problems calibrating touch screen (elotouch): ts_calibrate and ts_open are broken

[ahoros]

I have recently connected my Dell D420 laptop to Elotouch Intellitouch touchscreen monitor
the x server did seem to detect it (via USB connection) however the coordinates are reversed (up with down, left with right)

I wanted to start up calibration utility ts_calibrate found in Cannonical package : libts-bin

however the package seems to be badly broken:

root@Delik2:/etc# ts_calibrate
ts_open: No such file or directory
root@Delik2:/etc# ts_open
ts_open: command not found
root@Delik2:/etc# ts_test
/dev/touchscreen/ucb1x00: No such file or directory
root@Delik2:/etc# ts_calibrate
ts_open: No such file or directory
root@Delik2:/etc#

none of the key utilities seem to be working

By the way does anybody know how can I fix my calibration problem?

Sorry, something just went wrong in Launchpad.

We’ve recorded what happened, and we’ll fix it as soon as possible. Apologies for the inconvenience.

Trying again in a couple of minutes might work.

there are at least three packages starting with letters: 'libts"
but ts_calibrate seems to be assigned to libts-bin

is there anybody tracking this?

Nobody is tracking this in Ubuntu - I came across it by chance. Report bugs in Debian to get a response.

The answer here is in the manpage for ts_calibrate - you need to set the TSLB_TSDEVICE environment variable to be able to use any of the ts_* commands and it sounds like your touchscreen is not appearing in the expected place. You need to work out which device is used and set that environment variable.
