Very Slow Computer

How can I find out what is eating my memory? I've run Task Manager and it shows 18 to 20% of the memory in use and the computer is slow. Delays in typing, cursor movement. The specs are listed below:

I'd run

Code: Select all

dmesg -k
first to see if the kernel's complaining about anything then try

Code: Select all

dmesg -l err
to see all error conditions.
Going through the other logs in /var/log/ might be needed depending on what you find.

Your version of MX Linux predates your computer. Use the AHS version instead.

Lol! I was looking for new topics and found this one and wow, thank you JayM! I have the same issue! My Intel i3 2.53ghz with 8GB ram HP laptop is so slow and even freezing from time to time with 100% CPU spikes. I am running MX 19.2 X64 normal release. AHS was not available at the time I installed MX into this lappy. Wow I wish there was a easy way to "upgrade" to AHS 19.3 cause this is a real pisser. My 4GB ram based towers and ultra small form factor computers all run faster than my laptop with 8GB of ram. Firefox tends to slow it down more but even without FIREFOX, It is too slow now. Virtualbox no longer allows booting into any guest OS without crashing or freezing the host machine. While I know my solution now is to change the HDD to one with MX-19.3 AHS(too much work and files on my system to back up elsewhere right now), I want to put this out there for others that might have similar issues: While MX LINUX IS very reliable, and stable and worth it's weight in GOLD, when the OS and critical libs, get outdated, the OS DOES act up and start getting crash prone. I had to upgrade from 18.3 to 19 to 19.2, and now it seems to 19.3 AHS for the SAME laptop. Why? Cause things started breaking with out warning over time. The system freezes are the WORST.

Ah, I built the computer and stuck the hard drive back into computer and never thought about the newness/ oldness of hardware to software. I will change things.

Thanks

You can add AHS repos then update & dist-upgrade ... (also install the 5.8 or even 5.9 kernel via MX Package Installer)

@Huckleberry Finn, thankyou! I have noted this in my documents and will try this.

This repo was already enabled. Updated the kernel and will see what happens

Well it's showing errors on your 1TB Seagate /dev/sdc
I would try disconnecting it temporarily to see if the issue clears up.

Also you've permanently enabled the test repo. If your system auto-updated since doing that you've probably messed up your MX installation beyond repair and need to reinstall. That's probably what's causing the slowness. You may as well download the AHS iso and install that, unless you're using Timeshift and have a restore point from prior to your enabling test or have a complete system backup from before then, if you restore that you may be able to avoid having to reinstall MX. (See "How To Break Your System", linked in my signature.)

Just a tiny (and humble) addition to Tim's suggestion: If possible, on live session: GParted from Menu: Right-click on sdc1 "Check" .

( While you're at it: Menu: GSmartControl => Short Test. )

Actually: "while you're at it" again: do them for all (drives & partitions), nothing to lose and quick, a kind of "maintenance" :)

Ran the SmartControl=> short test and received a PASS.

I've noticed this slow down of the computer happens over some time so I will monitor it, and when it slows down again, I will retest the drive.
