I have just switched from to KDE5 (on Kubuntu 15.04). On KDE 4, I could double click on the window title and it expanded full screen. This does not work anymore with KDE5 even though system settings->window behaviour -> window title->double click is set to maximize. When I double click, the mouse curse changes for a second into a cross like cursor. May be it has something to do with the fact that I have a dual monitor configuration. Reproducible: Always
might be related to bug #346889 can you please attach ~/.config/kwinrc ?
(In reply to Thomas Lübking from comment #1) > can you please attach ~/.config/kwinrc ? here it is: [Compositing] OpenGLIsUnsafe=false [Desktops] Number=1 [Effect-Zoom] InitialZoom=1 [org.kde.kdecoration2] BorderSize=Tiny ButtonsOnLeft=MS ButtonsOnRight=HIAX CloseOnDoubleClickOnMenu=false library=org.kde.breeze
mhh-hmmm. "kcmshell5 kwinoptions", does that indicate you're maximizing on doubleclick? if yes, please alter it to something else and check ~/.config/kwinrc again - is there now an entry eg. [Windows] ... TitlebarDoubleClickCommand=Shade ... ?
did as advised, now it looks like this: [Compositing] OpenGLIsUnsafe=false [Desktops] Number=1 [Effect-Zoom] InitialZoom=1 [MouseBindings] CommandActiveTitlebar1=Raise CommandActiveTitlebar2=Start window tab drag CommandActiveTitlebar3=Operations menu CommandAll1=Move CommandAll2=Toggle raise and lower CommandAll3=Resize CommandAllKey=Alt CommandAllWheel=Nothing CommandInactiveTitlebar1=Activate and raise CommandInactiveTitlebar2=Start window tab drag CommandInactiveTitlebar3=Operations menu CommandTitlebarWheel=Switch to Window Tab to the Left/Right CommandWindow1=Activate, raise and pass click CommandWindow2=Activate and pass click CommandWindow3=Activate and pass click CommandWindowWheel=Scroll [Plugins] windowgeometryEnabled=false [Windows] ActiveMouseScreen=false AutoRaise=false AutoRaiseInterval=750 AutogroupInForeground=true AutogroupSimilarWindows=false BorderSnapZone=10 CenterSnapZone=0 ClickRaise=true DelayFocusInterval=300 FocusPolicy=ClickToFocus FocusStealingPreventionLevel=1 GeometryTip=false HideUtilityWindowsForInactive=true InactiveTabsSkipTaskbar=false MaximizeButtonLeftClickCommand=Maximize MaximizeButtonMiddleClickCommand=Maximize (vertical only) MaximizeButtonRightClickCommand=Maximize (horizontal only) NextFocusPrefersMouse=false Placement=Smart SeparateScreenFocus=false ShadeHover=false ShadeHoverInterval=250 SnapOnlyWhenOverlapping=false TitlebarDoubleClickCommand=Maximize WindowSnapZone=10 [org.kde.kdecoration2] BorderSize=Tiny ButtonsOnLeft=MS ButtonsOnRight=HIAX CloseOnDoubleClickOnMenu=false library=org.kde.breeze behaviour has not changed.
Ok, config is written (and probably read) in the correct location, also "Maximize" is the default. Let's assume this works, you could also try other settings for confirmation (eg. the mousewheel setting) I noticed that the decoration does not honor the system wide drag start offsets (time/distance) => What you describe (cursor change) seems like a degenerated move, do you maybe have trouble to perform a "clean" doubleclick (ie. w/o accidentally moving the pointer, common issue on touchpads)?
There seems an issue with the doubleclick event. *** This bug has been marked as a duplicate of bug 345473 ***
