It's almost mandatory to specify "session", but fairly rare to need to
set "desktop", so let's tweak the examples to avoid confusion and
mistakes.
```
session=gnome
securitytypes=vncauth,tlsvnc
-desktop=sandbox
geometry=2000x1200
localhost
alwaysshared
# Several common settings are shown below. Uncomment and modify to your
# liking.
+# session=gnome
# securitytypes=vncauth,tlsvnc
-# desktop=sandbox
# geometry=2000x1200
# localhost
# alwaysshared
