Wladimir Mutel, to advise, theorizing what might be fixed isn't nearly as helpful as testing the latest Ubuntu kernel for your release, and if still reproducible the latest mainline kernel (now 4.9).

Also I see in dmesg that ETPS/2 Elantech touchpad is initially created as /devices/platform/i8042/serio1/input/input5, and after module reload, it is recreated as .../input292 (but only after first module re-probe, next times nothing happens at all). The script in /etc/pm/sleep.d apparently does not do anything (probably need to re-test it after a fresh boot) i8042/serio/psmouse/elantech lines: i8042: PNP: PS/2 Controller [PNP030b:PS2K,PNP0f03:PS2M] at 0x60,0x64 irq 1,12 serio: i8042 KBD port at 0x60,0x64 irq 1 serio: i8042 AUX port at 0x60,0x64 irq 12 input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input3 psmouse serio1: elantech: assuming hardware version 4 (with firmware version 0x381f00) psmouse serio1: elantech: Synaptics capabilities query result 0x10, 0x14, 0x0e. psmouse serio1: elantech: Elan sample query result 00, 23, 64 input: ETPS/2 Elantech Touchpad as /devices/platform/i8042/serio1/input/input5 after manual mod-reprobe without pm-suspend : psmouse serio1: elantech: assuming hardware version 4 (with firmware version 0x381f00) psmouse serio1: elantech: Synaptics capabilities query result 0x10, 0x14, 0x0e. psmouse serio1: elantech: Elan sample query result 00, 23, 64 input: ETPS/2 Elantech Touchpad as /devices/platform/i8042/serio1/input/input292 (then touchpad dies off) $ ls -l /etc/pm/sleep.d/05_elantech -rwxr-xr-x 1 root root 128 лис 22 20:33 /etc/pm/sleep.d/05_elantech $ cat /etc/pm/sleep.d/05_elantech #!/bin/sh case "$1" in suspend|hibernate) modprobe -r psmouse ;; resume|thaw) modprobe psmouse ;; esac after initial boot and pm-suspend : touchpad dies off, no records about its re-detection appear in dmesg now preparing to try a patch posted to linux-input mail list referred to at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1490130/comments/8 ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.2.0-19-generic 4.2.0-19.23 ProcVersionSignature: Ubuntu 4.2.0-19.23-generic 4.2.6 Uname: Linux 4.2.0-19-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.19.2-0ubuntu6 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: mwg 1482 F.... pulseaudio /dev/snd/controlC0: mwg 1482 F.... pulseaudio CurrentDesktop: KDE Date: Mon Nov 23 18:50:47 2015 HibernationDevice: RESUME=UUID=6932e499-f0ad-4456-b93c-2b7f9bf763dc InstallationDate: Installed on 2009-11-01 (2213 days ago) InstallationMedia: Kubuntu 9.10 "Karmic Koala" - Release amd64 (20091027) MachineType: ASUSTeK COMPUTER INC.
