If you often test Ubuntu using Live USB and Live CD you probably meet situation where you have a bunch a Live USB/CD lying around without remembering with Ubuntu version is on which USB/CD.
Here is a quick tip to find Ubuntu version of Live USB/CD without booting it that might be useful in this case.
Here is my first of post of a long series of quick tip for Linux! Hope you will enjoy them 🙂
It is always be useful to be able to get information of connected Wifi network using command line. This quite simple command does not require installation of tiers package and will give you helpful information such as bssid, ssid, security mode, IP address, IPv6 address, and more.

Update 8/11/2015 : 15.10 Installation guide is live!
Update 2/11/2015 : Ubuntu 15.10 is out and includes a lot of new features (kernel 4.3 🙂 ). Some bugs have been corrected, some new bug have appeared. I am compiling my experience and I will soon publish a new guide on how to install and make Ubuntu 15.10 run smoothly on the Dell XPS 13. See you soon!
Update 14/10/2015 : I missed it but the fix for the kernel panic on resume as been released on 11/10/2015 . No need to add lp14115880 PPA anymore. A simple system update will fix the issue. The guide has been updated in consequence.
Update 30/09/2015 : Barton George published a way to use the touchpad in PS2 mode using the new libinput. I tried it. After an hard time to configure it properly, I did not noticed any improvement so I went back to the default touchpad in I2C mode. That is the reason I won’t add this to the guide. If you want to use it regardless. You can follow this guide (witch is the same than Barton’s guide but better explained in my opinion). Please leave a feedback on your experience!
Update 10/09/2015 : Barton George explained on his blog that the XPS 13 Developer Edition has been sold out in Europe (not yet in US) and won’t be produced again because Dell is working on a new model (witch will come out “sooner that 9 month“).
It’s been a little more than one month since I published my first guide “Installing Ubuntu 15.04 on the Dell XPS 13 9343 (2015) : A complete guide“. I got a lot of comments and feedbacks. I was not expecting this and I’m glad I helped !
Since the last guide, a lot of thing changed. First of all the Dell XPS 13 Developer Edition was pulled from the market. The Sputnik Team wanted to fix the major issues before continuing to sell them (wise decision :)).
As of now (September 2015) the XPS 13 Developer Edition is back on the market (
not in every country for some reasons) and a lot of important issues have been fixed.
Canonical, the Sputnik Team and the community did a great job. The process to install Ubuntu on the Dell XPS 13 is now easier ; that’s why I decided to write a simpler and updated guide taking into account all the new fixes and feedback I received :
Installing Ubuntu 15.04 on the Dell XPS 13 9343 (2015) : A complete guide !
I see a lot of people asking for tips to optimize battery life on Ubuntu. Indeed I noticed that XPS 13 battery life was curiously not as good as under Windows 10.
Here are few tips that will considerably optimize battery life on Ubuntu.
Those tips have been tested on a Dell XPS 13 9343 (2015) but will work all the same on most laptop.
After I received my XPS 13 (QHD+ dsiplay) I noticed that, by default, Ubuntu and a lot of applications does not support HiDPI screens properly (yet). Everything just look horribly small…
Example : Spotify currently does not support HiDPI displays
HiDPI (High Dots Per Inch) displays are screens with a high resolution (3 200 x 1 800 for example). 4k, 5k, ‘Retina’ or QHD monitors are HiDPI displays.
Reducing resolution back to 1920×1080 is not a proper solution. The best way to meet “comfortable” environment is to scale the user interface.
I compiled here a list of the current major tweaks and setting available for optimizing Ubuntu interface scaling for HiDPI displays.
