are affected by a similar issue.

Re: Touchpad not recognized, not listed

Has your firmware the ability to disable 'Fast boot'?

Re: Touchpad not recognized, not listed

It does. I just disabled it to see if there is an effect: no Touchpad on this boot. I suppose this means fastboot had no effect.
