KDE - Cube desktop query

[Steve]

I have installed Qubes 3.2 and changed the desktop manager to KDE , specifically to get the Cube desktop.

I have gone into the KDE settings and enabled the cube effect however I can;t get it to appear, any suggestions

thx

I am using an Nvidia graphics card , do I need to install the nvidia graphics driver to get the "cube" to animate ? thx

You do if it isn't supported by nouveau 3D mode, most of the newer
nvidia devices make open source drivers like nouveau impossible...

Nvidia is a shitty company to buy from if you want stuff to work the
first time and all the time, as they deliberately break linux features
to try and force people to use windows or buy a card from their
overpriced quadro line.

I am fortunate to have a NVIDIA Quadro K5000M with 4 GB dedicated GDDR5 video memory which is supported by SuSE Linux Enterprise Desktop 11 & Red Hat Enterprise Linux 6.x so I'm assuming I can get drivers that work with Qubes (Fedora).

I did lspci and found that I am running VGA compatible controller: NVIDIA Corporation GK104GLM (Quadro K5000M)

Do I need to change this driver to get the KDE Cube working ?

I should have researched more before posting ! I have now found out that the Nouveau drivers do not support this particular Nvidia card. I did however, find a specific NVIDIA driver that does and I guess provides the necessary 3D capability. I will research how to install in Qubes and report back at some point
