I have a very odd problem that happened to me twice since I clean installed Kali Linux V2.0 a month ago. Both times I handled the problem by clean installing the OS again. I looked it up online for hours but couldn't find any solution for the problem or any issue similar to what I had.

What I experienced was a freezing at the login page.

This occurred after I shutdown the system with the power button. The shutdown procedure was stuck for some reason and eating my CPU (according to the fan speed and heat).

I reopened the laptop and booted into Linux, but this time all the data that was being displayed on the screen while booting was in a different font size. After that I got to the login page again, with a different resolution, the system froze, I couldn't move the mouse, use the keyboard etc.

Again ... CPU was working hard according to noise of the fan.

I also tried to get a shell command using the ctr+alt+f2 but no luck..

I haven't installed any custom driver or any program the can cause the problem. I'm using Sony Vaio z45gd laptop

Kernal : 4.0.0-kali1-686-pae
CPU: Intel® Core™2 Duo CPU P9700 @ 2.80GHz × 2

  • Next time this occurs, use some of these codes to investigate what is happening, en.wikipedia.org/wiki/Magic_SysRq_key May 29 '17 at 19:55
  • When you powered off the system with the power button, what was running on it? I doubt that your system might be running a system upgrade. And force shutting it down causes these kind of issues. I have experienced similar kind of issues with a Linux Mint system in the past.

i am just assuming you get graphical error, as i froze last time that i used nvidia graphic.

did you configure your graphic to be such nvidia, or others? in driver manager before this error?

but first thing, to go go the terminal while in the black screen try to use ctrl+alt+ f1-f6, just try all of them until you get into one of them, cause you onyly posted using ctrl+alt+f2 which it didnt work. So try again and see what happens.

secondly, try to remove your graphical diplay by using , for example sudo apt-get purge nvidia*. -> nvidia* means purging all of the nvidia components. then reinstall then using, for example sudo apt-get install nvidia-current-updates.

finally restart your PC.

point to be noted, sometimes when you are in the terminal, you are not automatically connected to the internet, using nmcli d wifi connect [name of your SSID] password [your password] wlan0 .

  • @Kaldy Imanie Thanks a lot for your replay , I hadn't done anything or install anything last time it happened, just used to serf to web You-tube and compile basic C programs ... I will try all of your steps next time it will happened, but i why should i install Nvidia graphics components if i don't have Nvidia graphic card? Sep 12 '15 at 23:33

You can try following, This worked for me: 1. When at login screen, Press Alt+Ctr+F3. You will land on terminal window. 2. Enter your credentials. 3. Since your apt-get update && apt-get upgrade was inturrupted, please try following command: "dpkg --configure -a". This will resume your installation. 4. Let it complete, reboot the system. 5. You will be in upgraded Kali linux.


So here is what I've done to fix the problem:

  • Booted Kali in recovery mode
  • Logged into the root account by typing the password when prompted
  • nano /etc/gdm3/daemon.conf
  • Uncommented the automatic loginenable = true and the automatic login = root
  • Ctrl+O (saved) and Ctrl+X (exit)
  • Ctrl+D (exit terminal)

I let the recovery finish and I got the desktop back.

Note: You might fix the problem just by entering recovery mode.
