--- Comment #5 from Xavion <xavio...@gmail.com> --- Sebastian: I'm not sure whether you're talking to Herb or myself (or both). I currently can't reproduce this issue at my end (on KScreen v5.8.1). For the record, the "QT_PLUGIN_PATH" environment variable is not set here. I guess this means the KScreen backend is being found in the default location (so no changes are necessary). Nonetheless, remember that I was only seeing the "No KScreen backend found" error message *half* the time. I was definitely not fiddling around with environment variables in-between attempts (e.g. just for kicks). This leads me to believe that the cause of the problem lay elsewhere. One thing I will note now is that the settings are blank - i.e. the dialog looks like that of the second screenshot (albeit minus the error message) - whenever I launch KScreen via 'sudo' (or 'su') these days. So, I will provide the output you've requested in this (i.e. 'su') case. Note that the "QT_PLUGIN_PATH" environment variable is still not set. xavion@Desktop /h/xavion> kscreen-doctor --info Environment: * KSCREEN_BACKEND : [not set] * KSCREEN_BACKEND_INPROCESS : [not set] * KSCREEN_LOGGING : [not set] Logging to : /root/.local/share/kscreen/kscreen.log Preferred KScreen backend : KSC_XRandR.so Available KScreen backends: * KSC_Fake.so: /usr/lib/qt/plugins/kf5/kscreen/KSC_Fake.so * KSC_KWayland.so: /usr/lib/qt/plugins/kf5/kscreen/KSC_KWayland.so * KSC_QScreen.so: /usr/lib/qt/plugins/kf5/kscreen/KSC_QScreen.so * KSC_XRandR.so: /usr/lib/qt/plugins/kf5/kscreen/KSC_XRandR.so * KSC_XRandR11.so: /usr/lib/qt/plugins/kf5/kscreen/KSC_XRandR11.so xavion@Desktop /h/xavion> kscreen-doctor --outputs (No output - it just hangs indefinitely and I have to hit "Ctrl+C" to quit each time) -- You are receiving this mail because: You are watching all bug changes.
