Failed to start light display manager

[Pranav S M]

I found 'failed to start light display manager' problem after boot to kali Linux from Windows 7.

[HillSonMX]

uname -a
Linux kali 5.16


I just did normal update process with

sudo apt update && sudo apt upgrade -y && sudo apt dist-upgrade && sudo apt autoremove -y && sudo apt autoclean


now

uname -a
Linux kali 5.17


and can not start normally ( black screen just after kali logo ) but still I can go to TTY (ctl+alt+(F1..F3)
I check some log file, and you can see tell is something wrong with lightdm and tty process and finally Xorg log point me to a solution.



/home/<user>/.local/share/xorg/Xorg.0.log


4947494849494950











then cheking other forum find a solution could be forcing X to use fbdev driver and provinding the framebuffer device ID by:


Create the .conf file:



/etc/X11/xorg.conf.d/fbdev.conf


Edit it:




Section "Device"
Identifier "Card0"
Driver "fbdev"
BusID "PCI:0:8:0"
EndSection



Please mind that your BusID might be different.


You can check it with: (if exist)



cat /root/xorg.conf.new


or you can just run




Xorg -configure



which will create /root/xorg.conf.new. Then look in this file for your BusID and act accordingly if it differs
