Comment 303 for bug 1220426

I have the same problem, or, at least, a similar one. My system is: HP Pavilion dm1 / Ubuntu 14.04.3 LTS / Radeon HD 6320 graphics / PS/2 Synaptics TouchPad.

My touchpad stops working periodically. A display swap (CTRL+ALT+f1 etc.) *sometimes* solves the problem, but I'm also finding that sometimes my keyboard stops working at the same time - which of course means that I can't swap displays using the keyboard. The problem does seem to be solved by connecting a USB mouse and a USB keyboard - but as it's a laptop I can't always do that.

I have tried the solution suggested at post #18. This worked very briefly, but before long the touchpad and (non-USB) keyboard stopped working again.

I have briefly looked at the solution suggested at post #251. Pardon my ignorance as a relative novice, but do I need to compile the package at https://launchpad.net/~snafu109/+archive/ubuntu/xorg-server ? I've added the PPA address as instructed, but I'm guessing that's not all I need to do?

If someone could help with this I'd be very grateful.
