Leap 16.0 clean install boots to command line

[Inigo]

Novice Linux user, but did install Leap 15.6 with Xfce on a Beeline Mini S13 N150, and it was working fine.
Did a clean install of Leap 16.0 over it and the machine booted to command line.
tried:
systemctl start display-manager
response (in red):
Failed to start display-manager.service: Unit display-manger.service not found
What command(s) do I need to run to troubleshoot/get the system to boot to GUI?
I have been unsuccessfully searching, so any help is appreciated.

Try:

systemctl status display-manager.service

It should output 20+ lines. If error instead, try:

sudo zypper in lightdm

and see what happens with a reboot. If still no X:

# zypsei x11 | wc -l
20

If the result is much less, then X11 may have failed to install, and wayland support failed too. Is patterns-base-x11 installed?

journalctl -b | grep aile may produce failure clues.

Thanks!
sudo zipper in lightdm installed 89 packages, so definite progress but still
[FAILED] Failed to start X Display Manager
tried # zypsei x11 | wc -l but nothing happened
how do I check if patterns-base-x11 is installed?

[mrmazda]

zypsei x11 | wc -l was a mistake, as zypsei is a script I use:

# cat /usr/local/bin/zypse
#!/bin/bash
echo "# zypper --no-refresh se -s $* | grep -v '32bit|debug|devel|srcp|openSUSE-20' | egrep 'x86|noarch'| sort -f"
zypper --no-refresh se -s $* | egrep -v '32bit|debug|devel|srcp|openSUSE-20' | egrep 'x86|noarch'| sort -f
#

Use zypper se -si <string> or rpm -qa | grep <string> to search for packages already installed. You could skip the searching and just zypper in patterns-base-x11 patterns-xfce-xfce, and if already installed, zypper will say so, otherwise install.

zypsei

This command does not exist.

@Inigo

how do I check if patterns-base-x11 is installed?

rpm -q patterns-base-x11

And please do use preformatted text when posting computer output.

Thanks mrmazda and arvidjaar! I clearly had a bad install as

zipper in patterns-base-x11 pattens-xfce-xfce

installed 739 packages, it now boots to GUI, and I now know how to format the computer output text for this forum
