Development was abandoned in the 1990s because hardly anyone used it, but the code still lives in X.Org. Problem is, clients marked untrusted don't work as expected and often not at all. -Y says "forward X11 SECURITY trust". In practice it marks your X11 clients as trusted which bypasses the extension so that they work correctly. -- \m/ (--) \m/ _______________________________________________ Discuss mailing list [email protected] https://lists.blu.org/mailman/listinfo/discuss
