A couple of days ago, I installed Ubuntu 14.04 on a Dell I7352-3111SLV 13 inch touchscreen laptop. Initially, the touchpad worked fine. The first time I suspended, the touchpad stopped working, even with a reboot. I've since reinstalled Ubuntu a couple of times to try to solve the problem without success. The latest time, the touchpad didn't work even with a fresh install.

I have tried several fixes without success including:

How to install Synaptics on touchpad on Ubuntu 14.04

Synaptic touchpad on laptop not working

Since the computer is also not resuming even half the time from Suspend, I enabled hibernate. The odd thing is that coming off a hibernate/resume, the touchpad functions again properly each time. However, when I reboot, the touchpad is non-functioning again until I hibernate.

Even when the touchpad does not work, it is still detected.

I'm fairly new to Linux and I would appreciate any suggestions. Maybe there are log files that could be used to compare what is happening with the touchpad on a reboot as opposed to resuming from hibernate?

  • Check Touchpad whether it is in enabled mode or not ? @user3221829 – Sridhar Aug 16 '15 at 11:38
  • I checked with dconf editor. The touchpad is listed as enabled both when it is working and when it is not working. <img src="techpoweredmath.com/wp-content/uploads/2015/08/…"> – lgallen Aug 17 '15 at 1:07
  • Sorry. Having some problems with the markdown for images, but this is a link to the screenshot: techpoweredmath.com/wp-content/uploads/2015/08/… – lgallen Aug 17 '15 at 1:20
  • Further information that may be helpful. /var/log/dmesg shows the following messages: [ 1.641647] psmouse serio1: synaptics: device claims to have extended capability 0x0c, but I'm not able to read it. [ 1.768585] psmouse serio1: synaptics: Unable to initialize device. [ 2.980093] psmouse serio1: Failed to enable mouse on isa0060/serio1 – lgallen Aug 17 '15 at 2:22
  • Your Configuration is very similar of Dell Inspiron 13 7000 as per specification and Your System Supports only Windows 8.1\10-64 bit & BIOS as per DELL Official site. So better try this askubuntu.com/questions/527793/… It may help you – Sridhar Aug 17 '15 at 3:23
