Manjaro-Arm boots but goes into black screen

lightdm
raspberrypi
#1

Using a Raspberry Pi 3 and up until recently everything had went well, now the system boots but there’s no login screen, just a black void.

Opened a TTY and checked for errors relating to “lightdm” and the service seems to be running ok, so it’s strange why there isn’t a login screen and all.
Got the latest updates on my system too.

Any ideas on how to fix the issue would be appreciated. Thanks!

[ARM Update] Don't update systemd to 240 if you use LightDM
#2

Please try posting dmesg, journalctl -b, and most importantly /var/xorg/xorg.0.log

#3

Not sure how I can do that without being able to use a browser.
I could probably copy those files and post them here.

#4

No official version is using Lightdm.
WHat edition did you download?

#5

Running uname -a returns this:

Linux manjaro-arm 4.14.86-1-MANJARO-ARM #1 SMP Fri Dec 7 20:39:40 CET 2018 armv7l GNU/Linux

Have the Mate desktop installed. Previous versions of Manjaro came with it by default.

#6

That’s a very old install then. Like from 18.05. :stuck_out_tongue:

#7

Update: Was able to fix my login issue due to problems with systemd.
The logs showed systemd-logind failing to start the display manager in this case, and downgrading to an older version of systemd (239) did the trick.

Another user also reported the issue here:
https://bbs.archlinux.org/viewtopic.php?id=243385

So for now I’m running an older version of systemd until the problem gets resolved.

#8

Awesome. Thanks for the report. Will do some testing on my own too.

#9

Did some testing. I did not have the same issue as you.
You sure you are all up to date?

#10

Yup, as far as I can tell all the updates are good.

Could be that my install was out dated and all, so that may have broken a few things.
But other users have reported issues with systemd 240, so let’s see how they manage to fix it.

#11

@Strit UPDATE: As per previous entries, had to downgrade systemd to be able to use my system again, however…
when the updates rolled again Manjaro tried to update systemd again, so I added it to the “ignore” packages section in pacman.

Question is: would that be safe? I mean, don’t want to have “partial” updates and all.
Or, should I update with “pacman -Syyuu” to ensure packages in repo/local stay synced?

EDIT: It is as I feared: the same issue happens also to the Arm version of Manjaro.

I’m guessing the work around it’s the same?

#12

Not sure. I just released the new kernel tonight, but it is mostly identical to Arch Linux ARM’s. Systemd is Arch’s directly.
I think you have to update systemd to get that working again. Or downgrade libidn2 (not recommended, might break other stuff).

#13

The system is broke after the latest attempt to update it.
Best to re-install and start fresh off with a new build.

Question: got a new Pi3 B+; will the image work for the new hardware?

#14

I would suggest you use the rpi3 image. :slight_smile:

#15

Same here.

Sometimes screen turns right into black, after boot messages part is passed, at the time
the GUI should be opening up.

I did play around with some HDMI/DVI settings, a potential source of it. Didn’t have that much success.
