Ubuntu 14.10 vs Kubuntu 14.10 vs Xubuntu 14.10 vs Lubuntu 14.10 vs Ubuntu GNOME 14.10: A Comparison

Honestly, I have used better Linux distros than Ubuntu. But, I don't deny that Canonical's Ubuntu took Linux to the masses. Five years ago when I started using Linux, I started with Ubuntu as well. Those days none of my friends knew about Linux and now almost everyone of my friends knows Ubuntu, if not any other Linux. And even in my blog, articles on Ubuntu gets 30% more hits than non-Ubuntu articles. And the request for this article came from quite a few readers of my blog. Here I won't compare a lot on the aesthetics bit as each distro is unique and it is good to have diversity. My primary focus will be on comparing performance and ease of use.

I reviewed each and every one of the official Utopic Unicorn releases separately. If interested you can visit individual reviews:

• Ubuntu 14.10 
• Kubuntu 14.10
• Xubuntu 14.10
• Lubuntu 14.10
• Ubuntu GNOME 14.10

Further, 64-bit versions of all the five distros were benchmarked using the exactly same machine over last 1.5 months. So, in this comparison I am comparing apples to apples.

Operating System (64 bit)	Ubuntu 14.10	Kubuntu 14.10	Xubuntu 14.10	Lubuntu 14.10	Ubuntu GNOME 14.10
Release Year	2014	2014	2014	2014	2014
Size of ISO (GB)	1.109	1.017	0.979	0.702	0.998

Installation

All 5 Ubuntu releases have similar installation steps though the installer may look marginally different in case of Kubuntu. The steps are pretty simple and should not take more than 10-30 minutes of your time depending upon your internet connection.

• Step 1: Choose language
• Step 2: Check if it meets the minimum requirement and manually check download updates while installing and install third party software. Installing third party software is critical to play multimedia files and watch online videos in YouTube. If you are not an expert in Linux, please check this.
• Step 3: Select where to install, choose your destination drive and format options. Hit enter once done.
• Step 4: Select geographical location - mostly picked automatically. Otherwise click on the graph to select.
• Step 5: Select Keyboard language and layout. In general it should be English (US) for most of the users.
• Step 6: Create user ID and password. Please remember what you are setting as if you forget, you may not be able to log in.
• Step 7: Click continue and wait till the distro installs.

Ubuntu has the most intuitive installation process and it works every time I have used. I guess it should not challenge even novice users.

Aesthetics

Each of the five distros are unique and look different from each other. Ubuntu 14.10 has Unity 7.3.1 desktop environment and has an unique look with a blank desktop and left hand side panel. Ubuntu's customization options are rather less than other four. Ubuntu Tweak tool comes really handy in this regard.

From Ubuntu 14.10 http://mylinuxexplore.blogspot.in

Kubuntu 14.10 should look familiar to Windows 7 users. I used both KDE 4.14.1 and KDE Plasma 5 in my review. Plasma 5 with flat icons looks simply stunning and should appeal to Windows 8 users. KDE 4.14 has countless themes and user customization options available across the internet. You can practically make it look whatever way you like it to be.

From Kubuntu 14.10 http://mylinuxexplore.blogspot.in

Both Xubuntu and Lubuntu are comparatively lightweight operating systems and they look visually less appealing than Ubuntu or Kubuntu. But, experienced users can tweak them appropriately to make them look better.

From Lubuntu 14.10 http://mylinuxexplore.blogspot.in

Ubuntu GNOME looks very refined and supports some customization option. I found a lot of aesthetically appealing themes across the internet for GNOME 3 which works with Ubuntu GNOME 14.10. Further, Tweak tool is there to tinker around with default settings and add GNOME extensions.

I would score or rank order the distros on aesthetics. I leave it to you to decide which one looks best to you.

Hardware Recognition

All of the Ubuntu distros recognize hardware impeccably without any issue. Screen resolution, sound, WIFI, LAN, touch pad, etc. worked perfectly without any issue for all the five distros. I was able to successfully install NVIDIA prime or bumblebee on each of them.

Ubuntu, Kubuntu and Ubuntu GNOME ship with full LibreOffice whereas the lightweight Xubuntu and Lubuntu ship with Abiword and Gnumeric. However, complete LibreOffice suite can be installed from Ubuntu repositories.

Image editors like GIMP is pre-installed only in Xubuntu. Lubuntu has mtPaint, a lightweight image editor with limited functionality. Similarly, startup disk creator, a software to create bootable live USBs, is missing in Xubuntu and Ubuntu GNOME while present in the other three.

Integrated settings manager is present in all, barring Lubuntu. So, if you are a Linux novice, Lubuntu may give you a hard time if everything doesn't work well from the beginning. Kubuntu, Ubuntu and Ubuntu GNOME has the best integrated settings managers followed by Xubuntu.

Anyway, these are minor differences that I am pointing out. Mostly the distros try to provide the common applications required for regular use and anything you need extra, can be downloaded from the Ubuntu Utopic repositories.

Each of these distros have a package manager with GUI like Ubuntu Software Center (Ubuntu, Xubuntu, Ubuntu GNOME), Lubuntu Software Center and Muon Discover (Kubuntu). They are easy to use and have good search options. Only Lubuntu has Synaptic Package Manager in addition. I like Synaptic as it works faster than other package managers.

Performance
Perhaps the most important section and the results you have been eagerly waiting for. I divide the section into three parts: Resource usage (RAM, CPU), Power Usage and Boot time.

Performance	Ubuntu 14.10	Kubuntu 14.10	Xubuntu 14.10	Lubuntu 14.10	Ubuntu GNOME 14.10
RAM Usage (MB)	599	547	350	246	515
CPU Usage	0-5%	0-5%	0-5%	0-5%	0-5%
Boot time (Seconds)	33	34	31	30	39
Power Usage (Watts)	12.06	12.31	11.67	10.21	11.21
Space Occupied (GB)	4.6	4.6	4.3	4	4.8

Resource Usage
As expected, Lubuntu is the least RAM hungry distro followed by Xubuntu. Lubuntu consumes about 250 MB RAM at steady state with no application except system monitor running. Under identical conditions and on the same laptop, Lubuntu consumes 30% lower RAM than Xubuntu, 52% lower RAM than Ubuntu GNOME, 55% lower RAM than Kubuntu and 59% lower RAM than Ubuntu 14.10.

From Ubuntu GNOME 14.10 http://mylinuxexplore.blogspot.in

Ubuntu GNOME is the third most efficient distro with a RAM consumption in low 500 MBs. Both Kubuntu 14.10 and Ubuntu 14.10 consume nearly 600 MB RAM under identical conditions and on the same machine.

Power Consumption
Even on power consumption, Lubuntu 14.10 tops the list for being the most efficient. Lubuntu consumes 9% less power than Ubuntu GNOME 14.10, 13% lower power than Xubuntu. Kubuntu is the most power hungry followed by Ubuntu.

From Ubuntu GNOME 14.10 http://mylinuxexplore.blogspot.in

Boot time
All of the Ubuntu distros boot pretty fast and within 30-40 seconds. There is not much to separate between the five of them but Lubuntu 14.10 boots the fastest.

From Ubuntu GNOME 14.10 http://mylinuxexplore.blogspot.in

Disk Space
All the distros occupy around 4-5 GB of space and nothing really there to separate between them.

Overall
So, in nutshell, I found Lubuntu 14.10 to be the best in performance among the Ubuntu distros. It offered me trouble free experience throughout my usage and I found it to be really stable. Anyone looking for a really really efficient distro and those with low powered machines can safely bet on Lubuntu 14.10

Based on my experience, I found Ubuntu GNOME to be the second best offering very decent performance with a very refined desktop environment. I thought Xubuntu would occupy this position but unfortunately, a bit of instability in the distro marred my experience. I would safely recommend Ubuntu GNOME 14.10 to users with modern laptop with or without touchscreen over the rest of the four distros.

As usual Kubuntu is the slowest of the lot and consumes the most power. You can expect the least battery life from Kubuntu. However, the desktop environment (specially the Plasma 5 upgrade) is mind blowing! Those with powerful modern machines and less usage of battery power can safely choose Kubuntu as it seemed to be the most exciting of the lot.

Finally, Ubuntu 14.10. I would recommend users to download and install Ubuntu 14.04.1 LTS with support till April 2019 rather than this almost similar distro. I didn't see much difference between the two and actually Ubuntu 14.04.1 performs a whole lot better on my laptop.

So, my ranking:
1. Lubuntu 14.10
2. Ubuntu GNOME 14.10
3. Kubuntu 14.10
4. Ubuntu 14.10
5. Xubuntu 14.10
