  • What is a “Swap Area”?

    3 answers



I installed Ubuntu in dual boot, so I have one partition for Windows, and another for Ubuntu. However, when I check the partitions I see that I have 6.3GB of space formatted as Linux swap. I do not know why I have that partition. Can I format it to use?



partitions in Disks utility

Linux divides a memory into chunks of memory called pages. When your system needs more memory than you have available, the kernel swaps out less used pages and gives memory to the current application that needs more memory and also it is used to store pages that a application on startup that used only on startup and never used again.



A typical swap partition should be double the size of your memory.(However, The size we can give to swap entirely depends on your RAM and your working processes)

    Swap space is the Linux equivalent of a Windows page file. It's there for preventing out-of-memory situations.

    • Thanks. however, does the swap space has to be that large. I only have about 50GB of my ssd for Ubuntu, and it already took more than 10% of the total space.

    • There's no hard-and-fast-rule about how much swap you need since it depends on your needs. If you have >= 4GB of memory, it's probably safe to shrink the swap partition down to 3-4GB.

            How to enroll fingerprints to Ubuntu 17.10 with VFS491

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 1 down vote favorite I decided to switch from Windows to Ubuntu 17.10, I meet it like 8 years ago and I didn't decided to switch until now (haha). Well, my actual device is an HP Probook 4540s with a Validity fingerprint sensor (VFS491). The fingerprint sensor worked fine on Windows but I can't get it to work in Ubuntu. The device is recognized as 138a:003d but is not detected as a fingerprint scanner by some apps like Fingerprint GUI. I want to use the fingerprint scanner to log in into my user account in Ubuntu but it doesn't supports fingerprints without special software and the drivers of the fingerprint scanner are available for Windows but not for any Linux distribution. I found something on GitHub (https://github.com/eekpie/libfprint) about the integration of the VFS491 in libfprint and I think it can help but I don't know what to do with it, so that's why I need the help of the community to do it since I am...
