Subject: [PATCH] gdm/util: Set minimum display time for authentication
 messages
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Short messages like "PIN locked" were previously displayed for only
480ms (10 chars × 48ms), making them impossible to read. Ensure all
messages are shown for at least 2 seconds.
