Hi!
I'm using AntiX 19.5 Core which is debian based distro without GUI in Virtual Box. You just get tty at startup in core version of AntiX Linux

System
Code: 
Host: antix1
Kernal: 4.9.0-294-antix.1-amd64-smp
Arch: x86_64
Bits: 64
console: tty1
Distro: antix-19.5_x64-core Wobblies 24 January, 2022

I installed xserver including xfce, lightdm and xinit using
Bash: 
apt install xserver-xorg x11-xserver-utils xfonts-base x11-utils lightdm lightdm-gtk-greeter xfce4 xfce4-goodies xinit -y

After restart lightdm started, I logged in as normal user without root and without any problem and everything was working perfectly.
But didn't wanted to use any Login Manager as I prefer to run startx whenever I wanted to use xfce. So I removed lightdm and lightdm-gtk-greeter using apt remove.

But after reboot nothing was working when I enter startx. I was getting errors
But if i run startx as root then it works perfectly. Then I guess these errors have something to do with permissions which lightdm was doing automatically

Is this a systemd distro?

Try this as root

systemctl set-default graphical.target


I have to admit, I find it a little ironic,you are trying to run X in a distro called "anti"X! :)
 
Can't help with the virtual box, but to start your sysVinit system in text mode, the usual way is to place a 3 in the initdefault line in /etc/inittab:
Code: 
id:3:initdefault:
and reboot. Check the notes in the file.

The segmentation fault in the xorg log file is an ominous indicator. It may mean some code is accessing memory it shouldn't.

Thanks for your reply
That didn't worked
in file there was 5. I replaced it with 3. After reboot gives me same error after execution of startx.
I cannot understand. Why it was working with lightdm but not with startx(xinit)
 
what is it with virtual box about which you can't help?
Click to expand...
Of course if I could help, I would, but unfortunately I have so little experience with virtual box itself that I am of no real use there.

I replaced it with 3. After reboot gives me same error after execution of startx.
Click to expand...
I gather from this statement that the virtual computer did boot to runlevel 3, and showed a text prompt, at which you ran "startx" which failed to bring up X.

I see two problems, the segmentation fault and:
cannot open /dev/tty0 (Permission denied)
Click to expand...

I cannot say whether or not they are interacting with each other.

I'd try the permission issue first.
Here are the default permissions which work on my debian system for tty0
Code: 
[big@small ~]$ ll /dev/tty0
crw--w---- 1 root tty 4, 0 Jun 28 08:09 /dev/tty0
You should have something at least as permissive as that. X should by default have permission to write to the tty.

To check out whether X will actually run, I would create a file: .xinitrc in my home directory with the contents:
Code: 
exec xterm
If you don't have xterm on your system, replace "xterm" with any other terminal.

Then I would boot to text prompt and run the following command:
Code: 
xinit /home/<username>/.xinitrc -- /usr/bin/X :0 vt1
where you insert your username for <username>.

This command instructs X to run, check out the .xinitrc file and start whatever is in there, which in this case is the terminal, xterm, and start it on the first virtual terminal.

If X runs and there's an xterm on screen, you can start up a window manager like openbox or a desktop environment from that xterm with some relevant command. If X fails, then there's a deeper problem I think.

It is not working. But with $ sudo xinit /home/<username>/.xinitrc -- /usr/bin/X :0 vt1 it opened xterm
Even xfce is working fine with root user
 
parse_vt_settings: Cannot Open /dev/tty0 is usually caused by no permissions

add user to input, video and tty groups
chown user:users /dev/tty0

I ran
Code:

sudo useradd -g video user
sudo useradd -g input user

That didn't worked but now error is changed
Code: 
Fatal server error:
(EE) xf86OpenConsole: Cannot open virtual console 7 (Permission denied)

I guess i have progressed lol!

After running
Code: 
sudo chown user:users /dev/tty7
I think it got even worse
Now this is the error
Code:

As others said, antiX use SysV, and for the login session it uses elogind, while systemd uses logind. https://github.com/antiX-Linux/elogind-antix/blob/master/README
Since you're using the core version, I suggest you check whether it is installed, and if it's not, install it and try again. Tho, I would recommend that you create a new VM and start over, to get everything in place. Also, it's always a good idea to create a snapshot and work on that, instead of the main image, that way, should anything go wrong, you can just delete the snapshot and start again without having to recreate the VM. :)

I have tried many times but not working. I'm ending up on segmentation fault again and again

Have you tried asking at antiX forum?
antiX's creator himself, anticapitalista, answers questions there, so with a bit a luck he might have the answer you're looking for. :)

Well! I tried to login there but they have some issues with their website. I'm unable to create an account.
But I will try on MX Linux forum

lol! Now their forum is working fine
I will ask for help there

After banging my head at google many times I finally found the solution

Code: 
apt install xserver-xorg-legacy
I does not really know why installing xserver-xorg-legacy works but now startx is working without any Login Manager and root user.

Can anyone please tell me why it is working now? What it has to do with segmentation fault and permissions?

Probably your VM was "emulating" a legacy/exotic video driver. "xserver-xorg-legacy" essentially lets you run whichever tty you're gonna run X on as if root was running it (setuid). This is different than simply running as root, a'la su -c, sudo, or doas (did I miss one, lol) from a security POV. Explaining it really in lay terms would be saying: instead of you acting as the boss, you're asking Ursula in accounts to do something and she is treating you as if you were the boss... That explanation was garbage. You'd be better off letting Google explain setuid...

Anyway, the "driver" is probably only designed for single user mode. The segfault is caused by this somewhere along the pipeline.

After installing xfce4 just run:

This is a pretty old thread. Odds are good that OP has moved on and/or resolved the issue (one way or another).
