Touchpad doesn't work

English Hardware
#1

My touchpad does not work i have tried reinstalling the driver but it didn’t help. could the community here help me?

#2

We cannot help if you don’t tell what HW you are using. Please try

sudo hwinfo --mouse

and post the result between

 tags ( the # button if you are using the web interface).
Also, make sure that the touchpad is not disabled in BIOS or by the "disable touchpad" Fn key available on some laptops (might be F9?)

Sorry about such the late answer i was trying to take a nap

Just by chance I have the same exact touchpad here, with the same hwinfo, and everything is working.
Apparently yours is OK with driver etc. Maybe it was disabled in your preferences, desktop setup, when inserting the mouse or the like?

Is yours an ASUS laptop? Occasionally I had to hit Fn+F9 to enable the touchpad when it was disabled by some desktop application. It might help to add "acpi_osi= " to the kernel boot line to have Fn+F9 working.

Check with your mouse+touchpad preferences (are you using KDE? Gnome? Other?) if it is recognized, if it it is greyed out, for instance, if you have to tick something to enable it.
Try unplugging the mouse.

And, by the way, what does exactly mean “does not work”? No effect whatsoever, or just tap not recognized or anything?

#5

I’m using KDE Plasma its a Toshiba Satellite S55-B5289 No Effect whatsoever

#6

Apparently your touchpad is recognized, connected and installed, but possibly disabled by default or user choice.
On your Satellite S55 the F5 key should enable/disable the touchpad: try it (or possibly try fn+F5).
On KDE go to
Application menu > Settings > Configure Desktop
choose Hardware > Input devices > Touchpad and go to the Enable/Disable Touchpad tab

see if something wrong is shown there, e.g. check if “Disable touchpad when mouse is plugged in” is enabled.
Check if “ImExPS/2 Generic Explorer Mouse” is in the “Ignored devices” list: according to your (and mine) HWINFO the Elantech clickpad might be recognized as such:

    Wheels: 0

but on my working system “sudo journalctl --system -b |grep Elantech” shows that the Synaptics Xorg driver takes over:

If this is not the case on your system, maybe you have to configure X accordingly: see “man synaptics”.
Hope this helps.

i did that command and the output was that


lukexj@linux-pjjw:~> sudo journalctl --system -b |grep Elantech
root's password:

fyi i wont be here i’ll be back at around 3-4pm EST so i’ll check back on this thread when im back

That means that:
a) udev is not adding /dev/input/event1 to the Xorg server and then
b) the Xorg synaptics driver is not engaging your touchpad.

The most obvious checks are:

  1. check that package xf86-input-synaptics is installed (was this the driver you tried to re-install?)
  2. again, check that the touchpad is not hardware disabled by pressing the F5 key (or possibly by checking in the BIOS, but I don’t know how to access it on Toshiba’s boxes)
  3. did you change the default Xorg config somehow (e.g. new files in /etc/X11 or /etc/X11/xorg.conf.d)?
  4. there might be problems with udev: did you install udev updates recently or modified its setup somehow?
    Installed some new HW or device that might have tampered with udev? If so, can you revert your changes?

If no option works, hope that an udev or X expert is reading this, I’m running out of ideas…

#9

Yes xf86-input-synaptics is installed and i did reinstall it still did not work, there is no disable option in bios and f5 key is not disabling/enabling it, i dont know how to edit xorg config, i did not tamper with udev in any way at least i dont think so
