Kwin GLES as default window manager in Kubuntu 11.10 and KDE 4.8

Kwin GLES has great performance on my Lenovo Thinkpad X220. It looks more snappy and also the battery last longer.

After upgrading my laptop to KDE 4.8 I was unable to start Kwin GLES as default window manager. The only way was to switch it in console:

kwin_gles --replace &

It's not very comfortable. I found this hint on ArchWiki, and adapt it for Kubuntu:

First, you need kwin_gles installed:

sudo apt-get install kde-window-manager-gles

When it is installed, create new file ...

sudo nano /usr/share/kde4/apps/ksmserver/windowmanagers/kwin_gles.desktop

... with this content:

[Desktop Entry]
Name=KWin GLES
Exec=kwin_gles
TryExec=kwin_gles
X-KDE-WindowManagerConfigure=systemsettings
X-KDE-WindowManagerRestartArgument=--replace

Now you can change the window manager in the system settings: Open System Settings, go to Window Manager, select Use a different window manager: and select KWin GLES.


Next time you start your KDE session, you will be using Kwin GLES!
