it seems to be better if I choose XRender instead of
Desktop effects altogether is a bad option because of all the
rendering problems that appear when doing that.
Early yesterday morning I did zypper dup to 12.1 Milestone 5. At first I had
the kernel and virtualbox tabooed as I initially wanted to keep 2.6.39
kernel and nvidia 260.19.44 driver version. After making a backup image I
un-tabooed these and updated to kernel 3.0.0 (what's in Factory). I then
tried both nvidia driver versions 280.13 and 285.03(beta). Desktop effects
in general seemed fine now, except for one last outstanding problem.
The killer mouse and keyboard lag I spoke of before was still present. All
other problems, such as menu pop-ups backgrounds, etc, were vanquished. I
found that the nasty lag also went away if I chose Xrender as the
compositing backend instead of OpenGL under the Advanced tab.
There are 2 files that need to be modified in order for the 260.19.44
drivers to build their kernel module on the 3.0.0 kernel. I just did that
and installed 260.19.44 version. In the Advanced tab I can change back from
Xrender to OpenGL compositing and the lag is no longer present.
If it wasn't for that one last sticky point I would still be using the newer
drivers. The kernel update plus the new drivers did not cause any trouble
with desktop effects at all; just waiting for characters to echo to the
screen and never being quite sure exactly where the mouse was at any given
moment was a show-stopper. Also, I should probably include that killing the
window manager and going to console was also symptom free.
