- * This code has been modified to match what is in the actual SCO X server.

- * SCO server). Mainly, it relies on streams nodes existing in /dev, not
- * creating them or unlinking them, which breaks the native X server.
- *
- * However, this is only for the X protocol. For all other protocols, we
- * do in fact create the nodes, as only X11R6 will use them, and this makes
- * it possible to have both types of clients running, otherwise we get all
- * kinds of nasty errors on startup for anything that doesnt use the X
- * protocol (like SM, when KDE starts up).
