Ubuntu :: Change From 32 To 64-bit With Minimum Hassle?
Jul 13, 2010
I have a 32-bit Ubuntu installation that for technical reasons needs to be 64-bit even though it has under 4 gigs of ram. I don't want to spend loads of time upgrading it, and almost everything is from the repository. So what I am hoping is that I will be able to find a way to "save" the programs I have installed and then automatically reinstall them when I install the 64-bit OS, install my (2) non-repository programs, and then simply reload the old home directory. Would that work, and how would I do it?

Background: So i am running ubuntu 10.04 on a amd computer, and this is the second time i have run into this problem. last time i was playing around with os's, trying to get around some annoyances, and i did a reinstall and it worked just fine, but since i have my computer the way i want it and i really don't want to go through the hassle of a reinstall.problem: when i boot up my computer i get a no grldr. exact print out:Try (hd0,0) Fat16: No GRLDR
Try (hd0,1): invalid or null
Try (hd0,2): invalid or null
Try (hd0,3): invalid or null
Try (hd1,0): EXT2: _
I have already tried once to reinstall grub, but i rebooted without unmounting the hd, though i don't think thats the problem, but since that first attempt, i have been unable to boot into live CD mode.

I would like to upgrade my linux distro, since I'm using Karmic Koala and it is no longer supported anymore. However, upgrading via the updater always breaks my system, so I want to do a clean install. However, I have a LOT of programs installed in this machine, including a good number of games. Otherwise I think most of my data is neatly confined to my home folder, which I can easily transfer via external hard drive.
How do I get all my programs over, however? Like my PDF printer, for example, or all my games, or Inkscape, or Skype, or any number of things that I have installed. Especially WICD. I can never get my wireless internet to work without WICD. I will make a list of my programs beforehand, just in case something goes wrong, but is there any kind of less painful and time-consuming way to do this than going back and installing every program all over again from scratch?

I currently dual boot windows XP Pro with Ubuntu 9.10. I made a mistake last night playing with gparted and lost my E drive, which had all of my music, games and movies plus is where my Ubuntu install was. I then ended up reformatting the drive with windows and reinstalling Ubuntu 9.10.My question is how can I put my windows files on my E drive without going through the hassle of reinstalling windows.
I have a 20g IDE drive where my windows install is, windows and Ubuntu both tell me this drive is failing, (I have used it for booting since 2002, so I am not that concerned with it), another 40g IDE drive for more storage and a 160g SATA drive where Ubuntu is again installed. I want the SATA drive to be my main boot drive now, so how can I clone my windows boot to the other drive. I tried gparted but could not figure it out. I have gparted burnt to cd, booted with it and just don't understand how to use it.Also, if I clone this boot drive to the SATA drive, do I need to change jumper settings on my 40g to master when I take out the 20g drive.20g master and 40g slave on first IDE channel and 2 CD devices on second IDE channel and SATA drive on first SATA connection. I read somewhere that it is better to keep the cd devices on another channel than the disk drives.

All on All Hallo(w)s Evening [HallowE'en] To who ever it may concern Dear Sir or Madam I am a relative newbie to computing having only started just two years ago. Up until today I have been using Windows Vista, but having come across the refreshing open source, creative commons and free software foundations that are much closer to my heart's way of thinking I decided to download and install Ubuntu as a prerequisite to switching completely away from paid for operating systems and software.
In order to do this I firstly purchased a new 1Gb hard drive and installed it alongside my factory installed 250Gb hard drive with the windows factory image etc on it. I then partitioned the new drive with 30Gb for Ubuntu, another 300Gb for any future backups (Yes I know it's a lot) from my separate Windows Vista OS 250Gb hard drive, which left 600Gb spare.
I got up early today a Sunday morning at 0500hrs to ensure I had plenty of download speed etc and that all would be done and dusted by the time I needed to be available today for family and community social commitments etc However nothing has worked out in anyway like I would have expected it to or in anyway like Ubuntu's descriptions project, and I am typing this letter nearly 7 hours later and I have still not got Ubuntu properly installed as a dual boot system alongside my windows vista. In fact I am very surprised at the somewhat illogical and careless approach that the web pages take in explaining how to download and install Ubuntu.
Firstly I arrive at the webpage : [URL]... To be greeted with an introduction and a red download button to the right.
I click on this and end up on page: [URl]... To be greeted by another red download button that is at least six times larger than the previous one and because it is in exactly the same place on this page as the previous one was on the previous page my mouse is already hovering over it and my brain just wants to click it and start using Ubuntu.
I quickly read the instructions: Click the big orange button to download the latest version of Ubuntu. You will need to create a CD or USB stick to install Ubuntu
And then I click to download and save/burn the download straight to a CD, which as you may well already realize is "Goodbye CD" because as I have since learned all I was doing was burning an exact copy of an ISO file to the CD that cannot be used for installing or booting from.
After I finally give up trying to get the ISO file to install ubuntu some 30-40 minutes later it's already 7am because it also took 40 minutes to download the file. Anyway I go back to the download page and read the instructions again including the little paragraphs that are underneath the huge red download button.
Originally my thoughts had been "These are obviously not that important because they are "below" the download button otherwise if they were of importance these instructions would have been placed above the HUGE Red download button along with any warnings like---
Before you download Ubuntu please check the following: A. Is this an installation to a PC with ubuntu already installed --- please click here

What is the minimum amount of processes that can be run and still keeping stable? I have what looks like over 100 processes running and my computer is lagging pretty bad. Attached is an output of
Code:
ps -A
And it comes and goes with the cpu usage. cpu1 will run at like 9 or 10 percent idle while cpu2 will run at 100 percent all the time. I am not sure whats going on. But id hate to have to start from scratch again begins I just got it set up the way i want it. And the network activity keeps having spikes when I am not online. I've scanned with multiple port scanners and nothing seems out of the norm.

I've been trying to install a minimal Ubuntu using mini.iso and have a couple of questions to you, wise heads gives me gnome without all "unnecessary" applications, but it also gives me things like evolution and a couple of others which I don't need/want. Is there a way to install the bare minimum of gnome, but without any of these applications?

I am looking to compile a kernel for my system which is a home built machine. This machine is stable and has not had any hardware changes in the past 2 years. I am trying to figure out exactly what modules and options to include in my custom kernel. Is there a way to see what modules are actually in use on my system and build a custom kernel based on that?

Dell eStudio 1737, has good maximum volume, but when I turn down the volume to a little more than 1/2 way, it is already very low. All other volume controls are already set to maximum. What I would like to do is fix the volume control so that the volume can be set across the entire range of the Alsa mixer control.

After working for about 15 years on MS Windows, I have decided to to change over to Linux. I have a current netbook with 1 GB RAM. The only work I would be doing on the netbook are:
1) Surfing Internet using Firefox browser.
I would avoid saving anything on my disk while browsing. If I need to open files, videos, then I would be opening them directly in the browser while I am connected to the internet.
2) I would be writing code in Java using Java Standard Edition (not the enterprise one).
Those Java programs may need to use the network, graphics, sound- actually the programs will need to use any available Java API/Package/methods available in the Sun distribution of Java.
Now, For the above to jobs, I want to install the bare minimum, smallest linux on my netbook. I mus mention taht I do not want any Linux package/program/library that will not be required for the above two jobs. To rephrase this, I want to have only those linux components that are absolutely necessary for the above two jobs (Surifng the internet with full power on Firefox, and developing Java programs which may use _any_ functionality that is provided by the Sun distribution of Java Standard Edition.

I want to create several virtual machines based on a minimal (no GUI) Ubuntu installation. I'm using VirtualBox (on Windows 7), the VMs are being created with 256MB RAM and using the Ubuntu Minimal CD Image [URL]. Because I want 4-5 of these virtual machines I want to use minimal disk space for storage too, which means restricting the virtual hard disk size for each. My first attempt was to limit it to 300MB, but when I got to the partitioning section of the installer it would not allow me to do automatic partitioning and forced me to do manual partitioning, it did moan about the size of the disk.
So I started again with a 1GB virtual hard disk, this time the installer was quite happy to do the automatic partitioning. My question is how small can I make my virtual hard disk without having to do manual partitioning? I don't have a problem with doing the partitioning manually but for easiness I just want to do it automatically and find it strange the acceptable size isn't mentioned anywhere (that I could find).

My Notebook CPU has variable speeds from 600MHz to 1.6GHz but since I upgraded to F13 it has not budged from 600MHz.I have already installed the gnome CPU speed widget and even if I set it to "performance" or "1.6GHz" it stays resolutely on 600MHz
The only indication that I can see that there is something odd is the output of acpitool tells me the min/max cpu speeds are 600MHz/600MHz. I don't know enough about the guts of Linux to know if acpitool is defective or if it's just repeating what it was told by something lower down.I will post some hopefully useful listings of some commands run under Fedora 13 and then the same commands on the same box with an F12 live USB.
Code:
Fedora 13
$ acpitool -c
CPU type : Intel(R) Pentium(R) M processor 1.60GHz

So short-term needing a replacement for the various tools MS traps you into to make it easy to work with SQL Server.
I'm going to be using postgreSQL, and I'm wondering what's a good strategy as far as a GUI front-end.
1. No building from source. Don't have the time.
2. Keeps package dependencies to a minimum.
3. Won't require me to use KDE. My dev machine is too old to use KDE productively.

I recently installed openSUSE 11.4 64Bit on my desktop computer and it is running like a breeze! I have an Intel Dual Core 2.5 and 2GB of RAM and a NVIDIA 8400GS 256MB display card. I just want to know if 2GB of system RAM would be sufficient to run a Windows XP VirtualBox with 768MB of RAM assigned to it? PS - openSUSE is still the best of the best!

What is the minimum CPU or processor required for a Debian stable installation with no GUI, desktop environment, or window manager? I can find specs for all minimum hardware capabilities except for the processor on a system with no desktop GUI. (Debian Stable GNU/Linux Installation Guide 3.4 Meeting Minimum Hardware Requirements) section 2.1.2: CPU, Main Boards, and Video Support and Linux Hardware Compatibility Section 4.1—Intel make it seem like any i386 CPU is good enough.

I have a very powerful I7 Intel processor. On this computer I want to simply run an instance of Apache Tomcat (dedicated server) running a java application with a bunch of things like mail server, servlet container, jasper, etc. Some versions of linux have too many features that I do not need. I do not want the clutter of features I will never use. What is the bare bone version of linux distrib? would that be debian?
These two distributions seem to be popular elsewhere on the internet:
CentOS 5 (64-bit)
Ubuntu Linux 8.04 LTS Hardy Heron (64 bit)
