Renamed all boinc_client in Rc0...Rc6 from "01" to "91" which forces it as the last script to run but that did not fix the problem

I can put a sleep 300 or so into the boinc_client script but I think that blocks. Since this is the last script anyway, maybe that is ok?

There are five RX560 and it seems I need about 4-5 minutes or so to allow 18.04 to stabilize.

I did not see an "autostart" at ./configure so I am not running that version with the autostart.

Jord's task scheduler worked fine in windows on my windows system but this is Linux and I am no expert on Linux.

This was asked three days ago in the GPU area: Is there a way in Linux Mint 19.1 to delay boinc start at boot?

I've asked the developers to look into it in #3150: could you nip over to the other thread and answer Germano's questions, please? He's a member of the development group who specialises in packaging BOINC for Linux distros.

Wanted to update this thread with what was learned at the GPU forum and also at the AskUbuntu community

In the file /lib/system/system/boinc_client.service

replace

After=network-online.target

with

After=multi-user.target

That file might be in slightly different location depending on flavor of Linux.
Only make the change if GPUs are not being recognized on first power up but are recognized if boinc is restarted.
