It looks like there have been major changes in
kernel configuration from beta2 to beta3, as
nvidia driver can no longer be installed,
even with whole of kernel development installed.

Nvidia install script complains about missing headers.
Same driver installed flawlessly on 10.2 beta2.
After some fiddling with on-line updates and various
kernels, I did finally install the nvidia driver.
But when I tried to configure the resolution,
the sax2 crashes on testing it. So it can't be configured.

Please don't say that you are not responsible for
third party drivers. Linux desktop is completely
crippled without proper 3D acceleration.
We don't use Linux to run YAST, we use it to run
applications.

I have installeed 32 bit DVD version.
My graphics card: Nvidia 8800GTS 320 MB
My monitor: HP LP3065 (on the market for 8 months,
not listed among HP monitors, I had to configure it
as DELL 3007WFP to make it work)
Resolution: 2560x1600 (also not listed as LCD, or VESA WQXGA).
Apparently, DPMS does not report anything (not the
size not the resolution).

I can't provide any logs and stuff since I have no more
time to spend on this, and have deleted the whole 10.3 beta3
and installed 10.3 beta2, which works.
I can't play the "need more data" ping pong game.
You must have some Nvidia card somewhere, just try it.
