Solaar is software for more than just pairing wireless keyboards and mice Back on April 8th, 2025 I wrote about Using Logitech unifying devices with Linux in which I discussed how to use Solaar under Linux Mint, or Xubuntu, to pair Logitech unifying wireless devices. My goal with that article was just to provide simple instructions for people looking to pair their Logitech wireless unifying devices, but it turns our Solaar has other functions depending on the device. ...

I tried AI on my Lenovo ThinkPad T430s under Xubuntu Linux and it did something shocking! Yes, the heading above makes this seem like zoo of bad artificial intelligence videos on Youtube, but I was actually shocked at what happened when I tried to install Ollama on my ThinkPad T430s running Xubuntu Linux 24.04.2. Entertain me for a second and let me briefly explain why I was surprised: I’ve installed Ollama a bunch of times on hardware several years newer than my laptop. Ollama will run if you don’t have a modern graphics card (which sounds a bit strange since it’s mostly text based, but having a decent, modern Nvidia graphics card can really boost Ollama’s performance). ...

Logitech unifying, but needs configuration Logitech’s unifying system is nice for a few reasons: Any device with the Logitech unifying symbol should work with a unifying dongle. Up to 6 devices can attach to one unifying dongle. There are plenty of Logitech devices that are part of the unifying ecosystem. If you buy a new Logitech wireless keyboard direct from a retailer, chances are you can just plug the dongle into your computer, turn on your wireless keyboard, and work. But if you buy Logitech devices used, and/or they don’t come with the unifying dongle, a little work might be needed to get the device paired with the dongle. ...

Don’t physically remove a USB key without unmounting or ejecting it first I have destroyed my fair share of USB keys in the past by prematurely removing the key before it was safe to do so. I remember being particularly irked when my $70CDN 1GB Kingston flash drive stopped working. I think at the time I swore I’d never buy Kingston crap again, but I’m not so sure it was ever Kingston’s fault (to be fair, USB keys were fairly new on the market back then). Like a lot of people, I assumed you could just save a document, or copy your files over, and then pull the USB drive out. Maybe this was just a bad habit I picked up from my days of removing floppy disks (they never got corrupted either)? ...

Debian package over flatpak, but get it from Steam Moving from Xubuntu to Linux Mint XFCE was not as seemless as I’d hoped it would be. The last time I gave Linux Mint serious consideration was over 13 years ago when the Computer Recycling Project at The Working Centre was looking for a replacement for Ubuntu 10.04 (the next version would include the Unity desktop which wouldn’t run on a lot of our laptops at the time). ...

It lives, it dies! Our new TrueNAS server is up, and all the hardware is working, but not without some hiccups on the way. After taking a lot longer to build than expect, I was so happy the other evening when I posted about the successful Power On Self Test (POST), and the new RAM (32GB) being properly detected. Exhausted at the end of the day I left the drives disconnected and the video card out. ...

Most of the hardware is assembled The past few weeks have been extremely busy, so I knew last night would probably be the only time I would get this week to work on the NAS. I’m glad I started building the NAS last night as it took much longer than anticipated. I finally finished the build at 10pm last night (and it’s still not quite complete). Fig 1. I used an Intel Core i3-7100 CPU for lower power consumption ...

Past Isopropyl is a great way to clean up a lot of plastic, but I found that while it’s helpful for removing grime, caked on stickers (Goo Gone), and other crud, it doesn’t always leave a nice finish. A few years back a volunteer at the Computer Recycling Project mentioned interning at a small computer store where they used Mr. Clean Magic Erasers to clean-up the top of ThinkPads. True to what he said, Mr. Clean Magic Erasers do seem to be a pretty good job on the top of ThinkPads. ...

Moving more to a low-power solution Several months back I replaced the motherboard in the KODI media centre PC that sits in our living room. For many years our media centre has been rocking a Gigabyte motherboard with a second generation Core i7-2600 CPU. The Core i7-2600 came out in Q4 of 2010, making it almost 14 years old at the time I’m writing this. Still, it’s not a bad CPU. For several years it was the system I was compressing our movie collection on as the A8-5600K 4 core APU that was in my workstation (at the time) had about half the performance of the i7-2600. But about six months ago I replaced the CPU and motherboard with a still old, but more modern solution, a MSI motherboard and an Intel Core i3-7100. ...

Migrating the KODI entertainment system On May 5th I mentioned that we’re Running out of space on our media center. In the comments of that post I followed up outlining a plan to buy another 8TB drive (for a total of 3 x 8TB drives) in order to do a RAID Z1 (for 16TB of space). But in order to do that I would need to reformat the drives, which means I also needed a plan to back up our media center data. I hinted at that solution in the comments too: 4 x 3TB drives in a RAID Z1 – which would give me 9TB of space (1 x 3TB is the spare), just enough to back up all the data. ...
