How do I troubleshoot a black screen on #KDE #Plasma? I am able to launch apps just fine, but:
- the desktop is all black (no start menu, global menu etc, and the desktop background isn't getting rendered)
- the window decorations are HUGE.

Is there any easy way to debug this? I had initially suspected this was due to my using #Stylix on stock #archlinux, but no, disabling it didn't change a thing (apart from the theme).

I do have custom desktop effects and window decorations installed; so I suspect that might be the issue. How do I disable them if systemsettings does not launch (for some weird reason)?


It's definitely not a kernel issue (I've tried on the stock Arch kernel and the CachyOS kernel), and it certainly isn't a graphics issue (stock mesa etc, and I don't have a dGPU on this machine).


Will send screenshots in a while. Any and all help appreciated! Thanks in advance. Toots and boosts welcome.

For those who are wondering why my projects are so silent, I moved to my own Forgejo instance at https://code.spoljarevic.sh

From there I will continue my journey.

Tho I didn’t have lots of time to work on them, and they will slightly change.

Due to an upcoming server migration, new tools and my personal life, everything got slow.

But I already finished some open issues on the Ansible Project and will go into testing after my vacation.

It shall be finished this month or I’m no longer trusting myself.

Next month will be nothing since I’m gonna focus on chess openings and the month after I’m working on a Knowledge Base (fork of hyprland wiki)

After that, everything should go normal again.

How can I take part in update a package in #Aur? #ArchLinux

Apparently the Fairphone 5 microphone not working with automatic wireguard call profile switching was just a race condition with q6voiced:

https://gitlab.postmarketos.org/postmarketOS/q6voiced/-/work_items/3

This means I now have calls working at a usable level with great quality on the Fairphone 5.

Since ArchLinux users must love the bleeding edge, I'm shipping this as default with my packages, so it should work out of the box going forward:

People keep asking me how I knew to stock up on CPUs and RAM before the AI hardware choke. Anyway, I think I'm just about done configuring my optiplex #archlinux router. It's currently operating behind my modem, but it is responsible for the whole wireless network right now. And wow! Just using the hagezi configuration file for blocking is great. next, I think I'll recreate my "stream hole" configuration for the rest of the TVs in the house. #selfhosted

When two Hetzner servers died at the same time

On May 12, 2026, two of my Arch Linux + LUKS servers at Hetzner became unreachable at the same moment. Both had been running for 4+ months without issue. Both had received the same pacman -Syyu the day before, but had stayed on the old kernel until the morning the websites stopped responding. I rebooted — SSH never came back. nmap -Pn -p 22 showed filtered from anywhere. No ping. No banner. The Hetzner Robot panel insisted the hardware was fine.

Several hours went into hypotheses that turned out to be wrong:

• The encryptssh initcpio hook referencing a /usr/lib/initcpio/udev/11-dm-initramfs.rules file that no longer exists. Real bug, no boot impact — the initramfs rebuilds anyway.
• PermitRootLogin no in sshd_config. Real misconfiguration, fixed it, didn’t help. A refusing sshd shows closed, not filtered.
• Predictable interface-naming drift after the systemd 260 upgrade. Patched the .network config to match by MAC. Useful hardening; not the cause.
• Stale GRUB stage1 + core.img in the MBR. Arch never re-runs grub-install after a grub package upgrade. Refreshed it. Still filtered.
• Kernel 7.0.5 regression. Downgraded to 6.18.3, the kernel that had run for 4 months. Still filtered. So the kernel itself wasn’t it either.

The clue was in the persistent journal: a single recorded boot from December 31 to May 12 10:13 UTC, and absolutely nothing after. Every reboot since the upgrade was failing before systemd-journald could flush to disk — so the failure had to be in the initramfs, before the root filesystem was even mounted.

What it almost certainly was

Hetzner Dedicated servers configure the initramfs network with ip=dhcp on the kernel command line. That depends on Hetzner’s DHCP server replying to whatever request format the current kernel sends. Somewhere between kernel 6.18 / iproute2 6.18 and kernel 7.0 / iproute2 7.0, the request format changed enough that Hetzner’s DHCP stopped responding. Effects:

• Old kernel at runtime kept the interface already configured (Phase A — 32 hours of healthy operation after the package upgrade).
• New kernel cold-boots, hits DHCP, never gets an IP, dropbear cannot listen, port 22 stays filtered.

Hetzner’s own documentation has been quietly moving away from ip=dhcp toward static IPv4 in the kernel command line. The fix is exactly that:

GRUB_CMDLINE_LINUX="cryptdevice=/dev/md1:cryptroot ip=A.B.C.D::GATEWAY:255.255.255.255:hostname:eth0:none"

One line in /etc/default/grub, grub-mkconfig, reboot. No more dependency on Hetzner’s DHCP responding to whatever your current kernel sends.

Why it matters for anyone running this stack

If you run Arch on Hetzner Dedicated with full-disk encryption and remote unlock via dropbear, the ip=dhcp shipped by installimage is a latent bug. It can keep working for years and then break overnight, on every machine you have, after a routine pacman -Syyu. The static-IP version is what Hetzner now recommends and removes the entire dependency.

Tooling

While debugging, I turned the whole rescue / chroot / diagnose / fix workflow into a Python CLI (hal) — including hal fix static-ip, which derives the static cmdline directly from your existing systemd-networkd .network file:

→ github.com/kevinveenbirkenbach/hetzner-arch-luks

Single command, idempotent, reversible (the original /etc/default/grub is backed up to .hal-backup). If you’re on this stack, switch to static IP before the next kernel upgrade catches you.

Today I learned #BespokeSynth on #ArchLinux freezes when trying to save a project. After I force terminate the application, the save file dialog window appears. On #MXLinux I was able to get my music done though, so that's good!

Arch Tip týdne: pacman jako profík

Hey y'all !

I have successfully and after a full day's work, been able to migrate the #XeroLinux #Hyprland config to LUA.

Also the standalone script has been killed off. We migrated to only have it in T.U.I. Wiki was updated reflecting this change.

After two weeks of wrangling, finally got the next batch of AV1 packages built for Arch into the repo. Should be back on the regular schedule of weekly releases unless something else rears its ugly head.

- Some packages require GCC 15 and absolutely hate GCC 16
- Zig 0.16 is not an option for a lot of stuff
- VapourSynth API v3 C headers are no longer included with the Arch Linux package, so had to grab those from the repo and get them to the right spot

I am idly considering installing #NetBSD on my current #ArchLinux (BTW) laptop just to have #Emacs on a different platform.

I'm kind of finicky, I guess. :chaos:

Updating my #ArchLinux systems is usually pretty quick, but on the one system where I have an #NVIDIA GPU and have CUDA installed the process takes notably longer (primarily because the download sizes are so much larger).
