I'm new to BURP and would like to participate, but I get "computation error". I saw another post here which talked about GPU, and also this one which made me create the "native" directory and restart, but I still get the same error.

I'm on Ubuntu 16.04 LTS and installed BOINC from the Ubuntu repositories.

I have a HP Envy laptop with a dual graphic card Intel/Nvidia (a pain in the butt on Linux), so my first question is: do I need to use the Nvidia card (I can only select one in a login session on Ubuntu, to change the active card I have to log out and in again).
My Nvidia card has to be rather weak because Blender renders faster on CPU than on GPU, so I very rarely use the Nvidia card (it heats up also and sucks lots of battery). So, can I leave my Intel card active and still participate in BURP?

And apart from that, are there any other solutions to the "compuation error" problem?

Hi. If you use the "native" you must have a blender from the repository ( apt-get install blender ). Try to follow the instructions. [FAQ] Portability - Linux

I already have blender installed, that can't be it, I think.

Since the "native" folder didn't help, maybe I should just remove it again? And the problem is elsewhere?

I don't think these apply, I don't see any error message concerning libraries.

In the event log I see
"No usable GPUs found" (I have a hybrid graphics laptop and am struggling to get nvidia working), is this related?

Your latest few errors were not from native mode, you should see a line saying something along "Skipping preloader" when in native mode.

Do you mean in the event log? Or where should I see this line? (I use the graphical manager, not command line).

I now tried this:

sudo touch /var/lib/boinc-client/projects/burp.renderfarming.net/native

(inspired by this more recent post concerning Linux).

For the moment the BOINC event log says for BURP: "0 new tasks", so I'll probably have to wait to find out if this works, until a suitable project comes along...
