I get an NX Agent window, completely black.  Session started message in
the shell.

> 3. In the second run xterm -display :5

I ran "konsole -display :5" and konsole opened in the NS Agent window.

In the shell, I get
qt.qpa.xcb: X server does not support XInput 2
qt.qpa.gl: QXcbConnection: Failed to initialize GLX
qt.qpa.xcb: QXcbConnection: XCB error: 1 (BadRequest), sequence: 169, 
resource id: 225, major code: 130 (Unknown), minor code: 47

I think that these are all informational, not errors.

I get a popup (not on the NX Agent window) saying "Plasma seems to
already running on this display".
