Bug ID: 460643
Summary: lookandfeeltool crashes/doesn't work when invoked by
other tools such as cron, darkman...
Classification: Plasma
Product: plasmashell
Version: 5.26.0
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Global Theme packages
Assignee: plasma-b...@kde.org
Reporter: filippo27...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
SUMMARY
I used the tool darkman (https://darkman.whynothugo.nl/) to automate dark theme
switching at night. This has stopped working since updating to Plasma 5.26.
I've found that lookandfeeltool, which was invoked by darkman via scripts,
crashed every time darkman activates, but invoking it manually via command-line
works. Using cron to invoke lookandfeeltool also appears to not work, but I
have not found coredumps caused by that.
