Description spamfang1199 2010-02-02 23:01:03 UTC

Version:            (using KDE 4.3.4)
Compiler:          gcc 4.3.2-2 
OS:                Linux
Installed from:    Debian testing/unstable Packages

The invert (window) effect does not work. When trying to activate it, a notification appears, saying it cant be activated. This bugs me since KDE 4.1.

I have a Radeon 9600XT with 256 vram and an AthlonXP 1800+ with 2gb ram.

Here are the relevant parts of my xorg.conf:

Please go to System Settings -> Desktop -> Advanced, enable direct rendering then restart KWin from a terminal/krunner with:

KWIN_DIRECT_GL=1 kwin --replace &

Hopefully this will give you pixel shader support in fglrx which in turn will allow you to use the invert effect.

Direct rendering was activated all the time. But I turned it off and on again to see, whether your tips work. Unfortunately, when i enter "KWIN_DIRECT_GL=1 kwin --replace &" in a console, my window decorations with the buttons for closing, maximizing & co. vanish. I cannot use the desktop anymore, cannot switch between applications, as everything seems frozen. So i have to restart X (ctrl+alt+backspace). "Invert" still wont work.
