How to Resolve Slow Boot Times in Ubuntu 16.04

I’ve recently upgraded my machine from Ubuntu 14.04.4 to Ubuntu 16.04.1, but while my computer used to boot in about 40 seconds, after the upgrade boot times increased considerably to 2 to 3 minutes. The first easy check was to look at dmesg:

There’s a bit 87 seconds gap between checking for the floppy, and VirtualBox drivers loading. So there’s definitely an issue here, but the log does not exactly give a clear queue. I’ve read you could use systemd-analyze to find which process(es) may be slowing down your computer at boot time:

Two processes are taking close to 8 seconds, but those 16 seconds still do not explain why it takes 2 minutes more to boot…Eventually, I realized systemd-analyze has a few more tricks up its sleeves:

The first command shows there’s no problem with the kernel itself, and something is slow in user space. The […]

Improve YouTube Video Playback on Low Power Intel mini PCs by Disabling VP9 Support in Chrome or Firefox

I’ve been reviewing several Intel Bay Trail, Cherry Trail, and Braswell mini PCs in the last year or so, and I always end up recommending Microsoft Edge browser over Firefox or Chrome for people wanting to watch YouTube videos, as the last two browsers always drop many frames with the video stuttering regularly. However I noticed that while Edge is playing  MP4/AVC (H.264) video, the other two browser would normally stream WebM/VP9 videos, and it could be the cause of the problem as H.264 can be hardware accelerated, but VP9 not, and the low power processor might not quite powerful enough to handle 1080p VP9 video decoding smoothly. So I investigated the issues with Vorke V1 mini PC powered by an Intel Celeron J3160 processor (6W TDP) with the three browsers by first checking enabled codecs in YouTube HTML5 page. Microsoft Edge has both VP8 and VP9 disabled When I […]

MINIX NGC-1 Review and Benchmarks with Windows 10 Home

MINIX NGC-1 mini PC is powered by an Intel Celeron N3150 quad core “Braswell” processor with 4GB RAM and a 128GB M.2SSD, and pre-loaded with Windows 10 Home. While the product aims to provide a convenient alternative to Intel NUC kits, as everything is pre-assembled and pre-installed, I’ll also compare the experience to Bay Trail and Cherry Trail mini PCs such as MeLE PCG03 or Tronsmart Ara X5. I’ve already provided NGC-1 specifications and some pictures, so today, I’ll test the capabilities of the device, and run some benchmarks in the review. MINIX NGC-1 Setup Once you’ve connected a USB keyboard and mouse, and the power supply, you are ready to start. Press the power button, the blue power will lit on the front of the device, and you’ll hear a beep and the very first time system will boot to Windows 10 setup screen where you’ll be asked to […]

Review of Light Biz OS Operating System for Desktop Use (Writing a Blog Post)

This is take 2 of using an Android mini PC as a desktop PC, as I’m currently writing this post from GeekBox TV box with Rockchip’s Light Biz OS, an operating systems based on Android 5.1 with some optimizations for desktop use. I’ve already installed various productivity apps such as Gimp and Microsoft Excel, and at first this was a problem sinc Light Biz OS “internal storage” partition was too small to install some programs, so I had to resize the “userdata” partition to 6GB to make it usable. I normally blog with Firefox in Ubuntu 14.04, so right now, I’m writing with Firefox for Android, and not WordPress Android app, which would have been another option. One of the first challenge was to create links, and I could copy links with a long click providing access to copy tools in Firefox, and copy the links with Ctrl+V in Firefox. […]

MeLE PCG03 mini PC Review and Benchmarks with Windows 8.1 with Bing

MeLE PCG03 is an Intel Atom Z3735F mini PC with 2GB RAM, and 32GB eMMC. I’ve already posted some pictures of the device and board, and since Windows 8.1 with Bing NTE (with proper license) is installed, I’ll first test the device with Microsoft OS as a reference, before trying Ubuntu or/and Android. MeLE PCG03 Setup The computer comes only with a power adapter, so you’ll need to find an HDMI or/and VGA cable for your display(s), and a USB keyboard and mouse to get started. Optionally, you’ll also want an Ethernet cable, and since storage is limited an extra storage device be it a USB hard drive, flash drive, or SD card. Once all is connected you can press the power button on the left side to boot the device. The boot normally takes about 20 seconds, but the first time, you’ll go through the usual Windows 8.1 setup […]

Mozilla Netcast is ChromeCast-like Device Powered by Firefox OS

According to Gigaom, Mozilla has been working on an HDMI TV dongle that might be codenamed Netcast with ChromeCast like video streaming and screen mirroring functionalities, and that runs Firefox OS with an open bootloader. There aren’t any hardware details available for the device, but we more or less know how it will work. As you are using your Firefox browser or another Firefox OS, you can simply click a “Casting button” to watch YouTube videos, mirror the screen or so on. I also understand it will be compatible with ChromeCast apps. Gigaom got hold of an engineering sample and gave it a try run Firefox browser in Android (Nexus 7), and playing a YouTube video on the TV using Netcast. It’s also working with Google Music, Plex, but some other apps are not working just yet. Mozilla’s media casting device has not been officially announced yet, so we don’t […]

Mozilla Releases Firefox for Android 14.0 with Improved UI and Performance

Mozilla announced Firefox for Android 14.0 on their blog yesterday. They stressed 3 key improvements: Much better performance The foundation claims they improved Firefox for Android performance in several areas, and users should notice significant  performance improvements such as faster startups,  smaller page load times, smoother panning & zooming and better overall Web app performance. Sunspider benchmark results are said to shows that Firefox for Android is much faster than the stock browser, but they did not provide numbers or comparison with other browsers. Instead, they developed Eideticker, a new benchmark, measuring Web experience, and they optimized Firefox for Android to it. And “Oh Surprise!”, they beat all other major Android browsers (Chrome, Opera and Dolphin) in their own benchmark. This benchmark shows that Firefox is over three times as fast as the stock browser, and nearly twice as fast as Chrome for Android on a Galaxy Nexus phone running […]

B2G (Boot to Gecko) Video Demo at MWC 2012

B2G (Boot to Gecko) is an open source HTML5-based operating system targeting mobile devices by the Mozilla Foundation. This OS runs on top of Linux and uses Firefox as the web browser. You can get further details on my previous post “Mozilla Boot to Gecko (B2G) OS Is Coming to Your Smartphone“. As previously announced, Mozilla showcased B2G on a Samsung Galaxy S2 at Mobile World Congress 2012. Every apps are written in HTML5 including the camera application that uses HTML5 Media Capture and Canvas for real-time effects. Engadget was there and shot the video demo below. If you have a Samsung Galaxy S2, you can build and try it on your device. This is experimental, so there is always the risk of bricking your phone. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to […]
