I think with your suggestions i've solved my issue.

Many thanks!

Hey guys

I have just flashed my pc with a fresh install of manjaro linux, and there is this unwanted annoyingly audio ramping feature  that keeps on bugging me.

I'm not sure how to explain it, but basically the audio levels start low and rise up whenever a new/paused audio source begins streaming audio.

On my old install,  I remember tweaking something in the pulseaudio config file to remove this, but I seem to have forgotten what that was.

I of course tried remembering and googling, but so far I haven't found the one that I'm looking for.

Hello guys,

How do external gpus control their rgb lights? I'm running on linux with a palit 1060 6gb gpu, and unfortunately Palit doesn't  offer a solution for us linux users. 

So my question boils down to: Can i hack my own solution and have rbg control via some driver/interface/api, and if not should i even consider going and asking palit for help on this. And lastly if everything else fails, would you have anything against me going and modifying the header pins (which connect the rgb) to the board.

Can you clarify your issue? Is your PC not getting gigabit speed or is your Pi not getting gigabit speed? Keep in mind that Raspberry Pi's don't have gigabit networking.

AFAIK the rp 4 model b specifically has gigabit networking.

Seems like its running at 100mbit. This is probably due to a bad cable as you only need have the connectors for 100m. Did you try a new cable?

You are absolutely correct. I'm not sure how I didn't think of that. Both if my cables are old cat 6 cables, but one of them was extra cheap when I bought it, so I suspect I got scammed. I figured it out by switching the cables around, as I do not have a third one. Right now, my pc has gigabit, but the pi has decreed its speed down to 100 mbs/s. So most likely if I want full speed, I'll need to grab another cable. 

Thanks for the suggestion

It's in the text. I specifically said that I'm unable to get gigabit speed with my motherboard's e ethernet controller 

Hello guys,

I'm trying to make this as  quick and simple as possible:

The problem I'm facing is primary  the fact that I'm unable to get full speed out of the  advertised speeds by my motherboard/router.

Here is the setup and environment.

This is my freshly installed OS - source :neofetch

Motherboard Ethernet controller - Realtek® 8111H. I installed the driver and rebooted the system before attempting any tests

I have the following output from

'ethtool eth0'

So here are some questions:

1: Why does my pc's speed report 100Mb/s even though it advertises 1000baseT/Full. As far as i can tell, the only difference to the raspberry pi is that the pi has the 1000baseT/Half.

2: Is this a driver(missing/faulty) or a controller(chip) limitation or something else entirely?
3:What do now?

I think the picture is pretty much self explanatory.
My Google chrome links (<a> tags) are completely different color than what they used to be yestarday. They were saturated blue and not this washed out color today. I'm not sure if i caused this or if it was an update or something. 

Does anyone know of a fix our the cause of this?

it's generally recommended to install Windows first since it usually overwrites the EFI boot partition with its own bootloader and doesn't recognize your linux system. This can also happen after a windows update, which is why I don't recommend dual booting on the same drive. You can use your installation drive to chroot in your manjaro system and reinstall grub manually, that should fix the problem at least until you update windows.

Hey,

Thanks to your suggestion and sweat and tears on my part, I was able to update my grub and recover my OS! 

However, I must note that operating systems such as Linux or Microsoft never fail to amaze me by their sheer complexity. I had to follow and read close to 10 forum/articles/guides on recovering grub and some other things like mounting partitions, EFI variables, and much more related to this topic that I had to use in order to recover the OS. Still, I thank you for your suggestion.

You are the only reason I did not have to go through reinstalling my OS and the software on it, thank you!
 
Cheers,

Hello guys and happy new year!

Here is tldr of what happened:
I needed to play a game with my buddies which was not compatible with wine (did not ran), and i decided to install windows and dual boot.
Problem was that my boot drive was only 1 partition and i had to resize it. To do so, I installed a boot-able linux on a usb stick, booted from it and resized the boot drive.
Before installing windows on the new partition, i checked if my main os (majaro) still works. And it did, i was able to load the os normally.

Sadly though after installing some application on the  windows side, i was no longer able to get back into manjaro. I was stuck at grub rescue.
So far I've only tried to follow this yt tutorial but with no success.

As a last resort, I've flashed another usb with manjaro and i'm ready to reinstall my linux os, but i come here as a last measure of trying to recover it.
Any ideas, suggestions?

Thank you for your time reading this!

Hey guys,

I have a general new-bie question about VPNs

I understand the general idea, people want to stay anonymous by using the VPN server  as proxy to hide their identity.

What I do not understand is why people keep on talking about the idea  security.  

It's said that if you do not use a VPN, many users may use that to their advantage to snoop and exploit your data traffic.

Well, are we just going to pretend that HTTPS does not exist?
But that is clearly not the case, since if that were to be true, there could never be any sort of online backing and document management services.

If you need access to a PC, why not use SSH, if you need access to the file system why not use some form of SFTP client.
To me, a VPN seems only useful for changing your geo location and bridging into a foreign local network.
Given the hype for VPN services nowadays, I'm sure i'm missing some key feature.

So please, tell me why they are so useful.

I was referring to the "swappiness" value, which determines how aggressively Linux moves data in and out of swap space. Most desktop distros have it set to 60 by default. You can try changing the amount of swap space to see if that helps, although it's not recommended to disable swap entirely, as programs will expect there to be swap space.

 

Manjaro is based on Arch. Here is the relevant section in the Arch Wiki on how to change the swappiness value: https://wiki.archlinux.org/title/Swap#Swappiness

 

The reason I think this might be an issue is that your swap space is clearly full, and a higher swappiness value might be causing the OS to keep trying to move data into the swap space, but there's no space to move it to.

So, what solved my problem and allowed me much more flexibility was setting up additional swap space by following this guide here.

I even set up a `watch -n .2 free -h` just to monitor what exactly is happening to each memory type as I was trying to stress my system by opening an unreasonable amount of processes.

I can confirm that buff/cache IS being reduced as free ram is being depleted and then it's allocated as being used.

The test was made with `swappiness` of 10, and a swap size of 16gbs. No studders, no freezes, nothing.

I'm just left wondering now, what exactly happens to the swap data and how should it behave on paper?

From what I can see, the swap space is not being emptied even though there is 8gbs of system ram available for use.
Why does the data stay on the swap and it's not moved back to system-ram?

Is there a reason your swap file is so tiny? Linux usually expects the swap file to be at least as large as the amount of RAM. If you want to avoid using swap, I'd recommend reducing the "swappiness" to a low value, like 10 or even 0, to encourage the system to not use the swap space.

Besides the visual appearance of my host, I have tried to stay away from making any changes to system configurations that I do not understand the purpose of. The setup is exactly like the stock install of manjaro KDE. 

As per your suggestion, I will both turn off swap and will also try low/high values for the swap space in order to see if anything changes in the behavior of system-memory.

Hey guys,
 

So I've recently made the change to switch over to Linux. I have to admit, besides game support and some key software, Linux is the girlfriend I've always wanted but was too scared to approach.

However, recently it has come to my attention that she is getting quite fat, and I'm not sure what exactly she is eating.
 

Ok, so the main problem and concern is that Linux is eating up all of my memory, and I don't know exactly what is causing this. - And yes, I know I should open the system monitor and take a look at which process is gulping so much memory, but honestly, they are all on a diet. You can take a look for yourself in the pictures below I have taken an image of the output from :
 

free -h

And from system monitor (sorted by memory)

And here is the output from free -h

I fail to understand where exactly my memory is going.

And before you say, "The memory you see as `buff/cached` in  the output of free -h is a form of  memory used as a cache (as the name implies) to speed up your system, and that specific memory  will be freed when a new process requires more memory than there is currently free  memory available to the system"

Well, I've already read about this on the web, but my system literally freezes when the sum of used + buff/cached exceeds 15.6gbs.

I wish I was making this up. If I had to give an example, then if I were to open: 1vscode instance, 1 chrome instance (10tabs), unity editor + hub instance, and a discord instance then my memory is full and anything beyond that will freeze the system up.
 
The goal of this post is for me to understand a little bit more of how Linux memory works, and perhaps attempt to troubleshoot my current situation in hopes of finding some kind of fix or remedy.
I honestly love Linux, but at the current moment, I cannot multitask as I would on windows ( on windows I could do 4x the amount of workload before I would hit the swap memory on the disk)

Thank you very much for your attention and time. 
Cheers!

Hey guys,

So today I bought a brand new SanDisk ultra 32g.
I inserted it into my system and I instantly opened CrystalDiskMark to check the  device's speed.

After it finished, I opened the device and i found 2 files there. [SanDiskSecureAccessV3.1_win.exe, SanDiskSecureAccess Settings]
I was wondering what it was for... so I opened the .exe file and I setup a password.
2 Seconds later the device became write-protected and I CANNOT delete, format, delete the vault that was created, move files, or load files into the USB. (basically it became inoperable & useless to me)

I tried contacting SanDisk support but they said nothing can be done and I should return the device.
I tried some basic "diskpart.exe" commands but nothing helped. [select disk# > attr disk clear readonly]  - No luck there.
I also tried poking around inside of the vault program ~ it looks something like this image. There is no option to delete the vault or revert the changes. (at least to what i could see)

So here I am, in a time of great need, I reach out to you guys.
Is there any hope? I sure "hope" to hear from you guys soon!

 

So I was choosing my next SSD and while browsing I noticed that the site I'm shoping on does not include this information.
So i googled a few models and I found some reviews that said conflicted things.
The models I'm looking at are : SP 512 GB P34 A80 M28, and ADATA XPG SX8200 PRO 512 GB.
A random reddit page claimed on the silicon power not having any cache ~ so I looked the main page of the manufacturer and I found information that confirms Buffer cache.
So... I was confused to say the least. Can you guys shed some light?
Thanks.

Alright so, I own a 29" ultrawide monitor and I'm planing on purchasing a  second 27" one. I also have limited desk space, so I was looking into dual arm mounts. 
So, the question is: will a 27" vesa mount be compatible with my setup, or do I need to step it up to a 32"? 

So, we basically all know that IPS is just an all around better panel than TN ~ better colour reproduction, viewing angles and so on.
But here I am, choosing my first 240 monitor and I just stubble upon some models that do not make sense to me.
How come in my country this IPS  panel is 50 bucks cheaper than this TN panel, or about 150 cheaper than this TN panel.
I mean, in the past I used to know that TN is generally cheaper, faster in terms of response time and refresh rate but it seems that these stereotypes are gone now.?
So what exactly is the difference?
Also, can i please get your opinion on these models?

• ASUS ROG Strix XG248Q 
• AOC C27G2ZE
• Dell Alienware AW2521HF
• LG 27GN750
• Samsung C27RG50FQU
• Lenovo Y25-25

Thank you for your time.
