Fedora 30 5.1.16-300.fc30.x86_64
Boinc 7.14.2 x86_64-pc-linux-gnu
NVIDIA-SMI 430.34 Driver Version: 430.34 CUDA Version: 10.1
GeForce GTX 960

boinc --detect_gpus creates the file coproc_info.xml which says I have
cuda>1
name>GeForce GTX 960
ram>1.9gig
etc.....
stdoutgpudetect.txt says Missing start tag in cc_config.xml

If I systemctl start boinc-client.service and run boincmgr I don't get any GPU work
If I cd /var/lib/boinc and nohup boinc & I get GPU work.
What's the fix?
Thanks

I am guessing that manually starting boinc (user? root?) is different than starting via the service.

I see "boinc" as owner for just about all in var/boinc but
"root" seems to be owner of script in /etc

How does your service compare to mine?

Matches 1:1
I just changed the "User" to root and ran restart. Seems to work.

Huge security risk running BOINC as root. I haven't used GPU for crunching for many years but IIRC boinc needs to be added to the GPU user group?

I've found this. But, how it's possible to use gpu then, without security risks? If it can't access group 'video', than what should it do?

Risk is everywhere. Some people just ignore it and have fun for as long as it lasts. Others minimize the risk and then decide whether the minimum level is acceptable or not. Crunching with boinc as member of video group is less risky than running the client as root, IMHO. Yes, somebody might turn my webcam on and yes that might cause me to lose my virginity but I'm 67, maybe it's time.
The link you gave seems to suggest the risk can be reduced even further but I don't understand it.

I don't understand it.

I' don't understand how one can add one group to another group.

sudo usermod -a -G video boinc

You're not adding one group to another group. You're adding a user named boinc to the group named video.

Jordan gave the right command but IIRC the syntax is incorrect. If his version does not work then try

sudo usermod -a boinc -G video

Do "man usermod" for details.

Jordan

My name is Jorden, but since no one cares enough anymore to see if they spelled that correctly - you just showed that - I call myself Jord. Which people then still bastardise into the weirdest of spellings and adaptions.

I did a search on the forums and picked it up from another thread. Shrug, go blame them if it doesn't work.

Take a look at my name and then tell me about it, Jurgen. I'm tempted to just change it to something easy like Bob. Anyway, how about we just call each other "J", OK?

I saw it too. Methinks they mangled the parameters the way they mangle our names. Those silly name manglers huh?

If you had provided a URL to the forum where you allegedly found the command, I would give them the same advice.... do man usermod. As for blaming them.... since when did blame enter the pic? I thought we were all just helping each other out here for free. You mean Toddler Tyrant needs to fire somebody over this? OMG, what did we start here? OMG^2... you going be fired?

BTW, I pre-shrugged this whole thing before you shrugged.
