I got a very funny behaviour. Seems some kind of bug.

I configured my GRUB to start up in text mode and the result is that BOINC dind't recognize my GPU tasks, but Einstein@home did.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash text"

I started 'startx', restarted the service on boinc and this task broke:

But the other one keeps running.

Another weird thing is that the Einstein task keeps running normally all the time.

Is it worth I report more info to try to find what happened?

This text can mean two things. Either you have to jump into the water, or you have to throw your computer into the water. :-)

Welcome to the wonderful world of linux. :-)

...where people complain 50% of the time about proprietary drivers, and 50% about open-source ones. :)

Einstein uses CUDA3.2 and GPUGRid uses CUDA3.1. Might make a difference.

Not sure it's the driver.
I think it has something to do with Graphics server on linux, because I have the monitor conected to the card not to the on-board card (something I'll do later)

If you want me I think I can reproduce the error. If not, I just forget about it.

Confirmed everytime I start the graphical server I get one unit broken. if I don't start it, Gpugrid units never start althougt Eintein units do.
Could be CUDA as Skgiven says or the way units are started.
Once they start there's no problem.

No more splash! I love xorg, such a stable system!
