I'm running Fedora 23 and I just switched to try out KDE 5 Plasma. I hadn't touched KDE in years, so it's all new to me. Everything has worked beautifully except right click in the Kickoff menu to add an application to Favorites. When I right click it takes up to 30 seconds to bring up the context menu. I've searched the forums and looked through the other right click slowness related issues and none of them match mine. For instance right click anywhere else, including Dolphin, works instantly. I know it's probably something silly that I'm missing as I've been using Gnome for years, since it's the Red Hat default. What is the best way to diagnose this issue, since it only effects the Kickoff Launcher?

can you test as a new user to see if its systematic or your config

same problem if you use an alternative launcher (right click -> alternatives) ? should not be a difference but ...........

during the 30 secs does any unusual i/o or cpu show in ksysguard (you probably will need to add IO Read and IO Write columns)

Nothing unusual on IO in ksysguard. CPU hits 25% for the plasma-shell, and considering I'm running an i5, that's one hyperthreaded core peaking. The alternatives both work the same as the launcher, for what that's worth.

Update: If I move the mouse away from the menu while waiting for the context menu to pop up it causes plasma-shell to crash. It comes back immediately, but it also brings up the crash report window.

no idea

add a launcher to the desktop and try there

try as another user

Any error messages if you launch the Kickoff from the konsole ?

plasmawindowed

...run for example

Code: Select all

plasmawindowed org.kde.plasma.kickoff

which will launch the Kickoff Application Launcher in a separate window.

Pasting results. Nothing looks crazy, but I'm new to KDE side of the house.

Code: Select all

$ plasmawindowed org.kde.plasma.kickoff
org.kde.plasma: invalid fallback path in  ""
org.kde.plasma: unversioned plugin detected, may result in instability
org.kde.plasma: requesting config for "Application Launcher" without a containment!

Tried both of these things. Same effect. Right clicking on any launcher menu item takes about 30 seconds to get the menu, no matter the user or where the launcher sits.

Do you get a "Remove <appname>" action in that menu?

No, the menu contains "Add to Favorites", "Add to Desktop", "Add to Panel", "Add as Launcher", and "Edit Application".

My guess is that the slowdown is related to PackageKit -- could you disable the PackageKit daemon and retry?

I've had PackageKit disabled for ages. For some reason it chooses the moment I'm dnf installing something to check for updates.
