Just installed Ubuntu 15. Completely deleted Ubuntu 14. However, running a 3GHz with 1 gigabyte of RAM, I'd think Ubuntu would 'fly'. Ubuntu 15 is much slower than Ubuntu 14 was and I wouldn't begin to know why. Any advice?

For a given hardware configuration, how do I find out if Ubuntu will run on it? What considerations should I take into account when choosing an Ubuntu version and  such as:    with a lighter desktop than the usual Gnome and Unity  with the even lighter LXDE desktop   Obviously Ubuntu does not run on some processor architectures. So how do I go about choosing the right version and derivate. How can I find out the minmal system requirements?

I wish to remove Ubuntu and I'm not quite sure how. I know it has something to do with partitions. I have 3 partitions. 1. OS [683 GB]  2. Recovery [14 GB] 3. Ubuntu 12.04 LTS (E:)  I know it says Ubuntu but when I installed Ubuntu I think I put 14 gigabytes for it so I think its the recovery one but I'm not sure. I could have sworn I put more than 700 megabytes for it.  I have googled this and I can't seem to find an answer. Any help would be nice.

I've got a HP probook 4515s, AMD Sempron SI-42 (2,1 Ghz), ATI Radeon HD 3200, only 1GB ram.  I'm installing Ubuntu 12.04 with a CD right now, and it seems to take about 20 minutes since.  And its also my first time I use ubuntu and I wanted to know how to set up wlan ( a friend told me it doesnt work on my pc) And maybe a link to a site telling my which things I need to install and what I should know and stuff.

My PC has 8 Gb of ram. Is there any way to make ubuntu use most of it? I mean rarely drop caches and keep once opened programms in ram longer, preload apps on boot, etc.

So I've a feeling this is a very noob question but...   Is the only difference between flavors of Ubuntu the graphical interfaces and installed packages? Will they all be equally capable of running 3rd party programs, i.e. Chrome, Dropbox, Android Studio, Steam, etc?  I've a new PC on which I live tested Ubuntu 16.04 and it runs fine. However, I don't care for Unity and if Xubuntu/Lubuntu are lighter weight does that just mean I'm just sacrificing visuals for performance? Ubuntu 16.04 is the commercial release(?) so is its specific set-up just a little more reliable? Don't quite get Linux yet,there's so much choice I'm confused!

An  has an .  The memory is . It has only about 1000 MHz DRAM frequency:      Could anyone provide a clue on why the RAM speed is so low?  Am I missing some fundamental understanding of the speed numbers?

My computer has 1GB ram and a very end low graphics card, but I don't know how much power it has.  Unity is very slow on my computer, and I saw that there are many desktop environments which are much lighter and faster, even for a slow computer.  So, what's the lightest desktop environment?

I just want to know, what is the difference between ubuntu Minimal, Desktop &amp; Server Editions? How they differ? is it by performance? If yes which one is recommended for a normal user and which one is recommended for a advanced user ?

I'm going to install 64 bit 14.04 on a new machine with something like 1 to maybe 128GB RAM and even more RAM later. How much space should I allocate to the swap partition?   And especially: WHY those recommendations for these numbers?    (None of the existing answers  and  explain any of the why and are a bit dated if we look at 1GB or RAM and up)

What are your tips for improving overall system performance on ubuntu? Inspired by this  I realized that some default settings may be rather conservative on Ubuntu and that it's possible to tweak it with little or no risk if you wish to make it faster.  This is not meant to be application specific (e.g. make firefox load pages faster), but system wide.  Preferably 1 tip per answer, with enough detail for people to implement it.  A couple of mine would be:   Install  (via Software Center or sudo apt-get install preload); Change  value - "which controls the degree to which the kernel prefers to swap when it tries to free memory";   What are yours?  PS: Since this is not intended to have a unique answer but rather, several useful tips, I'm making this community wiki out-of-the-box.

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.

Can someone please tell me the differences between Ubuntu and Linux Mint ?   I thought they were almost the same thing until I downloaded Ubuntu 13.10 versions of softwares for my Linux mint 16 system, and half of them didn't work. (I did that as those are the links I got when I searched for Linux mint versions)

I'm running a Windows 10 64-bit host OS on a Dell XPS 9560 with 8GB of RAM.  I've installed Ubuntu 16.04 for programming purposes using VM Workstation, and currently allocated 1GB RAM for the Ubuntu 16.04 guest OS. From what I noticed now the VM's performance is a little slow from time to time, especially when starting an app (Like CLion IDE or Firefox for example).   I need a performance boost, so is there a way to increase the RAM size in the existing Ubuntu 16.04 guest OS, rather than having to install a whole new guest OS in VMware Workstation and allocate more RAM during the installation process?

I'm considering to upgrade my PC to Ubuntu v17.10, but I'm afraid because there's a BIOS issue has been confirmed for several different lines of Lenovo laptops also the reports of it affecting a few Acer, Toshiba and Dell laptops.  Should I upgrade or not? Also I can't download the Latest Ubuntu 17.10 ISO, the official website download link is currently discouraged.

I'm brand new to Linux. I just installed Ubuntu as a dual boot system on my HP Pavilion laptop.  Where should I start? I've tried to play around with Terminal over the last hour or so, but I'm probably not helping myself out. Any suggestions are welcome!

I have been using Ubuntu for a long time now, this is what happened when I use:  Systemd: It performs really bad using systemd: it uses 95% of the CPU all the time and the PC gets really hot. Also it takes a really long time to boot (about 1.5 min, and sometimes it does not boot at all as it has a black screen at boot.)  Upstart: When I tried the upstart options at boot, it performs as expected, booted in seconds, and it was awesome as it should be.  Laptop:   AMD A8 Radeon SSD   Questions:   Why does upstart perform better than systemd? How can I debug systemd? Should I switch to upstart? If yes, how do I do it?

Are there any drawbacks to installing Ubuntu 13.10 (and soon 14.04) in Legacy BIOS instead of UEFI?  I have installed 13.10 64bit in Legacy by mistake and was just wondering if it would hurt anything to simply leave it there as is?  EDIT  Everything seems to be running just fine in Legacy and all my drivers work.
