Since upgrading to Ubuntu 20.04.1 LTS from 18.04.5 LTS, starting Chromium Browser over a remote X session fails with
```
peter@fs-peter:~$ chromium-browser
KiTTY X11 proxy: Unsupported authorisation protocol
[28937:28937:1112/080948.455990:ERROR:browser_main_loop.cc(1426)] Unable to open X display.
peter@fs-peter:~$
```
The same happens for apps like `chrome-dominoes` (which, of course, is the critical issue ;) ).
Other applications run over remote X fine (Firefox, Jamulus, several other applications).

Apparently this is not the same as #1897224.
