    The relevant line to me is the "Client did not advertise support for
    the Graphics Pipeline, closing connection". I did a quick web search
    for this and saw multiple reports of this with Guacamole. Is there
    any fix for this? This is a brand new, vanilla Ubuntu 24.04
    workstation with nothing custom, so I would think one of the more
    common workstation types people would want to connect to.


That's interesting that the connection actually requires this - I've not seen that before. Usually it's just an enhancement for performance. I wonder if there's a way to adjust the Ubuntu side so that it doesn't require it?


I suspect this may have been a conscious implementation choice on the part of this particular RDP server to reduce scope and avoid the complexity of all those traditional raster operations.
