  • Linux RAID-1 [8]: Setting up the replacement array

    As I mentioned last time I have bought the 2 TB disks so that I can have a RAID-1 array in the main computer that is big enough to hold all of my stuff, meaning the second computer (and by extension, its screens and desk) will be effectively redundant. So here I am essentially repeating…

  • Virtualisation and Qgis

    UPDATE: The below comment does not make a lot of sense as I have since used Virtualbox VMs very extensively to run Qgis and edit maps. Right now I don’t have need to do this, but in the past it has certainly been a major part of the Qgis work that I have done. (Unfortunately…

  • The Linux systemd debacle

    If you are reasonably familiar with the Linux ecosystem you will be aware that there has been a big rift over a process called “systemd”. This particular process, or processes, are concerned with Linux system and session management. The issue has been for many that systemd steps beyond its role of being the “init” process…

  • Enable hibernation in Xubuntu

    Hibernation is a somewhat controversial subject in the Linux desktop community. It is considered to be difficult to implement and to have the potential to cause a lot of problems. I have used hibernation wherever possible on all my Linux desktops but it is not always straightforward. Older hardware may not support it, and even…

  • Installing Chrome on Ubuntu

    What’s interesting about Chrome is the different icons. On Mint computers and Lubuntus the icon has been square, while on Xubuntu we are back to the old round icon. This may be because of the different installation method I have used. In general it is better to use a package supplied with your distro rather…

  • Xubuntu vs Lubuntu

    Well of course after playing with Xubuntu at home it didn’t take much to have it installed on my work computer, a very old Wolfdale with a Celeron CPU and 4 GB of RAM. A very slow computer for its age, and also relatively old. Not sure exactly but I would guess around 6 years.…

  • Xubuntu vs Mint

    Today I decided I needed something other than Mint on one of my systems. I chose to do this because Mint has had security issues that led to their website being hacked and giving out malware, and their forum database passwords stolen. Which brings down the whole reputation of their project, unfortunately. There were only…

  • Linux Kiosk computer with Chrome Browser [3]

    So having built our image and got it going pretty much as we please, the next thing you will want is to be able to clone from one computer to another. The default Linux install can be a single partition for the OS. and a swap partition. Since the OS is all in one partition,…

  • Linux Kiosk computer with Chrome Browser [2]

    So my steps followed are: Install Ubuntu Server 14.04.5 from a bootable pen drive Set my username to user with a password Enabled automatic updates Install OpenSSH server in the tasksel at the end Reboot Log or SSH into the system (latter from another system is preferred since you can copy and paste instructions from…
