I now have Linux installed on my Google Pixel C tablet.

As the title of this posting suggests.

I used the Android app “UserLAnd“, which does not require root. The most recent versions of this app offer a VNC Server, which emulates an X-Server within the Linux system. And the implementation of VNC is ‘TightVNC’. Plus, the latest versions of this app offer a built-in VNC Viewer, that I find makes the most, out of the tiny icons that display on the high-res screen, as well as out of the fact that often, users will want to operate the GUI with their fingers, along with the physical keyboard that my Pixel C pairs with (:7) …

The setup of this Linux Guest System is much easier than my earlier experience was because the basic Linux distribution, the desktop manager, and certain apps can all be installed just by tapping on a few icons. And then, using the ‘sudo apt-get’ command-line, additional Debian packages can be installed.

There is an interesting side effect to this project: When I give the command:

$ cat /etc/debian_version

I obtain the result ‘10.0‘. This would mean that the Linux version which I’m getting, is the new Debian / Buster, which none of my PCs nor my Laptop are even running. However, the repositories that I’m subscribed to are labelled ‘stable’. The CPU is an ‘arm64′. And the desktop manager I chose was ‘LXDE’. I installed a full productivity suite, including LaTeX. But, I found that three Linux applications did not run:

  • LyX – The graphical, WYSIWYM LaTeX Editor (:2).
  • Synaptic – A GUI for apt-get that makes it particularly easy to browse package-repositories, before selecting which packages to install.
  • Latexdraw‘ (:1) (:6).

Everything else I tried seems to work, including “LibreOffice”, “GIMP”, “InkScape”, “Firefox ESR”. On my own, without the aid of simple GUI-buttons, I was also able to install and run “Texmaker”, “Dia”, “Xfig”, “OpenClipArt”, “Maxima” and “wxMaxima”, the Computer Algebra System and its Graphics Front-End. Getting that last item to work properly actually required that I install the package ‘fonts-jsmath’.

The Linux Guest System is currently taking up 5.37GB of my internal storage, and I finally also found out how to share files between the Guest System and the Host System. Within the Guest System, if on the Host System the root of the user folders is ‘/root/<sdcard>’, then this Host System root is mounted at ‘/host-rootfs/<sdcard>’ (within the Guest System). This means that I can open a path directly to this folder in the file-manager ‘PCManFM’, and bookmark it. (:3)

Just revived the computer named ‘Klexel’.

As it stands, I have several computers, all running Linux. And one such computer which I had blogged about before, is named ‘Klexel’. This is a 32-bit computer onto which I had installed a trial version of Kanotix, in which that group of programmers was testing something which would later become a de-facto distribution named ‘Steelfire’. By now, ‘Kanotix Steelfire’ is being superseded from Kanotix, by a newer version called ‘Kantoix Silverfire’. Steelfire was based on Debian / Stretch, while Silverfire is based on the newer Debian / Buster. But, I don’t have any Kanotix Silverfire computers installed yet.

Main Kanotix distributions are generally equipped with the latest version of KDE / Plasma as their Desktop Manager, but Kanotix also generally offers one alternative, such as LXDE. My computer named ‘Klexel’ had LXDE on it from the beginning.

There was a time when I was not even turning that computer on. But now I have done so again, and installed many software updates.

Plasma 5 Notifications In Wrong Locations

I use a version of Linux on the one of my computers named ‘Plato’, that has Debian / Stretch as its base, but which also has Plasma 5 as its desktop manager. This was a system which I created from a Kanotix Live DVD, from before Kanotix had an official Debian / Stretch release. According to that Live Disk, the desktop manager was LXDE !  LXDE stands for “Lightweight X Desktop Environment”, while Plasma 5 is the successor to KDE 4, and is a powerful, CPU-consuming desktop manager. In the meantime, Kanotix has created two official ‘Stretch’ releases, one with LXDE and one with Plasma 5, both named ‘Kanotix Steelfire’.

What I felt I needed to do with Plato, was to install Plasma 5 via the package manager, even though the Kanotix developers had not yet done so. This customized Plasma 5 environment has been running fine for some time.

But only recently, after my email client – Thunderbird – received an update to version 60.x, I did notice that some of my desktop notifications seemed a little odd. Instead of appearing as official Plasma / KDE notifications, they appeared either as stylized bubbles, or as more-boring drop-down lists from the center, of the top, of my screen. And so this can lead to some confusion, or to some doubt in whether the system is still stable. In fact, I’ve read some other complaints from the Web, of people who ran in to the same behavior exactly. What seemed to irk them as well as me most, was that although we can use our KDE / Plasma Notification settings to designate, where we want notifications to appear, these apparently rogue notifications seem to disregard this setting.
