I turned my touchpad off on my laptop from the system settings. This was because I had a mouse plugged into my USB Hub and the touchpad bugged my occasionally. I almost immediately realized that I'd need to turn it back on before going mobile with my laptop where I wouldn't have a mouse.
When I tried to turn it back on, I noticed that there were no touchpad settings in the system settings mouse area anymore, gone, not there.
I tried xinput list, but the touchpad wasn't in the list. I tried the synclient command with no luck.
The mouse still works fine, but I can't turn the touchpad back on.
Any ideas?
