[SOLVED] Issues with minimizing KDE windows / kwin

[doktor5000]

I am using Mageia 4 and Mozilla Firefox 24.3. 0. After installation, I noticed that the icons ony the top right corner on the screen to minimize or expand applications are gone. I must close the application completely. Same with Dolphin Manager and other applications. I did more updates to check if there wsa a file or distribution file missing, but it is all current. Any ideas or suggestions would help.

What desktop environment, theme and window manager do you use? Those icons are not related to the programs, but window manager and window decoration/theme.

I'm using KDE. Window decoration is Oxygen. Color scheme is air. Default Mageia splash screen. I use Dolphin file manager. It is the corner of the graphical interface window where you either minimize, expand or close an application or window that is the issue. some work and some don't. I am new to Linux, so if it takes me a while to get the right words or description correct, apologies for that.

Could you take a screenshot please?

window decoration = oxygen
workspace design = custom (but mostly oxygen)
style = oxygen

Here is the snapshot.

Of the 3 buttons on the right side, the right button closes, the middle one maximizes/changes size, the left one minimizes.
What exactly doesn't work, and what does work?

[TartanGargoyle]

None work. I have to go where it says FILE on the left hand side of the Navigation bar, and select QUIT to close it.

Did you do a fresh installation, or use an existing /home partition? Or maybe did you enable 3D desktop via MCC? http://doc.mageia.org/mcc/4/en/content/drak3d.html

[TartanGargoyle]

It was a current existing partition. I updated from mageia 3 to 4 to keep all existing programs and settings. So it was on line.

Can you try if the issue persists with a newly created user?

[TartanGargoyle]

I created a new user, and the issues were not present.

[doktor5000]

Okay, so the issue is caused by existing settings.
You could simply delete the kwin settings and restart kwin by running the following commands as normal user

Code: Select all

find ~/.kde4/share/ -iname "*kwin*" -delete && nohup kwin --replace &

Hi, I had a same problem after Mageia 3 to 4 update. I thought it is related to ATI Catalyst driver as I am using HP4545s with ATI Radeon graphics but here I found it is not. kwin --replace & in startup script resolved it. Thanks.

To repeat it, this is only an ugly workaround. You should still try to find out the underlying cause of it
(conflicting old settings, enabled 3D desktop/compiz etc.) and fix that instead of using workarounds permanently.
