Ubuntu 14.04 LTS is out, loads of new features have been added. Here are some procedures I followed to install CUDA 6.0 on my DELL Inspiron.
First of all, Ubuntu need to be installed successfully, and the
necessary libs are also need to installed:
sudo apt-get install build-essential gcc-4.4 g++-4.4 libxi-dev libxmu-dev freeglut3-dev
Things you need to have before start the installation
process:
1. Latest NVIDIA graphic driver
(NVIDIA-Linux-x86_64-331.49.run)
2. CUDA 6.0 installation file (cuda_6.0.37_linux_64.run)
Now let's install the graphic driver
If you’re not sure your system type, press Ctrl+Alt+T to open
terminal and run:
uname -m
1. Find out your graphics card model
Use the lspci command to find out the model of your graphics
card
$ lspci -vnn | grep -i VGA -A 12
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GT218 [GeForce 210] [10de:0a65] (rev a2) (prog-if 00 [VGA controller])
Subsystem: ASUSTeK Computer Inc. Device [1043:8416]
2. Find out the right driver version for your graphics card
Visit http://www.nvidia.com/Download/index.aspx
Fill in the details about your graphics card and system and then
click Search. On the next page, it should tell you the correct
driver version with a download link and additional information.
For the above GeForce 210 card, it showed 331.67 as the correct
driver which can be downloaded from the website. However we shall
install the drivers from ppa to make things easier.
3. Setup the xorg-edgers ppa
The xorg-edgers ppa provides the very latest nvidia drivers. Run
the following commands to set it up.
$ sudo add-apt-repository ppa:xorg-edgers/ppa -y
$ sudo apt-get update
Now the ppa is setup and the package information is also updated.
4. Install the driver
Either you can install the driver directly by installing a single package containing "nvidia" and the major version number ( 173, 304, 310, 313, 319, 331, 334 or 337).
# 331 driver
$ sudo apt-get install nvidia-331
# 334 driver
$ sudo apt-get install nvidia-334
# install the latest version
$ sudo apt-get install nvidia-current
Or you can enable it from the "Additional Drivers" section. This is different on different Ubuntu flavors.
5. Verify the installation
The last thing to do is verify that the nvidia drivers are loaded
and working. Run the lspci command again and this time the kernel
driver should show nvidia
$ lspci -vnn | grep -i VGA -A 12
Check the last line which says "kernel driver in use: nvidia". This
shows that nvidia drivers are now in action. Also check hardware
acceleration with the glxinfo command
$ glxinfo | grep OpenGL | grep renderer
OpenGL renderer string: GeForce 210/PCIe/SSE2
The OpenGL renderer string should be anything other than "MESA". Then it indicates that the hardware drivers are being used for hardware acceleration.
6. Nvidia settings tool
Nvidia would install a gui tool called "Nvidia X Server Settings" somewhere in the menu. It can also be launched from the command line using the command "nvidia-settings". The tool shows miscellaneous information about the graphics card and the monitor connected, and also allows to configure various options.
7. Removing the drivers
Incase anything goes wrong after the installation, like you are not
able to boot Ubuntu, then try removing the Nvidia drivers.
Boot into the recovery console from the grub menu and then issue
the following commands
# remount root file system as writable
$ mount -o remount,rw /
# remove all nvidia packages
$ apt-get purge nvidia*
Additional Notes
Many tutorials out there talk about blacklisting the nouveau driver. This is no longer necessary, since the nvidia driver would blacklist nouveau itself. This can be verified by checking the contents of nvidia driver files in the the modprobe.d directory.
$ grep 'nouveau' /etc/modprobe.d/* | grep nvidia
/etc/modprobe.d/nvidia-331_hybrid.conf:blacklist nouveau
/etc/modprobe.d/nvidia-331_hybrid.conf:blacklist lbm-nouveau
/etc/modprobe.d/nvidia-331_hybrid.conf:alias nouveau off
/etc/modprobe.d/nvidia-331_hybrid.conf:alias lbm-nouveau off
/etc/modprobe.d/nvidia-graphics-drivers.conf:blacklist nouveau
/etc/modprobe.d/nvidia-graphics-drivers.conf:blacklist lbm-nouveau
/etc/modprobe.d/nvidia-graphics-drivers.conf:alias nouveau off
/etc/modprobe.d/nvidia-graphics-drivers.conf:alias lbm-nouveau off
Note that the files "nvidia-331_hybrid.conf" and "nvidia-graphics-drivers.conf" have blacklisted nouveau.
To check information about the nvidia driver module, use the commands lsmod, modprobe and modinfo
# check that nvidia kernel module is loaded or not
$ lsmod | grep nvidia
nvidia 10699336 49
drm 302817 2 nvidia # find the real name of the nvidia module
$ modprobe -R nvidia
nvidia_331 # details about the nvidia_331 module
$ modinfo nvidia_331
filename: /lib/modules/3.13.0-24-generic/updates/dkms/nvidia_331.ko
alias: char-major-195-*
version: 331.67
supported: external
license: NVIDIA
.....
The kernel module file for the nvidia driver is located at "/lib/modules/3.13.0-24-generic/updates/dkms/nvidia_331.ko".
Note that it is a "dkms" module which means, its loaded dynamically. Due to this the grub screen, the Ubuntu/Kubuntu splash screens would have a low resolution since at that time the nvidia drivers are not in effect, and whatever resolution is available via the VESA extensions, are used.
8. Another Option
$ sudo apt-get update
$ sudo apt-get install nvidia-340
9. Install CUDA
nvidia-cuda-toolkit
