Login Manager not found?

Hi Folks,

Suddenly I can't get X:

"Hey, you don't have SDDM, KDM, GDM or XDM. Can't use runlevel 4 without one of those installed"

I knew I have lighdm installed and worked fine. I check lighdm is installed

I installed XDM anyway and get XDM login manager but XFCE fails to start.

What could be wrong?

Thanks!

There are a few things you should try, if you didn't yet:

Did you upgrade the kernel recently? If so, do you use any proprietary graphics driver?
Do you see any errors (EE) in /var/log/Xorg.0.log?
Did you try to set runlevel to 3 in /etc/inittab then try to startx?

I forgot to mention this is a VBox client and kernel-firmware was removed.

1 yes, I upgraded to 5.15.80 but AFAIK there are no any proprietary graphics driver
2 yes, (EE) failed to load module fbdev but since this is a VM I don't think this is relevant
3 yes, I can startx from tty


Thanks!

If I remember correctly VBox uses its own graphics driver (I assume you have VBox extensions installed.) But since you can start XFCE with startx from tty, this is probably a DM issue. I'm afraid I can't help with that though, because I don't use any of those. The first thing I do after installing Salix is to switch to runlevel 3 permanently.

I can only guess, but you probably removed something that lightdm needs.

I have the same issue now on a native salix. I have all 3 lightdm installed: lightdm, lightdm-gtk and lightdm-gtk-settingsVM
On the VM reinstalling lightdm-* seemed to fix the issue. I did the same on the native salix and no success.
