以下为在ubuntu10.04下install cuda 3.2的个人总结：
section 1:device driver installation
step 1:the Nouveau kernel driver is currently in use by your system,it’s uncompatible with the Nvidia driver,you must disable Nouveau driver before proceeding.For some distribution ,Nouveau can be disabled by adding a file in the modprobe configuration directory.The Nvidia driver recommand to add nvidia-insatller-disable-nouveau.conf to “/etc/modprobe.d”.The following two lines will be added in the nvidia-insatller-disable-nouveau.conf.
“blacklist nouveau”
“options nouveau modeset=0”
step 2:If you have rebooted,the Nouveau may be enabled for other reasons,such as being included in the system initial ramdisk or initramfs or your x configuration file.In the terminal,input"gedit /etc/modprobe.d/blacklist.conf",add the following statements at the bottom and reserve it.
diable the nouveau driver to gpu
“blacklist vga16fb”
“blacklist nouveau”
“blacklist rivafb”
“blacklist nvidiafb”
“blacklist rivatv”
and then input “sudo update -initramfs -u” to update the newest initramfs.
step 3:input “sudo apt-get --purge remove nvidia-*” to clear all the nvidia driver correlated to the older version.
step 4:input “sudo gedit /etc/default/grub”,when you look the GRUB_COMLINE_LINUX_DEFAULT=“quiet splash”,replace the “quiet splsh” with “text”.And then input"sudo update-grub".The system will boot in the form of text other then visual windows. and then reboot you system.
step 5:input “sudo apt-get --purge remove xserver-xorg-video-nouveau”.
step 6:input sh Nvidia-linux-x86-64.run.
section 2:cudatoolkit 3.2 installation
step 1:cd the directory of the cudatoolkit3.2.run
step 2:sh cudatoolkit3.2.run, install path(default /usr/local/cuda),just follow the default way.
step 3:make sure your PATH includes /usr/local/cuda/bin.how to do it ? input “export PATH=/usr/local/cuda/bin:$PATH” or open the file of environment in the /etc/environment.And then append the PATH with"/usr/local/cuda/bin".so the final PATH is :PATH=“/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/cuda/bin”. The former way is temporary solution,it take effect in the current shell.if you start a new shell,it doesn’t work.so i strongly advise to use it in next way.Another apect is to make sure your LD_LIBRARY_PATH for 64-bit linux distribution includes /usr/local/cuda/lib64:/usr/local/cuda/lib. how to do it ? one method is to input “export LD_LIBRARY_PATH=/usr/local/cuda/lib64:/usr/local/cuda/lib:$LD_LIBRARY_PATH”.another way is to open the etc/ld.so.conf,append with “/usr/local/cuda/lib64 or /usr/local/cuda/lib”.finally,input “ldconfig” and update the /etc/ld.so.cache.there is no better way than the second method.it 's permanent.
section 3:gpucomputingsdk 3.2 installation
step 1:cd the directory of the gpucomputingsdk3.2.run
step 2:sh gpucomputingsdk3.2.run.install path(default ~/NVIDIA_GPU_COMPUTING_SDK).if you install the cudatoolkit successfully, the it will show “located CUDA at /usr/local/cuda,if this correct,choose the default below.enter cuda install path(default /usr/local/cuda),configurating sdk makefile (/root/NVIDIA_GPU_COMPUTING_SDK/C/common/common.mk)”.
finally, success of installation above application software.if you want to return the visuable desktop,one way is to input “etc/init.d/gdm start” lead you to your graphic window ;another way is to input “sudo gedit /etc/default/grub”,when you look the GRUB_COMLINE_LINUX_DEFAULT=“text”,replace the “text” with “quiet splash”.And then input"sudo update-grub".
