Ubuntu :: How Disable SWAP Drive In 10.10
Mar 4, 2011
The swap partition I think is the reason why my PC with 512MB of RAM is faster on Windows 7 than it is on Ubuntu. I'm not really a newbie on Ubuntu. I've used it for a year.. Never had to disable swap until my laptop broke and I had to settle with this junk.I also have Intel 865GV chipset graphics card. If that may have ANYTHING to do with my slow computer, then feel free to say something but I'm mostly just looking for directions to disable swap partition.

So from a web server stand point if we start using swap for httpd or mysql its bad and performance goes down the drain. So would it be a good or bad idea to disable swap entirely?

I am concerned about the LiveCD touching my HDD at all. Is this a factor, such as using HDD space for a swap file? I thought the whole thing ran off my RAM. Anyway here's my specs:
MacBook Pro 500GB:
HFS+ Partition w/Snow Leaopard ~400GB
NTFS Parition with WIndows 7 ~100GB
EFI Partition ~200MB
1) Does this mean I have a "swap file" on there I don't know about? I assume both WIndows and OSX use virtual memory to manage RAM when running in their respective operating systems but does that mean Ubuntu LiveCD will use one of my winows or OSX partition's "swap file"?
2) Or is there an invisiable partition created for LiveCD to use on some unallocated space on my HDD (I don't think there's any but idunno)?
3) How can I be sure the LiveCD is not writing ANY data to the HDD? I don't believe I have ever explicitly created a swap file in either OSX or windows.

As my harddisks are completely full I want to swap a 1,5TB drive with a 2TB drive to give me some breathing space. The 1,5TB is part of a LVM spanned volume. My simple question, how do I move all data from the one drive to the other drive without ruining my spanned volume?

I was reading this tutorial & it shows swap at the beginning of drive. [URL]
Although I've already installed slackware & put the swap at the back of os, I would still like to know the benefits and purpose of putting at the beginning.

I'm a "new" Linux user, have been using Ubuntu for the last year with no problem but I decided to try out a different distribution to get more experience. So I decided to go with openSUSE (which I have been using on a VirtualMachine back at work). I have download the ISO, created an liveUSB (because my laptop dvd isn't working properly) and wanted to install openSUSE on the hard drive partition where currently Ubuntu is. So, I suppose that in order to do this I should choose the option "Import mount points" and select the Linux partitions (drive and swap) and that would be it.

Been doing some installations in a newly upgraded machine where I'm setting up two instances of 8.2 in slightly different configurations.Installing from netinst AMD64 DVD with firmware non-free. First installation goes smooth as then the second changes the UUID of the swap partition, meaning that the first then can't find it. To add insult to injury the second installation doesn't install GRUB in the MBR of the HDD.
Nothing different or special about the installation which is standard graphical with manual allocation of previously set up partitions. I don't touch the swap drive in the partitioner - just point to the correct partitions for / and /home as I want them. This is exactly as I've done before, many times.Setup asks me if I want to install GRUB in MBR and I answer "No" (because it would otherwise load in MBR of sda where I want it on sdb) then point to sdb in the next screen. Again really nothing different to what I've done dozens of times.

I installed Debian 8 Jessie with full disk encryption and chose to have everything on the same partition. After install, I notice that my 8GB laptop has a 16GB swap. Is there a way to reduce the swap to 8GB (or maybe 4) whilst not affecting the encryption?
I have a 1TB HDD so space is not an issue but I dislike such waste. The setup used LVM.

I got a new laptop, a Dell D400. I want to swap my hard-drive from my old laptop into the new one, and did so... but then got an error stating that my CPU didn't support PAE.
As far as I was aware I hadn't actually installed a kernel with PAE enabled [as I always pick a real-time kernel for audio work]: but then read that lots of the newer distibutions are enabling PAE by default [which is what's caused the problem].
Is there an easy way of disabling PAE in the existing kernel? Or would it be easier to downgrade to another version of OpenSUSE? I'm on 11.2.

Saw a reference to putting the swap partition on a separate drive--just minutes after I was considering that approach. Can't find anything recent on the topic, so asking: Is there an advantage to having /swap on a separate HD from data on /home? My thought was that both disks could be active at once, perhaps speeding up a busy application.

Let's say that software is written that treats a network drive as a swap drive.
Further, let's say that this network drive is not a hard drive on the server but it is a chunk of memory treated as a filesystem in other words a ramdisk on the server.
Given the bottleneck of gigabit ethernet that is used for the link, can anyone predict the likely practical bandwidth of this swap drive in MBytes/s, and crucially the latency in milliseconds?
The reason for this imaginary setup is outside the scope of the linuxquestions forums, please answer on the likely performance only.

RAM for older machines like I use is fairly cheap these days. But flash memory is just as cheap or cheaper. So I'd like to ask about the feasibility of expanding my system's memory using flash memory. And about whether creating a partition for swap on the flash memory, or whether a swap file on the flash device, is the better way to go.
By flash memory I have in mind mainly USB sticks or what are sometimes called "pen drives." But I do also have CF and SD cards that, with the proper cheap adapter (one of which I already own for adapting CF) could be used to create extra swap space. So, what is the current consensus on the feasibility/advisability of using flash memory for swap? I've read about the limited write cycles of flash being an argument against using it for swap. But recent reading indicates to me that the limited write cycles problem applies mostly to older, smaller-capacity flash memory. Some will come out and say that, for larger-capacity flash memory, the life of the device is likely to exceed the amount of time your current computer will be useful (I think I've seen estimates in the range of 3-4 years life--minimum--for newer, higher-capacity flash memory).
A more persuasive argument I've heard against using flash memory for swap is that access times for these devices can be much slower than SATA, and maybe even IDE, hard drives. That would certainly dictate against using flash memory for swap.
So, how about some input on this issue? Anyone using flash memory for swap? If so, what kind (e.g., usb stick or SD/CF)? Are you using a swap file or a swap partition? How's system performance? Likewise, has anyone had flash-memory-used-as-swap die on them? The consequences would undoubtedly be dire. Also, has anyone measured flash memory access times to confirm or refute claims about slow access times? Are some types of flash memory better/worse than others in terms of access times?

I'm dual booting Ubuntu 9.10 and win7. I have an NTFS partition on my disk and whenever i want to browse files on that partition I'm required to enter my password. my problem is that my music folder is located on that partition, and as a result, whenever I open rhythmbox, it cant access the files on that partition and begins to remove them from the library. in order to prevent this i must browse to that partition manually and enter my password upon request, prior to opening rhythmbox.
on a side note - shouldn't the spell checker on the Ubuntu forums recognize "Ubuntu" as a legit word ?

I have one RHEL server which is placed near a corner of the server room. Few people are using this server to watch movies and unwanted photos. I want to disable access to CD ROM. disabling the eject button of the drive wont work, as they used pin to force open the drive tray. Can I delete the cd rom drivers from the hard disk so that no CD will be detected ?

In Fedora 15, when I plug a USB drive, Nautilus will automatically open and show whats inside of it. I'm working in a project where I have to plug and unplug USB drives many times, and Nautilus opening every time is really annoying. I tried to use gconf-edit and set the keys apps>nautilus>preferences>media_automount and media_automount_open to false, but it didn't work.

I'm testing OpenSUSE 11.3 on a server and I'd like to disable the write cache on all of my drives. In Ubuntu Server I was able to accomplish this with hdparm by adding the appropriate settings to /etc/hdparm.conf
As far as I can find the only thing that OpenSUSE offers is /etc/sysconfig/ide which allows you to force particular DMA modes. I could just put the hdparm commands in /etc/init.d/boot.local but I'd prefer to do it the right way if there is a right way to do this in OpenSUSE.

I am just wondering why KDE never uses my swap. On the KsysGuard, It reports that I have a GB of swap that is never used. I have 2GB of ram. This is only an issue because VMware will take up half of my computers resources for itself if, in the event, it needs to use it. How do I change this so my swap is being used. I have: Kubuntu 8.04LTS
