Comment 3 for bug 275825

From IRC it sounds like this is a hal caching issue:

<ion_> pitti: I was told to bug you about this. After an upgrade from a fresh hardy installation to intrepid, HAL had old information in /var/cache/hald/fdi-cache. It only stat()d most of the FDI files without opening them, and never took /usr/share/hal/fdi/policy/10osvendor/10-x11-input.fdi into account, which caused X not to find any input devices. I renamed the cache file away and everything works now.
