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.
