Comment 3 for bug 74286

Yes, when a live CD boots, it creates a temporary / file system in the memory of your computer that contains most of the files you would expect in a typical install.

Sorry to make you do this by hand, but while you are at it, could you also:
1. Alt-F1 to open the panel menu, navigate to the `Accessories` section, and select `Terminal`
2. Give us the output of `grep -i "mouse" /var/log/Xorg.0.log` (case-sensitive, no `quotes`)

Thanks
