Comment 5 for bug 1595690

I upgraded from 14.04 to 16.04 today.
Mouse is working fine at the point logins are displayed.

Using Unity login, the mouse works for a few seconds after entering password, then freezes before launcher appears and ceases to work until reboot.

After reading replies in the askubuntu question above, I have installed gnome-session-flashback and rebooted. Now I have three desktop choices for login.

Ubuntu: freezes as before
Gnome Flashback Compiz: freezes in the same manner.
Gnome Flashback Metacity: is working.

My Video hardware shows as NVIDIA Corporation C61 [GeForce 7025 / nforce 630a] in Software & Installed driver is xserver-xorg-video-nouveau.
