Ubuntu – mouse and touchpad settings missing

It is possible to get back the touchpad and mouse settings in your control panel.

You can simply install it either from synaptic package manager or by using the following apt command

sudo apt-get install touchpad-indicator

If you are facing the problem with the settings just remove the mouse and touchpad settings file by the following command

rm -fr ~/.gconf/desktop/gnome/peripherals/mouse

Hope this will help you better to resolve your issues.

Ubuntu – ALPS touchpad detected as PS/2, corrected with psmouse-dkms-alpsv7 but reset after reboot

You only need to install the DKMS package once, it will be copied to /var/lib/dkms/. So, /tmp/ was fine, and you really should not create /msp/ either as it violates the Filesystem Hierarchy guidelines.

My guess is that psmouse is considered a crucial module which should be available when Ubuntu boots, and therefore ends up in the initial ramdisk. As your new module replaced an existing module (psmouse), you can try to run the sudo update-initramfs -u to get your new module in the initrd. You only need to do this once as further kernel updates will trigger this automatically.
