I've been trying to boot Kali Linux from my 8gb USB. I get to where I'm supposed to choose from one of the various options: Live, Persistent, Persistent With...... etc etc. I go on and select one, say the first: Live. However, Kali goes on and on forever whenever the text stops running up the screen and a mouse cursor appears on a blank screen. Nothing changes after this. It remains like this.

What could be the problem and how can I fix this. Thank you all in a dvance.

  • Can you post the whole output of ls -R inside the USB? – ncomputers Feb 7 '16 at 4:59
  • did you try disabling modesetting in the grub command line before you boot (edit command line and say if you have an nvidia gpu, add nouveau.modeset=0, don't know what you do for amd) – Cestarian Feb 7 '16 at 6:10

Two initial considerations are

  • You should use a USB3 device and port if possible as USB2 may be too slow
  • Make sure that the ISO that you used includes support for your graphics card or integrated graphics.

If you would like to try killing X and going to command prompt you could use Ctrl+Alt+F1 or Ctrl+Alt+F2 to switch to a command prompt and restart the login manager.

You can accomplish this by executing

sudo service lightdm stop && sudo startxfce4

or

sudo xkill -a && sudo startxfce4

If restarting the windowing environment does not work directly, and your hardware is supported, then there is likely something wrong with your Xorg configuration. Get to the command prompt again with Ctrl+Alt+F1.

End the X session again with

sudo service lightdm stop

or

sudo xkill -a

Backup your current configuration

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.old

Then have Xorg attempt to create a new config file and overwrite the current configuration

sudo X -configure && cp /etc/X11/xorg.conf.new /etc/X11/xorg.conf

Attempt to start XFCE again

sudo startxfce4

If the autoconfig does not work then post the old and new config file here. As well you should install the lspci command as follows.

sudo apt-get update && sudo apt-get install pciutils

Then please run lspci and post the output here. You can save the output as follows.

lspci > lspciOut

Then save it to any writable mounted device.
