Yes, assuming you mean libpyqt5_py2.so. I am using the version from the 5.9 directory, and qt designer is version 5.9.5.
Just as a test, I tried using the 5.7 version of libpyqt5_py2.so. No difference. No errors, it still showed up in about plugins.
The qtvcp install instructions mention the possibility of compiling it myself, and I'm open to trying that if it seems like it would help. It's not clear to me exactly what I'd be trying to compile though or where I get the source files from.
From the instructions:
Then you need the python-module loading library added.
Qtvcp uses QT5 with python2 - this combination is not normally available from
repositories. You can compile it your self or there are precompiled versions
available for common systems.
in lib/python/qtvcp/designer there are folders...

here is one more thing to try:
export PYQTDESIGNERPATH='/path/to/plugin/directory/'
Otherwise here are two instructions for compiling.
Obviously you must adjust for the qt5.9 version.

Success!!
I had to compile PyQt5 from source. Setting PYQTDESIGNERPATH before compiling had no effect.
I followed the instructions from your first link, but swapped in newer versions of SIP and PyQt5, since my Qt version is 5.9.5 (not 5.7.x) Here's the full list of commands I ran:
After all that, it still didn't work, but I think that was because I still had PYQTDESIGNERPATH set, and it must have been set to the wrong directory (I had previously been trying all the paths I could think to try). Setting:got it working.
Note that when things weren't working, it was confusing to me exactly which path PYQTDESIGNERPATH should be set to. My best guesses were '/usr/lib/x86_64-linux-gnu/qt5/plugins/' and '/usr/lib/x86_64-linux-gnu/qt5/plugins/designer/'. I can now see that setting either of those paths will prevent the linuxcnc widgets from loading. If it is set at all, it really needs to point to the python directory.
Note also that I had tried setting PYQTDESIGNERPATH to the correct python directory before compiling PyQt5 and it did not help, so compiling from source really was necessary.
Finally I unset PYQTDESIGNERPATH, and it still works, so setting it does not appear to be necessary in my case.
Thanks so much for your help Chris! Now I'll be on to trying to modify QtDragon to fit my 1280x1024 screen.

You could also turn on debugging and look at the output stream for errors.
export QT_DEBUG_PLUGINS=1
BTW, there's an HD version of qtdragon at github.com/persei802/QtDragon_hd that might give you a starting point.

Glad you got it working. must be because different paths are compiled in.
Could you post your compiled library binary?

You may need to get a later version on the 2.8 release, the Buster ISO I installed shows python-pyqt5 5.11

I am having the same issue with the Qtvcp widgets not appearing. I have followed the instructions from
here
and am getting the following error on both Strech and Buster (both these are installed from LinuxCNC ISO's)
Stretch has qt5 v5.7 and Buster has qt5 v5.11
If I remove the link from /home/phill/.designer/plugins/python/ designer does run but without the Qtvcp widgets.
Edit: I am running master from the Buildbot on both machines. I reverted the Stretch machine to 2.8 but it still has the same issue.
Edit2: Further searching shows that I failed to search correctly in the first place, renaming the file as suggested here has fixed it on both machines.
Perhaps a mention of this in the above doc would be appropriate.

Ok Phill I'll do that.
I'll be glad when we get to python3 only and avoid these problems.
