Blank Screen Backtrack 5 [NVIDIA]

Many Backtrack’s user have a same problem about the GUI. One of them is blank screen when using startx and can’t load module. If you read the post before, Solve Blank Screen when Using Startx, and it can’t solve your problem maybe the problem is in your VGA card. If you’re using NVIDIA this is the solution of
blank screen on Backtrack 5.

First of all run this command

apt-get install linux-source-$(uname -r)

then

prepare-kernel-sources

open the grub.cfg

nano /boot/grub/grub.cfg

find this line

menuentry 'Ubuntu, with Linux 2.6.38' --class ubuntu --class gnu-linux --class gnu --class os {
        recordfail
        insmod ext2
        set root='(hd0,6)'
        search --no-floppy --fs-uuid --set bb09766b-aa12-4cca-ac61-a29108d69579
        linux   /boot/vmlinuz-2.6.38 root=UUID=bb09766b-aa12-4cca-ac61-a29108d69579 ro   text splash nomodeset vga=791
        initrd  /boot/initrd.img-2.6.38
}

change vga=791 to nouveau.modeset=0. This is the final grub.cfg

menuentry 'Ubuntu, with Linux 2.6.38' --class ubuntu --class gnu-linux --class gnu --class os {
        recordfail
        insmod ext2
        set root='(hd0,6)'
        search --no-floppy --fs-uuid --set bb09766b-aa12-4cca-ac61-a29108d69579
        linux   /boot/vmlinuz-2.6.38 root=UUID=bb09766b-aa12-4cca-ac61-a29108d69579 ro   text splash nouveau.modeset=0
        initrd  /boot/initrd.img-2.6.38
}

Then you must download NVIDIA driver. Search on the Internet and download it. After you download it run the driver like this

./your-NVIDIA-driver --kernel-source-path='/usr/src/linux/'

Hope your problem solved ;-)
