Re-Roll RHEL isos to skip the 60sec countdown and media check
by Dan Davis 06 Mar '23

06 Mar '23

Good Afternoon, I'm trying to re-roll a RHEL9 iso to remove the media check and 60s timeout that occurs because rd.live.check is baked into the kernel command line and grub menu. I'd like to use the result with an unattended install. I start by loop mounting the OEM iso image and extracting the contents to a working dir. In the working directory, I've attempted to edit EFI/BOOT/grub.cfg an isolinux/grub.cfg before rerolling the disk with: mkisofs -o output.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table workingdir But after editing either or both, I'm still presented with the 60s default timeout and the media check (rd.live.check) in the kernel commandline. Is there something akin to grub2-mkisofs that I need to do for my changes to the grub.cfg for this iso prior to my re-rolling it? Thank you, Dan

Broken Laptop Screen
by hammerron 01 Mar '23

I have a friend that told me he has kept his laptop stored away because the screen is broken. I do not know if the screen is crack or not operating. I have a monitor from a desktop pc. If I give him the monitor to use with his laptop is there any kind of electrical safety issue? I presume the laptop is windows, and hints on how or if I should tweak the settings? Ron

Tomorrow's meeting is going to be Virtual
by Tim Keller 22 Feb '23

22 Feb '23

Hey Everybody, Last week it was the career fair, this week the trustees have reserved everything.. However, the weather looks like it's going to be a mess. Our meeting for Feb. is going to be virtual. I'd rather keep everybody safe they try to find someplace we can all fit. We'll be at our usual virtual haunt: https://meet.jit.si/WlugMA starting at 7PM. The plan is to talk about containerized distributions, though knowing how our virtual meetings go it'll be a hilarious raucous affair. I hope to see you all online and in March we'll *actually* have a physical meeting! Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Meeting agenda for thursday Feb 16th?
by John Stoffel 15 Feb '23

15 Feb '23

Hi all, Is there an agenda for this thursdays meeting? I can bring an OrganPI 3 LTS I just recently setup. Neat little box running Armbian. Haven't don't anything with it though. I know KiCad 7.0.0 has been released, but I haven't had any time to update my old discussion on KiCad for the new version. So I really can't talk about it too much. I'm planning on being there, but who knows what will happen. John

Solving Nvidia support with image-based distros
by Joshua Stone 15 Feb '23

15 Feb '23

Hey all, I thought I'd share a side project I've been working on, which involves building containers with Nvidia kernel modules and userspace components that work as bootable OS images thanks to "container-native" <https://fedoraproject.org/wiki/Changes/OstreeNativeContainerStable> support within Fedora Silverblue. This approach has several advantages over the traditional package management model for installing out-of-tree drivers, including: 1) Have the install process and QA shift from client side to server side, making a CI/CD model of driver distribution possible. 2) Eliminate the possibility of update failures (i.e., will a , as only container builds with successful runs will be committed to a container registry and updates are delivered with an "immutable" model 3) Modules are signed with one key from a central repo, ensuring that only one key has to be enrolled for all client systems for enabling secure boot support 4) Enable the possibility of supporting multiple driver release streams. i.e., give users the freedom to rebase on 525xx, 520xx, 470xx series drivers, etc, as well as pin to a specific image snapshot in case of a driver regression 5) Have the ability to download a pre-built bootable image from a central repo, or build an image locally with further customizations thanks to the flexibility of the Containerfile format 6) Give maintainers a broader framework for debugging regressions, namely being able to boot into a specific snapshot listed in a bug report It's true that Nvidia has been the source of many hardware issues <https://www.youtube.com/watch?v=iYWzMvlj2RQ>. I refuse to own an Nvidia card because of this. But many Linux users use Nvidia, which I thought would be a great motivation for working on a container-native approach to out-of-three driver support.

Reminder! WLUG Meeting Tomorrow Jan 26th 2023: Topic Frame.work laptop demo!
by Tim Keller 26 Jan '23

26 Jan '23

Hey Everybody, This is a reminder that we've got a meeting tomorrow at WPI! Time: 7pm Location: WPI Student Center Room 128 (Taylor Room) Down below the stairs. Virtual Location: https://meet.jit.si/WlugMA Topic: frame.work laptop demo, passbolt demo Cara Salter has agreed to come and show off her frame.work laptop. This laptop is designed with upgrade ability in mind. Components such as the motherboard can be easily swapped for more powerful versions, etc. I'm also going to show off passbolt <https://www.passbolt.com/>. This is a FOSS password manager. With the massive breach of lastpass, people may want to think about having total ownership of their password stores. This solves that. As usual snacks and refreshments will be provided and afterwards we'll head off and have dinner and keep the conversation going. I hope to see you there!
