Ubuntu :: Can't Enlarge Swap / Why Is So?
Mar 4, 2011
I recently enlarged my Root and Home partitions and in the process was left with 1.69 GB of unallocated space next to Swap(see image). Not quite sure how it happened this way but for some reason I was unable to grab all the unallocated space available when enlarging either Home or Root. What I am wondering is there any reason why I couldn't enlarge Swap and thereby use up that unused 1.69 GB? Would there be any minor advantage to this? Also if I did this would it simply be a matter of booting from Live Disc and running GParted with Swap off and grabbing that space?

Is there a way to increase the area around a window that can change its size? When I'm using the touch-pad I'm not that stable (to much coffee) and find it really had to get the mouse to sit on the one pixel that allows you to resize a window. Or another way to resize a window?

The one thing that I can't learn to do is to expand the canvas size. So if the ratio is 3x2, I want to add extra white space to make it 3x3. If I use the -geometry function, it enlarges the image to the proportions I want, but it loses the aspect ratio.
If you turn to page 377 (or 388 in PDF) of the User Manual, under "Montage", you'll see that ImageMagic can do what I want. The thumbnails in the example image are all of different proportions but the alloted space is 1x1 for all.
However the documentation on this function is pretty bad! Does anyone know how to do this?

I am trying to grow my array to make full use of my drives. I have a raid 6 using mdadm on my home server. The array used to consist of 6 1.5TB drives when it was created. Since then I've been replacing the 1.5TB drives with new 2TB drives. And now I have replaced the last 2 drives.
When I added the first 3 disks I did not use the whole disk for the raid partition but rather made it the same size as the 1.5 partitions. As it turns out this may have been a bad idea. (But it gave me another 3 partitions of 500GB that I turned into 1 disk using mhddfs.)
Now I'm trying to grow the array. I've been testing in a virtual enviroment on how to do it but I cannot find another method than this :
1) fail 1 disk.
2) re-partition the disk with the size of the whole disk.
3) re-add the drive as a spare.
4) start the now degraded array to let it resync.
5) wait quite a while. (aprox 5 hours)
6) start again from step 1 for the other disks.
7) use mdadm with grow command to enlarge the array
use resize2fs to fill array to max size
Now although since this is a raid 6, I keep some redundancy but I still worry about degrading the array so manny times and rebuilding the whole thing. I mean I read the thing out 3 or 4 times over doing this.

I've installed fedora on my PC by reducing the existing NTFS partition and installing Fedora on free space at the end of the disk. Now I'd like tho enlarge fedora's partition. How can I do this? If I just move the partition back in disk, can I boot normally on fedora?

I ran a program under WINE and when it terminated, suddenly lots of programs were running with tiny fonts, including Google Chrome, Unison, and PLT Scheme. I think what these programs have in common is they all use GTK. I am running Debian Linux without a Gnome desktop. As suggested on the web, I put this text in ~/.gtkrc-2.0:
style "user-font"
{
font_name="BitStreamVeraSans 14"
}
widget_class "*" style "user-font"
gtk-font-name="BitStreamVeraSans 14"
Unfortunately this change has had no discernible effect.
How can I escape the land of tiny-fonted ones?

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?

First thing I do is double click the top of the window to enlarge it and when I do that the window enlarges correctly, but it also lunches an app like the double click lags behind to click on an app after the window enlages, im using the 64bit version.
If u dnt knw wat I mean please try it out and tell me how I can fix this, just double click a sized window to make it fullscreen and tell me wat happens.
I also would like to knw if maybe its the fact that im using the 64bit version and that its glitchy.

I want to increase the size of my Linux partition (yellow and highlighted in image), which is situated in an extended partition, along with my biggest partition.
When I try to select the options from any partitioning software (EASUS, Paragon, Gparted) the option to resize is not available (or can't enlarge).
For example in the Paragon Hard Disk Manager, I can't add free space before the partition, even if I first shrink the "G:" partition, then try to enlarge the one with Linux.
Do you know what's happening here? Why am I not allowed to resize the partition?

I just installed 10.04 Ubuntu and allow the Manager Updates.
Movie Player and PitVi apps seems to disappear when I load a clip and enlarge the window.
Movie Player will allow a smaller window and the clip to be played but once I stretch the window, it disappear Nope, its not as though I "floored" that window. It's gone.completely.
PiitVi, when loading a clip, once its full loaded, it disappears.
I did try installing and re-installing but same results.

extended sata partition shrunk at 15 partition limit, how to re-enlarge i hit the 15 partition limit, forgetting it now exists for sata drives, thinking i would add more. upon creation of the 15th, it squished the end of the extended partition to meet the last logical partition, leaving a large unallocated portion after the extended partition, which seemingly nothing can be done with, just sat being wasted space. i have since deleted a few of those partitions, but so far have still failed to find a way to recoup the unallocated space back into the extended partition.
[URL]
if necessary, i'll do it the painful long winded way of backing up and starting the extended partition again from scratch, but i really rather wouldnt have to do that. i'm sure there must be a way of telling the extended partition to once again reach the end of the drive.

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

My motherboard supports up to 8GB DDR2. I currently have 4GB installed. If I maxed out my RAM, and installed 10.10 without a swap partition, I've heard this would increase speeds significantly. Would it? This particular rig runs multiple servers including an Asterisk PBX with FreePBX, XBMC, and Boxee. XBMC and Boxee do not run at the same time, only one at a time. Would it be safe to run with 8GB ram, and no swap partition? Running FreePBX/asterisk, XBMC, playing videos or ....., and every other background processes, free shows on average 50% free. Opinions?

what exactly are my 'swap 3.1gb' and 'extended 3.1gb' partitions for? are they necessary? what would happen if i deleted them? do they have to be that big (thinking about loading ubuntu to 20gb HDD partition, but at 6gb for the other stuff, #ouch#)? What does ubuntu do about very low space when installing (i.e. in reference to the 20gb part)? why does ubuntu have these but no other Operating Systems do? Would i lose any performance without them?

I am getting a new SSD for my laptop and I have been researching the different tweaks for an SSD. I still have a question regarding the swap partition: is it better to not have one for an SSD? (I have 4GB of RAM...)
If I don't, how would I specify it during the installation process for 10.04?

I have 1GB ram and 2GB swap space. It seems that linux programs somehow are aware that there are 3GB ram avaialable and pretty fast uses more than 2.5GB. System becomes unresponsive because of excessive swapping. On the other hand if I disable swap, using the same programs (chrome, vlc, openoffice) I get only ~600MB use while watching videos and browsing net.
I know, that linux uses all available ram to enhance performance, but in my case, it really hurts the performance. I also cannot leave the swap off, because I sometimes want to do some 3d editing, and then the memory usage can exeed 1GB.
So basicly my question is, if it is possible to force swap usage only when really needed, and make it so, that swap is not considered free ram and filled up with useless junk. (For example, if swap is enabled VLC player just loads whole movie into swap! - which of course is useless, because movie is located on the same hard drive, but VLC is not the only offender)

When i first installed ubuntu about 2 weeks i left about 30gb left for windows vista. I have not used vista at all so i decided to delete it and use the whole hard drive for ubuntu. I got the liveCD out and went into the partition editor on that (i had ubuntu,swap,vista in that order) and deleted the swap space and vista and increased the size of the Ubuntu partition to so there was only 4gb left for swap. I then booted up again from the hard drive and i get this message "one or mounts cannot be mounted" or something to that effect and it talks about the swap partition and offers to boot in recovery mode which does work.Once in recovery mode i go in and try and make swap partition with Disk Utility and i do that and it works. I go to restart Ubuntu to test it out and the same problem happens again, cannot mount swap ect. so i go back into Disk Utility and it now says 4gb Unrecognized instead of swap
