Hi, I have multiple questions:
my headphones losts connections itself. i have to turn off and on my headphone to connect again.
Does needed system clean up from temp cache unwanted files as it happens on Windows OS? In windows i was using cleanmgr tool. here how happens? if needed which terminal commands?
Thanks in advanced.
Can you please provide inxi -Fza?
If you have an Intel AX200 for bluetooth, you’ll have to downgrade the linux-firmware package, which I can help with. There is regression issues in newer versions.
I can only answer this question here-above ─ I do not have any experience with Bluetooth devices.
The short answer is “no”. The longer answer is that temporary files are stored in /tmp, which is by default a tmpfs in Manjaro. tmpfs is a special type of filesystem in Linux-based operating systems, and it lives in virtual memory, i.e. it starts in RAM, but the contents can be swapped out if needed ─ or at least, if you do have a swap partition or swap file.
What this means is that the contents of /tmp are always deleted when the machine is powered off (because they do not exist on your drive), and in addition to that, by default, Manjaro also runs a script that periodically deletes the contents of /tmp that are no longer needed by any process.
There are of course also certain caches ─ both system-wide and in your home directory ─ that can be deleted, but that would defeat their purpose; a cache is intended to have information readily available without needing to download or compute it every time. Deleting those caches has to be done manually, but is ─ as explained in the previous sentence ─ unnecessary.

running-in: konsole inxi: 3.3.04`Preformatted text`Thanks for your reply. i got it now clearly.
in home directory there is folder called softmaker. i deleted it once but after again appeared.
Can you please edit this output and either put ``` before and after the output or highlight the output and click on </>?
It makes it a lot easier to read.
AX200 & AX201 are having issues currently due to regression from the linux-firmware package as of 2021. Someone posted about it a few days ago as well.
You need to temporarily use linux-firmware v20201218.646f159-1, this is a package version from 2020-12-18
I got my package from Arch Linux Archive
sudo pacman -U https://archive.archlinux.org/packages/l/linux-firmware/linux-firmware-20201218.646f159-1-any.pkg.tar.zst
You’ll also have to go into /etc/pacman.conf and put:
IgnorePkg = linux-firmware
so that it doesn’t keep updating that package. I’ve been keeping an eye on this Arch forums thread to see if newer packages fixes it, but doesn’t seem like it yet. I do recommend to remove that IgnorePkg after we find out that a newer package fixes the regression though.
SoftMaker Office is an office suite. That directory probably contains its configuration.
The normal convention for user-specific configuration files and/or directories in UNIX systems is to have their names start with a dot/period (".") or put them under a directory whose name already starts with a dot/period, such as ~/.config or ~/.local. This is because files and directories whose name starts with a dot are hidden by default, so that they would not clog up the listing of work-related files and documents.
Manjaro is partnered with SoftMaker, the company that produces this office suite, and that’s why you get the option of installing it. However ─ and I could of course be wrong ─ it is my impression that SoftMaker Office is not a native UNIX application, but rather that it was originally a Windows application that was ported to GNU/Linux. And that would then explain why it doesn’t follow the convention of storing its user-specific configuration in a directory whose name starts with a dot.
Thanks for your supporting. ok will do like you sad. firmware is like kernel or?
Kinda…? In the sense that it contains binary blobs needed for functionality of certain hardware devices. Think of linux-firmware more like… drivers. It isn’t a kernel.
I had installed freeoffice but did not liked and removed it. after i installed Libreoffice and its better than freeoffice.
p.s. what about security purpose? what steps is needed for harden system security? in windows also have to care about it. as i guess in Linux there is no needed that right?
should i add cloudflare dns and vpns etc?
In the broader sense, the term firmware is used for a special kind of low-level software that is embedded into hardware components. Because this software is embedded into the hardware, it cannot be overwritten ─ with the exception of a BIOS or UEFI, of course, because they are stored on a flash EPROM ─ but like all software, firmware can and usually does contain bugs.
The solution to this problem is to load an improved version of the firmware into memory at boot time from within the operating system. This improved version will not overwrite the embedded version, but will take its place as the interface between the kernel and the hardware in question for as long as the machine is running.
This is all up to you. But please make a separate thread for this as it’s deviating from the original question, which makes it harder for other users to find answers to such questions.
i did it and put that code on etc at last end saved.
That’s all overkill. Microsoft Windows is notoriously insecure as an operating system because it was never originally designed to be an operating system; it was designed as a graphical user interface on top of MS-DOS, a single-tasking, single-user operating system for non-networked computers.
By contrast, GNU/Linux is a UNIX-architecture operating system, and UNIX was developed from the ground up as a secure multiuser platform, modeled after the Multics mainframe operating system.
A userspace firewall might be a good idea if your computer is a laptop that connects to the internet by way of WiFi, but other than that, you won’t need it. UNIX does not listen on all privileged ports the way Microsoft Windows does; it only listens on privileged ports that you yourself have explicitly opened by running a service on them, like e.g. an ssh server.
Ok than not will open new post about Security.
Thanks both of you for such kind support. i appreciate that. So because of that i left Windows. i was fed up with care to it as babysitter. i will think only to change system to gnome because of kde not supports fingerprint sensor.
i will test bluetooth if it drops or and let u know friends.
hope i put ```
IgnorePkg = linux-firmware
correctly on etc
Well… don’t forget to install the older package as well
Oh, thanks for info. Now I know why BT mouse losts connection lately.
thank you. when it will fixed let us to know please. i also will have look on that links u provided.
Damn, I switched from pulseaudio & pulseaudio-modules-bt to pipewire today and now I’m also having those bluetooth disconnects.
New firmware with an update for AX200 just hit the unstable branch.
Let’s see how that goes…
