Have a really strange issue with my keyboard and trackpad after installing ubuntu 12.04. It picked up both fine with the livecd and in the install, but for quite awhile now, I find when I power my laptop up (Toshiba Satellite L775D-S7132), when I hit the login screen much of the time I won't have any keyboard or touchpad.

I can plug in a usb mouse and then at least restart or shut the laptop down and then keep trying until it picks it up correctly, but it's really a pain to have to do that all the time.

Are there quite a few bugs related to keyboard and trackpad issues with the new version?

I really want to get this issue resolved as it's a major nuisance.

Otherwise, my hardware gets picked up fine. Video, audio, wlan, usb work perfectly and I don't ever have any issues with them.

What's the best way to figure out the problem?

Thanks in advance,

C.
