After upgrading 13.04 to 13.10 I have no keyboard. Fresh install of 13.04 and the keyboard is back, Fresh install of 13.10 and no keyboard. The laptop is an older LW40 1.8 Ghz 2Gb ram. A usb keyboard works fine but defeats having the laptops portability. Oddly Fedora 19 has the same impact on the keyboard. Any suggestions appreciated.
