2018 iMac with High Sierra sometimes boots with no cursor -- a fix

Posted 01-06-2019 at 07:09 PM by flshope
Updated 01-13-2019 at 07:43 PM by flshope

I purchased an iMac all-in-one machine in June 2018. An immediate problem I encountered was that the machine sometimes booted with no cursor. The mouse and keyboard are both wireless. The keyboard always worked, but the mouse was rendered useless whenever the machine booted with no cursor, which was intermittent. Turning the mouse off and on (after fully booting) generated a screen acknowledgment that the mouse status had changed but did not bring up the cursor. The voice assistant Siri was no help...

Upgrade of 7-year-old machine from Ubuntu 16.04.5 LTS to 18.04.1 LTS

Updated 09-06-2018 at 09:07 PM by flshope (clarification)

I recently upgraded my primary computer from Ubuntu 16.04.5 LTS to 18.04.1 LTS (hardware summary below). I have the machine set up for dual-booting with Ubuntu and Debian 9.5 from separate hard drives, each with its own Grub installation. My preferred window manager is Gnome Flashback although I had been using Unity for a while toward the end of 16.04.

As I have done in the past, I installed the 18.04 upgrade using the Update Manager (UM). The upgrade process went smoothly in terms...

15-year-old desktop kept alive with Debian 9 and Xfce (but not GNOME)

Posted 06-29-2018 at 12:25 PM by flshope

I have a 15-year-old Pogo Linux Altura desktop machine using an AMD Athlon(TM) XP 2400+ 2GHz processor. I call it Pogo2003. The machine has 1 GB of RAM and two 120 GB hard disks. Despite its age, the machine shows no indication of hardware deterioration. So it has become a bit of an obsession and hobby of mine to keep it running with a current operating system. It serves as one of two backups to my primary machine (Pogo2011), which is only seven years old.

Until recently, the machine...

Machine Description

I have a six year old desktop machine from Pogo Linux (my hostname: "Pogo2011"). The machine has been running Ubuntu since it was new and is now at 16.04.2 LTS. The machine has an AMD Athlon(tm) II X3 450 Processor, 64 bit, 8 GB RAM, and two 500 GB SATA hard disks. One drive contains the OS and the other, my own data files. This is my primary desktop, though I have a 14 year old desktop ("Pogo2003" running Debian 8.8) and a 9 year old HP laptop...

Brother HL-2140 B&W Laser Printer under Debian 9 only prints blank pages: a fix

Posted 07-04-2017 at 06:28 PM by flshope

I recently installed Debian 9.0 on my primary machine (Pogo2011). This installation is dual boot with Ubuntu 16.04 and each OS booting from a separate hard disk, each with its own Grub installation. The machine had Debian 8.8 previously. I decided to do the Debian 9 installation as a clean install (rather than as an upgrade) because the 8.8 was a bit messed up (let me not go into that here). The Debian 9 install was done from a netinst CD. It appeared to be a textbook-successful install. The post-install...
