[Solved] Touchpad stopped working

**Turns out this was a hardware issue. I had to jiggle the touchpad cable under the keyboard. Thanks for the help everyone.

My touchpad stopped working after I upgraded a few packages (I'm not 100% convinced that is the problem though), however nothing seems suspicious in the logs to me, so I'm a bit at a loss to start troubleshooting.

Xorg.0.log:

Everything worked fine before I upgraded these packages: (I'm not really sure this was the problem though; none of the packages seem that suspicious.

Any help would be appreciated. I've done a bunch of google searches, but really everything seems fine except for the fact that the touchpad is entirely unresponsive.

Re: [Solved] Touchpad stopped working

The number one thing to try would be rolling back those 7 packages to make it work again and then upgrading them one at a time. If only one package interferes with your touchpad, post Xorg log files from before and after that package is upgraded.

Great things come in tar.xz packages.
