I have a ultrabook and its touchpad doesn't work.

Linux mike 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt25-1 (2016-03-06) x86_64 GNU/Linux

touchpad doesn't work and it is also not listed in output of following command.

cat /proc/bus/input/devices

it's output

touchpad model : "Sentelic Finger Sensing Pad Driver" so I typed following command

modinfo psmouse

it's output

according to these information when I type following command

ls /lib/modules/3.16.0-4-amd64/kernel/drivers/input/mouse/

I see following output :

appletouch.ko  bcm5974.ko  cyapa.ko  psmouse.ko  sermouse.ko  synaptics_i2c.ko  synaptics_usb.ko  vsxxxaa.ko

so as a result I thought I should recompile psmouse module which supports sentelic touchpad. I look around the internet, I get the linux repository.

I checked the tag v3.16

I went into drivers/input/mouse and I see following files

alps.c      appletouch.c  cyapa.c        elantech.c    hgpk.c    Kconfig     logibm.c     Makefile      pc110pad.c      pxa930_trkball.c  sentelic.h   synaptics.h      touchkit_ps2.c  trackpoint.h
alps.h      atarimouse.c  cypress_ps2.c  elantech.h    hgpk.h    lifebook.c  logips2pp.c  maplemouse.c  psmouse-base.c  rpcmouse.c        sermouse.c   synaptics_i2c.c  touchkit_ps2.h  vsxxxaa.c
amimouse.c  bcm5974.c     cypress_ps2.h  gpio_mouse.c  inport.c  lifebook.h  logips2pp.h  navpoint.c    psmouse.h       sentelic.c        synaptics.c  synaptics_usb.c  trackpoint.c

which includes sentelic.h and sentelic.c files also there is a Makefile but when I hit enter the command make it says make: *** No targets. Stop.

my question is how could I compile psmouse module with the sentelic touchpad support.


I get following information from windows driver's fspad.inf file


; Localizable Strings
Provider            = "Sentelic"
DiskId1             = "Finger Sensing Pad Driver Installation Disk"
AVC.DeviceDesc      = "Finger Sensing Pad"
AVC.DriverDisplayName = "Finger Sensing Pad Driver"
AVC.DriverDisplayVersion = ""
AVC.DriverReleaseDate = "05/09/2012"
AVC.DriverCfg       = " "
fspad.SvcDesc       = "Finger Sensing Pad Driver for Windows 2000/XP/Vista/Win7"
fspadsvr.SvcDesc    = "Finger Sensing Control Service"


I tried following Live USBs and the result is same :

I checked lsmod, and proc/bus/input/devices not much different than details that I gave above. There is no touchpad thing.

Point Linux Mate Full 2.3-32 i386 Kernel  3.2.0-4
Ubuntu 12.04.4-Desktop amd64 Kernel 3.11
Xubuntu 16.04-Desktop amd64  Kernel 4.4.0

Is this a absolute kernel bug ? How could I be sure whether is this a bug or there is another solution, so according to that result I'm going to file a bug.

    1. Make and model of the Ultrabook? 2. « My touchpad is "FSP blah blah." » Really? – roaima May 23 '16 at 12:52
  • Sentelic support should already be enabled in the Debian Jessie stock kernel. Please could you post the output of grep SENTELIC /boot/config-* ? – JigglyNaga May 23 '16 at 12:54
  • @roaima the ultrabook is a product of turkey that because it is oem. there is dmidecode information on the following link gist.github.com/feyyazesat/605af917ee2a5d93206423d95959fab8 – FZE May 23 '16 at 13:10
  • @JigglyNaga that is a great command, gist.github.com/feyyazesat/37a42e147adf2a86988f3413517013d0 in my version it looks yes there is. So now my problem is changed! I don't know where to go. – FZE May 23 '16 at 13:11
  • Did lsmod report that psmouse was loaded? Do you see any error messages (including in dmesg) when you modprobe psmouse? – JigglyNaga May 23 '16 at 15:01

You can't (re)compile a kernel module by simply extracting the source and running make in its subdirectory. Each distribution has a preferred method - in your case, see section 8.10. Compiling a Kernel of the Debian handbook.

Specific drivers have to be enabled via the kernel's build configuration system. You would need to enable MOUSE_PS2_SENTELIC. However, as that is already enabled in your kernel, rebuilding isn't necessary here.

If, after modprobe psmouse, there are no helpful error messages and you still don't see anything in /proc/bus/input/devices, then it's possible that the device isn't recognised/supported by the current linux driver. You might be able to find more details on the driver development site, but that hasn't had much activity since the driver was included in the kernel.

  • thanks for your answer I will mark best answer after changing my question and getting a proper idea, recompiling idea and my approach was my total ignorance. I ask you could you please give me an idea how to properly debug my partial problem. My problem is there is no sign about my touchpad in my system. But in windows everything is properly OK. I can give you any details if you would desire. Could you please ? – FZE May 23 '16 at 13:32
  • If that is help ftp.exper.com.tr/SURUCULER/NOTEBOOK/ULTRABOOK-ULTRANOTE/L4B-01/… following windows program is my touchpad driver – FZE May 23 '16 at 13:34
  • I updated my question and added several information from windows driver. – FZE May 23 '16 at 13:42
