Elo Touchscreen losing calibration when powered off
hoogenboom:
Hello,
I am using TCL 3.8.4 and Xorg-7.5 with an Elo Touchscreen (1515L). I followed this handy guide (http://forum.tinycorelinux.net/index.php/topic,8753.0.html) and its working well. However, when I power off the monitor and back on again the calibration resets. The only thing that brings it back is a reboot or exit to prompt and running startx. I'm wondering if there is a process that I need to be looking at. Thanks

Check your Elo manual and see if there is a save calibration procedure.

No save calibration feature that I can find in the manual. Also same monitor running on TCL 7 and Xorg-7.7 on very similar hardware is working great.
curaga:
If newer Xorg works better, then I think you should upgrade. Of course if there's lots of those machines in production, etc, you could try to isolate if it was the elo driver or some other part, then backport.

In the days that I dealt with elo touchscreens there was a file /etc/opt/elo-usb/USBConfigData that I had to save in /opt/.filetool.sh to preserve the screen calibration. I don't know if they've fixed their ugly paths, but is there something similar now?
