[Archived - Unresolved] - Manjaro unable to login to desktop, Login boots be back to login window

[ArcticStag]

Hi There,

I have recently moved over to Manjaro from Fedora as I was looking for more control from my desktop. For this reason I have used the Manjaro Architect to complete the install. I have kept the home drive from my fedora install and have tried removing all of the config files that reference the desktop environment.

The issue that I am currently facing is that I am unable to login to the desktop environment every time I boot. I am able to SSH or TTY into the desktop and this works without issue. I have tried to follow the steps in both of the following issues;
manjaro forum article 21916
manjaro forum article 3904

The information here did not help me. I have found that I have been able to update everything and refreshed my pacman cache and still nothing.

Below is the information on my desktop environment
OS: Manjaro Linux x86_64 Kernel: 5.7.19-2-MANJARO Uptime: 16 mins Packages: 997 (pacman) Shell: zsh 5.8 Terminal: /dev/pts/0 CPU: AMD Ryzen 7 1800X (16) @ 3.600GHz GPU: NVIDIA GeForce GTX 1080 Ti Memory: 404MiB / 32103MiB

Any information that you need can be provided and

Hello and welcome,

@ArcticStag

Below is the information on my desktop environment

Is not quite clean looking, isn’t it? And quite generic information
Usually this is the kind of information we look for and the format to be provided be:

You mentioned architect install. Why not directly the preferred DE ISO ? That way you avoid most of the struggle or forgetting about some packages.
Each DE uses a default DM:
KDE PLasma > SDDM
Gnome > GDM
XFCE > LightDM

So, depending what DE you installed, the service corresponding to the DM can be checked if active or not. Example:
systemctl status sddm
Because i see zsh and you mentioned Fedora, i can assume you installed Gnome. That means:
systemctl status gdm

if you have done an update ,
you have to check with /etc/pam.d/*

see this

So just ran an LS on psm.d/ and this was the result

grep -E "pam_tally|pam_cracklib" /etc/pam.d/*

[ArcticStag]

Here is the result
grep -E "pam_tally|pam_cracklib" /etc/pam.d/*

/etc/pam.d/passwd:#password required pam_cracklib.so difok=2 minlen=8 dcredit=2 ocredit=2 retry=3

@ArcticStag

/etc/pam.d/passwd:#password required pam_cracklib.so difok=2 minlen=8 dcredit=2 ocredit=2 retry=3

I get the same output on my system, but I’m not having any login problems. Still, there were no .pacnew files in /etc/pam.d/ for myself, so if pam_cracklib.so is deprecated, then what must it be replaced by?

[papajoke]

cracklib is old! for a long time this line is commented since it is announced obsolete, It was before this update. Some rare people with old manjaro who don’t manage .pacnews may have it without “#”.

[ArcticStag]

So I wasn’t able to get this working so I gave up and installed Manjaro XFCE however I am seeing the same issue. I will archive this case and open a new case with the new information under the correct pages.
