  • Hahaha. Common problem with multiscreen with different resolutions. Your laptop screen is below and left of your main display, and X11 renders this black “virtual screen”.

    There are multiple solutions:

    a) Set your screen resolution and position through KDE Plasma SystemSettings and push the button “apply to SDDM configuration” (I think Plasma 6.0 removed this option, try to find it in the SystemSettings KCM SDDM section).

    b) The another solution is the old one. Create a file into /etc/X11/xorg.conf/display.conf with the proper values of position and resolution. Search in a wiki about examples (archlinux wiki?).

    c) There is a third one that I used few years ago. SDDM allows you run any command after the screen initialization. So you can exec your xrand command here. Search about /etc/sddm.conf







  • I used Tekton for the last two years, and I didn’t like it. One of the reasons is the community split around Tekton Hub between versions 3 and 4. Another reason is that it’s not very Kubernetes native. While you write YAML, there are a subset of instructions that limit you regarding mundane things you can do on Kubernetes but Tekton doesn’t support, such as mounting different PersistentVolumeClaims or setting tasks by platforms or nodes (amd64, arm64, etc).

    I was so frustrated that I created my own Kubernetes-native CI/CD solution. Currently in development phases (when it is done, I will publish it here). This one uses real native Kubernetes components (jobs). You create Webhooks that launch Workflows, and Workflows can launch other Workflows or Jobs. You can do anything in a Job with no limitations other than Kubernetes itself. Take a look if you want: https://github.com/jlsalvador/simple-cicd








  • Hehe. Or they could send a 0 to your fan velocity. Or flash/lock (setting the flash bit to 0) your BIOS through ACPI calls. Even stolen your Steam token credential. I saw an example that runs commands as a Systemd volatile user service. There are a few POCs on GitHub about recovery passwords from the browser (sand-boxed environment) for generic environments. I think that everyone here is old enough to understand the consequences of our acts.
