Difficulty enabling OpenGL in oS 12.3

English Virtualization
1

Hi all,
I am new with openSUSE and I just installed v 12.3 on my VMware virtual machine. I’m having trouble enabling OpenGL.
I tried using the KDE desktop in System Settings -> Desktop Effects.

Enabling effects which require OpenGL generates an error which says: “## desktop effects could not be loaded”, of effects which require OpenGL. However, when I set the compositing type to OpenGL it says: “Failed to activate desktop effects using the given configuration options. Settings will be reverted to their previous values. Check your X configuration. You may also consider changing advanced options, especially changing the compositing type.”

Below are screenshots of my OpenGL configuration and graphical information as well:

When I see this I know that I must reinstall the video driver if I have elected to use the proprietary one. For VirtualBox, it means I must reinstall the extension pack. For cases where no proprietary video driver is being used, it may be time to try a new kernel version. Generally, enabling this and seeing the error means that OpenGL has not been enabled and will not become enabled no matter how many times you try. In VMWare, if there is something like an extension pack of VirtualBox, I would reload it. In every case, it does not hurt to to try a newer kernel to see if that helps.

I am going to close this message thread for 10 minutes and them move it to the VM forum, so hold off on any other replies until that has been done.

Thank You,

Maybe this would help you?

After going through the messages, there was the suggestion to run the terminal command:

KWIN_COMPOSE=O2 kwin --graphicssystem raster --replace &

It was not clear if you only needed to do this once or on each restart of KDE, but this should allow the VMWare video driver to run OpenGL.

Thank You,

This would have to be done after each login.
But you could add “export KWIN_COMPOSE=O2” to your bash profile.

Or create a script in ~/.kde4/env/ with the following content:

#!/bin/sh
export KWIN_COMPOSE=O2

You have to set the executable flag on the file.
This would then be executed automatically by KDE during the login.
(See http://forum.kde.org/viewtopic.php?f=111&t=109963#p258858 and the following post)

And you should set the Qt graphics system to “Raster” in the Desktop Effects settings (first picture in your first post).

Thanks very much. It worked just great!!
Everything now works as I was hoping it would.
