Boot or login broken after 'pacman -Rc' and update

[cscs]

@DireDeer

pacman -R -c

This command is not the normal way to remove things and should be used with care as ‘cascade’ can include packages you did not intend to remove.

We can maybe look in the logs to see what was done;

grep -i removed /var/log/pacman.log

@DireDeer

flooded me with questions of “Replace with /extra/5?”

Sounds like the replacement of many kde packages with the -5 suffix due to the upcoming KDE 6.

[HowTo] Resolve an unbootable Manjaro (black screen, login failed, cant boot, etc)

When we have problems gaining access to our systems it is difficult to gather information, let alone fix any problems. Here we will cover common causes and solutions to ‘manjaro wont boot’. TTY If your desktop does not load properly then you might still be able to use most, if not all, functionality by dropping to a non-graphical TTY. By default your system will have multiple TTYs, with each corresponding to an Fx key. Your desktop is assigned to one as well - most often F1. You can chang…

Once there we probably would like some of those outputs.
Maybe also inxi -Fazy

Oh, and if you need a way to paste the outputs see this:

[HowTo] use public command-line pastebin services without installing anything!

Sometimes we might want to easily share terminal output. While this can be accomplished directly in the forums or manually through websites like pastebin, there also exist a number of open services that allow you to paste and share directly from the command line by using tools you already have installed. This is great for many situations, including troubleshooting from a non-graphical boot, or simply very large outputs. Here I will share a few examples and how to use them. Services and Exampl…
