The post #9 shows this change to xf86-input-evdev allows generic-usb
kernel driver to work:
} else if (TestBit(ABS_PRESSURE, pEvdev->abs_bitmask) ||
TestBit(BTN_TOUCH, pEvdev->key_bitmask)) {
//if (has_lmr || TestBit(BTN_TOOL_FINGER,
pEvdev->key_bitmask)) {
// xf86Msg(X_PROBED, "%s: Found absolute
touchpad.\n", pInfo->name);
// pEvdev->flags |= EVDEV_TOUCHPAD;
// memset(pEvdev->old_vals, -1, sizeof(int) *
pEvdev->num_vals);
//} else {
xf86Msg(X_PROBED, "%s: Found absolute
touchscreen\n", pInfo->name);
pEvdev->flags |= EVDEV_TOUCHSCREEN;
pEvdev->flags |= EVDEV_BUTTON_EVENTS;
//}
}
I believe that shows this device is declaring a touchpad-like left,
middle, or right button... which a touchscreen should not. That helps
validate that its probably the simple multi-input issue that past
eGalax's have had and that it should work with standard open source
kernel drivers once thats addressed.
Hopefully, we can defeat that evil desire for the easy/quick fix of
using the eGalax binary proprietary drivers under Linux.
