Views: 67644 Description: After your fresh install of kali, you might run into some problems.
One of them consists of the login screen missing and returning:
"Oh no! Something has gone wrong.
A problem has occured and the system can't recover. Please contact a system administrator"
To fix this issue (a temporary fix), press CTRL+ALT+F1, it will take you to the terminal. From there, check if you can use the command "startx"
If you get the following error:
-bash: startx: command not found
The problem would be that you don't have the x window system functioning yet, install it by using the command:
apt-get install x-window-system
Let it install and from there, you should be able to access your graphical user interface using "startx"
Don't forget to make sure that all your packages are up to date.
This is step by step how to fixs or resolves problem Kali GNU/Linux 1.0.7 kali tty1 caused by lost or removed GNOME Desktop Environment
# apt-get update # apt-get install xorg # startx
Note: The steps above need internet connection, so you need to connect your pc to wifi or LAN. Here iam use wifi connection.
To connect wifi, follow below instructions :
Okay, I'm going to try and answer your question, even though there is no terminal output included in your question.
The command ifconfig wlan0 does not turn on your wireless card. It gives you information about your wlan0. To turn on your wireless card, you would enter ifconfig wlan0 up. Although, it's not always wlan0. To find out the name of your wireless card, type iwconfig, and look at the row that has some information in it, not 'no wireless extensions'.
To be able to run the commands ifconfig wlan0 up, iwconfig wlan0 essid name key password and dhclient wlan0, you need to be root. So, you have to put the word sudo before those commands (unless you're already logged in as root).
The password in the command iwconfig wlan0 essid name key password should be in hexadecimal. If you want to type the ASCII password, you would use iwconfig wlan0 essid name key s:password.
The command iwconfig wlan0 essid name key password only works with access points that use WEP as encryption. If the access point uses WPA/WPA2, you'll have to use another method to connect, found here: How do I connect to a WPA wifi network using the command line?
Also, might I ask, is there a reason why you're trying to connect to a WiFi network through command line? Unless you're experimenting of course. Source: http://askubuntu.com/questions/294257/connect-to-wifi-network-through-ubuntu-terminal
After you follows step by step above intructions, i am pretty sure that you has login linux in GUI. The last one is you open terminal and type this command
# apt-get install gnome-core kali-defaults kali-root-login desktop-base
Now your linux boot normally and the problem fixed.
