Bug ID: 462738
Summary: SDDM can't load Breeze theme with system-provided
plasma-workspace
Classification: Developer tools
Product: kdesrc-build
Version: Git
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: mp...@kde.org
Reporter: m...@ratijas.tk
Target Milestone: ---
SUMMARY
Apparently, install-sessions.sh can't provide SDDM with a self-contained
environment for loading Breeze theme/look-and-feel. System packages are still
required, and if they are not found — SDDM will fail to load Breeze, and
fallback to default theme with a bunch of error messages.
STEPS TO REPRODUCE
1. $ pacman -Rndd plasma-workspace
2. $ kdesrc-build ${your-rebuild-world-arguments-here}
3. $
$HOME/kde/build/kde/workspace/plasma-workspace/login-sessions/install-sessions.sh
4. Reboot
OBSERVED RESULT
Default SDDM theme loaded, and a bunch of error messages printed to the
journal:
