I looked at the inxi and the PC has 3.16 gb of memory. Has it got 2 x 2 gb chips? If not, adding a 2nd 2 gb chip might be a cheap way to reduce swapping. Another opportunity to improve swapping performance would be to upgrade to a fast SSD instead of the 7200 RPM HD.
If not then make do. Find out which programs are using the largest chunks of memory and substitute lighter alternatives as much as possible.
Encrypted swapping on an old PC is going to be quite slow. Slow because it is swapping out and in to a HD at all. And slower because it needs to encrypt it before it goes out, and even slower because it needs to decrypt before it comes back in.

Based on the replies, I think your best solution is to run very light apps and not need any swap to worry about.
Swapping is inherently slow. Encrypting anything will make it even slower. You don’t have a rocket fast machine. Use sudo ps_mem.py to analyze what you are running and try to find lighter solutions that are acceptable.
I agree with you Bob. For as long as I can remember, I’ve rarely had to actually use swap.
Once a long time ago I had a Dell Dimension 4100 desktop computer. When it was new around 2000 it was a capable system, and it certainly was reliable because I got close to a decade of use out of it. I do remember that if I ran the KDE desktop as it aged, it would gracefully swap, and it’d only allow one or two apps active, particularly if a memory consuming Web browser was running. That’s when I probably used antiX most; it worked fantastic on that old desktop, and of course I’ve continued to use antiX, as I am right now…
Since that old desktop I’ve never seen swap in active use since… at least not on any of MY systems!

Maybe always running shred command from an alias on your swapfile before leaving the system unattended and before shutdown
would be an option. You could call the action from an icon in taskbar easily.Even swapping to volatile memory such as ram is not completely risk free, with an expert around, he might
freeze the system to preserve data. Sounds like he needs a short sharp kick in the right place to calm him down….PPC
I followed the instructions you posted, and the system keeps freezing when it starts swapping
I assume you did read my post that mentioned that probably current Linux Kernels do not work well with encrypted swap files, and that if you wanted encrypted swap it would be advisable to use a swap partition, not a swap file? Did you try using a swap partition? If so, does the problem persist?

Encryption consumes CPU-time and memory, so it is a vicious circle if computer swapping trying to encrypt swap.

How about if you run
sudo chmod 0600 swapfile0What should keep the security expert assumed from reading its contents anyway, just booting the PC with a disk analysing tool instead of antiX?
Using unencrypted swap is dangerous.
Yes, sure, if your device is not physically secured by locking it up in your apartment all the day…
But you might get still away when following the additional hints for setting up encrypted swap files given here:
https://wiki.archlinux.org/title/dm-crypt/Swap_encryption#With_suspend-to-disk_support
In these instructions some common pitfalls are treated, so check out also what the links to known issues and missing prerequisites keeping encrypted swap from proper working suggest, and check what their warnings read.
Just keep trying.
Maybe @anticapitalista can give you some hints whether the swap is encrypted also when setting up antiX encrypted using the defaults in antiX installer.
Robin, I followed the instructions you posted, and the system keeps freezing when it starts swapping (between 40 and 80 MB). Unfortunately I was not able to resolve the issue.
Is the problem my processor? My processor does not have AES by hardware.- This reply was modified 20 hours, 32 minutes ago by Pelucia Siffred.
Could you put the swap on a USB, and eject it when done?
BobC, Putting the swap file on a flash drive could slow down the system, and the health of the flash drive could be impaired.
Thanks for the idea.In reply to: What are you “here” with today?

@rokytnji: Something seems a bit off with your battery charge percentage.Yeah. Probably because chinese cheap as you can go product… I don’t sweat it.

How to Search for AntiX solutions to your problemsHow about if you run

Nothing. The only way is not to use swap and install enough ram-memory, and glue ram unit into motherboard.

In reply to: GUI to manage (essential) IceWM settings
There are some important zzzfm features that need my attention, but my focus went to fixing and adding a few more features to the IceWM Manager GUI script:
Fixes:
– It now always starts maximized
– The function to change Themes is not perfect, but I removed a bug that allowed for an empty space at the top of the list of available Themes, that had unforeseen effects, if clicked…New features:
– Added a “Show collapse button” to the toolbar toggle – this is very handy on small screens, like netbooks, or screens with low resolution- it allows the toolbar to be rolled up instantly to the lower right side of the screen, releasing screen real-state without “auto-hiding” the toolbar.
– Added a not so well named “Show only used network devices”- what this does is fix the default Icewm toolbar configuration, that shows “info squares” for each of the available technologies to connect to a network- if your computer has a Ethernet card and a Wi-Fi card, by default, the system tray will show a square with info on each of those cards- which for me, does not make sense- most people only use a kind of network connect at a time (either cable or wireless connection). This option, when on, makes the toolbar display only info on the network connection technology that is being used – releasing a bit of toolbar space and making the info squares easier to read (by default I use only 2: network and CPU/RAM/SWAP)Note: if this new version of the script is accepted by anticapitalista, the names of the 2 new buttons will have to be localized- thankfully, this is easy, since all text is inside variables- this means only 2 new texts will have to be localized, no further change is needed. To get the correct translation for “Collapse Toolbar”, please run the script and enable that feature. If you over the mouse over the arrow that appears next to the toolbar clock, a tool-tip will show the exact translation for that feature…
Please test the new script, the only changes are those referred above, everything else remains the same.
