<pre>I upgraded my frontend and separate backend from ubuntu 18.04 to 20.04,</pre>

<pre>The vncserver runs a fluxbox window manager.</pre>
<pre>
</pre>
<pre>After the upgrade, that no longer works even though mythfrontend works</pre>
<pre>on the backend (under the gnome desktop). It looks like a Qt-related</pre>
<pre>problem, but I am at a loss how to fix it.</pre>

<div>Can you simply `ssh -X` into the server? Ubuntu is running
Wayland, so .Xauthority is no longer used, etc.. Is the vnc
server running, or does it error out on start?</div>

<p>Mythfrontend does not run that way either. I believe the problem
is with OpenGL, does not run over a remote X session. mythfrontend
was changed to require OpenGL, where before it was optional.<br>
</p>
<p>You can use xrdp. I have used that for many years on Ubuntu and
it provides a remote login that supports OpenGL.</p>
