Luke's Ubuntu and Linux Hacks

After I upgraded my Linux Ubuntu computer to version 25.10 , I kept getting the message " Firmware available for KEK CA ". I searched Gemini AI for an explanation and, possibly, for a fix, and this was the answer I got: Click here for answer. So I opened the Terminal and typed in " sudo fwupdmgr update " (no quotes); (Gemini did not include "sudo" but you might have to include it to make things work correctly.)  After I ran the command in the Terminal I received the message: " WARNING: UEFI capsule updates not available or enabled in firmware setup See https://github.com/fwupd/fwupd/wiki/PluginFlag:capsules-unsupported for more information. Devices with the latest available firmware version:  • UEFI CA Devices with no available firmware updates:   • Fujitsu BIOS DB Certificate  • Fujitsu BIOS KEK Certificate  • DB  • KEK  • KEK CA  • MQ01ABD100  • Option ROM UEFI CA  • Phoenix Kek Example  • SBAT  • WD20SDRW-11VUU...

Some time in the past 3 years I started having problems with my dialog boxes being "attached" to their background applications in such a way that I could not move or resize the dialog box without dragging the background application along side it. That was a huge problem for me, as much of my work involved the need to see the work I was doing at the same time as having a dialog box open (I will spare you the details).  I searched every Linux forum I could to find a  solution. Not only did I not find a solution, it appeared that I might be the only person on the face of the earth with the problem. (...

The Issue I asked this question of Google Gemini 2.5 Pro Flash: "When I open Chrome browser in Ubuntu 25.04, I get the message "Can't Update Chrome," with an offer to reinstall Chrome. Is that message generated by Chrome or by Ubuntu?" The Answer (Click for the entire answer) (I found the entire answer to be soothing to my soul and my psyche (a) to know that this wasn't some phishing or spam that infected Chrome or my Linux machine; (b) to understand the problem and why it occurs (which makes me think that surely other Ubuntu users have the same problem)). What I Did (How I Fixed ...

For reasons you should not care about, recently I found myself needing to hook up my trusty, but well-worn and somewhat ancient HP Laser Jet 1020 to my Ubuntu Linux 25.04 machine. Several years ago this same printer was hooked up to another Linux machine, probably with Ubuntu 19.04 or thereabout. When I set out to connect to my current computer, I recalled that HP had some site where you could go to download drivers, and I recalled that the last time I installed this printer I used the terminal to download all sorts of supporting files. I also had a vague, somewhat repressed memory of what a pain in the bippu...

The issue "in Ubuntu, set the number and speed of strokes for space bar and backspace" was the subject of my Gemini search. In trying to fix some other problem, I was enticed into making changes in Settings, Accessibility. As a result, it seriously slowed down the time it takes to clear / erase text by using the Backspace key, or by holding down the Shift key and the Left key. It also, for some reason, decreased the amount of time between repetitive keystrokes, which means that each time I typed a word with two consecutive letters, a third and even a fourth instance of the letter was created.  Words...
