Just installed a dual boot 14.04 lts, 64 bit and used the locutusofborg agent 7.4.13. System crashed several times, and now see the agent only recognizes 1.95gb physical memory, so suspect the second strip went into graveyard state. At any rate, see moving graphics for faah and fahv sciences. Can close the graphics repeatedly and reopen. The fahv graph resizes with the window but the faah just stays in a fixed size, hopping around in a black window if maximized.
Pulled some mcm work and see the graphics windows open ever so briefly, barely a blink of an eye. This repeats on each 'show graphics' button hit. Revisiting faah and fahv, they appear fine. Nvidia card, this being an out of the box all defaults lts install, which immediately upgraded to the 3.13.0-35 generic kernel. Now need to run some diagnostics to find the broken strip, if it is, and a replacement. Maybe just a reseating is needed. The nvidia card could be stealing the system ram too which is why only 2gb is seen, but that is entirely off topic. |

I just posted another possible solution to a thread in the Uncovering Genome Mysteries forum.
Set the s-bit on the graphics executable so that it runs as boinc:boinc - that seems to work on Ubuntu 14.04, and I see no reason it wouldn't work on other versions. Assuming you've installed a package version of BOINC in the "standard" place... sudo chmod +s /var/lib/boinc-client/projects/www.worldcommunitygrid.org/wcgrid_mcm1_gfx* Now you won't have to run things as root(!) (The only problem with this is that that if the graphics program gets lost and fetched again, you'll have to set the s-bit again...) |
