Found 2026-09-25. Compiz 0.9 (ini backend), XFCE, GTX 760 / NVIDIA 470, focus-follows-mouse, no autoraise. SYMPTOM A GTK4 window is mostly transparent while it is the active window: background, list bodies and rows are not painted, so the wallpaper and the window behind show through. Only widgets that damage themselves (buttons, headers) still draw, plus the WM title bar. The same window renders correctly while inactive. Affects all GTK4 apps; GTK3 and Qt are unaffected. ...

Symptom — the machine resumes, fans spin, disks come back, but the panel stays dark until you move the mouse or press a key. Cause — this is not a GPU or hibernate-image problem. On an X11 session with lightdm + light-locker, XFCE locks the screen on the way into sleep (xfce4-power-manager/lock-screen-suspend-hibernate = true) and the panel is put into DPMS “off”. Nothing restores DPMS on resume: X only forces the monitor back on when it sees an input event. Hence “dark until I touch something”. ...

pacman pacman -Si <package> | grep Version # version in the repo pacman -Qi <package> | grep Version # version installed Or for all ignored packages at once: pacman -Qu This lists everything with a newer repo version, and packages in IgnorePkg are still shown, marked with [ignored] at the end of the line. A plain pacman -Syu also prints a warning per ignored package with the old and new version before it lists the rest. ...

The biggest blunders documented here: lib32-audit: sudo pacman -Rdd lib32-audit then update your stuff. Background - that lib went into AUR, but had a back reference. (Manjaro only) The infamous invalid pgp message (mostly Manjaro, did not observe that at ARch or EndevourOS) Manjaro - First try sudo pacman -Syy sudo pacman -S manjaro-keyring archlinux-keyring IF THAT fails DO: sudo rm -rf /etc/pacman.d/gnupg /var/lib/pacman/sync sudo pacman-key --init sudo pacman-key --populate archlinux manjaro sudo pacman -Syyu On real Arch Linux do: pacman ...

Create a service that downloads the latest versions without installling them. Needs a service and a timer service. The Code: sudo nano /usr/local/bin/arch-bg-download.sh #!/usr/bin/env bash # Script to pre-download official repo and AUR updates in the background. # 1. Update package databases and pre-download official repository packages echo "Pre-downloading official repository updates..." pacman -Sywq --noconfirm # 2. Pre-download AUR updates if yay is installed (Runs as regular user context, not root) if command -v yay &> /dev/null; then echo "Pre-downloading AUR updates..." # Find the primary human user to execute yay safely without root permissions REAL_USER=$(loginctl list-users --no-legend | awk '{print $2}' | grep -v 'root' | head -n 1) if [ -not -z "$REAL_USER" ]; then sudo -u "$REAL_USER" yay -Syua --downloadonly --noconfirm fi fi echo "Background download finished successfully." sudo chmod +x /usr/local/bin/arch-bg-download.sh ...

Snap ignores your theme and selects one of the co-packed snap themes. This is one of the drawbacks of snap. You could remove Firefox from snap with: sudo snap disable firefox snap remove --purge firefox For Ubuntu 22.04, the empty Firefox Deb is pre-installed as a wrapper. You have to remove it via command: sudo apt remove --autoremove firefox On Ubuntu 22.04, you’ll have to add a ppa now: ...

Publishing to PyPI First time only: Create an account at https://pypi.org Create an API token under Account Settings → API tokens Install twine: pip install twine Save your token in ~/.pypirc: [pypi] username = __token__ password = pypi-YOUR-TOKEN-HERE Every release: Run gradle build_all Build the wheel and tarball: cd dist/pypi && python -m build Upload: twine upload dist/* The GitHub Release upload (step 2 for AUR) is the only manual step that ties the two together — the AUR PKGBUILD’s source URL points to that release asset for its MD5 check.
