Ubuntu :: Remove Unused Swap Files?
Jul 12, 2010
According to System Monitor, my hard disc has a total size of 107.2 GiB, of which 6.7 GiB is "Free" and 1.3 GiB is available. I'm not sure if this is normal or not, though I know at least part of this wasted space is taken up by at least two failed attempts at creating Swap Files. Ubuntu says I have no Swap space whatsoever, so is there any way I can delete all these failed and unconnected Swap Files so that I could free up some spacend hopefully create one working one

How can I remove an unused desktop? I am currently running Unity 2D. I can't run 3D, so I would like to remove it. Also, I want to try out other desktops so I will want to remove those (or Unity, depending on which I like better). I read somewhere that just doing sudo apt-get remove kde won't actually remove the entire desktop, so what else should I do.

I'm trying to Dual-boot Windows and Ubuntu. I have Ubuntu now. I'm trying to remove space from the Ubuntu partition(Active) but, it won't allow me to remove space from active partitions. I have 11GB Free according to GParted, yet during the installation it displays only 8MB Free. Oh, and I'm trying to install Windows XP through VirtualBox. Is that possible through the install CD? I've been searching and haven't seen anything about it.

I haven't tried any random password patterns yet but I have tried knoppix because of a suggestion and it didn't work. I am useing knoppix as my OS not from CD or DVD. I would like to add and remove unused or needed apps. My linux language is week for the time being so I use the Software Center option from the Preferences option from the Main Menue.When I click on the remove icon a screen comes up asking for the Authentication Password and I don't have it, I as can not change the time on the desktop because it says that I am not the owner. How do I reset all the passwords and regain complete control of my system

Running # lsmod | grep -e " 0 " | wc on one of my servers running CentOS 5.5 (64 bits) reports me 32 unused modules, I mean, modules with 0 references. Am I wrong interpreting these results? If I'm not, how can I automatically clean those unused modules (i.e not manually running modprobe -r ). Some years ago there used to be a daemon called kerneld who was in charge of that task, right? What's CentOS new equivalent?

When you unsuccessfully try to install software, does your Slackware system become cluttered with unused files? Is there a program, other than 'slackpkg clean-system', that can review your installation and identify any useless stuff? My tmp directory is set, in fstab, to delete its contents on boot. Is the tmp directory the only directory to be concerned with?

I want to remove my swap partition. Probably one I would have to boot into a rescue cd and remove it, but aside from that is there any other consideration or commands that I need to be aware of?

I have a rel 5.6 system that we just added more memory to.
1. What is the correct or best way to increase swap?
2. Can I remove the swap space later on?
3. How do you remove it when done?
Our rootvg only has 8G available to it and I want to be sure if i allocate anything out to it I can reclaim when done without having to rebuild the system.
We have to do a lot of data moves so we allocated extra memory to this VM system and now we need to increase swap. I did see several articles in google but they describe using a new swap partition, a swap file and increasing an existing swap space. I am still not sure what is the best way to go knowing this is a temp situation.

As mentioned in "man swapon" priority value is between 0 and 32767. BUT usually if we add swap devices without giving the priority, their priorities are set as -2, -3, -4 and so on; values which does not fall between 0 and 32767.Why is it so ? Any ideas ? However, I know we can change them through "swapon -p". But, if do not wish to do so, it uses -2, -3, -4 only. Like below,
Code:
[root@server ~]# swapon -s
Filename Type Size Used Priority

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 have Ubuntu Meerkat (10.10) running on an Inspiron E1505. I have it setup for dual boot with Vista. I installed Kubuntu on top of Ubuntu and now have a blue Kubuntu system loading screen where it used to be purple.
I've installed a lot of programs, most unnecessarily, so I'd now like to get rid of ALL of the unnecessary programs and associated packages or dependencies. I'd also like to get rid of KDE, and any Ubuntu packages I never use.
Is there a quick and relatively easy way to do this?

Now i want to remove all the files on the Ubuntu 10.10 and also remove the boot screen that comes up asking me to choose.

I am still a novice with Ubuntu and I am trying to write a shell script which will clean redundant files. I am stuck with one line where I would need a command which will remove all files from directory except some of them. Can anyone please advice how to add such an exception to the rm command? I have searched some bash shell tutorials, however, no joy. Guess I have overlooked something.

I seem to have a strange problem with disk usage on my linux partition. I just upgraded my 10.04 to 10.10 and I'm not sure if this was there before.My nautilus tells me that I have 1.4 GB free on my linux partition. My partition editor (GParted) tells me that 79.31 GB of my 81.38 GB is used, and I've 2.08 GB free. There's no way I've got that much stuff on my linux partition, and to confirm it, I ran the Disk Usage AnalyzerApplications/Accessories), and the total size of everything on that partition amounts to much less than 10 GB.
I've tried deleting all my trash (both root and user trash) and I looked at all the folders trying to find any suspiciously large ones to no avail. I thought it might be some weird bug, but removing some files, added the correct amount of space to the free space detected by nautilus. I have no idea what eating up my disk space.

I wondering does the evolution-alarm-notify and evolution-data-server-1.4 would remove from the system monitor or just leave them alone. I didn't want to touch them that would cause system diseaster, can you please confirm for both if say yes to remove that will be good safe.. I am running older version of Ubuntu 5.10 on my lappy.
My firefox browser takes too much memory that runs very slowest and I need to cut down the both program list above or what I need to remove some other program in the system monitor.
