Interesting observation, that in 20 years installer iso size grew almost ten times: from 643M CD to current 5.7G image, that won't fit even on single layer DVD (not that someone are still using those).

I was also surprised how little difference "default selection" and "extended selection" makes in disk space usage - "extended" is taking up only 1GB more of disk space.

I’d like to pick the brains here on HN. I’m looking to do something like autoinstall for my office but is there an easier way have my employees do their own thumb drive (remote users) and get the config they need from me? I’m looking for an MDM Intune like enrollment that’s easier and configured it a certain way. I’m not in a position to use and manage Puppet.

The installer (subiquity) supports the "autoinstall" config files embedded in the install USB/ISO if you want. You can also just point the USB/ISO's autoinstall to an HTTPS address so an update doesn't require spinning new install media (does require the install start with some form of network access then). If you have wildly technical users only then they can even just have them type the autoinstall web address in the grub entry before the standard install media autoboots the entry (this falls apart the second someone isn't ultra techncial). In any of these cases the autoinstall file can still handle both the installer as well as post install custom scripts to do whatever you need but then it's done.

For long term management/enrollment you'd need to look at something beyond just putting stuff on the installer USB/ISO. Ubuntu has Landscape for this but there are some alternatives. Just depends on what you need to manage long term and what you can realistically do (e.g. you note you aren't in a spot to manage something like Puppet).

Will I finally be able to use a bluetooth headset's high quality audio output and its mic at the same time without significant changes in the terminal? It's getting embarrassing that every other mobile and desktop OS has no problem doing this but not Ubuntu.

I think this is the result of how bluetooth itself works for bi-directional voice headsets, no? I do get bad quality on every OS when I have to do this, unless it has to do with the audio codec.

My windows 11 computer does the same thing. It’s because of the limited bandwidth in Bluetooth that it has to lower the audio quality

From what I understand a significant amount is Nvidia drivers and Nvidia stuff.

Ah good times. I started out with one of the early ones, maybe 4.04 or something like that. Ubuntu was my first Linux, and then Mint. Unfortunately, for work purposes, I had to switch to MacOS (not a bad OS), but I still miss Linux from time to time, especially reading about that story on the frontpage about people losing access to their Apple IDs. I think I'll give it another shot soon...

4.10 was the initial release, afair :) With 6.06 (postponed by two months to "get the release right", due to the extended support cycle) as the first LTS release. I fondly receiving 5.xx-release-CDs in the mail and distributing them on our uni campus and in schools back in the day!

What desktop os? MacOS doesn't work well with Samsung stuff regarding quality, Windows 11 + Microsoft Teams = quality is somehow worse.

The "solution" other vendors take is to maintain the high quality bluetooth audio output to your headphones while using your laptop's microphone as input. They basically don't use your headset's mic in order to keep your headset in A2DP mode for high quality audio. You can also easily configure this in PulseAudio Volume Control.

You can't work around the fundamental limitations of Bluetooth protocols like A2DP without cheating and using another microphone somewhere else. You can't use the headset mic when receiving high quality A2DP audio, ever, no matter how hard you try. It is a limitation of the Bluetooth standard.

When you switch the device into headset mode the quality turns to potato because it uses bidirectional audio codecs from the stone age in HFP/HSP mode with mSBC or (god help us all) CVSD.

I don't need it often, but I've used bluetooth earbuds (with mic) and Xubuntu LTS 22.04. No problems at all.

Will be installing in a week or two. I'm not a fan of snap, and I know Mint doesn't use it (by default, anyway), but I'm used to Xubuntu and will stick with it for now.

Apparently, the upgrade path isn't quite ready yet. If you're installing now, do a fresh install.

One advantage with standardized workstation OS images, is the bugs/updates/compatibility only requires a 1 support ticket solution.

Deploy a gpg signed public script to periodically download and install updates from a public server. i.e. anyone that has to update knows the package is from you, and the machine role is pre-defined by you with a config file in "/etc/example/myhost.conf". If secrecy is required, than publish host specific encrypted public payloads named for their primary interface MAC.

This is how to handle clowns pulling drives in colocation data-centers.

Cheers =)
