  • Getting Linux working with the Lenovo Yoga 13

    This worked for me with the Elementary OS, a distribution of Linux based on Ubuntu, which in turn is based on Debian, but you may have luck getting this to work in other distributions as well.

  • Setting up WiFi on Raspberry Pi

    This isn’t only for Raspbian running on a Raspberry Pi, as far as I know you can use it on most flavors of GNU/Linux if you want to set up WiFi using only the terminal. This also assumes that you already have appropriate drivers installed. I have tested this with this wireless adapter and the…

  • Running a script at startup in Ubuntu Server

  • Mounting a USB drive in Ubuntu Server

    Source Manually Mounting Sometimes devices don’t automount, in which case you should try to manually mount it. First, you must know what device we are dealing with and what filesystem it is formatted with. Most flash drives are FAT16 or FAT32 and most external hard disks are NTFS. sudo fdisk -l Find your device in…

  • Installing a GUI on Ubuntu Server

    Since the Ubuntu Server edition doesn’t by default install a window manager, you may want to install one yourself (if you need one). This is how to do so. Either use the tasksel command, or just directly type in (only one) of the following commands: sudo apt-get install ubuntu-desktop sudo apt-get install lubuntu-desktop sudo apt-get…
