I've been busy for a couple weeks but needed to get this returned soon if Linux wouldn't work. I wanted to run primarily Linux but thought I'd keep some of the disk as Windows. It won't work yet.? I finally got Debian and then Ubuntu sticks to be recognized by the boot screen (F12) but neither would boot.? Both went to never-never land.? The problem is the chip is too new.? It's a Qualcomm Snapdragon X Plus chip with 8 cores. However, it seems too new. Supposedly, Qualcomm hacked Debian enough to get it to run when they announced the chip.? Usually, Qualcomm never shows Linux and only Windows.? The Qualcomm mods have not reached the Linux distributions yet.? With the right amount of hacking people got Debian 12 and Ubuntu 24.10 to work.? I'm not anxious to do that. I will return this nice laptop and try something else. Thanks for all your help and ideas! Bill P.S. Sorry I offended some by using the term Windoz.? I only use Windows about once every 5-10 years and once I get in there my hate for it always grows? -------------- next part -------------- An HTML attachment was scrubbed...

I picked up a lenovo slim 7x last year, and It's still not an 'out of box' experence. There's a flow of non upstreamed patches getting things working. I've been using jhovold's tree. So for example for the not yet released 6.13 kernel: https://github.com/jhovold/linux/tree/wip/x1e80100-6.13-rc6 53 non upstreamed patches. :( ( I build a fedora rawhide kernel rpm from that at: https://copr.fedorainfracloud.org/coprs/kevin/x1e80100kernel/ ) Even that isn't enough to get things fully working, you need to pass the correct devicetree from that kernel in grub or the like. With that, everything works here except for the webcam and speakers. So, yeah, those patches will have to land in the mainline kernel and then people will need to sort out the devicetree handling before things will just work. ;( So you likely made a good call for now... kevin -------------- next part -------------- A non-text attachment was scrubbed...

It was good to see two new faces in the group tonight! My own report today included that I have been fixing bugs in the GNU debbugs bug tracker. Some years ago someone on that system decided to redirect all of the output from cron jobs to /dev/null. Not a great solution! I removed that redirection assuming that I would get hammered with email from errant cronjobs. And I was right. Lots of email from */10 and */30 and other jobs. I have been slowly working through the errors. Pick one and chase it down to root cause and fix it. Then move to the next one. Alex won the recent CTF Capture The Flag challenge from NoCo Hackers! Yay! Alex gave us the story of the recent challenge. Morey talked about AI. Talked about espeak advancements. Remote access to his phone. The Fort Collins downtown visitors center. It's not really for visitors. It's a citizen's center. Basically community meeting space. Apparently no URL available? https://huggingface.co/ Kyle demonstrated "pyspread". A python based spreadsheet. Mature spreadsheet. Python can be run in each cell. https://pyspread.gitlab.io/ Evelyn told us a story of woe where through the course of events of having installed Ubuntu with LUKS there was an encryption event which left her machine encrypted and unable to decrypt it due to being unable to supply the correct decryption password. The moral being to be careful with fully encrypted systems because the data is truly inaccessible without the passphrase. James talked about his desktop project. Which is the top of a desk. Woodworking project. He is making an oak top for his desk. Somewhat of a long wood working project but the top is now looking lovely and soon it will be the top of his desk. David stood up and said that he has been Dew free for X days from his Mountain Dew addiction. Hahaha. Then a short tale of his current GNU/Linux adventures. Stephen had two topics. OpenZFS now has a new online raid capacity expansion. Playing with rclone. It's like rsync but does a bunch of additional features. Brian talked about file sync to onedrive using rclone. With the advantage of onedrive keeping its own versions which can act like a backup for that purpose. Morey talked about the performance increase moving to a WiFi-7 Access Point. He just upgraded and is getting 800 Mb/s across the wifi now.

To clarify, my issue was related to ZFS + LUKS. I didn't save, or wasn't offered the opportunity to save the ZFS recovery password in plain text, when I set up my laptop, years ago. Then when I needed to do a recovery, I was quickly in the weeds. So, if you are running ZFS+LUKS, check to see if you have the ZFS rpool key file in plain text. Note, this is a very unusual setup, so I doubt there are more than a handful of people running with both ZFS encryption and LUKS encryption. I used my LUKS password daily, so I never forgot it, but had no idea there was even a separate ZFS encryption key, let alone that I didn't have a plaintext recovery file, until it was too late. Entirely self inflicted, by being on the cutting edge of tech in open source. I hope this helps, Evelyn On Tue, Jan 14, 2025, 7:29?PM Bob Proulx wrote: > j dewitt wrote: > > What: Tuesday January 14th, 2024 NCLUG Meeting > > I was late arriving to the meeting tonight while introductions were > already in process.
