I restarted my computer and now the touchpad doesn't show up at all and doesn't work. I followed the instructions here https://wiki.ubuntu.com/DebuggingTouchpadDetection#In_case_your_Touchpad_doesn.27t_work_at_all_.28No_response_from_the_Touchpad.29 and the instructions say to file a bug since I don't see a synaptics touchpad entry in /proc/bus/input/devices. As instructed, I will also attach that file.
