[Solved] Dell inspiron 7457 can't get touchscreen working
I checked the dell site for the model, they don't seem to offer any touchscreen driver. In fact, they barely offer any drivers for this model. I had to get the trackpad driver directly from synaptic for example.
I don't know if there's a setting in windows 10 to enable/disable the touchscreen. Device manager shows no unknown devices, but there are some generic microsoft drivers installed from what I can tell. I tried turning on tablet mode, but it didn't turn on the touchscreen. BIOS has no setting for touchscreen either.
Please throw some ideas at me. I've killed 2-3 hours on this already and it's pretty frustrating.
Solved by unseating and re-seating the monitor cable on a whim. I have no idea why this helped anything, it wasn't loose before. But as long as it's working now I'm happy.
