I was looking to try a new Display Manager to add some flare on the screen before I log in to my system.
The Desktop Environment and Display Manager I’ve been using has been Gnome and gdm.
I wanted to try LightDM.
I installed it through pacman and changed the Display Manager through the EndeavourOS Welcome app.
When I reboot, my system is stuck on the screen that says
:: running early hook [udev]
Starting systemd-udevd version 253.4-1-arch
I have tried booting into tty through grub or using ctrl + alt + F2, however the screen is still stuck at the same message.
So you can give terminal commands in TTY?
If not, then you can
arch-chroot into your system using the USB installer.
arch-chroot in our wiki for more details.
Then you can change to the previous DM with commands:
sudo systemctl disable lightdm
sudo systemctl enable gdm
and reboot back to the system.
I had trouble entering any commands into the TTY, but using
arch-chroot did the trick.
What advice do you have on diagnosing why my system doesn’t like booting into lightdm?
You can look at some logs, like
less /var/log/Xorg.0.log # or older
sudo journalctl -b -0
For the latter, see also the manual page
for more options.
Also logs in folder
/var/log/lightdm can be useful.
Besides lightdm, did you also install either lightdm-gtk-greeter or lightdm-slick-greeter?
You might want to take a look here:
Hmm I did not, I would guess that either of those might be dependencies that LightDM needs?
Yes, LightDM is just the base, and supports multiple greeters that are layered on top.
lightdm-gtk-greeter was the most stable when I was playing with Display Managers for ARM.
lightdm-slick-greeter either works or it doesn’t depending on the Desktop Envirornment. Slick’s advantage is most people think the esthetics are prettier than gtk-greeter.
Plus, once lightdm is installed, it must be enabled via systemctl. just the opposite from @mauel 's post.
sudo systemctl disable gdm
sudo systemctl enable lightdm
I would highly suggest reading through the above link before trying again.
Especially if you try slick-greeter. That requires configuration in /etc/lightdm/lightdm.conf
Only one greeter can be installed at a time.
It doesn’t look so, checking their pacman info.
Why did you think so?
You are correct, brain deterioration at my age is unavoidable.
Again, you are correct. I referred back to my Topic about lightdm-slick. You can have more than one installed, but then you have to specify which one is active in /etc/lightdm/lightdm.conf
