Everyone Needs AI, Right?

Shibblet — Thu, 21 May 2026 18:39:13 GMT

Just read an article on ombubuntu.co.uk called: Ubuntu is Getting AI Features in 2026 – Here's What's Planned

I am starting to feel the line between integrated AI, and non-integrated AI becoming blurred.

Why do these major companies (Canonical, Microsoft, etc.) believe that AI needs to be integrated into the OS?

In Microsoft's case, they are forcing users to deal with CoPilot. It "can" be removed, but it's not as simple as clicking on "Uninstall."
I'd imagine that Canonical will allow it to be "opt-out," as in easily removable... but not 100% sure.

Regardless of the integration... what are the reasons for this? I mean, some of us don't want or need an AI companion in our OS... so why force it?

keyboard shortcuts

die.boer — Wed, 20 May 2026 06:58:00 GMT

i'm trying to apply a shortcut to switch between open apps on the titlebar , i don't want to use alt+tab or meta+tab (which only seems to switch between open windows, i want to switch between apps), i want to use a single key (like F2) to switch between them
tried to find something in keyboard shortcut settings but not coming right

meaning i want to switch between those for example by pressing F2

I was reminiscing about my "tech" journey...

oshunluvr — Mon, 18 May 2026 21:54:59 GMT

High School, 1978-80, 16-18 yrs old, programmed an IBM 360 mainframe using Fortran IV w/WATFIVE and punchcards.

University, Mainframe (don't remember the model) via paper punched tape, Assembly, COBOL, RPG II, also got my hands on early desktop PCs: Apple ][, IBM, and Radio Shack/Tandy.

...ended up in a different career...

For home use had Apple ][c, Timex Sinclair (used a cassette tape to load the OS!), IBM PC w/8-bit processor, and many, many others later.

At 46 retired from career and got my first "real" tech job. Became a Simulation Expert running, repairing, upgrading, and training on networked simulation systems with 27 or more PC's running Linux and Windows. Learned Postgresql and wrote hundreds of queries to make my job easier. Managed 60+ systems all over the country and had 70-80 employees.

Retired again.

I saw, punch cards, punched tape, multi platter hard drives the size of washing machines, tape drives as big as a refrigerator, cassette tape storage, 8", 5.25", 3.5" floppies, the first Apple released personal desk top hard drive that cost about $1500 in the early '80s.

Now I just doom scroll here and reddit and a couple other forums looking for good questions to answer and problems to solve.

[Soapbox]Distro Gaming-Hopping

Shibblet — Thu, 14 May 2026 19:46:42 GMT

So, I've been a Kubuntu user since 2010. Don't get me wrong, I've done my fair share of distro-hopping over the years. I actually have two computers. One runs Kubuntu (religiously), and the other I try different distros on. But my fallback / daily-driver is Kubuntu.

Something I have noticed over the past few years with all of these new "gaming" centered distributions that come out. Namely CachyOS, Bazzite (Fedora), PikaOS, and other similar "gaming-spin-style" distributions. They are all touted as being superior for gaming... but what I have noticed, is that these Distros all seem to have a neat features.

CachyOS has packages that are optimized for Zen3 and Zen4 architecture, which would give better performance overall... but not necessarily for the Windows game you just downloaded in Steam.
PikaOS is streamlined, and has a minimal DE, but again, minimal doesn't always mean more performance for a Windows game running under Proton.
Bazzite might have a bunch of extra game-compatibility features built in just to make it so games will run by default, but this is not always the case either. Some games just require a little tweaking (Thank you Glorious Eggroll!)

Then there is Manjaro, Endeavor, Garuda (Arch based) with access to the AUR. Again, the AUR has many helpful tools for gamers, but they don't actually assist with better performance.

An finally, I come back to Kubuntu. I always fall back here, because to me, it's stable, runs all the apps I use, and the performance is just as good as all of the other distros listed above... Seriously, within 2-5 fps (averaging around 90) of all the games I play. I know gamers are all about performance, but at what cost? Installing a new OS for every game you install? Manjaro gives me 113fps in Tomb Raider (2016), Kubuntu gives me 115fps, CachyOS gives me 117fps, and Garuda gives me 112fps in X11, but 43 with Wayland... Come on... I mean, buttery-smooth FPS is (generally) 60+ fps, for enthusiasts 90+, and for competative gamers 120+

Regardless, we are distro-hopping to get ranges between 110-120fps... and at this point, it really doesn't matter. I mean 10fps is a big deal if you're normally getting 30fps, but not if you're over 60fps...

So, I ask... is it really imperative we pick a gaming centric distro to get the absolute best performance? Or is it better to stick with a tried, tested, and true OS like Kubuntu?

[RESOLVED]Odd SDDM behavior - Face icons only showing for one user

oshunluvr — Tue, 12 May 2026 15:12:50 GMT

I noticed this a while ago but just today decided to address it:

I have 3 users on my system, but the login greeter only shows one of them. The users are Lisa, Stuart, Trevor.

Here's what I've checked:

Output of file command:

Code:

/home/lisa/.face: PNG image data, 512 x 512, 8-bit/color RGBA, non-interlaced
/home/stuart/.face: PNG image data, 512 x 512, 8-bit/color RGBA, non-interlaced
/home/trevor/.face: PNG image data, 246 x 246, 8-bit/color RGBA, non-interlaced

Output of getfacl command:

Code:

# file: home/lisa/.face
# owner: lisa
# group: lisa
user::rwx
group::r-x
other::r-x

# file: home/stuart/.face
# owner: stuart
# group: stuart
user::rwx
group::r-x
other::r-x

# file: home/trevor/.face
# owner: trevor
# group: trevor
user::rwx
group::r-x
other::r-x

So all three files are the same type and settings. Also, all three faces show in System Settings > Users, just not on the login screen.

The only differences I can see are:

trevor/.face is a different size.
stuart/ also contains a symlink to .face as .face.icon.
lisa is first alphabetically.

I'm going to try a way to test the alphabetical factor.

None of the above should make a difference but anything is possible. If anyone has an idea of what else I could look at, it would be appreciated.

EDIT: Adding a user name "Bob" did not change the face behavior. Bob has a face icon that does not show. Lisa still is the only face showing.

Low charge rate for PD on a Thunderbolt USB C. Dell Latitude 7490

theyoyomaster — Sun, 10 May 2026 19:31:50 GMT

I have a Latitude 7490 that I primarily run Kubuntu on but dual boot to Windows 10 for a few things that can't be done on Linux. I've had it for about a year and a half and am finally getting comfortable in the environment but still am working to learn the higher level stuff. I recently had to replace my laptop due to tornado damage but was able to save the hard drive and swapped it into an identical refurbished one from the same vendor where I got my first one, except this one has a thunderbolt port. It's a super nice option and I would love to ditch the barrel plug for charging but for some reason it is limiting the charge rate in Kubuntu to 40 watts. I have one of the new smart chargers from Anker and can see exactly what wattage, amps and voltage each device is drawing. During post and in Windows it draws 60 which is what the barrel plug delivers (apparently there's a 90 watt barrel plug option and Dell's documentation says TB3 can go up to 100 but I'd be happy with 60).

I've been digging around and can't find anything that would limit the negotiation in Linux, but since I can literally see it charging at 60w until the login screen pops up and then drop to 40w it's pretty obvious that something software related is limiting it. I tried updating the Bios and TB firmware but nothing changed on charge rate. Anyone have an idea of how to start tracking this down?

The name for Kubuntu 26.10 has been released

NoWorries — Sat, 09 May 2026 10:36:36 GMT

The name for Kubunto 26.10, Stonking Stingray has been released at:

https://www.omgubuntu.co.uk/2026/04/...name-confirmed

As Kubuntu 26.10 follows the same naming convention as Ubuntu I have taken the liberty to modify the above reference for Kubuntu with it's scheduled release on the 15th October 2026. Following the alphabetical tradition, this interim release has the name "stonking" which a British slang for something huge or impressive. The term Stingray is for a boneless fish found in coastal waters around the world as well as in Australia. It lives close to the seabed, often partially buried in sand and some have been stung by the barb in its tail. So I am not sure everyone will appreciate this name but it is the best for the SS name required - I hope we will all get to enjoy this name and the extra features it will provide.

Key Details for Kubuntu 26.10 "Stonking Stingray" are:

Release Date: October 15, 2026.

Release: September 24, 2026.

On-board webcam not cooperating

DezineDude — Fri, 08 May 2026 17:34:44 GMT

Newbie here! I'm dual booted now to Kubuntu 24.04 and I do like it however I cannot get built-in webcam working. So I'm ZOOM less! It works on the hated WIN11 side. I have tried Webcamoid, Kamoso, guvcview and cheese to ZERO success.

Linux exploit instantly grants administrator access on ...

Linux exploit instantly grants administrator access on most distributions since 2017 —
cryptography optimization snafu grants root privileges to local users

(It's fixed.)

This.

It's above my head, but interesting.

... they found it with the help of an AI assistant. Given that the source code for the Linux kernel is by definition public,
in theory, any serious attacker would find it just as easily.

Not able to reply in own topic as a new user

Caelarius — Thu, 30 Apr 2026 18:25:44 GMT

I created an account today, validated it and made a new topic (https://www.kubuntuforums.net/forum/...ion#post691594) I got some responses to it, but find myself unable to reply to those responses. I tried DM-ing the repliers, but that also does not work: I get a message that I do not have access to that. I read something about building up karma/rep in order to get more rights. Which is ok, but I really do not want to create a new topic to be able to continue the discussion from the first topic while I don't have these rights yet. Can the user rights for new members be set so that they can reply to topics?
