Public bug reported:
I have ubuntu 16.04 dual boot with windows 10. In ubuntu external mouse
works but Touchpad is not working, it is working in windows. I checked
with this command "cat /proc/bus/input/devices" but there is not
Touchpad device in log(log file attached).
I also tried to upgrade using
sudo apt-get update
sudo apt-get dist-upgrade
but it didn't help.

There was some issue during ubuntu installatin, so I replaced some
contents in grub to make it work again. I replace this ("quiet splash"
-> "noapic noacpi nosplash irqpoll"). maybe this could be problem, so I
mentioned. My current grub content is following.
recordfail
load_video
gfxmode $linux_gfx_mode
insmod gzio
if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi
insmod part_gpt
insmod ext2
set root='hd0,gpt6'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt6
--hint-efi=hd0,gpt6 --hint-baremetal=ahci0,gpt6

else
search --no-floppy --fs-uuid --set=root bc1b7ed6-1148-4cfe-98b0-f5bb0ee883bb
