Public bug reported:
i have asus a455ld i5 5200u running kubuntu 15.04 with kernel
4.0.8-040008-generic.
touchpad is recognized as elantech version 4. everything was fine until my
notebook go to suspend and resume without touchpad working.
I tried :
modprobe -r psmouse
modprobe psmouse
it only work before suspend.
execute those commands after resume from suspend is not working.
the last thing i tried is this.
when i use this command before suspend :
insmod

these appear in the dmesg:
[ 820.207105] psmouse serio1: elantech: assuming hardware version 4 (with
firmware version 0x381f00)
[ 820.222270] psmouse serio1: elantech: Synaptics capabilities query result

the dmesg.
