[SOLVED] LightDM sometimes starts, sometimes not.

Hello Arch Users,

I am after fresh Arch Linux setup with Xfce + LightDM on Ryzen 2400G build. System is working well, but i have got some problems, that keep me away from being happy Arch Linux user:

- on system start there are ACPI errors, my MOBO is MSI X370 Sli Plus bought with updated BIOS.
- LightDM should start after some basic system servises, but it sometimes doesn't start and there is only black screen with nothing. Ctrl, Alt and F1 don't work.
- turning off system sometimes work, sometimes not - there is black screen, but computer is still working.
- sometimes I have got system freeze, usually about after 2 hours of system working (sometimes freeze is happening while system starting in cli).

Please help.

Welcome to the forum, please refrain from shopping-list threads, one thread per issue is mandatory.

The ACPI errors are "normal", they indicate that the ACPI implementation of your BIOS is broken what is "normal" (and sad)
You might run into https://wiki.archlinux.org/index.php/Li … TTY_output

As for the two remainders, look at your journal and open new threads for them.

Thank You for your answer. Next time I will post new topic for each issue.

It seems that setting up LightDM to wait for graphic drivers and updating kernel helped me with freezes. I haven't got any since yesterday.

I also solved ACPI errors by adding GRUB_CMDLINE_LINUX_DEFAULT="acpi=off" in /etc/default/grub. But I am not sure how it affects to my system.

However, I still have got a problem with shutdown. My machine doesn't fully stop each time.

Nope, you pretty much broke your system this way and can now fully expect things like poweroff, reboot or suspend to fail.
Undo this.

Please mark this thread as solved (edit your first post and alter the subject) and start a new thread w/ the subject reflecting the pending problem.
