Brevity is something we don’t need. Please post entire outputs when asked. In this case the inxi command filters out any personally idetifiable information, if that concerns you, so there is no reason not to post the entire output. So please, post it all and not just what you think will be needed.
As it stands, what you have given us doesn’t tell us much more than your kernel and that you’re using KDE. Try again.
The same applies to the journal output. Cheers.
I corrected this mistake and added in my previous post all the information from the output
Note 1: You have no swap space defined. You should probably attend to that sooner rather than later.
For consideration:
The easiest for you would likely be to completely reinstall Manjaro (from scratch). You would need the latest available Manjaro Installer ISO. Use the latest ISO, and not the one you already have, as important changes have been made since that ISO was released.
You would need a way to save any data you wish to keep. This would be easy if your /home was on a separate partition. If it isn’t, you would need to boot with a Live Installer, and manually copy important files to a USB drive, for example. If you have nothing that you absolutely must keep, then that makes the process a little easier.
As you can’t boot currently, you would naturally need to use another computer to download the ISO and burn it to DVD, or prepare either a new USB installer or Ventoy USB (recommended). Perhaps you can use the computer of a friend or family member to do this.
I believe this might be the fastest way to get you back to a working system. Please let us know if there is any insurmountable reason why this would not be an option for you.
Cheers.
Just for the record, with 16 GiB of RAM or more, you don’t really need swap. I’ve been running Manjaro Plasma in 16 GiB of RAM without swap for well over four years now, and I’ve never run into any problems.
Depends.
Certain games.
Or even browsing habits could tip it.
And to say nothing of compiling and such … to compile firefox on a 16gb memory machine I needed 32gb of swap. 
(well OK it also had some fancy emulate to profiling for optimized build in there but still)
Well, okay, I am not going to claim that not having swap will work under all circumstances, but for normal everyday usage, there shouldn’t be any need for it. 
I swear there was the odd occurrence where something (gnome? extension? software?) explicitly expected SWAP, regardless of if there was 8 or 32gb of real RAM. But I dont have any data to link to so it may be a mythic tale. 
Hmm… At the risk of wrongfully suggesting that you might be misremembering things, are you not thinking of the change in systemd that causes it to now automatically detect and activate all swap partitions it finds unless they are explicitly listed and commented out in /etc/fstab? Because that is something I did run into over here.
I had created a swap partition on my internal HDD — it’s an old but so far still fully functional “spinning rust” drive which I only use for storing backups — but I had never added it to /etc/fstab, and the change to systemd of a while ago caused that swap partition to become active. So I had to explicitly add it to /etc/fstab as a commented-out line.
It was more along the lines of software malfunctioning because of lack of swap.
It could have been something a bit more complicated … like calamares functioning on live ISOs.
If the live system is loaded into RAM, depending on the physical memory present, there may be too little available for calamares to do its thing and install.
(I remedy this on my ISOs so that zram is used, which means the installer runs well even on low memory systems)
I really dont recall though.
The following table shows default/recommended swap sizes when performing a Manjaro install using the Erase Disk partitioning method.
| Preference | Size | Description |
|---|---|---|
| No Swap | 0 |
If no Swap is defined, and later you need it, a Swap partition or file must be manually configured. It is recommended to configure Swap now; during installation. |
| Swap (No Hibernate) | 8.80 GiB |
Default swap partition size is approximately half the amount of your system RAM if ‘No Hibernate’ is selected. |
| Swap (With Hibernate) | 17.18 GiB |
Default swap partition size is approximately equal to the amount of your system RAM if ‘With Hibernate’ is selected. |
| Swap to file | dynamic |
Swap file will be created under / (root) by default. |
These defaults are determined internally by Calamares depending on the swap preference selected. These figures are based on a system with 16GB of physical RAM. However, we can safely extrapolate that swap space equal to the amount of RAM is pre-selected when hibernation is desired, and half that amount, when it is not.
These are sane defaults, in my opinion.
It’s not really a question of how much swap we think we need, but moreover a what if scenario; for example:
What if I have 16GB RAM and an 11GB ISO file in RAM when the system hibernates; or worse, shuts down unexpectedly? What if I don’t have enough swap defined to safely store the amount of data in RAM?
Of course this is less of an issue for someone who maintains a constant vigil for this kind of circumstance; if such a person exists; or if one simply has hibernation disabled - in which case, half the amount of RAM is likely a fair tradeoff.
Last time I saw the SWAPs that calamares was creating … it was always zswap swapfile and it was always 512mb.
This is almost certainly a bug, but I dont know if its been fixed or what.
But I will also note that in the last message above I was describing the functionality of calamares on a live system running with no swap configured (or whatever is the default for live systems, maybe 512?).
Examples as recent as the last few months;
Using the Erase Disk method swap is selectable with the defaults mentioned, but not so across all partitioning methods. When choosing Install alongside or Replace a Partition, I’m uncertain that swap is created at all.
Edit:- 512MB seems consistent; at least, that’s what I seem to recall. It’s the minimum, isn’t it? Or, rather, the minimum amount of free space that needs to be available before a zswap file can be created… though, I can’t find anything to back that up in my 2 minute search.
Again, using Erase Disk, the Swap to file option is available, but of course there’s no indication of size (being dynamic).
I thought carefully about this, and realized that in my case a complete reinstallation is suitable. My work project critical files was are saved.
But I need to retrieve saved bookmarks from browsers, and it is also important to retrieve open tabs from browsers. I really need them for my study, work and life interests activities. These are the rest things I cared about that broken system.
Here is a list of browsers that were installed: firefox, opera, chrome, chromium, brave and iron-linux.
I’ll start to search for how to do this.
And would be grateful, if you may could to suggest keywords for searching on this case, to direct to a place where might the solutions be.
Fortunately, these browsers should have their own method to save bookmarks.
In Firefox (and Firefox-based) browsers, you can go to: Bookmarks → Manage Bookmarks → Import and Backup (tab): here you will see both Import and Backup as two separate options, which should be self-explanatory. Your bookmarks will be exported as a .json file (name it according to the browser it came from) which can be imported to a newly installed Firefox later.
If you use Firefox Sync, then your addons, open tabs, etc, should be maintained through that (which will also keep your bookmarks). If you don’t use Firefox Sync, I have nothing to suggest, apart from physically zipping and restoring your profile directories (which could get messy).
Vivaldi also has a Sync feature.
It’s likely easiest for you to setup Sync on each browser you use; at least, those that support it. This is usually done through the browser, or by setting up an account on the Browser’s home page.
This is not a Manjaro issue, nonetheless, I hope this information was helpful.
Cheers.
some profiles are stored in ~/.config
like google-chrome and chromium and other chrome based browsers
look for that name in those directories
opera I don’t remember - it’s either it’s own dedicated directory under ~/
or also in ~/.config
list the contents and the name will stand out
Firefox and derivatives store their profiles in ~/.mozilla and similar names, likely named after the browser
