Touchpad not detected

Hi everyone,

I installed last version of bunsenlabs in my laptop, everything was as expected but the touchpad is not working, (mouse ok).
Here some command outputs

cat /proc/bus/input/devices | grep -I touchpad

return nothing.

# xinput list
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ Logitech USB Optical Mouse              	id=7	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ BisonCam, NB Pro: BisonCam, NB          	id=6	[slave  keyboard (3)]
    ↳ Logitech USB Keyboard                   	id=8	[slave  keyboard (3)]
    ↳ Logitech USB Keyboard Consumer Control  	id=9	[slave  keyboard (3)]
    ↳ Logitech USB Keyboard System Control    	id=10	[slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard            	id=11	[slave  keyboard (3)]

I installed xserver-xorg-input-synaptics but no working so it was removed. xserver-xorg-input-libinput, xserver-xorg-input-evdev and xserver-xorg-input-mouse are installed.

Also I have set boot options:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off i8042.reset i8042.nomux=1 i8042.nopnp i8042.noloop"

still no detected.

The touchpad was working with the previous bunsenlab version.

Thanks in advance for any advice in this matter.

Kind regards

Naddan

Re: Touchpad not detected

What relevant config do you have in /etc/X11/xorg.conf.d ?
Have you tried 'dmesg|grep i8042'?
Where did you get those kernel command options from, and what do you think they achieve? Why 'acpi=off'? Surely that is overkill.
What kernel, what hardware?
Does the touchpad not work at all, or does it work, but with the fallback driver (jittery)?

Re: Touchpad not detected

Hi ohnonot,

The only config in /etc/X11/xorg.conf.d is a file 20-intel.conf

Section "Device"
  Identifier "Intel Graphics"
  Driver "intel"
EndSection

without this, the system just display a black screen when the screen is looked and is unable to unlock it.

# dmesg | grep i8042
[    1.033510] i8042: PNP: No PS/2 controller found.
[    1.033510] i8042: Probing ports directly.
[    1.291697] serio: i8042 KBD port at 0x60,0x64 irq 1
[    1.295718] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input0

For the option i8042 from here

for the option acpi=off I do not think it is overkill since it just disable the ACPI temporary at boot time. And it is needed otherwise the system hang at boot time....

Kernel: 4.19.0-8-amd64, on a Skylake system.

The touchpad is not working at all....

Re: Touchpad not detected

My laptop is dual boot, so I installed debian9 (kernel 4.9...) as the second OS. The touchpad works as expected.

The output for xinput

# xinput list
Virtual core pointer
   Virtual core XTEST pointer ...
   SynPS/2 Synaptics Touchpad ...

Is this a matter or kernel or module/drivers?

So should I build a kernel using the kernel options from the debian9 installation?

Re: Touchpad not detected

Bringing a new distro into this thread will make things confusing.
I will continue to refer to your original question and Bunsenlabs (Helium, I presume?).

First of all you need your system to recognize the device at all.
Remove those esoteric linux command line options.
Then have a more generic look at /proc/bus/input/devices or 'lshw' or 'dmesg' or /var/log/Xorg.0.log.
If your OS does not see the device at all there isn't much we can do.

I just spent a long time doing web searches on your behalf, so please don't take this lightly.

Also "Skylake system" is a little vague, esp. since intel did not make the touchpad.

Eventually, this answer might come in handy.

I commented about my installation of debian9 as reference and as example that the touchpad is detected by debian9. I do not see how it could generate a confusion.

Obviously by calling them esoteric you do not understand them either... Without those options, the machine just hang at boot.

Well thank you but I DID that research before asking for help here.

Link provided totally useless... Thank you anyway.
