Linux Mint 18.3 Beta

 The Linux Mint team has announced the availability of a new development snapshot for Linux Mint. The new testing snapshot, Linux Mint 18.3 Beta, features several overhauled applications. The software manager and backup utilities in particular have been given a new look. Linux Mint now makes it easier to install third-party software, such as Google Earth and Steam, and Flatpak packages can be installed through the software manager. The new beta also features operating system snapshots using Timeshift. "Linux Mint 18.3 features Timeshift, a tool dedicated to system snapshots. Timeshift is the perfect companion to the Linux Mint Backup Tool. It doesn't save your personal data, it saves everything else. Thanks to Timeshift you can create backups of the operating system itself. You deleted system files by mistake? You can recover them. You upgraded to a newer release and something isn't working well anymore? You can go back in time." Further information can be found in the project's release announcements for the Cinnamon and MATE editions.

Install Linux Kernel 3.6.7 on Ubuntu

If you want to easily and quickly install the new kernel on your Ubuntu (12.10/12.04/11.10 the recommended versions), my advice is to rely script found below. That’s all you have to do! Open a terminal and type:

cd / tmp wget
http://dl.dropbox.com/u/47950494/upubuntu.com/linux -kernel-3.6.7-O linux-kernel-3.6.7
chmod x + linux-kernel-3.6.7
sudo sh linux-kernel-3.6.7


Now reboot the system and verify that the version is actually 3.6.6 using the command:

uname-r

As usual, in case you want to remove the new kernel, just follow this guide .

WARNING : If you have any problems (like black screen) and you have an Nvidia card, open a terminal emergency (beating Keyboard ALT + CTRL + F1 , or F2 … up to F8) and type the following commands:

cd / usr/src/linux-headers-3.6.7-030607/arch/x86/include
sudo cp -v generated / asm / unistd *. / asm

Of course, the path to you might be a little different (if, for example, you have a 64, the x86 bit from the previous command could become x86_64).

NB: after installing the new kernel, the possibility exists that some drivers (eg. video and wireless) stop working . It’s all about uninstalling and then reinstalling before rebooting the system (you may find yourself unable to use the graphical interface or the wireless network) or using an old kernel .
