ARM – Original Hikey Updated and Fixed – with Gotchas..

Adventures With Linux ™ Posted on September 9, 2019 by RGSeptember 9, 2019

After successfully updating and re-configuring the Odroid C2 to use Fedora uefi/grub2 to boot, I decided to try to do the same to the even-older Hikey SOC. This already booted using fastboot with an older version of grub, with manual configuration, but I wanted to use the standard (Fedora) boot process. I had read that there was … Continue reading →

New Install – Dual-Boot, Serial Console, Intel Ethernet Issues – Fixed..

Adventures With Linux ™ Posted on February 18, 2019 by RGFebruary 18, 2019

Setting up an old HP8000 desktop small-form-factor system as a crash-and-burn test system, with dual-boot Fedora 29 and Windows 7, on separate drives. First slight gotcha with the Fedora install: The installation utility shows the two disks, the first of which has Windows 7 (sda) and the second – additional – was for the Fedora Linux install … Continue reading →

Fedora – F28 Upgrade on ARM64 – Fix for GPG Errors..

Adventures With Linux ™ Posted on July 6, 2018 by RGJuly 6, 2018

When doing a # dnf system-upgrade reboot on an ARM64 system you may encounter a stream of GPG errors, followed by reboot, without upgrade. To fix this, simply import the F28 GPG key in advance, as done for Rawhide: # rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-28-primary After this, the system-upgrade should proceed correctly..

SCSI – Adding and Removing Disk, Without Reboot..

Adventures With Linux ™ Posted on December 23, 2017 by RGDecember 23, 2017

Many aeons ago, I used to have SCSI disks on my ancient Linux systems, but the only SCSI device I attached nowadays was the LTO Tape drive, for full system backups, very occasionally..   Now, I have the HP RX2600 IA64 system, with nothing but U320 SCSI LVD disks, and needed to find a way of attaching one … Continue reading →

IA64 – An Exercise in Nostalgia..

Adventures With Linux ™ Posted on November 21, 2017 by RGNovember 21, 2017

Ever since I spent some considerable time promoting HP’s IA64 Linux systems, way back in the early-2000’s, I have always wanted one for myself, and I recently managed to acquire an RX2600 1U server for a very reasonable price, and beef it up with some inexpensive parts from eBay.. The spec – at the moment – is … Continue reading →

Fedora – 26-27 DNF Upgrade Woes, and a Workaround..

Adventures With Linux ™ Posted on November 15, 2017 by RGNovember 25, 2017

After upgrading four Fedora systems (x86_64) from release 26 to 27, using # dnf system-upgrade download –refresh –releasever=27 –allowerasing –nogpgcheck –best -y, two of these worked OK, but two failed – with a sudden reboot, back to F26 – and no (apparent) error displayed, after # dnf system-upgrade reboot had rebooted the system, and the upgrade process … Continue reading →

Hardware – UEFI Bios for Linux ‘Chromebook’

Adventures With Linux ™ Posted on August 11, 2017 by RGAugust 11, 2017

The original ‘SeaBios’ BIOS on my Acer c720p was a little clunky, so I decided to make the plunge and update it to a ‘proper’ Linux-friendly BIOS..    There is a known/good one available, but it is UEFI-only, so will involve changing the filesystem/partition layout on an existing system.. Disk /dev/sda: 119.2 GiB, 128035676160 bytes, 250069680 sectors … Continue reading →

Hardware – Replacing the System Disk..

Adventures With Linux ™ Posted on June 2, 2016 by RGJune 2, 2016

My ‘system disk’ (/dev/sda) started to show bad sectors, recently, and so I decided to replace it.    The disk was around 8 years old, and had been in almost-continuous use.. I have not had to do this for some considerable time, and I think the last time was in the late-90s, and using LILO!  (No convoluted grub2 … Continue reading →

Fedora – Installing a Working ZoneMinder..

Adventures With Linux ™ Posted on December 24, 2015 by RGDecember 24, 2015

Installed ZoneMinder ( https://zoneminder.com ) for some IP and WiFi cameras, and the first thing to remember is to not use the Fedora version!    This is due to the lack of ffmpeg and vlc support in that version, which makes the software somewhat less than useful.. Fortunately, there is good Fedora support, with a fully-functional version – … Continue reading →

ARM – ARM64 Developments…

Adventures With Linux ™ Posted on June 25, 2015 by RGJune 26, 2015

Just took delivery of a Qualcomm Dragonboard 410c (https://developer.qualcomm.com/hardware/dragonboard-410c) : The unit is based on a ‘standard’ (96Boards) design, with a few quirks..   The device uses fastboot rather than U-Boot, and in this respect is more like flashing a custom ROM on a cellphone!    It even has on-board volume up/down buttons.. There is no Ethernet built-in, so … Continue reading →
