[SOLVED] Unable to maximise, minimise and close windows.

[kirkkaf13]

Hi all,

I have turned my computer today and the top of any application is missing, I can no longer minimize, maximize and close an application the standard way.



Any ideas how I can get this back?

For a single window you can try the following:

1. click on the window to make it active
2. after pressing 'ALT+F3' a menu should pop up
3. uncheck the option "more actions -> no border"

The menu entries are translated from German (Weitere Aktionen -> Keine Umrandung).

This can happen if the window manager crashes while the X-server is still running. So, you could also try to "repair" your running session:

1. press 'STRG+ALT+F4' to switch to a console
2. log in as the same user who is running the faulty KDE session
3. check whether kwin is running:

Code: Select all

ps x | grep kwin

4. if kwin is not running you may try to start it:

Code: Select all

export DISPLAY=:0
kwin &

5. log out from the console and return to your KDE session

Occasionally I had the same problem some time ago. If nothing else helped I used a lazy but time consuming option: rebooting the system...

Thanks for your support but this has not resolved my problem.

I rebooted my machine which seemed to work untill I try and resize an application and the window manager crashes every time.

Could it be that you have enabled 3D desktop in Mageia Control Center? http://doc.mageia.org/mcc/3/en/content/drak3d.html
Please disable that and try again.

Otherwise please try to disable the KDE desktop effects, can be done via either Shift+Alt+F12
or via systemsettings -> desktop effects -> disable desktop effects on startup.


Apart from that, what graphics card and driver do you use? This can be queried via

Code: Select all

lspcidrake -v | grep VGA

You are correct, I forgot I enabled this feature after reading through the manual I wanted to try it out. After turning this off the window manager no longer crashes when resizing the window.

Thank you.
