I’ve built a new computer with an i7-4770K processor (LGA1150) and a GEFORCE GTX Titan GPU. I’ve installed Ubuntu 12.04 64 Bit with no problems. At this point I have not downloaded any drivers for the GPU. (It is my understanding that a driver will come with the CUDA download) Then, in Terminal, I performed the checks for CUDA compatible GPU, supported Linux, and gcc. All look correct.
Then I did the nvidia uninstall:
got a response “No such file or directory” as expected because I had not downloaded a driver.
Next it was not clear to me if I had to enable armhf, but I tried it both ways. When I did try it, as written in the CUDA Toolkit Documentation, I got a Permission denied message to the echo command. So, I switched to super user, and reentered the command at the # prompt. I assume it worked, there was no error message, just another # prompt. Then I entered:
# apt-get update
Many things scrolled by, there were some “Failed to fetch” warnings and ended with “E: Some index files failed to download…” Assuming it worked or that I did not need to enable armhf, I proceeded:
I downloaded the DEB file into the Downloads directory, exited super user, and changed directories to the Downloads directory. I entered the dpkg command, and got an “OK” from that. Then I entered:
$ sudo apt-get update
and again many things scrolled by ending with a lot of “Failed to fetch” warnings and “E: Some index files failed to download…”
I continued as if this were normal and entered:
$ sudo apt-get install cuda
Got the message:
“The following packages have unmet dependencies:
cuda : Depends: cuda-5-5 (= 5.5-22) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.”
I don’t know what to do from here.
Is there better documentation somewhere?
Can someone help?
