The workaround (reloading psmouse) apparently solves the problem that the touchpad (/dev/input/eventX) is grabbed by the wrong XServer:
This can be observed by running: sudo lsof /dev/input/eventX First XServer: Touchpad works. (as the devide is grabbed by the process of the first XServer. Switching to second XServer Second XServer: Touchpad does not work. The device is still grabbed by the first Server sudo rmmod psmouse sudo modprobe psmouse Second XServer: Touchpad works. The device is now grabbed by the second Server. Can anybody explain how the normal procedure of grabbing/releasing of devices works? If i repeat the above test with an USB mouse, this procedure works... -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gdm in Ubuntu. https://bugs.launchpad.net/bugs/1247388 Title: Mouse cursor disapear / mouse stops working, when switching user Status in “gdm” package in Ubuntu: Confirmed Bug description: I have upgraded to Ubuntu 13.10 Gnome3 amd64, from Ubuntu 13.04 x86 where I used both Unity, KDE and Gnome, and in the old setup it worked fine. Now when I select switch user , I come out to the login screen and the mouse cursor is gone. Switching back to the first user the mouse is back. If the second user with no cursor runs: sudo modprobe -r psmouse sudo modprobe pmouse the mouse works again, but then it stops working for the first user. It could alse be that the cursor is still ther but it doesn't move. I run a Dell laptop with a Synaptics touchpad. What can I do to provide more information?
