Has anyone successfully installed CUDA 7.5 on Ubuntu 14.04.3 LTS x86_64?
The installation of CUDA is little a bit tricky. I've followed the following steps and it works for me. You can refer to this link also.
Confirmation of the environment:
lspci | grep -i nvidia
(Confirm that the information of NVIDIA's board is displayed)uname -m
(make sure that it is a x86_64)gcc --version
(make sure it is installed)
Installation of CUDA –
Download
cuda_7.5.18_linux.run
file from https://developer.nvidia.com/cuda-downloadsRun the following commands:
sudo apt-get install build-essential echo blacklist nouveau option nouveau modeset=0 |sudo tee -a /etc/modprobe.d/blacklist-nouveau.conf sudo update-initramfs -u
Reboot computer
At login screen, press Ctrl+Alt+F1and login to your user.
Go to the directory where you have the CUDA driver, and run
chmod a+x . sudo service lightdm stop sudo bash cuda-7.5.18_linux.run --no-opengl-libs
During installation:
- Accept EULA conditions
- Say YES to installing the NVIDIA driver
- Say YES to installing CUDA Toolkit + Driver
- Say YES to installing CUDA Samples
- Say NO rebuilding any Xserver configurations with Nvidia
Check if
/dev/nvidia*
files exist. If they don't, do the followingsudo modprobe nvidia
Set Environment path variables
export PATH=/usr/local/cuda-7.5/bin:$PATH export LD_LIBRARY_PATH=/usr/local/cuda-7.5/lib64:$LD_LIBRARY_PATH
Verify the driver version
cat /proc/driver/nvidia/version`
Check CUDA driver version
nvcc –V
Switch the lightdm back on again
sudo service lightdm start
Ctrl+Alt+F7 and login to the system through GUI
Create CUDA Samples, Go to
NVIDIA_CUDA-7.5_Samples
folder through terminal, then run following command:make cd bin/x86_64/linux/release/ ./deviceQuery ./bandwidthTest
Both tests should ultimately output a 'PASS' in terminal
Reboot the system
There are two ways to install suiting CUDA-driver (for Optimus and else built-in graphics-chipsets on hybrid mainboards) - the first described here is the easiest and the second description is more cumbersome but effective too :
A)
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-355 nvidia-prime
sudo reboot
B)
Description of method B is here, but already older (explained by user dschinn1001) - this method B is more humblesome and can be risky, but not harmful. :
How can I Install Nvidia Driver GT 520 and Cuda 5.0 in Ubuntu13.04?
The beta-driver-package for Nvidia to download for Linux is here :
http://www.nvidia.de/object/cuda_1_1_beta.html
Method A is more simple, but not clear, how it interacts with xscreensaver and method B is older, but the driver-package is updated too in recent time, and after method B is done, it should work better with xscreensaver conditioned that xscreensaver is installed. (I tested method B on 13.10 and this was working very good, even with xscreensaver. And I think the rest of this thread is up to the hardware.)
In addition and in reference to bumblebee with Optimus-graphics-chipsets these adjustments for bumblebee are necessary too :
