Posted 5388 days ago by Profile RAMen
After a 3 day struggle to get the GPU working correctly I attached to GPU Grid and now all WU error out.

This is the Machine

BOINC version 6.6.37
have tried 6.6.20, 6.4.5 same results

Nvidia Drivers: 180.11 (Ubuntu recommended)
stable and reload on reboot

have tried 185 drivers but drivers disappear on reboot and reverts to Xorg 1024 x 768




All WU error out with this or similar message"


<core_client_version>6.6.37</core_client_version>

I have a solution to the no CUDA devices found:

as root (su command) issue chmod a+rw /dev/nvidia*

stop the boinc client before issuing the command

sudo /etc/init.d/boinc-client stop (dont forget to restart)

This seems to work I dont know why.. the command has to be issued each time you reboot..
