I've used your .config. I only changed CPU from AMD to Intel Core 2, as |
| 38 |
well as the SATA and network drivers. Same problems. |
| 39 |
|

So it's not a kernel configuration problem. |
| 41 |
|
| 42 |
And btw, no matter how I configure the kernel, Con's scheduler always |
| 43 |
results in a smooth and fluid composited GUI. Bte, are you even using |
| 44 |
OpenGL compositing or are you just talking random stuff? :P |
