For almost a week I can't set up Tesla K40 on CUDA. Currently I have 2 GPUs 1.Advanced Micro Devices, Inc. [AMD/ATI] Oland XT [Radeon HD 8670 / R5 340X / R7 250/350X] 2. Nvidia Tesla K40 active
After trying below steps I ended up with black screen:
1.Generated xorg.conf.new file by X configure in order to see current detected devices. When I generated I got the errors saying a. drm report modesetting isn;t supported b. Number of detected devices doesn't match number of created screens. However I still got the xorg.conf.new file therefore ignored errors.
- Installed Cuda toolkit by these commands
$ sudo dpkg -i cuda-repo-ubuntu1404_7.0-28_amd64.deb $ sudo apt-get update $ sudo apt-get install cuda
I made my own xorg.conf file in the /ect/X11 directory by referrring to generated xorg.conf.new file and https://devtalk.nvidia.com/default/topic/821158/setting-up-a-machine-with-a-tesla-k40-with-ubuntu-14-04-and-an-intel-on-board-graphics-card-solved-/ post (I had to change intel to radeon)
When I boot up there were only purple window.
5.After taking out Tesla K40 it booted up nicely. When I checked my xorg.conf file it's name was changed to xorg.conf.06252015.
I removed /usr/lib/x86_64-linux-gnu/xorg/extra-modules/libglx.so* file after reading a post on http://streamcomputing.eu/blog/2011-10-12/both-nvidia-gtx-and-amd-radeon-on-linux/ link(I didn't follow other steps except removing libglx.so).
After booting I am welcomed by black screen. Even CTRL-ALT-F1 is not working.
Because I can;t access my ubuntu 14.04 I can't show you my xorg files.
