Builtin touchpad is not seen in 'DELL Latitude E5550' after the reboot during update.

[Anna Nikiforovskaya]

After an unexpected reboot, cursor disappeared. The only thing, which helped -- typing

gsettings set org.gnome.settings-daemon.plugins.cursor active false

and rebooting again. However, cursor now doesn't move with a touchpad. I have found this https://wiki.ubuntu.com/DebuggingTouchpadDetection. I have checked, if cursor moves with a mouse and it does. And there's no touchpad in /proc/bus/input/devices. So, I was recommended there to put it here as a bug.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.16 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.
