Comment 5 for bug 875154

Craig: I'm not seeing the data I expect. Did you reboot or run 'sudo modprobe -r psmouse; sudo modprobe psmouse' after installation? This is necessary to use the new driver. If you did one of those, can you run the following in a terminal to make sure that the following file exists?

  ls /lib/modules/$(uname -r)/updates/dkms/psmouse.ko

Also, something to note is that if you have the debug driver package installed when testing the mainline build it's going to use that driver in preference to the one in the mainline build. That's not what we want, so please uninstall the package prior to testing the mainline build.
