nanogui: Thread: Error 2 opening pointer calibration file /etc/pointercal.

Hi,

(On a NanoX based Helio application)

after I enter GrOpen(), I get the following:

Error 2 opening pointer calibration file /etc/pointercal.
Cannot initialise mouse
cannot open graphics


and then the application stops.

Am I missing a config file?

Rob

Visit the MotifZone (www.motifzone.org) for info on Motif!

Compile and run the program in microwin/src/contrib/GPL/tpcal, and pipe
the output to /etc/pointercal.  

tpcal draws a pretty UI for calibration, and outputs the numbers to a
file that is then read by the driver.  Some find it easier to put

"tpcal > /etc/pointercal" in the same script that you start the Nano-X
server with.  That way, the calibration gets handled when the system
starts up.

Does /etc/pointercal exist?  If not, it will need to before /bin/tpcal runs.

Actually, tpcal writes its data to stdout, so as long as /etc is
writeable, you just pipe the output to the file (tpcal doesn't have any
file ops itself, that helps make it portable).

I have run into problems where the file /etc/pointercal does not yet exist.
If I go ahead and create it and then run tpcal, all is good.  If I run it
without a pre-existing file, tpcal runs and finishes, but then nano-x has
some connection issues.  I haven't tried to debug it yet, but I thought it
was strange.
