I have two GPU's (NVIDIA RTX 2060 and a NVIDIA GTX 1660 ti under openSuse Tumbleweed Linux ) that i used to run seti and it worked very well, now i am running Milkyway at home and that will still use the GPU's
I had been trying to run 1 monitor per gpu but could never gt it working, so I reconnected my monitors to a single GPU and got both my screens working, But there is another issue.
On boot ,as a regular user, clinfo shows no platforms, but if i then run clinfo as root it shows both GPU's ok, and after that if I again run clinfo as a regular user it shows shows both GPU's.
This is repeatable and happens at every boot.
So, running clinfo as root changes something, i dont know what tho.
If i dont follow the above procedure boinc doesnt see either GPU.
If anyone can explain this I'd be deeply appreciative.
TIA

Strange one. I have never had any issue with clinfo showing me all my cards no matter which user is logged in. But I run the BOINC client as user. Could the problem be that you are using the distro version of BOINC which installs BOINC as a daemon. That means you as user don't have access to BOINC which is in the BOINC and video user groups.

When you access as root, then you have access to those restricted groups also. You could try adding yourself to the BOINC and video user groups and test clinfo again.

You could run groups from the command line to see what groups your user belongs to. Then add your user to both boinc and video for the boinc daemon service.

useradd  -a -G boinc video {username}

where {username} is your logged in user name. Then try accessing clinfo again and restarting BOINC and see if the gpus are detected at startup.

You do have <use_all_gpus>1</use_all_gpus> in your cc_config.xml file . . . . right?

Perhaps running clinfo under root triggers some additional service (daemon on Linux perhaps) launch.
And simple user not allowed to start it so clinfo just fails to find anything.
Try to check what new processes are running after clinfo invocation under root and manage to run them in startup script.
