In order to install the nvidia graphics drivers on BT5R2 you need to enter the following into a terminal prompt while X is not running.
This process is slightly longer than in BT5 because of nouveau drivers being loaded.
First you need to disable the nouveau drivers, which can be done thus:
Now add the following 6 lines at the end
Finally reboot and nouveau drivers will now be disabled.
Then you need to prepare the kernel sources if you have not done so already by:
Please remember to copy and paste these commands into your terminal prompt as formatting can make long lines wrap over into two or more lines !
apt-get install linux-source
cp -rf include/generated/* include/linux/
Then for 32bit BT5: following the prompts
chmod +x NVIDIA-Linux-x86-295.20.run
Or for 64bit BT5: following the prompts
chmod +x NVIDIA-Linux-x86_64-295.20.run
And that's it, you should now be able to restart, and startx enjoying the full glory of BackTrack at the full resolution offered by your graphics card and monitor.
