I really need your help on this. I have been trouble shooting my computer issues for past 2 months now. what happened was I have a sandy bridge/z77 combo that i used over past 3 years that worked fine for CUDA, etc. and i decided to upgrade to new z97 and haswell combo during Xmas time. i also installed ubuntu 14.04 and got gtx 970. i’m a researcher and do not play games i need cuda and nothing else running on ubuntu. however, i had all sorts of problems with these boards. i can’t pin point where things are going wrong. is the new h/w? ubuntu not compatible? cuda driver not working? i think it really boils down to nvidia driver. when i install ubuntu via intel iGPU, everythign is working. so i plug in gtx 680, boot, it still comes up but driver not the latest. so i installed cuda 6.5 and lately 7.0rc and this is when things go to hell. upon passing bios screen it seems like grub or something is doing some sort of a splash screen but it goes blank. i have tried different cards, 680, 780, 970 and none of them. work.
i want all 3 of these in one MB so that i can profile all 3 of them. so i got a MB that can do 4 PCIE such as asus z97-ws, gigabyte gaming gt, and lastely asrock oc formula. i eneded up retruning all of them except asrock oc formula. this was working perfectly fine for past 5 days and one day i’ll get this black/blank screen again. so i unplugged all GTXs and boot from intel and seems to be fine. so i uninstalled nvidida driver and reinstall to new driver 346.75? i think then plug in 1 GTX and it comes up fine. but i check cuda and it says cuda is not found. i must have deleted something when i purged nvidia. so i in stall cuda 7.0rc and it says it still doens’t work.
i tried so many variations now. the problem is there when i do 7.0rc.deb install which contains the drive.r when i install driver separately and cuda separtely cuda doens’t work. so nothing works. what am i doing wrong? do you have these issues. should i return all these MB and get a more mainstream MB with 2 PCIE slots such as asus z97-a, extreme4, etc.?
do you use z97/hasweell combo that works with ubuntu 14.04 and latest cuda? i really really can’t spend any more time on this i have paper deadlines coming up and this is causing major crisis here. i can use any help right now. i just want something that works and stable. i’m lost at this point… thanks a lot
