My Dell Optiplex 780 is blanccoed, how do I know whether I need a 32 or 64 bit ubuntu?

What is the difference between 32-bit and 64-bit Ubuntu? I've heard the 64-bit platform performs better and can detect more than 4GB of RAM. Also, while some apps haven't ported to 64-bit yet, ia32-libs lets a 64-bit machine run them.  If so, why not promote 64-bit over 32-bit?

I was trying to install Ubuntu 12.04 in VirtualBox 4.2.12r84980. I see    this kernel requires an x86-64 CPU, but only detects an i686 CPU, unable to boot   But I am using a 64 bit Windows 8, and trying same .iso for trying Ubuntu. Then what is the problem?

Why is there no 32 bit ISO for the new Ubuntu 18.04?

I have Ubuntu 14.04. I recently downloaded . The Viber .deb file has 64-bit architecture. I want to install it on my computer, but my computer only supports 32-bit.  The output of running lscpu is as follows:  Architecture: i686 CPU op-mode(s): 32-bit, 64-bit  Byte Order: Little Endian CPU(s): 2 On-line CPU(s) list: 0,1 Thread(s) per core: 1  Core(s) per socket: 2  Socket(s): 1  Vendor ID: GenuineIntel  CPU family: 6  Model: 23  Stepping: 10  CPU MHz: 2800.000  BogoMIPS: 5586.12  Virtualization: VT-x  L1d cache: 32K  L1i cache: 32K  L2 cache: 2048K

I am planning to rent a VPS service with following basic specification:   512mb of RAM 1 CPU 20gb HDD (4gb of it is swap) Ubuntu 10.10 server   I am able to choose between a 32 bit or 64 bit install of Ubuntu server as the operating system.   My question is would it be better to chose a 32 bit operating system since I will have only 512mb of RAM, rather than using a 64 bit operating system and dealing with the additional overheads?  edit:  I have installed Ubuntu server 10.10 32 bit and 64 bit on VirtualBox. After a minimalistic installation with only ssh server, the 32 bit installation consumes 63mb of RAM when first boot up and 64 bit consumes 85mb of RAM.  After installing and running  daemon, 32 bit consumes 99mb of RAM when first boot up and 64 bit consumes 128mb.

How shall I find out the frequency and type of my current RAM? My OS is Ubuntu 12.04.

Ok, I've always, for some reason, thought that my cpu had 32 bit registers... so I always installed the 32bit version of all OSs that I've used. Now though I ran a lscpu, and I get:  fer@fer-lap:~$ lscpu Arquitectura:          i686 CPU op-mode(s):        32-bit, 64-bit   Does this mean I can use 64 bit OSs?  Running these I get:  fer@fer-lap:~$ grep flags /proc/cpuinfo  flags       : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc arch_perfmon pebs bts aperfmperf pni dtes64 monitor ds_cpl est tm2 ssse3 cx16 xtpr pdcm lahf_lm dtherm   And I have read that the lm flag means long mode, which stands for 64 bit cpus. Also, as a last test, running lshw gives, for the cpu section:   *-cpu:0               descripción: CPU               producto: Intel(R) Core(TM)2 Duo CPU     T5800  @ 2.00GHz               fabricante: Intel Corp.               id físico: 4               información del bus: cpu@0               versión: 6.15.13               serie: 0000-06FD-0000-0000-0000-0000               ranura: U2E1               tamaño: 2GHz               capacidad: 4096MHz               anchura: 64 bits   It's in spanish and the last line stands for width (I guess register width). So... can I install the 64 bit of the OS? Will it be a big diference in performance? Because that's what I'm looking for (doesn't need to be a BIG difference)  Thanks in advance.

To check whether I am using 32bit or 64bit Ubuntu. I looked in  and found this answer uname -a. If it is shown as i386, it will be 32bit and amd64, it will be 64 bit, but I got this result:  Linux mukund-ThinkPad-Edge-E431 3.8.0-35-generic #50-Ubuntu SMP Tue Dec 3 01:25:33 UTC 2013 i686 i686 i686 GNU/Linux   What is this i686? Is it 32bit or 64bit - I think  it is 32bit, because all the Debian packages which I installed in it are of 32bit, so can anybody please give a detailed explanation.

I was told that computers with more than 2 gig's memory need a 64 bit operating system to utilize all RAM.  Is the 64bit Ubuntu download really JUST for AMD processors? I am asking because the disk image I downloaded says AMD64.  So will my new Intel 2.3Ghz Core i3 Dual Core processor work with 64 bit Ubuntu?  It runs the 64bit version of Windows without any qualm.

I need to use a large software package (Xojo) that requires the 32-bit architecture to run. Try as I might, I can't seem to install the 32-bit libraries on my 64-bit installation of 15.04.  I don't have a problem running a 32-bit version of Ubuntu (I'm only using this computer for Xojo) but the computer has 8GB of RAM and I'd like to be able to use it all. Is there a way to utilise all 8GB of RAM with a 32-bit Ubuntu install? Does Ubuntu do this out of the box?

I have an older HP netbook and am looking for a 32-bit version of Ubuntu 18.04 desktop. Can you advise if one is available?

My laptop diagnostic shows several pre-fails and has other issues so I am urgently shopping for a new laptop, my second using Ubuntu. I need a laptop with good graphics capabilities and have come across a couple with the Nvidia GeForce 840M graphics card. In other words, I do not have a problem now and am hoping to avoid one.  My research on Ask Ubuntu and elsewhere shows that there have been some bugs with Ubuntu 14.04 and Nvidia drivers (not just for the 840M driver) but that fixes were made or a least suggested. But I have seen nothing definitive, e.g. the Ubuntu Certification for laptops is barely starting with 14.04.  I am about to spend a 1000 dollars and would love a little more assurance before I proceed -- my understanding is that a Live CD cannot perform a full simulation. Are there easy-to-recognize concrete factors which make compatibility (more) predictable, such as specific models of computer and their processors?  I am a considering a  with an Intel i5 4200M  and an  with an Intel i7 4700HQ. Both use an Nvidia 840M graphics card.

I recently made the switch to Ubuntu. Everything on my laptop works fine except my hybrid graphics card. It is Intel graphics combined with Nvidia GeForce GT650M. I tried Bumblebee, but primusrun doesn't work (segmentation fault, core dumped) and optirun works with glxspheres64, but steam games look worse with optirun than with Intel graphics (e.g. Surgeon Simulator 2013 runs fine with Intel and hangs a lot with optirun)   I tried Nvidia Prime, but it gives me a black screen on startup after install, so I can't do anything and have to power off my PC with the power button. I also tried nvidia-prime 0.5 on Ubuntu 14.04, and then I get 'low-graphics mode' and I can't get to Unity.

Ubuntu can't be installed on my system because of what the title says. This is because support Intel HD Graphics 530 was only just added in Linux kernel 4.3 and all versions of Ubuntu only have kernel versions up to 4.2 as of 15.10. My computer's processor is the new Intel Skylake 6600K if you need to know, everything else is generic. It has a UEFI BIOS motherboard. Help?

I just installed ubuntu 13.04 x64 My resolution is 800x600 and there is no other option. I tried to install the nvidia driver 313 but still nothing. I tried doing this   still no luck, thank you

What's the best and quickest way to detect whether you're running a 32 or 64-bit version of Windows Server from the command line?  (Cygwin is installed)
