<br>
I just gave a try to the Alpha 2 live CD and had to notice that compositing is<br>
not enabled by default. I think this is a very bad choice as you don't allow<br>
users to experience the full chances of Kubuntu. This results in the in<br>
general bad screenshots in media as people try in virtual machines (e.g. [1]).<br>
I would appreciate if this default could be changed.<br>
<br>
The system I tested on is perfectly capable of running OpenGL based desktop<br>
effects (after all it's one of my development systems) and pressing<br>
Alt+Shift+F12 enabled Desktop Effects successfully in the live system.<br>
<br>
I can only assume that Compositing is disabled by default because it used to<br>
be problematic especially with NVIDIA on live systems. This is no longer the<br>
case. For one thing the drivers work properly and KWin has a wonderful driver<br>
feature detection and can enable features based on driver and GPU. Also there<br>
is nothing to fear even if the driver is broken. KWin disables Compositing<br>
automatically.<br>
<br>
I have not heard of a real problem like an unusable desktop due to Compositing<br>
in years.<br>
<br>
An additional note: I checked which Qt graphicssystem is used on the live CD<br>
for KWin and it's native. That is not Qt's default and a pretty bad default<br>
for KWin, we prefer to have the raster system.<br>
<br>
If you have any questions please let me know and I am happy to answer them.<br>
