A few days my free space was like 130 gig left, yesterday it was ~100 GB. Now that I rebooted it is 70 GB. What is going on? I haven’t been downloading any very large files at all. In fact I have deleting old large large files
How do I check to see what my free space left actually is?
Rebooted and now Thunar reported 133.5 GB free space. Is there a bug with Manjaro is dealing with disk space used? Something wrong with my SSD?
Which folder are you checking for free space?
I had the same after install Manjaro, when i asked the same of you one here had immediately suspected it was just Timeshift making back-up in the background periodicly and he was right, it was timeshift.
I don’t have a Backup device selected for this.
I’m not saying that this is it but…
keep an eye on the hidden file “.xsession-errors”, in my case as I never turn off the pc (always in suspension), this file came to have in my case 89GB (kaffeine was responsible for it and I was to blame for forgetting to turn it off when entering suspension mode.) A simple shutdown returns in some cases to normal, in others it will create a “.xsession-errors.old” with those gb. (variables).
If this is your case, although I am not advising you to do this (actually, this solution can be found in forums) and as long as you are not interested in the useful information in the “.xsession-errors”, you can create a script with the content:
#!/bin/bash
rm ~/.xsession-errors
ln -s /dev/null $HOME/.xsession-errors
example:
to view the space in graphic mode: baobab
Thanks. This wouldn’t occur to me to check for this. I don’t see any proper use for this if it is going to consume that much disk space.
as @maycne.sonahoz asked:
I’d suggest you check the whole device/filesystem.
Or you open a terminal and issue:
df -h
and don’t rely on thunar to tell you
With the ext4 filesystem, there is also a “reserved” amount of space, only accessible to the “root” user - which is 5% of the whole available space by default.
… which is (can be) quite a large amount with hundreds of gigabytes or even terabytes of storage capacity
you can adjust that with:
tune2fs -m _percentage_
to be just 1% … or so
see:
man tune2fs
I would not advise to set it to “0” (zero)
because then even the “root” user has no margin in case the filesystem gets full
It is indeed unlikely that this (or any) log file has grown that much
but that doesn’t mean that this (or any other) log file has no “proper use(case)” 
Even so I went nuts trying to free up some Storage on the Linux SSD. Deleting large Porn videos I have no idea why I D/L them. To starting Steam w/o mounting the Ext HDD to check installed game to /home/user/…
Maybe I just need to reboot/turn off the Computer more often?
Your reply doesn’t make much sense to me - and is without substance.
(you might want to keep in mind that you are the one sitting at your machine,
everyone else here must rely on as much or little detail you share of what you can see, for advice …)
I’ll not ponder whether porn is worth keeping …
ssd’s need special treatment - usually it’s automated
look into “trim” …
I have zero experience with ssd’s - because I only read about them - I do not own or have used one to this day.
That is not likely to be beneficial - I do not see how it could be.
Nevermind about the porn. I also have DVDs(Mine) Transcoded to MP4 files. I keep Linux Games on my Ext HDD to preserve Storage Space.
But I was surprised that the .xsession-errors was eating up my SSD.
You still don’t use an SSD? They are well worth it due to major increase in performance, less noise, and heat.
… well …
did it really?
as far as I can see from all that is here, there is no evidence for that
It was just a suggestion - a possibility - what might have been the cause …
My spinning hdd is working just fine in a laptop with an Intel i5 from around 2015 or so - probably even older
Sony Vajo SVE14
Why replace it when it works just fine? …
.xsession-error.old taking up space?
you need to use a few more words
to make your response resemble a useful answer …
I don’t know what to make of that your response.
I can guess - but that guess might as well be wrong.
Well, you might want to check what errors are logged in there, and fix the issue at its source…
You don’t need to replace the Laptop, merely replace the HDD with an SSD.
What do you advise?
no, I don’t need to replace anything
it works just fine - thank you very much - without having to spend effort or money
It works just as intended.
I do not have any problems.
You seem to be the one to be experiencing them
regarding what?
… what is you actual issue - what doesn’t work - what needs to be addressed/fixed? …
You were already given a good suggestion for how to find relevant data
