Ubuntu Installation :: Swap File Management Or Downgrade

Jun 28, 2010

Alright, I just wanted to see if this would even work, so I installed Ubuntu Lucid Linx 10.04 on a 2001 Sony Vaio with 1.7 Ghz. Intel P4 processor and, yes you're reading this correctly, only 256 MB of PC2100 Ram. I dumped in my own PCI wlan card and 64 MB Radeon 9000 Pro AGP card, then I did the installation.

Although I already ordered 2 mem chips (512 MB each) for this system which will max it out, I also created a 5 GB swap partition since I figured that this would greatly enhance the installation and consequent usage thereafter. Now mind you, the installation of 32bit Lucid worked like a charm. Slower than normal, but like a charm. Wifi is working and even the 3D desktop settings are working in advanced mode. BUT the system is just way too slow to react to the mouse and keyboard. I'm certain that the lack of memory has a lot to do with that although I was secretly hoping that the huge swap file would help to make a big perfomance difference. So here now my questions:

1. The swap file doesn't really appear to have made any difference at all. How come?
2. If I wanted to "downgrade" to Xubuntu, how would I accomplish this?
3. Would it be a better idea to just start over with an installation of Crunchbang instead?

I'm trying to get this system working for a relative who's never had a computer before. Whatever I end up with on this machine has to be as simple as possible to use while maintaining some semblence of decent perfomance. I'm sure before too long they'll want to enhance their desktop looks/theme as well so consideration needs to be given to that too. Your suggestions and comments would be appreciated. Again, Ubuntu Lucid runs just fine, although really really slow. Internet is no problem.

Ubuntu :: Swap Or Swap File On Flash Memory?

Aug 16, 2010

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?

Ubuntu Installation :: Swap File Onto New Extended HD?

Feb 1, 2010

I want to move my swap file onto a new extended hard drive.
Device Boot Start End Blocks Id System
/dev/sda1 * 1 1243 9984366 83 Linux
/dev/sda2 1244 1305 498015 5 Extended
/dev/sda5 1244 1305 497983+ 82 Linux swap / Solaris

I want to put a 2Gb swap file on sda2.
> dd if=/dev/sda2 of=/mnt/2Gb.swap bs=1M count=2048
0+1 records in
0+1 records out
1024 bytes (1.0 kB) copied, 0.000388458 s, 2.6 MB/s

Why is this only copying 1.0kB? Do I need to format the extended drive first? I have tried specifying the block size and count a number of different ways with the same results.

Debian Installation :: SSD - Garbage Collector And Swap Partition / File

Feb 27, 2015

After some years using OS X, I'm returning on Debian on my Macbook Pro in single boot.

I've bought a Samsung SSD (850 EVO 500Go) in order to replace the slow built-in HDD.

But I've earned about the need of repartition of writing operation on that kind of drives, and I'm concerned about swap partition.

I need swap (especially for Darktable, browsers and maybe Steam games), but I wonder if the usual swap partition (even with discard mount option) is really recommandable for SSD drives.

Actually, on Debian wiki and others, the usual recommandation is "if you have enough RAM, don't use swap or minimise swapiness to 1", but using of swap file is not mentioned.

Indeed, if I have only one "big" partition on the SSD drive and TRIM activated, the garbage collector (low level) built in chipet's SSD will optimize SSD life, but I don't know how the low level garbage collection works with multiple partition.

So there is my questions :

- Will SSD garbage collection will preserve the disc use even if I have a 2GB swap partition ?
- Will I'd use a swap file instead of swap partition (I don't really need to hibernate) ?

Ubuntu Installation :: Dual Boot Partitioning \ What File System Should Use For Windows Swap Partition

Sep 1, 2011

I am about to get a new laptop here soon and I was planning a dual boot like I have on my current laptop (Win7 and Ubuntu), but I have something special in mind. I looked around the forum to see if there was anything like what I had or if it was even possible but I didn't see anything quite like this.I was wondering if this was even possible, and if so, would anyone be able to tell me what filesystem I should use for my windows swap partition?

Ubuntu Installation :: How To Downgrade To 10.04

Oct 16, 2010

how is it possible to downgrade to the Ubuntu 10.04 from Ubuntu 10.10?

I have two reasons for doing it:

1. My internal microphone stopped working in new kernel (ThinkPad Egde 13')

2. New Ubuntu's look and feel is ugly.

Probably this problem may be solved with installing the theme, but it seems not to affect the font, which is the most terrible thing in new release's design. Is it possible to have the 10.04's look and feel here in 10.10?

Ubuntu Installation :: How To Downgrade To 10.10

Apr 29, 2011

When you get to the login screen at the bottom there is a box where you can select "Ubuntu Classic" and that will take you to a Gnome 2.3 desktop.I just updated to 11.04 which is so disappointing.It is like I am coming from multi-thread world back to single-thread world. Any in one workspace, you can only do one thing: either surfing internet or something else, but you cannot do both at the same time.On 10.10, we can do multiple things simultaneously and we can switch between each other easily. Now the good feature of 10.10 is completely discarded.

Ubuntu Installation :: How To Downgrade From 10.10 Back To 10.04

Oct 27, 2010

How to downgrade from 10.10 back to 10.04? I had 10.04 and was using this for a while and was very happy with this release. though recently I upgraded to 10.10. Since doing so, My screen flickers very annoyingly every 10 seconds or so. I've searched the forms best I could and it appears some other are having this problem and there really is no fix at this time, but to go back to 10.04 - so that is where I am at this moment.

Ubuntu Installation :: Downgrade Back From 10.04 LTS To 8.04 LTS?

Nov 5, 2010

I upgraded from ubuntu 8.04 to 10.04 LTS using the update manager and the result is that ubuntu boots into a black screen. Unfortunately I did not test 10.4 before with the Desktop CD, which I tried now, with the same result: black screen. So most likely a hardware screen card issue... which I did really not expect since 8.04 was running very well and the update was coming from the update mananger. Never change a running system. I assume my only chance is to re-install version 8.04 with the iso CD. But before doing so, is there any must-not to keep an eye on?

Ubuntu Installation :: Downgrade From 11.04 Alpha To 10.10?

Mar 12, 2011

how/if I can downgrade my dual-boot partition (win-7/11.04) to 10.10 without having to reformat the entire disk?

Can I use the same partition I installed the alpha 11.04 on to install 10.10 and save myself a lot of work?

Is it possible to simply reformat the Ubuntu Linux partition and re-install 10.10 there while preserving my Windows 7 installation?

Can I keep the newer GRUB boot loader for 11.04 (I like it better), or will I be forced to downgrade that as well?

I just tried the alpha, and I can't use it. It's still too green, so I want to go back to 10.10 the easiest way possible, so I'd need a little detail on the process of using the advanced partition features (if this is even possible).

Ubuntu Installation :: Tutorial - Downgrade To Firefox4 On 11.04

Jul 8, 2011

For compatibility reasons, a developer do not always need the newest software version that just poped up on the market.
In my case, right now, the WebDriver Test our Selenium Test framework doesn't work on Firefox5 that i automatically got thanks the Ubuntu Update manager. I had to search few hours on Internet and finally ask a more experimented college which told me about this solution:

first of all, uninstall firefox5:

Code:

sudo aptitude purge firefox

then, you can list the available software versions : sudo apt-cache policy <software_name>

Code:

msauvette@msauvette:~$ sudo apt-cache policy firefox
firefox:
Installed: (none)
Candidate: 4.0+nobinonly-0ubuntu3

Is there another repository that I need to add to have access to an older version?

Ubuntu Installation :: Home Folder Is Not Recognized After Downgrade

I downgraded from 11.10 to 10.10 via installation CD, because the 11.10 installation was lost beyond recovery.

The 10.10 installation works fine except one problem During the installation, I selected manual setup of Partitions and my home partition was not recognized as /home but only as ext4.

Fortunately I managed to recognize it, due to the size of the partition, so I prevented this partition from being formatted.Now, this partition is not my home partition, but just an ordinary partition, which I can access and where all my files are present.Anybody knows any magic trick, how I can make this partition my home partition?
