HI Mo, As per Kai-Heng's request, could you please edit /etc/default/grub with the following options one at a time.
GRUB_CMDLINE_LINUX_DEFAULT="i8042.kbdreset=1 i8042.reset quiet splash" Then try GRUB_CMDLINE_LINUX_DEFAULT="i8042.kbdreset=1 quiet splash" If still nothing, please try: GRUB_CMDLINE_LINUX_DEFAULT="i8042.noloop=1 quiet splash" It's intermittent - comment 14 seems to have it working 99% of the time on my machine - has failed to work in spells of 3 hours twice since Feb. Otherwise it works reliably. Could you comment 14 as well - edit /etc/default/grub and /usr/share/X11/xorg.conf.d/50-synaptics.conf If the fix works, then we're on to something. Kai-Heng -> flat out with work for the next month or so - the i8042 commands didn't work, but I can't remember if I had the two lines in /usr/share/X11/xorg.conf.d/50-synaptics.conf commented out as well. Pretty sure I would have.
