Background Archaeological findings have revealed that prehistoric humans buried their forefathers under the floor of their huts. Fast forward to 2018, yours truly decided to continue running the (ancient) Fedora 12 as a chroot when migrating to Linux Mint 19. That’s an eight years difference. While a lot of Linux users are happy to just [...]
Introduction These are my somewhat messy jots while setting up an APC Smart UPS 750 (SMT750I) with a Linux Mint 19 machine, for a clean shutdown on power failure. Failures and mistakes shown as well. Even though I had issues with receiving a broken UPS at first, and waiting two months for a replacement (ridiculous [...]
In short On an embedded ARM-based Lubuntu 16.04, I had LXDE’s logoff dialog window offering suspend as an option, and when that was chosen, the system got itself into some nasty state with network and keyboard off. The serial console was still active, and yet, I was better off without it. It turned out that [...]
As systemd seems to be here to stay (or at least I hope so), this is a post of random notes to self that I jot down as I explore it. It will probably grow with time, and become a mixture of basic issues and rather advanced stuff. Useful references man systemd.service and man systemd.unit [...]
Introduction Having installed Linux Mint 18.1 (kernel 4.4.0-53) with overlayroot on a Gigabyte Brix BACE-3160 (see other notes on this here and here) for my living room media center, I had an issue with bringing up the computer every now and then. Namely, I had a blank screen with mouse pointer only, 100% CPU on [...]
Introduction These are my notes as I made Pulseaudio work on an ARM v7-based Embedded Lubuntu 16.04, which doesn’t support Pulseaudio otherwise. The goal: On a mini-distribution based upon Lubuntu, for use of others, make Pulseaudio work even though the Lubuntu desktop won’t start it. In fact, it’s supposed to run even without any X [...]
The problem Having A HD-901T2 DVB-T2 stick on a Linux Mint 18.1 running a 4.4.0-53-generic kernel, Tvheadend started painfully slow. It took more than a minute before the web interface was available. And here’s why: Mar 11 10:22:35 tv systemd[1]: Starting tvheadend.service… Mar 11 10:22:35 tv tvheadend[6019]: * Starting Tvheadend tvheadend Mar 11 10:22:35 tv [...]
Introduction I use USB flash sticks for backing up my system periodically by creating an image of the filesystem, and raw-writing it directly to e.g. /dev/sdd1. It’s just a matter of time before I wipe my hard disk by selecting the wrong /dev/something. Or just some other USB stick that happened to be plugged in. [...]
