Hace unos días tuve un problema con mi Kubuntu 10.04 y la conexión de red. Cuando fui por apagar el PC, en lugar de apagarlo le dí a hibernar por error y cuando fui otra vez a encenderlo no tenia conexión de red disponible. Mirando en el icono que informa respecto a la conexión de red tenia un único mensaje que decía: Gestión de Redes Desactivada. Por tanto que yo intentara de buscar la forma de activar el gestor de redes, no encontraba nada y ninguna opción disponible. Después de varios intentos tuve que ponerme a buscar en la Web con mi portátil para ver si encontraba la forma de solucionar el problema. Afortunadamente encontré que el problema surge en cuanto se apague el PC de forma instantánea o como en mi caso por hibernar, por esos motivos parece que NetworkManager no borra el archivo de estado y cuando se vuelve a reiniciar el PC se genera este error. Para solucionar el problema hay que escribir una serie de comandos en el Terminal para borrar e archivo y volver a reactivar el Gestor de Redes. Os añado las líneas de comandos porque puedo garantizar que es una solución realmente efectiva:
sudo service network-manager stop
sudo rm NetworkManager.state
sudo service network-manager start
This week in our Linux Page (in Spanish) , we added a brief "manual" about installing Easy Peasy as secondary OS, on an eee pc 900. Before, we tried the installation of eeebuntu but the installation failed because the Install feature is not able to recognize the SDHC card. First of all you have to create a live USB with Easy Peasy using Unetbootin . Then you have to change the bootup BIOS on your PC. In this way, eee pc will boot up Easy Peasy directly. Once running, Easy Peasy will automatically run the "Install it" feature. Easy Peasy was the only OS which was able to read the SDHC and to offer the opportunity to install it directly on the card. You will need about 30-40 minutes to complete the installation. After that it is better to restart the system. Then, we suggest to update Easy Peasy using "Update Manager"; in fact you will discover more than 140 updates ready to be installed. Unfortunately, after updating the OS our Easy Peasy does not recognize the camera and we hope to be able to add some more information about possible solutions during the next days. Last but not least, we also suggest to deselect Ubiquity from the boot up using Preferences – Sessions – Startup Programs and you will not be annoyed by the Install feature each time you boot up your eee pc. Enjoy!
This week in our Linux Page (in Spanish) we have tested VirtualBox: a multiplatform virtual machine for x86 machines which allows you to test an OS from a simple .iso image. VirtualBox is easy to install and, just following the instructions contained in its interactive menus, you can setup your virtual OS in few minutes. We strongly recommend to be careful when you decide the quantity of RAM for your virtual OS. It is better to well balance it with the total RAM of your PC. When configuring the virtual HD for your OS it is better to select the “Dynamically Expanding Image” option. By doing this, your virtual OS will use all the hard disk it needs when in use. Last but not least, VirtualBox has a specific virtual USB controller which allows you to connect any USB devices to your virtual machines without installing specific drivers. Strongly recommended for all that people who like to test new OS without formatting their HD each time!
This week, in our Linux Page we have posted an effective review about GP2X: the Linux challenger against the proprietary PSP. We personally think that this new open source gaming device developed by a Korean company. The GP2X is very easy to use and in a long term perspective, it has many interesting possibilities (multimedia, MP3, etc..) if compared with PSP. When purchased with its cradle, it can easily be connected to any USB devices (as keyboards, external Hd, etc..). Moreover the open source platform can potentially offer nver ending solutions for new applications or games. At the moment the games available for this platform are not so many as the games for the PSP but we believe that in six-eight months the number of games will dramatically increase. Last but not least, the new GP2X-F200 has a crystal bright touch screen with functions. Recommended as reliable open source alternative to PSP!
This week, in our Linux Page (in Spanish) we have posted a brief but complete review about Krusader: one of the best file manager for KDE. As we all know, in the next Ubuntu 7.10 we will find the new Dolphin beyond to the traditional Konqueror (the KDE file manager and universal viewer) but we would like to prefer to keep your attention on this twin panel file manager. The complete list of Krusader’s features is so long that we prefer to underline just the main ones. In fact, two of the most interesting features are the remote connection manager and the special function for synchronizing directories which are very simple to use. Moreover the possibility of creating a customized menu gets Krusader very user friendly. Recommended!
Today, in our Linux Page (in Spanish) we have posted a brief but effective review about Hardinfo: the best system and OS profiler we have never found for Linux. Hardinfo is a very useful program specifically created to deeply scan your hardware and create reports in HTML or in plain text formats. We suggest to use this software before upgrading your pc or when you suspect something is wrong with your hardware. Moreover, Hardinfo let you to easily benchmark your pc performance with just a click. Last but not least, you can download the source code or, if you prefer the autopackage file (suggested) which will automatically install the program in your computer.
Today, in our Linux page we post a review about BUM a powerful, graphic Boot-up Manager for Ubuntu. Using this light software you can modify and decide what programs run at startup. BUM is a very useful tool, precious especially when you notice that your Ubuntu boot is becoming slower than in the past. Initializing the Boot-up Manager is very simple and fast: recommended for the Linux beginners (like us)!
Super Grub is a very practical and useful free bootable cd which can be very useful when you need to solve boot problems in Linux, Windows and other OS Independent. In our Linux page, Frank wrote a descriptive post about the many features you can find (and effectively use) in this terrific bootable cd. Super Grub is very light (just 1.45 MB of cdrom .iso), supports seven different languages and can be downloaded also in its floppy disk version.
