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.

I will state that a lot of other software is now not needed and suggest you remove it... including a lot of X stuff... so I left it alone.
Install the graphical calibrator. This helps with the setup (but didn't give me anything close to the final answer)
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

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.

Hmm, it states that a lot of other software is now not needed and suggests removing it... including a lot of X stuff... so I left it alone. Something around the package dependencies must be screwy as now the config changes to the xinput stick, but I'm not game to remove all the dependencies it suggests (one of them is xorg...)
Install the graphical calibrator. This helps a bit with the setup (but didn't give me anything close to the final answer)
==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.
