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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1595690 Title: Mouse freezes on login to gnome desktop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-gnome-meta/+bug/1595690/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
