I'm trying to get my EVGA 780 to work on Linux Mint 17.1 (XFCE if that matters), so basically ubuntu. But despite me trying everything under the sun I get the "nvidia drivers present but no gpus found" I installed the boinc nvida patch, the mods out there.. different drivers, etc. I keep seeing this a common issue with drivers above 331.. but half the drivers available before that don't work with the 780.
 
That PG challenge starts soon and I don't wanna my heavy hitter out before it starts 
 
I also tried use all gpu in config, I've also tried manually adding a coprocessor, but none of my settings seem to make a difference, anybody know what drivers/settings/installs are needed for this to function? I might just be mucking everything up myself.. not sure what needs to be in the coproc settings either.. 

I'm setting up a bunch of p2pools (P2Pools.com) for coin mining and just need a bulk of my systems to be linux now.. the windows builds are all sh*te.. max out at 1k difficulty and other nonsense (but i think that's the windows architecture causing a prob)..
 
anyway.. is it just ubuntu? I got no problem switching to something else.. Debian perhaps?

lol.. which one? no seriously, i have tried a few but is there one you can suggest? Some sites say to use the build on boinc, some say to use like the one here -> https://launchpad.net/~pkg-boinc/+archive/ubuntu/ppa There's so many floating around I might have missed the good one somewhere.. 

Also, is there a driver I should stick with to continue testing. right now I'm using 331.113 updates with boinc and cuda and opencl id and all the other 331 settings nonsense and etc. But it does say in the boinc startup no opencl id? So i dunno..

/usr/lib/i386-linux-gnu/libcuda.so.1
/usr/lib/i386-linux-gnu/libcuda.so.331.113
/usr/lib/i386-linux-gnu/libcuda.so
/usr/lib/x86_64-linux-gnu/libcudart.so.5.5
/usr/lib/x86_64-linux-gnu/libcuda.so.1
/usr/lib/x86_64-linux-gnu/libcuda.so.331.113
/usr/lib/x86_64-linux-gnu/libcudart.so.5.5.22
/usr/lib/x86_64-linux-gnu/libcuda.so
 
and 
 
/sbin/lsmod | grep nvidia
nvidia 10744943 40
drm 303102 3 nvidia
 
but no nvidia.ko
 

I will give that a try, I was just going through that same process of trying to install drivers manually right now.. but xorg won't stay dead, won't exit to terminal only, etc.. xfce might be part of the problem but damn! why has nvidia ignored this issue for what I can tell is several years... back when the software versions were in the 200's..

truth! i used to be that way too.  lol.. but I switched to using gpu's for this and my consoles for gaming 

So is this more of a driver/cuda/opencl issue rather than a boinc issue? no one really seems to be too sure, most answers seem to lay with manually installing the drivers.. and then sometimes boinc, but none say which is the culprit.. 
 
anyway, I'm gonna try another OS.. I like mint but it's just an ubuntu clone anyway.. isn't ubuntu and old clone of debian too.. yeesh.. Regardless I'm gonna give debian kde a try (gnome sucks up too much resources everytime i use it).. that's why i liked xfce.. But i've seen a few success stories there.. and their deb package installers and ppa's for drivers and boinc are more up to date too.. 
 
What distros do you guys use?

For what it's worth, I'm running a gtx 760 on mint 16 using the 319 drivers. It just kind of worked without any hassle.

load balancing can be quite hypnotic sometimes and 1.2 GB used while processing! I'm happy with that, time to load this beast up..
 

 
And for some reason it's processing opencl and cuda simultaneously.. but I'm not seeing a real dip in power.. not one to justify leaving it off yet.. it was doing poem and gpu long task, maybe 1hr longer than normal on the cuda long gpu grid task..
 
weird.. gonna need some testing

What happens if you follow the instructions from this link https://sn0v.wordpress.com/2012/12/07/installing-cuda-5-on-ubuntu-12-04/
 
and did you create a softlink by chance?

Great link!  Really helped me out to cleanup the mishmash of tactics I originally used to get nvidia gpus working on my 4p.
Finally got BOINC to recognize CUDA support.
 
You guys are very helpful to those of us who are not so linux inclined.

A non-maskable interrupt (NMI) is a hardware interrupt that cannot be ignored by standard interrupt masking techniques in the system. It is typically used to signal attention for non-recoverable hardware errors. (Some NMIs may be masked, but only by using proprietary methods specific to the particular NMI.)
 
add ‘nmi_watchdog=0 pcie_aspm=off nohpet’ to kernel param at boot like 
 

kernel /vmlinuz-2.6.9-78.0.8.EL ro nohpet root=/dev/VolGroup00/LogVol00 nohpet nmi_watchdog=0 pcie_aspm=off  at /boot/grub/grub.cfg or grub.conf
