I still don’t know what the issue might be … I built a local Manjaro Cinnamon ISO using linux70 (stable) - which will not load the desktop upon boot - prompt for password instead of autologin.
- ThinkPad x13 AMD Ryzen 7 Pro w/ Radeon 780 Graphics
The pacman.log list the gpu packages installed - nothing intimidating there.
I am not good at interpreting the logs - looking into /var/log/lightdm
The seat0-greeter.log shows a message about an error spawning a command line
dbus-launch --autolaunch .... bla
I am having a lot thoughts
- pam
- systemd
- could be interaction between kernel, pam and systemd
But I cannot make head or tails … nothing useful I’m afraid
I am going to test a similar ISO but with linux618
EDIT:
Using a process of elimination - throwing something at the ceiling to see if it stick…
After building a linux618(stable) ISO I can boot the same ThinkPad with no issues.
The LIVE desktop open as expected.
As I can reproduce your issue in it’s full using linux70, I am guessing that we are looking at the interaction between the kernel, pam and system - which one is
I don’t know what it is - I am utterly clueless… sorry…
I have now switched to another test laptop
- ThinkPad T495 with AMD Ryzen 5 PRO w/ Radeon Vega Mobile Gfx
There is no issue booting the linux618 ISO - straight to desktop.
Restarting the second laptop - this time booting the linux70 ISO - no issues - straight to desktop.
Retesting the x13 - same mysterious issue using linux70.
EDIT:
Next step - new ISO using linux71(unstable) - no issues booting on ThinkPad x13 and the same goes for ThinkPad T495.
$ uname -r
7.1.1-3-MANJARO
I cannot be conclusive but it do point to the aforementioned interaction between kernel, systemd and pam security or a kernel regression or it could be something entirely different.

I wanted to make a note of this yesterday but forgot.
With the aforementioned ThinkPad x13 which exhibit the strange live boot issue using linux70 a little twist can be added.
The system is my primary working laptop - it was only booted with the ISO for the test.
The twist is, when normally the laptop uses linux70 so there is no reason why booting an ISO with Cinnamon and Linux 7.0 should fail - it simply makes no sense - no sense at all…
