You must have manually installed graphics drivers. I always have this issue when updating kernel.

So, reinstall your graphics drivers and run

init 3
sax2 -r -m 0=fglrx

Then, restart window manager by running

init 5

My guess is you updated your kernel as well and your graphics driver needs to be reconfigured for the new kernel. Are you using the official ati driver? If so, did you install it straight from yast or did you download it from the ati website? If you downloaded from the ati website, su into the root account and run fglrx-kernel-build.sh.

Also, if you run startx from the console, some error or other should pop up.

I had just new installed a standerd package suse and didn't install anything else, either the development packages or graphic card driver. I saw that it's recommand "update your system to the newest,and then install the graphic card driver". So I first updated suse first after installed.
And now, I don't know whether my system is installed with all the packages which will be need during installing the graphic card driver, like kernel Source and Kernel Headers.
I think maybe I should try to install the graphic card driver first.

You mentioned that you updated KDE...What version did you update from, and what version did you update to?

[bankyni]

I just run the system's updater and installed all the fixes. The version is opensuse 11.1 KDE 4.1.3 before updated, but I don't know what version I have updated to.

Now I have tried to install the newest driver downloaded from AMD official website, and the KDE GUI started again! But there's a problem that the KWin is just keep crashing. I'll try to put a screen print.

I can even not close the windows now. All the windows title bar are disapear.

Finally, I find the reason why the GUI didn't work! It all because the graphic card driver. The first time I tried to install the driver was in the graphic mode, and it just said install finished but didn't show what went wrong during installing. In fact, the driver didn't install successfully. It is why the KWin kept crashing.
Hopefully, I still can install the GNOME environment. After installed GNOME, I installed all the packages needed during installing griphic card driver. At the end, I installed the driver successfully! now, the system is running well, and the KWin doesn't go crash anymore.

Don't believe the AMD driver says it can support your system with precompiled package. You should just install all the packages follow:
Kernel Source *
Kernel Headers
XFree86-Mesa-libGL
libstdc++
libgcc
XFree86-libs
fontconfig
freetype
zlib
gcc *

* : must be installed
Just check one by one and install the missing packages.
The driver can be compiled automatically when installing by recommand way.
After all, the official driver now is good enough.
