Ubuntu 22.04.1 LTS (RTheren)


  • The first point release of Ubuntu 22.04 LTS is now available to download.
  • Ubuntu 22.04.1 LTS combines all of the bug fixes, app updates, performance tweaks, and security patches rolled out to the “Jammy Jellyfish” since its April debut.
  • Including:
    • The snap-packaged version of Firefox should start a little faster.
    • Updated NVIDIA graphics drivers.
    • Latest GNOME Shell 42 point release.
    • Also this big change:  Ubuntu 22.04.1 LTS will default to Wayland on hybrid systems with NVIDIA graphics drivers but default to Xorg for non-hybrid systems with NVIDIA graphics.
  • This is only a point release of the OS, and if you are already running “Jammy Jellyfish” you will automatically get 22.04.1 when you next run a full update.
  • And as usual Ubuntu makes new installation images for each point release, so if you go to the downloads page, you will get a shiny new 22.04.1 image.
  • Also, if you are running 20.04 “Focal Fossa,” or the previous short-term release 21.10 “Impish Indri,” then you can expect to receive 22.04 update notifications any time now.
  • Point releases usually include anything new and some would say they are the one to wait on. 
  • Not everything goes smoothly between major versions and the job of point release is to tidy up the rough edges. 
  • No need to upgrade since this will come in as regular updates. 

Galago Pro


  • The fine folks at System76, the makers of awesome computers and laptops powered by Linux, have a new version of their Galago Pro slim and light laptop available.
  • The updated Galago Pro specs are:
    • 14″ 1080P Matte Display
    • 12th Gen Intel Core i5 or i7
    • Intel® Iris® Xe Graphics
    • Up to 64 GB of memory
    • System76 Open Firmware
    • Pop!_OS 22.04 LTS or Ubuntu 22.04 LTS
    • Gigabit Ethernet, WiFi 6, Bluetooth 5
  • I configured a Galago Pro with 16GB of RAM, 500GB NVMe drive for $1,127.00.
  • I am in the market for a light powerful laptop to travel and go to Linux conferences with, and this one is at the top of my list!
  • I would hold off on 12 gen Intel + Linux for a while longer. 
  • If you have a 12th Gen you should be running kernel 5.18+ for the thread director. 
  • That said, you get a System 76 for the support and other niceties like open firmware. 
  • Matte screen. 
  • $1,552.00 for one I would begrudgingly carry around. 
  • There is also a flash sale on the 11th gen. 
  • System76, I went looking for Threadripper Pros and came up empty. 

Linux 6.0



  • This release was created to avoid the confusion of releases in the 20s, like 5,20.
  • Torvalds says that “6.0 looks to be another fairly sizable release.”
  • Most of the updates are improvements to the GPU, networking and sound.
  • And the Rusty bits are coming soon. 
  • Yeah, I know we missed out on having kernel 5.20 but…
  • RIP Superb Owl, hello *Hurr durr I’ma ninja sloth*
  • This release includes 13,099 changed files, 1,280,295 insertions and 341,210 deletions.
  • More than half of it is yet another AMD GPU register dump. 
  • Some AI bits as well. 

Pro sound on Linux


  • Ever want to install a pro sound card on Linux. 
  • Like, a real one?
  • This is one of the biggest baddest audio interfaces. 
  • Replacing the 9632 in the studio. 
  • Yes, you have to compile drivers. 
  • No, you probably don’t want one. 

Slice of Pi

Tracking Pi 



  • Matt Edmondson presented this research project at the Black Hat security conference in Las Vegas last week.
  • His talk was titled “Chasing Your Tail With a Raspberry Pi”, and you can look at the slides from the presentation to find out more information.
  • Edmondson says that in the future, the device could be modified to send a text alert instead of showing them on the screen.
  • Also, a GPS unit could be added so you can see where you were when you were being tracked,
  • And something I really found fascinating:  He is also interested in adding the capability to detect tire-pressure monitoring systems that could show recurring nearby vehicles.
  • Paranoid people have hobbies too. 
  • For around $200 you can build a handy tool that scans for nearby devices and alerts you if the same phone is detected in a 20 minute window. 
  • In theory this could let you know that you are being tailed or driving in LA. 
  • It fits in a shoebox and runs on a Pi3. 
  • A portable charger powers the system and a handy touchscreen shows the alerts. 
  • It includes an ignore list for known devices. 
  • I can think of several ways to make this a highly irresponsible IRL game. 
  • Moral of the story, power down your mobiles when tailing someone. 
  • Or put a few airtags behind the license plate, like a normal person.
