I am having trouble getting my desktop cube to work. Whenever I go to here:

it's set in system settings -> desktop effects -> all effects -> desktop cube -> click wrench -> activation

I get the error desktop cube effects require opengl.

I saw someone mention this.

"System Settings > Desktop effects > advanced > Compositing type" is set to OpenGL.
http://ubuntuforums.org/showthread.php?t=2067328

Every time I change the Compositing type to OpenGL. I hit apply and accept changes. When I open that dialog back up I see it keeps getting reset back to Xrender.

did it ever? do other effects work?

what is:

Code: Select all

glxinfo | grep OpenGL

Is this good?

it seems it may work and it seems you need to set environmental variable KWIN_COMPOSE=O and then restart Kwin

guessing something like

Code: Select all

export KWIN_COMPOSE=O
kwin --replace

in future please note you're running a VM when querying about Kwin issues

I'm not using a VM. Not sure it says that. Do you think it doesn't like my video card because it is fairly new?

the glxinfo said VMware so I'm confused

what gpu and drivers are you using ?

Not familiar with Intel video but latest chips (Haswell) should (per reviews) be supported by current Intel drivers

what version of the Intel drivers? should be package fx86-video-intel or similar

what distro and which version?

If those packages are installed, please also check for the presence of a /etc/X11/xorg.conf file - and if it exists, move it elsewhere.

@COKEDUDE

"Gallium 0.4 on llvmpipe" is a software rasterizer, ie. you're not using HW accelerated OpenGL but a fallback software emulation.
Install "intel-dri" and restart X11
