Using 6.3.0 (no service packs), and initializing on a serial connected elo touchscreen. The system is intended to be embedded. Starting from a script. In this case an interactive test script, but a script.
The hardware is a standard intel SBC with an i830 , all the usual stuff, but no mouse.
The touchscreen is visible on /dev/ser5
When starting, using the recipe in the manual, the serial driver, Photon, the elo and io-graphics all start without any complaints. The io-graphics command looks like this:
io-graphics -di830 vid=8086,did=3582,index=0,photon,xres=800,yres=600,bitpp=15,refresh=60 -pphoton touchscreen &
This is followed by pwm &
In the script I add two pterms after the pwm is started.
When this script is run I get the photon graphics OK with a perfectly usable pterm on top left of the screen, slightly overlapping a pterm I can’t get to (don’t care except that I can’t change focus). In the pterm I can run “calib” and the touchscreen responds quite precisely.
It just doesn’t affect th pointing device for Photon.
Finally I get bored and slay Photon.
The error messages become visible, and there’s the title page. Error: found graphics region with no capabilities manager.
I isolated this to pwm as the complainer, but I have to suspect something else as the culprit. Something is missing, some file or option that connects that touchscreen output and/or capabilities to the Photon that is running on the machine.
Anyone have any clues?
