What would be the fcntl() or ioctl() | command in python to disable the touchscreeen? | | Seems like a useful method to add to frameworkd. I found this after googling around for a bit ~ case DEVICE_ON: + if (ioctl(pInfo->fd, EVIOCGRAB, (void *)1)) + xf86Msg(X_WARNING, "%s: Grab failed (%s)\n", pInfo->name, + strerror(errno)); ~ xf86AddEnabledDevice(pInfo); ~ device->public.on = TRUE; ~ break; ~ case DEVICE_OFF: + if (ioctl(pInfo->fd, EVIOCGRAB, (void *)0)) ioctl() itself is easily understood, given an open file descriptor it gives you a side-channel into the driver that services that file descriptor and allows you to set and query things from the context of the file descriptor, without performing any actual file operations. You can find definition of EVIOCGRAB in /usr/include/linux/input.h for use in usermode apps. I don't know python but that should be enough info for a quick meddle around, you would first open() the file descriptor normally on /dev/input/event1 or whatever. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkkgbqQACgkQOjLpvpq7dMogZQCgh623vdFwhkoDWT7+SiS4EYIW rcgAoIYo8hVFM1DiFpcyDHUMUERAKFpL =WRa1 -----END PGP SIGNATURE----- _______________________________________________ devel mailing list [email protected] https://lists.openmoko.org/mailman/listinfo/devel
