I too have had the same issue on my Dell Vostro V13 starting a week ago
after an upgrade - my mouse was always slow to reload after a resume
from suspend, but now it had stopped resuming altogether. After a
combination of fixes, I settled upon the following that works for me
(thanks to anxrc from Arch Linux forums for the motivation - he
originally employed the bind/unbind trick for i8042 drivers, but that
did not work for me):
Create a file /etc/pm/sleeps.d/71input-reset, and paste in it:
#!/bin/sh
#
# Reload the AT keyboard interface.
case "$1" in
hibernate|suspend)
rmmod psmouse
;;
thaw|resume)
modprobe psmouse
;;
*)
;;
esac
Make it executable:
sudo chmod +x /etc/pm/sleep.d/71input-reset
and we're done! This reloads the psmouse module every time a resume
occurs (unloads it during suspend, but that does not affect anything),
and it does work :)
