Hello world, I am working with a laptop which has GeForce GTX 980M The laptop is running a newly installed copy of Ubuntu 14.04 server. After I installed Ubuntu, the laptop behaved well. It responded to ssh login in under a second. Then, I followed the instructions I found here: http://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html I downloaded this file: -rw-rw-r-- 1 dan dan 2013382446 Jun 7 19:54 cuda-repo-ubuntu1404-7-5-local_7.5-18_amd64.deb I ran these shell commands: sudo dpkg -i cuda-repo-ubuntu1404-7-5-local_7.5-18_amd64.deb sudo apt-get update sudo apt-get install cuda Installation succeeded with no problems I could see. I rebooted. Now when I ssh into the laptop, the laptop needs about 60 seconds to log me in. Are any other Ubuntu people seeing this bug?
