Hey I've done quite a bit of googling and can't find the solution to my problem.
I've also been away from Linux for over a year so if I need to provide my information I apologize.
However I've installed Ubuntu 12.04 64bit and on my Toshiba L875D-S7332 laptop when it boots up sometimes the onboard touchpad and keyboard don't work. I'm able to use an external usb keyboard and mouse and sometimes going into Settings > Lanuage Support and switching the Keyboard input method from ibus and back fixes it. But not always. And sometimes they randomly start working.
I'm sure it's probably a simple fix but since its randomly resolving itself at times I can't pinpoint what the cause or resolution is.
