Touch anywhere on your screen to check for any character output. A simple way to check for connections is to check each one for events: In the case of Itronix devices, the default is /dev/ttyS3. The actual IRQ mapping varies between manufacturers.

If there is no reference to a touchscreen device in your lsusb output, the connection is most likely through one of your serial ports. Some touchscreens might already have good or perfect calibrations, otherwise you'll need to continue to the calibration section. If your touchscreen begins to produce events, then you can permanently blacklist the usbtouchscreen driver: echo "blacklist usbtouchscreen" | sudo tee -a /etc/modprobe.d/nf

If your touchscreen has an USB interface, and it isn't working, then you may need to blacklist the usbtouchscreen driver for it to work: sudo modprobe -r usbtouchscreen If the touchscreen produces no events out of the box, check to see if it's an USB device or not: lsusbĬheck the output for any reference to a touchscreen. When encountering a new device, the first order of business is to determine how the touchscreen is connected to your computer. Skip to the section for configuring serial devices for these machines.
This method should work for most GD products, including the newer GD8000 which replaced this device. With a little trial and error however, it's relatively simple to configure this and similar devices. The device has an integrated serial touchscreen, and the manufacturer is notorious for hiding any and all documentation on legacy devices such as this one. This is a rugged laptop I picked up from ebay for a good price, which the seller wiped with Ubuntu 10.04 due to the expense of Microsoft's Windows relicensing fee. The methods documented here should work with other distros as well. Some older devices, especially those embedded in laptops such as GD Itronix line of rugged computers, use serial interfaces which lack the configuration to work in Linux. In my experience, most modern devices work out of the box with both 10.04 LTS or 12.04 LTS, but lack the proper calibration or configuration. This page is a documentation of my dealings with various touchscreen devices I've encountered.
