This was a Viewsonic all in one touchscreen computer I picked up as brand new old stock in box for NZ$60. It was not particularly quick, and RAM is low, but with a sensible distro it should be fine to run a browser display in kiosk mode (for a home automation display). At some stage I'll open it up to see if the RAM is upgradable and replace the slow 5400rpm 160GB drive with an SSD. PXE booting, or a thin/thick client setup might also be a useful method in future.

This is the config file I used. The values were mostly by trial and error and multiple iterations. You can however run xinput-calibrator (as a GUI) and that can get you closer. It allows you to touch the screen and will give you some config values back. Google wasn't too much help and xinput-calibrator also seems to return a setup that has different variable names from a working config.

Use of a Viewsonic All-in-One computer as a home automation display
**Testing some display options with Home Assistant Dashboards**

This was a Viewsonic all in one touchscreen computer I picked up as brand new old stock in box for NZ$60. It is not particularly quick, and RAM is low, but with a sensible distro it should be fine to run a browser display in kiosk mode (for a home automation display). By the preloaded software, it looks like they were for a POS terminal. At some stage I'll open it up to see if the RAM is upgradable and replace the slow 5400rpm 160GB drive with an SSD. PXE booting, or a thin/thick client setup might also be a useful method in future.
Update 22/8: I've ungraded the RAM with a donated 2GB stick and replaced the slow spinning drive with an SSD. I have a 4GB stick on the way (which may or may not work). It is perfectly useable as a touchscreen, but giving it a bit more of a speedup cheaply will be useful. I also picked up another $60 touchscreen as a spare/test unit.

==Running the xinput calibrator==
This is what running the calibrator looks like as a GUI - note the crosshair top left (it presents 4 of them one after the other for you to tap.

This is the config file I used. The values were mostly by trial and error and multiple iterations. You can however run xinput-calibrator (as a GUI, shown above) and that can get you closer. It allows you to touch the screen and will give you some config values back. Google wasn't too much help and xinput-calibrator also seems to return a setup that has different variable names from a working config.
Option "Calibration" "6575 1764 7108 1084"
