Hi, I'm using Ubuntu 16.04 LTS, with an Intel Celeron CPU and Intel Bay Trail graphics. I've been trying to install and run BOINC every way I can think of, but any time I attempt to run the client via terminal (various methods), I get this message:

I've been searching these forums and Google for about an hour and tried about everything I've seen, like updating drivers and restarting the Boinc client but nothing seems to be working. It may be of use to note the manager works just fine. Any help? Thanks!

These drivers you installed, do they have any OpenCL component?
You may want to try https://software.intel.com/en-us/articles/opencl-drivers#latest_linux_driver from Intel themselves.

Although I wonder if there are projects already that have applications that use the Intel GPU under Linux. And I also wonder if the GPU in the Celeron N2830 is even OpenCL compatible.

I'm not quite sure that you have installed boinc correctly, or you may be running the client incorrectly and the GPU error is a result of that.

You should not normally need to run the client from a terminal window, as the boinc repository install should work normally.

Ubuntu 16.04 boinc source indicates 7.6.31 is the current source.

I presume you installed "boinc" (which includes the manager AND the client)

Please remove any attempts at installing boinc other than via the repos.

When requesting help on these forums. asks for some details of the event log, as viewed by the client, that probably will be revealing.

Good luck.

Not sure, downloaded OpenCL successfully from your link though. Couldn't find anything about my GPU being compatible either, but I assume it is.

Yes, I am sure I downloaded both the client and manager. Tried to remove previous attempts and reinstalled using package manager. Here's the results from attempting to run it using "boinc" again:

Previously the manager was having issues (said it couldn't find core client) but now it's doing something (screen says downloading work from server), so there's progress.

EDIT: The manager is working just fine now, and it's currently doing some work. Thanks everybody!

OK great - do not run boinc client in a terminal window via "boinc" - doing so will start a second copy of the client which is likely to be confused about where the boinc data directory lives and fail GPU detection.

If you want to start the boinc manager from a terminal window, then may i suggest (*)

man boincmgr   
boincmgr &


If you must stop / start the boinc client from the command line, at 16.04 then the correct systemd stylee

man sudo
man systemctl
sudo systemctl stop boinc-client.service
sudo systemctl start boinc-client.service



(*) - man - short for manual, is the first linux command to use, and i find if i don't use man command, before command, penguins may display strange behaviour.
