I doubt it is legal for an X server to have zero screens. The DISPLAY
syntax includes the screen number at the end...
Do you check that the X11 connection was established successfully? IIRC,
xcb_connect() returns a valid pointer even when it fails:
Correct code:
xcb_connection_t *conn = xcb_connect (display, NULL);
if (xcb_connection_has_error (conn))
goto fail;
Incorrect code:
xcb_connection_t *conn = xcb_connect (display, NULL);
if (conn == NULL)
goto fail;
