Install NVIDIA Drivers On Kali Linux

This document explains how to make use of NVIDIA video hardware and install the drivers on a Kali Linux system.

The first step is to fully update your Kali Linux system and make sure you have the kernel headers installed 

apt-get update && apt-get install -y linux-headers-$(uname -r)

Next, download the latest NVIDIA driver for your architecture and video card here. To locate your NVIDIA card model, execute the following command.

root@kali:~# lspci | grep -i vga
02:00.0 VGA compatible controller: NVIDIA Corporation GT218 [GeForce G210M] (rev a2)
03:00.0 VGA compatible controller: NVIDIA Corporation C79 [GeForce 9400M G] (rev b1)

The next step is to disable the nouveau driver. Nouveau is a open source NVIDIA driver project, however it lacks the 3D graphics acceleration needed to run Cuda pentest tools.

sed 's/quiet/quiet nouveau.modeset=0/g' -i /etc/default/grub
update-grub
reboot

Once the system has rebooted and you are looking at the GDM login screen, press CRTL+ALT+F1 in order to get to a TTY, which will be a black screen with a login prompt. We need to login as root and stop the gdm3 service as follows.

service gdm3 stop

If you are on a 64-bit Kali system, you may want to install the ia32-libs package in order to allow the NVIDIA installer to install the 32-bit libraries, although this is optional. If you choose not to do it, simply select no when the installer asks if you want to install the 32-bit libraries.

dpkg --add-architecture i386
apt-get update
apt-get install ia32-libs

Assuming you downloaded the NVIDIA driver to your /root/ directory, we need to give it executable permissions and run it.

chmod 755 NVIDIA-Linux-x86_64-310.44.run
./NVIDIA-Linux-x86_64-310.44.run

Once the installer finishes, you should reboot your machine. Once the system boots back up, you may see a NVIDIA splash screen, which will indicate that the drivers installed correctly, however, this is not always the case. In order to check if the drivers are working properly, execute the following command.

root@kali:~# glxinfo | grep -i "direct rendering"
direct rendering: Yes

Although utilizing the Cuda tools included in Kali is beyond the scope of this article, checking to make sure that they are working properly is always a good idea. The following command uses Oclhashcat-plus with some of the example files included in the package.

cd /usr/share/oclhashcat-plus/
./cudaHashcat-plus.bin -t 32 -a 7 example0.hash ?a?a?a?a example.dict

As you can see in the output above, the cards are recognized and the passwords are being recovered successfully.

How to Install Linux on the Zealz GK802: A Quad Core A9 ARM on a Stick

The Zealz GK802 looks a bit like a long, over-wide USB pen drive. Under a removable clip at one end of the stick is a male HDMI connector ready to be plugged directly into a monitor or large TV. On the other end of the stick are two USB ports: a micro USB to supply power to the GK802 and a female USB connector to let you attach peripherals like a keyboard, mouse or hub. Being a small, contained stick with an HDMI connector the obvious use for the GK802 is consuming video media.

Inside the GK802 is a quad core Freescale i.MX 6 CPU at 1.2Ghz sporting 1GB of RAM and a Vivante GC2000 GPU.

Inside the GK802 is a quad core Freescale i.MX 6 CPU at 1.2Ghz sporting 1GB of RAM and a Vivante GC2000 GPU. The GPU and video decoding acceleration of the GK802 are supported under Linux. Getting information to and from the GK802 is done over Wi-Fi and you can connect bluetooth devices to it in order to control the GK802.

Looking at the side of the GK802 you will see a microSD slot. A card clicks into place there contained well inside the GK802. If you remove the two screws near the HDMI plug you can slide the GK802 open, probably voiding your warranty in the process. Flipping over the GK802 you will see a second, internal microSD card which contains the Android image that came with your GK802. My unit came with an 8 GB Sandisk class 4 internal microSD card which contained Android 4.0.4.

How to Install Linux

In order to run a Linux distribution like Ubuntu, Debian, or Fedora on the GK802 you will likely have to open the hardware and change or modify the internal microSD card. If you want to do that you should only have to open it up once, permanently inserting a microSD card in the internal slot that instructs the device to boot from its externally accessible microSD card.

There are two parts to getting the boot to happen. First, install a customized uboot at a fixed location on the microSD card. Then setup a boot.scr file on the externally accessible microSD card telling uboot where to find the Linux kernal and start the ball rolling.

For testing I extracted the Xubuntu 12.04 root image and slightly modified the boot.cmd file to use 1080p as shown below. As you see in the example the boot.scr file is generated from the boot.cmd file using mkimage. Note that I was still booting off the internal microSD card slot. The dev/mmcblk0p1 line and the mmc and dev references in boot_normal need to change slightly if you are using this configuration on a card that will be inserted into the external microSD slot.

root@gk802:/# cat boot.cmd
setenv root '/dev/mmcblk0p1 rootwait'
setenv rootfstype 'ext4'
setenv kernel 'uImage'
setenv video 'mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24'
setenv extra ''
setenv boot_normal 'setenv bootargs console=${console} root=${root} rootfstype=${rootfstype} video=${video} ${extra};  mmc dev 0; ext2load mmc 0:1 0x10800000 /boot/uImage; bootm'
root@gk802:/# mkimage -A arm -O linux -T script -n "boot" -d boot.cmd boot.scr

Testing Video Playback

The GK802 out of the box looks like an overly wide USB pen drive.

Attempts to playback 720p video under Android 4.0.4 didn't work using XBMC. The same 720p files played back fine under Xubuntu using Totem. To stretch things on my Xubuntu install, I played the 1080p h264 version of Big Buck Bunny. I got a few stutters initially (around where the title of the movie appears) so copied the file to a local microSD card to retest. Playing from the microSD card, after one initial stutter I got clean playback, even during fast motion scenes. The GK802 was across the room from a D-Link DIR855 access point. Clearly network configuration, distances, and caching play a role when streaming 1080p content to a GK802 over Wi-Fi.

At idle with a 1080p desktop shown, the GK802 uses 3.1 watts. With 1 core at 100% power usage jumps to 3.8 watts. Compiling openssl using 4 cores power usage went up to 6.6 watts. OpenGL was a mixed bag, much of glmark2-es2 run in about 5.5 watts. The effect2d needed 7.6 watts. Toward the end of the OpenGL test I touched the GK802 and it was very hot to the touch.

Tune in next time for benchmarks on the GK802. A special thanks to Miniand for supplying the review hardware for this article. The Linux kernel for the GK802 is available on github. And the IRC channel #imx6-dongle on freenode. Documentation for the Freescale i.MX 6 is also available.

How to Replace the Unity Desktop on Ubuntu Using apt-get

It seems to be popular these days to vilify Ubuntu as a distro because of the recent change to the Unity desktop.  We are told the change was made for the purpose of re-creating Ubuntu in the form of a gadget-agnostic operating system, equally usable and familiar on a phone, a tablet, and a desktop.  Never mind that each of those digital devices was invented to serve a need that at the time was unfulfilled by the others, or that their screens are radically different in size.  They must look as though they are members of the same family.

To that degree, I'll gladly place myself firmly in the camp of the vilifiers.  I don't like the idea, I have no intention of making use of it, and I am certainly not convinced that it will bring hordes of new users to Linux.  But I am not one of those who claim that because of these changes Ubuntu is no longer a suitable distro for a Linux fan, that it is too commercial, that it does not have the flexibility a Linux distro should have.

Granted, I am certainly not one of the hard-core retired Unixers who think in C++ and regard a GUI as a crime against humanity.  Though I've been Windows-free and using various Linux distros for four years now, I still work more in GUI than CLI, and in my view the fundamental structure of Ubuntu is sound, adaptable, reasonably stable, and easy to shape into a form one likes.  You just have to dig down one layer below the Unity desktop to do it.

Install a Unity Alternative

That, of course, is almost embarrassingly easy, since relief from the oddly-structured constraints that Unity imposes on your work habits is only an apt-get install away.  Do you like an extra-light desktop?  Use 

apt-get install lubuntu-desktop 

Love wobbly windows and a transparent cube with all six faces in use?  

apt-get install kubuntu-desktop.  

Something between those extremes, just clean and powerful?  

apt-get install xubuntu-desktop.  

On your part, all you are required to do is twiddle your thumbs while the necessary packages are downloaded and installed, and when it's done you can log in to a very different experience than Unity offered you.  Furthermore, if what you installed on your computer was the full Ubuntu version, all the software it included is still accessible to you through your new desktop.  For example, in the modest, nearly bare-bones Lubuntu menu, click on Other: you will see a list of available programs and utilities that runs well beyond the height of your monitor. 

For that matter, if you are even more CLI-averse than I am you can get any of those desktops from the Software Center; it's just that the downloading and installing process from the Software Center runs as a deep, dark mystery, showing only a progress bar up in the corner of the screen.  The apt-get process remains fully visible on the terminal – what you see is what you get.

It's really a shame – there is so much more to Ubuntu than the Unity desktop would suggest.  It is, in its basic form, simply a variant of Debian, fitted out with a highly simplified installation scheme and privy to an extensive repository of programs and applications.  I just cannot understand the logic behind placing all those restrictions on the behavior of Ubuntu that the Unity desktop seems to require, when such rich variety is available otherwise.
