I just checked. It turns out that brltty actually does need to open the vt right away. For example, it uses GIO_UNIMAP to retrieve the Unicode map so that it can back translate font positions into characters in order to determine what's on the screen. It also uses VT_GETHIFONTMAKS in order to know how to interpret the attributes bytes. Yet another thing it does is use VT_GETSTATE in order to determine which vt is active (vt_stat.v_active). Even open on demand, therefore, would result in the tty being opened almost immediately. -- Dave Mielke | 2213 Fox Crescent | The Bible is the very Word of God.
