AGILE is such a completely worthless software methodology. All it produces is perpetually broken (*&^)(*&)(*&.

KDE Neon 5.8.whatever 64-bit. Due to the latest INTEL CPU bugs getting much press and all of the claims the Linux world has fixes for them, I applied updates to all my machines. I actually have 2 running this configuration and they both have the same NVIDIA card with the same driver installed. The latest Linux-Lite is on the third machine running Boinc with NVidia.

My 6-core AMD no longer starts Boinc.

I did find this discussion https://boinc.berkeley.edu/dev/forum_thread.php?id=11230 but it doesn't seem to be the same problem.

This part of syslog may be Red Herring.

What strikes me as odd is trying to start from the command line.

Prior to the updates the GPU was always found. There were no errors reported with the update

Updates were applied on the same day to the quad-core I7 with the same NVidia card and driver. All is well. That is why I was intrigued by the ureadahead message in syslog since this appeared initially to be a Boinc only problem, but other message threads seem to indicate that has nothing to do with the problem. Not finding the GPU means something bad happened and went un-reported during update process.

Any thoughts?

Royally weird.

I went through the update process again from the command line. Zero updates were applied. Rebooted yet again and this time boinc manager started.

Seriously weird.
