unity8 has a big log file, because qtmir has all debug logging info turned on by default. This can be changed just for unity8 by setting adding this env var to its upstart job: QT_LOGGING_RULES="*.debug=false"
Alternatively can apply this policy for all Qt apps in the system by creating ~/.config/QtProject/qtlogging.ini with these contents: [Rules] *.debug=false Could use "*=false" to hide nearly all app output. For more info, see http://doc.qt.io/qt-5/qloggingcategory.html I think the latter suggestion is easiest to implement should we want to turn the warnings back on for developer mode. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to upstart-app-launch in Ubuntu. https://bugs.launchpad.net/bugs/1414039 Title: App logging should be off by default Status in the base for Ubuntu mobile products: New Status in ubuntu-system-settings package in Ubuntu: New Status in upstart-app-launch package in Ubuntu: New Bug description: We are creating 100s of MBs in log files which are generally unused on production systems Propose to turn app logging off by default and add an option under developer mode to enable it along with additional logging levels like debug.
