Off topic... but speaking of sync. This person has been up to! Compute module supports IEEE1588.

github.com/raspberrypi/linux/pull/5002/c...d95f7a1e64dd6d06ab7#

github.com/raspberrypi/linux/pull/5002

"Test & Performance:
We have tested the features in our lab and are able as a client to run at -7 intervals without significant performance impact. We are able to maintain synchronisation of the PHC within +/-10ns of its grandmaster PTP source and the system clock within 1-2us of the PHC."

How does that stack up against the EL6688 etc.

So if we want to deploy a file with our image, how do we do that?
Thinking of a .deb or wheel for vtk.

deb should be fine

if you have it hosted somewhere we can add a wget and dpkg-i into the uscripts file

Just about made a working "debian" fork of the full LXQT 1.1 source.  I imported the dsc files from a bleeding edge ubuntu ppa and fixed dependencies for bookworm. The workflow took a little figuring out!  Roughly speaking for 30+ packages...

cd package
gbp import-dsc ../package.dsc --create-missing-branches
gbp dch -S -a --debian-branch=$GBP_BRANCH && git commit --amend -C@{0} debian/changelog
gbp buildpackage -us -uc --git-ignore-branch --git-ignore-new

I should have the sid deb packages for arm64 done by the end of the weekend.

elovalvo's method to install qtvcp did not work for me, At least the install script ran perfectly instead of erroring. I was getting segmentation faults with qtplasmac, and other sample screens did not load.

 

The problem is related to the installation of lxde.

As suggested in
github.com/gnome-pomodoro/gnome-pomodoro/issues/344

you have to add in /usr/share/dbus-1/services/
the file named

org.freedesktop.Notifications.service

containing this
[D-BUS Service]
Name=org.freedesktop.Notifications
Exec=/usr/lib/notification-daemon/notification-daemon

Excellent!, that did the trick!
 

ftree, we need to create
/usr/share/dbus-1/services/org.freedesktop.Notifications.service
with that content above

The QTPYVCP guys have been kind to us and have contributed a .deb file for vtk and a simple test file. Downloading the .deb file now. 477mb does not lend itself to being shared on the forum!

My little SSD filled up so I had to blow away all my vtk stuff except the wheel but it was looking for a missing module when I installed with pip.

So am stuck on vtk at the moment. Odd thing is I got it working once before.
I need to find some time on my work PC to rebuild the image and regroup...

Cool!  Do you have a link?  I'll give it a try.
