Trusted X11 forwardings are not subjected to the X11 SECURITY extension controls. I've found -Y is a bit faster than -X in my experience (I've never really had many problems with X-forwarding on LANs in my experience -- even with OpenGL windows) --047d7bd75b3abc9cbc04eeba2568 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable

Holy cow, it works! Sloooooooowly, but works.
I usually u= se "ssh -Y". =A0The -Y argument toggles trusted forwarding. =A0Fr= om the ssh man-page:

=A0 =A0 =A0-Y =A0 =A0 =A0Enables trusted X11 forwarding. =A0Trusted X11 for= wardings are not subjected to the X11
=A0 =A0 =A0 =A0 =A0 =A0 =A0SECURIT= Y extension controls.

I've found -Y is a bit faster than -X in my experience (I've never = really had many problems with X-forwarding on LANs in my experience -- even= with OpenGL windows)
