I found a workaround which should make the touchpad work in ps/2 mouse emulation mode. https://bugzilla.redhat.com/show_bug.cgi?id=1110011 You need to add a Kernel Boot Parameter to set the flag i8042.nomux=1 psmouse.proto=bare which will enable PS/2 Mouse Emulation mode on your touchpad. Edit your default grub file. sudo nano /etc/default/grub Find the line that mentions GRUB_CMDLINE_LINUX and add the flag: GRUB_CMDLINE_LINUX="i8042.noloop=1 psmouse.proto=bare" Then save the file and run a grub update. sudo grub-update Then restart the system . product: X750LN Linux version 3.13.0-36-generic Distributor ID: Ubuntu Description: Ubuntu 14.04.1 LTS Release: 14.04 Codename: trusty ** Bug watch added: Red Hat Bugzilla #1110011 https://bugzilla.redhat.com/show_bug.cgi?id=1110011 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1371914 Title: [Asus X750LN] Touchpad not recognized To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1371914/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
