I think we have encountered similar problems, and because of the
instability with
the rt-kernel we have been using the desktop kernel. The setup
consists of nVidia GeForce 8800GTX
and a Core 2 Quad and it is connected to 30 inch Dell monitor (with
2560x1600 resolution).
It used to be a huge problem for me (as I make music as a hobby) and I
also use the X-plane flight simulator on that
machine (which means that not using 3D acceleration is not an option).
I finally gave up half-way and have ever since been producing my music
on Mac with Logic Studio, I only occasionally
may use some sounds from the Ubuntu machine. I really hope the real
time kernel gets more stable with nVidia in the
future. I have encountered this instability from the times I used
Agnula (long time ago) and it hasn't completely got stable
even in the latest versions of Ubuntu it seems.
