Bug#504389: kind of a workaround

[Tim Richardson]

If I change /etc/init.d/splashy to do a sleep for a few seconds, gdm
shutdown works. 

Below shows what happens in that pause which allows the activation of vt
8 to work without manually doing Alt-F8

Change I made to /etc/init.d/splashy

-----------------------------
 stop)
	check_to_enable
	logger "splashy in shutdown mode. doing clear >/dev/tty8"
        # avoid displaying ugly text at shutdown
        clear >/dev/tty8
	logger "splashy in shutdown mode. doing clear >/dev/tty1"
        clear >/dev/tty1 
	logger "splashy in shutdown mode. doing sleep >/dev/tty8"
# I moved the sleep around to prove that it is "protecting"
splashy_chvt, not the two clear commands above
        sleep 10 
	logger "splashy in shutdown mode. doing /sbin/splasy_chvt 8"
        /sbin/splashy_chvt 8 
---------------------------


this is the relevant extract from syslog which shows what happens during
the sleep, presumably linked to the change in gdm

doing /sbin/splasy_chvt 8
---------------------------
sleep 1 instead of sleep 10 didn't work.

This is splashy_chvt

---------------------------
void
splashy_chvt (gint vt_no)
{
        gint fd = g_open ("/dev/tty0", O_RDONLY | O_WRONLY);
        if (fd < 0)
                return;
        if (!ioctl (fd, VT_ACTIVATE, vt_no))
                ioctl (fd, VT_WAITACTIVE, vt_no);
        close (fd);
}

---------------------------
it's not failing at (fd < 0), because it waits for the user to do ALT-F8
