Name Acer Aspire 5738 and
Processor Core2Duo T6400, Centrino 1 technology(2.0 GHz, 800MHz FSB)
Screen 15.6, 1366×768, 16:9 HD(5738);
RAM 4GB DDR3
HDD 320 GB
Optical Drive DVD-RW/Multirecorder
Graphics Intel GMA 4500MHD

An Intel GMA 4500MHD on 11.1 ? I don’t think that will work.

If you read what the think wiki site has to say on the Intel GMA 4500MHD:

KMS (Kernel Mode Setting) is a recent development, and requires that you have at least kernel 2.6.31 and Intel Xorg driver version 2.8. But newer is better. With the 2.6.32 kernel and Intel Xorg driver 2.9 you can expect full functionality including external displays and 3D acceleration.

OpenSUSE-11.1 has the 2.6.27 kernel. That is far from the 2.6.31 kernel.

So you will need at least a 2.6.31 kernel to have partial Linux support, and you only get the 2.6.31 with openSUSE-11.2.

Now for better support you will need to the 2.6.32 kernel, and to get at least that you will need openSUSE-11.3 (which will have the 2.6.34) when it is released in mid-July.
