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

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
