Affects me too. Lubuntu 14.04 LTS Live CD performs well with keyboard and mouse. I use a Pentium 4 desktop PC from 2003 with 512 MB RAM.
After install of Lubuntu 14.04 LTS over an old 12.04 onto hard disk my PS/2 keyboard and USB mouse are no longer recognized. Thus cannot log in when the X login dialog appears. The hint of @Nikolai Kristiansen showed the good direction, but was not so simply realizable as in the given link. When running the Live system I cannot install any package to the hard disk. So I firstly had to try to boot from the hard disk. I had to acquire the GRUB boot menu by holding down the SHIFT key when booting. Then I booted an older kernel linux-13.0-74-generic instead of the lastly installed linux-3.16.0-4-686-pae or linux-3.16.0-4-586. On a really fresh install I would not have it. With this kernel keyboard and mouse were functional. When running the installed system with the older kernel from hard disk, `uname -r`did not help, as it returns the kernel version of the currently running system. With Synaptic I searched for linux-image, but did not find anything for the kernel version 3.16.0-4 of the distribution Lubuntu 14.04. Instead I installed the newest version of 3.16, that are linux- image-3.16.0-67-generic and linux-image-extra-3.16.0-67-generic. This updated also the boot menu to include the added kernel. When booting with this kernel version, keyboard and mouse work OK. Still I have to change the boot default. So at least now my system is working, but I am unsure, if my modifications lead to an insecure system.

I downloaded the stable amd64 iso of Ubuntu 13.04 after it was released today. It runs beautifully from a live USB key. However, after installing the OS to my hard drive and rebooting, the keyboard and mouse both fail to work. They are standard USB input devices (US layout) which have worked for years on other versions of Red Hat and Ubuntu. They work fine with the live USB version of the OS. I can't even log into the computer to collect bug data. I've tried reinstalling several times, changing the install options. Installing fresh on this computer, keeping only my old /home partition, and disallowing the installation of third-party software still produces the error. The same system has run several previous versions of Ubuntu without problems. Thanks for your help.
