Increasing Entropy size

I recently switched to Multimedia version and so far I'm loving it, but everything starts stuttering after a while. I only see Entropy at 98% and I'm wondering how to allocate more to it

It is next to impossible for us to help you without properly identifying how your system is setup.

I am posting a link to the Garuda Wiki where you will find out how to post the information required to help you:

The section to pay close attention to is the inxi command.

Please post the required output(s) within a reasonable period of time or your help request will be moved off the main forum to an unfrequented backwater channel of the forum.

This is because help requests that include no information are of no use on the forum. Permitting posts with no information to remain on the main forum only encourages other users to think it is acceptable to post similar help requests that can never be solved because of lack of info.

If your post is removed from the main forum you will now know why. If you edit your relocated thread and provide the required info, your post will likely be returned to the main forum. To edit your post press the three dots near the bottom of your post, then press the pencil icon. This will allow you to perform an edit and include the information we require to help you.

We have this already active & 98% is quite a lot? I dont understand this request.


Are you sure this is the correct question?


No, I was basically dead inside after installing LineageOS so I just posted this and went to sleep, sorry about that. Everything runs smoothly until Entropy hits around 98% (usually at around 93%) when I'm multitasking, so I'm searching for a way to decrease usage/increase capacity if that is what I'm supposed to do

Normally, more "entropy" means the pool is contains more available bits for use, so more is normally better. Exhausting the available entropy pool is normally when processes will stall.

So, two questions:

  1. what are you checking to determine "entropy"?
  2. is this simply a symptom of a different issue, e.g. have you looked at top and iotop to see what else the system is doing?

On multimedia edition there is monitoring thing on the right side of the screen. I have 4096 entropy in total, Fxx is also added on the edit
I'm looking at both top and iotop, but I don't see anything going nuts even at 97% (I'm only looking at CPU, MEM, DISK READ, DISK WRITE, SWAPIN, IO).

I still fail to see the issue here. Entropy is already increased by haveged?

This kind of implies that the available entropy value is not related to the issue you're seeing.

Keep watching top and iotop to see what happens when the issue occurs.


When I'm using multiple programs and tabs everything becomes laggy. Cpu and ram are more than fine, but it's always happening when entropy reaches around 98%

"Entropy" is very likely the wrong direction here. haveged refills the entropy pool so the issue is not a lack of entropy.

The fact entropy hits 98% is more likely an indication of a process stalling and allowing available entropy to reach that point. That is, it is a symptom.

I'll do some digging then, what tabs in top and iotop should I look at?

Neither of those programs has tabs?

You're looking for anomalous behaviour that occurs around the same time you see the issue, e.g. high CPU and/or high IO use by a process. You might also look at network usage with e.g. iftop.

I meant those lines like cpu and etc, I'm not native so I occasionally butcher thing or two

All of them. :wink:


What about PR, VIRT, RES, SHR in top? And can you take a glance at this? Just duble checking if everything is ok

top - 14:57:30 up  1:13,  3 users,  load average: 1,66, 1,89, 1,96
Tasks: 231 total,   1 running, 229 sleeping,   0 stopped,   1 zombie

Update: Noticed cpu spike on latte-dock process (30-60% cpu usage) and xorg (20-30% cpu) when minimalizing and maximalizing windows and consoles

I can't tell you what to look for. You need to observe the system running in a normal state.

You will see occasional CPU usage as programs do things - that's normal and to be expected given that's what a CPU is supposed to do. However, you can watch for a process constantly running at 100% or more.

Same for RAM usage - programs need RAM, so will use RAM, but you can watch for processes constantly taking up more until the RAM fills.
