Partial decommissioning of Gandalf



After a few months of continuous use of Linux Mint – mainly for simple browsing during workday lunchtimes and weekdays –  the headline of the project remains that wholesale migration from Windows to Linux is not functionally possible, for the reasons cited therein.  In this instance, the short story is no Microsoft Excel, no Foxit PDF browser for Windows, no on-the-fly VPN client.

Consequently, there is no further development use of Gandalf.  Gandalf has other issues as well: even in last days as a Windows machine, the hard drive had developed a nasty habit of intensive operation, wasting time and resources on misadventure not commanded by the user.  The habit has returned to Gandalf as a Linux machine, meaning that the user needs to sit around for up to fifteen minutes from time-to-time while Gandalf faffs around for no good reason.  There could be an underlying hardware issue of the hard disk.

Two apps give rise to the symptoms in Linux: rm and timeshift.  Timeshift is easy to resolve: just uninstall it.  But rm is fundamental to the operating system; difficult to see how rm could be usefully removed.

Rather than re-install Linux on Gandalf, Gandalf had the following applied:
  • Deletion of non-admin user account;
  • Uninstallation of FoxIT PDF Reader for Linux;
  • Uninstallation of Bleachbit;
  • Uninstallation of VeraCrypt;
  • Uninstallation of grive2;
  • Installation of secure-delete;
  • Running of sfill -lvz /.


With no user data to sync, Legolas uninstalled FreeFileSync.

This leaves Gandalf as a useable machine for a really patient user for light browsing only.

Google-drive-ocamlfuse remains on Gandalf.  A future session would need to create a new non-admin user account in which to run google-drive-ocamlfuse.

Gandalf thus reverts to a nearly-identical functional build as new laptop Sibelius, running Linux Mint 19.

Scanning & OCRring to PDF: Simple Scan, gimagereader and gscan2pdf v NAPS2 for Windows

The project is to build a Linux Mint machine to have the identical functionality and ergonomics as the existing Windows 10 machine. This stage relates to scanning paper documents to PDF and digitising the scanned text via optical character recognition. Environment & required functionality The scan-and-OCR function needs to run on the following machines: The Linux Mint Xfce 18.3 laptop " Gandalf "; A Linux Mint Xfce 18.3 virtual machine " Gimli "; The Windows 10 laptop " Legolas ". In any modern office - whether at home or at work - some transactional documents and documents from public authorities still arrive by snail-mail. This requires the ability to scan all documents, optionally with the digitisation of scanned text (typically via optical character recognition). The hardware is an old HP OfficeJet Pro 276dw, connected to the LAN instead of directly to a workstation. Alternatives There are two strategies: To use the software pr...

Adjusting screen brightness

The machine on which Linux Mint is installed an old Acer Aspire 5732Z (" Gandalf ") It has buttons to adjust the brightness of the screen's backlight.  When the user uses these buttons, Linux Mint correctly presented a fading-popup box (a slider bar) to denote relative brightness.  But Linux Mint did not actually adjust the brightness of the screen. It seems to be a known issue in the Linux Mint forums  and solved in multiple  stages by the Easy Tips Project . I followed the instructions on Easy Tips section 5.2  in Gandalf's admin account, then re-booted, then logged in using the user account, and the brightness adjustment function worked correctly. Easy Tips asks the user to discover the relevant property of the machine, then creates a file that contains a script of parameters that other programs in Linux Mint understand. This method worked for Gandalf, because Gandalf has an integrated Intel chipset. Useful commands at the Terminal ALT+T (or th...

FreeFileSync: data synchronisation over the local area network

The project is to build a Linux Mint machine to have the identical functionality and ergonomics as the existing Windows 10 machine. This stage relates to data synchronisation over the local area network ( now that, at last, a useful network connection has been established !) Environment & required functionality The network should be a local network - to share files and folders - between the following machines: The Linux Mint Xfce 18.3 laptop " Gandalf "; The Windows 10 laptop " Legolas ". The network is a local area network from a domestic router, the usual 192.168.x.x thing. Alternatives Peer-to-peer networking (file sharing, simple two-way server-and-client relationship) is the most efficient way for bulk data transfers, so if the network doesn’t work, then the test has failed. One alternative is already successfully tested and in use: Google Drive (via Backup & Sync for Windows and grive2 for Linux Mint) .  However, this is limited to th...
