If I had asserts enabled, I would hit this perhaps: Q_ASSERT_X(currentMode, "applyKScreenConfig", "currentOutput has returned a null XRandRMode*"); Now building with (however it is incorrect): --- a/backends/xrandr/xrandrconfig.cpp +++ b/backends/xrandr/xrandrconfig.cpp @@ -165,6 +165,9 @@ void XRandRConfig::applyKScreenConfig(KS XRandRMode* currentMode = currentOutput->currentMode(); Q_ASSERT_X(currentMode, "applyKScreenConfig", "currentOutput has returned a null XRandRMode*"); + if (!currentMode) + continue; + QSize size = currentMode->size(); int x, y;

Git commit 1d9ac012e857036bb8814cc84c9cf10bb57ca40c by Dan Vrátil. Committed on 09/09/2013 at 16:43. Pushed by dvratil into branch 'master'. Refresh modes when currentModeId points to unknown mode Sometimes drivers insert or remove modes, so when currentModeId points to a mode that we don't have cached, we must refresh the local cache. This also fixes a crash that occured when currentModeId would be pointing to a mode that we don't have (even after refreshing modes) REVIEW: 112604 Related: bug 323107 FIXED-IN: 1.0.2 M +43 -20 backends/xrandr/xrandrconfig.cpp M +15 -0 backends/xrandr/xrandrmode.cpp M +4 -0 backends/xrandr/xrandrmode.h M +5 -0 backends/xrandr/xrandroutput.cpp M +3 -1 backends/xrandr/xrandroutput.h http://commits.kde.org/libkscreen/1d9ac012e857036bb8814cc84c9cf10bb57ca40c
