Snowlinux 3 E17 Crystal Review: Fast, very fast!

The world of preferred Linux window manager is dominated by Gnome, KDE, XFCE and LXDE primarily. About 90% of the new releases I see are based on either of the four desktops because of the extremely elegant graphical interfaces they offer. However, with changing priorities and a need to provide aesthetically pleasing visual effects, Linux world is also undergoing tremendous transformation, specially Gnome 3. Most of the today's highly sophisticated Linux distros no longer run well on low resource environment or support desktops less than 512 MB RAM.

However, there are some competing window managers who are trying to make a mark by proving ultra-lightweight desktop environments like Enlightenment, IceWM, JWM, Fluxbox, etc. Macpup, Puppy and Bodhi, I know, leverage these lightweight window managers to give very functional distros working on extremely low resource systems.

Having used and liked Macpup for quite sometime, I was eager to try Snowlinux 3 E17 with Enlightenment desktop once I read the release note on Distrowatch. Earlier, I reviewed Snowlinux 3 and was pretty impressed with it. I downloaded the 733 MB 32-bit ISO from the Snowlinux server and first did a live-boot followed by full installation. The system used was Asus K54C laptop with 2.2 GHz Intel 2nd Gen Ci3 processor and 2 GB DDR3 RAM.

Similar to other distros in the Crystal stable, E17 Crystal is also based on Debian Wheezy. Beta 2 installer of Wheezy got released this month only and is more or less the freezed version for the stable release to be announced in, I guess, sometime in Oct'12. Linux kernel used is the same as Snowlinux 3 Crystal Gnome, that is, 3.5.

The default desktop has a Mac crossed with KDE feel. However, I could use the settings to change profile to look like Gnome 2 or a typical Snowlinux with only the lower panel. Further, there is a mobile option for touch devices with a touch key pad. I started the mobile option but unfortunately couldn't find a way to go back to the other profiles. Ultimately, reinstalled the OS again as a solution!

Applications
Just like it's gnome counterpart, even here, the applications are carefully chosen considering the systems on which E17 is supposed to run. Most of them are lightweight and less taxing on the system, like, Abiword for Office. There is no point of having a relatively heavier LibreOffice suite and hence, the developers' decision to put Abiword is correct. However, I would have liked to see Gnumeric as well.
Firefox 14 is the primary browser. There is no by default flash support. Lightweight browsers like Dillo or Midori could have been given as an option but anyway, Firefox is miles ahead of all of them. Firefox 15 is already out and users can upgrade to 15. Thunderbird is the default email client with a bit torrent client completing the list. There is a menu entry for a "Web Browser" which I thought would be some lightweight browser provided in addition to Firefox, but it opens Firefox only. Possibly it is a lapse or meant to start the default browser, assuming users will install multiple browsers! Further, for some apps there are no icons! It doesn't look good and possibly the developers should take care to refine this distro further.

From Snowlinux 3 e17 Crystal
Audacious is the default music player and Gnome Media Player is for media. Multimedia codecs are there by default and hence, users can play movie or songs right after installation is complete. Few other applications are there like Geany for programming, leafpad, etc. Overall, it is not many but some essential softwares provided out-of-the-box. For rest of the apps like VLC, Chrome, Skype, Cheese, etc. and multimedia codecs or Flash plugin, there is Debain repository to download from!

From Snowlinux 3 e17 Crystal

One good thing is that all the settings are integrated to a common window, Settings Panel. I find this integration helpful as it reduces a lot of headache for new users.

From Snowlinux 3 e17 Crystal
The OS has two file managers, Thunar 1.2.3 and Enlightenment. I expected Thunar 1.4.0 here as it's been 4 months since it got released.

From Snowlinux 3 e17 Crystal
Anyway, both are fast and provide almost all necessary functionalities like drag and drop, cut-paste-copy, etc. And I tried moving a file from Thunar to Enlightenment by drag and drop and it worked! However, Thunar is definitely a more functional file manager, originally designed for XFCE.

Installation
Installation didn't take much time for me, maximum 15 minutes, with the internet switched off. I just had to choose language, keyboard language and location at which I intend to install it. Boot up was quick, within 10 seconds and I didn't face any trouble over any driver not working or internet not working. So, it was practically trouble free for me.  Post installation, Update manager notified me of a 10 MB update and things were up and running after that.

Repository
Snowlinux is 100% compatible to Debian repository and everyone knows how rich it is! Applications cna be downloaded via both Software Center and Synaptic Package Manager. I downloaded quite a few essential apps like VLC, Cheese, GIMP 2.8, adobe flash plugin, etc.. All of them worked without any issue, what-so-ever.

RAM and CPU Usage
Here, I was a bit disappointed initially. On the same machine, Snowlinux 3 with Gnome 2 consumed 125 MB RAM and 5-10% CPU. I expected E17 edition to consume significantly lower memory but it was around 130 MB with 2-5% CPU usage. But, when I tested RAM/CPU usage with Firefox, Abiword, Media player running, it was around 170 MB with 2-6% CPU usage. So, definitely this distro can run well even on systems with 256 MB RAM! And that is really encouraging.

Overall
Did I mention how incredibly fast and responsive this distro is? Yes, it is fast, real fast. Plus, my touchpad worked out-of-the-box with it. Given the kind of multi-tasking opportunity even on low resource systems. So, for those who are running a PIII or a PIV, instead of installing minimalistic distros, you can try out Snowlinux 3 e17! If it works for you, nothing like it! Barring few rough edges, it is a really secured distro with plenty of functional packages to offer and can put antiquated systems back to life and running. To add to it, Snowlinux 3 E17 is supported until February 2016 and is fully compatible to Debian repo. Further, for modern systems, if you need a Linux which is extremely fast, works with modern drivers and very functional offering a complete range of applications, you should try it out. I bet you won't be disappointed.

Knoppix 7.0.4 Review: Lightweight Linux on the go!

The tale of Linux as live CD or USB started all with Knoppix. First time Knoppix showed that you can have an OS which you need not install and can carry conveniently to anywhere you go! Other Linux distros soon followed the suit and possibly, Knoppix lost it's advantage somewhere down the line.

From Knoppix 7.0.4
I have heard a lot of Knoppix but never used it before last week. On the release note of Knoppix 7.0.4 came in Distrowatch, I was quick to download the 730 MB ISO. Definitely, the ISO size is significantly higher than similar distros like Puppy Linux or Slitaz but comparable to crunchbang, another lightweight minimalistic distro. Knoppix is a Debian based distro and has Linux kernel 3.4.9. So, it will be based on Debian testing, I guess.

The live boot up was really fast and I was greeted with a typical LXDE desktop. I used a 512 MB RAM Asus P4 old laptop to test Knoppix. Neither of the modern Ubuntu clans distros load on it. Lubuntu 12.04 loads but barely runs! I have Crunchbang installed there as my main OS.

To my surprise, Knoppix performed really fast on it and I could multi-task with Iceweasel (though I hate this Firefox derivative!), Synaptic package manager downloading updates, LibreOffice writer, and LibreOffice calc running! I saw the RAM consumption - 150 MB! CPU consumption of 1-6%! Even by low resource consuming Linux distros, I haven't such a thing!

From Knoppix 7.0.4
With only task manager running and nothing else, the default desktop loads with about 70 MB RAM. Of course, if you start playing flash videos, the story might not be as good! To test how Knoppix performs with flash video running, I installed flashplugin from Debian repository, using synaptic package manager. Post installation I tried out youtube videos and with a flash video playing, the RAM consumption was 180 MB! Now, that is pretty impressive!

From Knoppix 7.0.4
Like Puppy, Knoppix loads totally on RAM and even in low resource systems, performs really well. Plus, through Knoppix, users can download variety of applications from Debian repositories. Now, that is an advantage Knoppix has got over Puppy or Slitaz! Once loaded, it recognized my lan connection perfectly with input of IP configuration from my side. Wifi was also recognized properly, I faced no problems with sound or display.

Application-wise, it is quite rich with full LibreOffice suite, Iceweasel browser (you can download Firefox as well), Pidgin messenger, GIMP 2.8, Gnome MPlayer, among other things. File manager is PCManFM 1.0, the latest version. There is compiz given as well, and if your system supports, you can add some cool desktop effects. I played a bit with Re(-start) 3D desktop compiz to create the cube. But, I guess there's some compatibility issue of compiz with advanced Linux kernels and many times the screen simply went black while rotating the cube to finally come back after 5-10 seconds. Also, may be my low powered system is responsible for it not working properly!
From Knoppix 7.0.4

From Knoppix 7.0.4
Java is provided by default. Adobe flash plugin, as mentioned earlier, need to be downloaded. Further, you can download your favorite programs from Debian stable, testing and experimental repositories. Possibly that is one of the best Linux repo you can get!

From Knoppix 7.0.4
Now in live-boot one thing I noted is Knoppix never asked for any root password, not even for downloading programs. So, I decided to install it in my HD and check how good it performs when installed. Installation didn't take much time. I had to format and partition my HD and rest went really smooth. Finally, it installed GRUB and I was ready to go within 5 min.!

Post installation, it took 5 sec. flat to bootup and load the desktop. It was the same as live boot but I see 20% less RAM consumption once I installed it in HD. LXDE desktop with Htop or task manager running takes 65 MB, and Iceweasel with flash video in youtube running takes 160 MB! Of course, CPU usage is around 30-40%, mine is an old processor. But, even after installation, it didn't ask for an user ID creation or root password! However, there is an option in the menu Knoppix -> Set password for root, where I changed the root password. Still it never never asked me the changed password even for installing apps after a re-boot. Like Puppy, this may be a security concern.
From Knoppix 7.0.4

From Knoppix 7.0.4
In overall, I must say I am impressed with Knoppix. It is lighter than, say a Lubuntu and the installation process is easy. I tried with USB drives and I guess auto-mount is there and had no issues with it. It is definitely a distro worth recommending to anyone who is looking for a lightweight but complete Linux OS. It can run on a 128 MB RAM computer but 256 MB is recommended to enjoy flash videos and multi-task.

Snowlinux 3 Crystal Review: With LTS Linux Kernel and Gnome 2 desktop

True that Linux world is going through a rapid change. There are three types of Gnome based distros I see:

1. Distros which are using Gnome 3 as such
2. Distros which have Gnome 3 but have their own modification as well, like Unity in Ubuntu, Cinnamon in Linux Mint, etc.
3. Distros which still prefer Gnome 2 or Gnome 2 derivative like Linux Mint Mate, Scientific Linux.

Snowlinux 3 Crystal too falls in the third category - a Gnome 2 desktop with Linux 3 kernel. Due to drastic changes happening to Gnome 3 & Unity,  Snowlinux has kept Gnome 2 but with the updated Long Term Support (LTS) Linux kernel 3.2.0 LTS.

From Snowlinux 3 Crystal
I downloaded the 860MB ISO from Snowlinux website. It is based on Debian stable and it shows from the desktop interface, which is similar to Debian Squeeze, as you see below when I change the default wallpaper to Debian.
From Snowlinux 3 Crystal
The boot up screen is also refined to reflect Snowlinux and supports live booting. Most of the system settings including webcam was detected, except touchpad. I couldn't get my touchpad working in Snowlinux crystal.

Applications
I felt all the applications (out-of-the box) are very carefully chosen to give users a complete distro. There is no over-abundance of apps, nor there is a shortage as well. You get a LibreOffice suite, Firefox 14, Thunderbird 14, bit-torrent client, a video player (gnome media player, Rhythmbox, Basero, Empathy etc. Most of desired apps are there and you can download apps like VLC, Chrome, Pidgin, GIMP, etc. from the debian repository. Adobe flash support is not by default but you can get flash player from the repository.

CPU & RAM Usage
I was pretty impressed with the low resource consumption of this distro. With only System Monitor running, the RAM consumption was 123-125 MB and CPU usage of 1-10%, which is much lower than comparable Debian 6 derivatives, including Ubuntu 11.04.

From Snowlinux 3 Crystal
Overall
Snowlinux is really good and if you need a OS which is cutting edge but has the low resource consumption of the olden days, possibly this is the Linux distro you should try out. I am impressed, to be honest.
