LinuxQuestions.org - amd drivers or kde fail ??

Hello,
for a couple of days I'm fighting with my slacky. Now I unable to start the KDE (startx), only startxfce4 work for me.
The issue I thougt was with the semi useless amd drivers when installed them I installed fglrx-9.012-x86_64-1.tgz (generated from the script with option --buildpkg).
When I run the tests command I received:

Code:

bash-4.2# fglrxinfo 

display: :0.0  screen: 0

OpenGL vendor string: Advanced Micro Devices, Inc.

OpenGL renderer string: AMD Radeon HD 7700 Series

OpenGL version string: 4.2.12002 Compatibility Profile Context 9.012

bash-4.2#

Also when I execute:

Code:

fgl_glxgears

The animation is started successful.

Only startx seems not working!
When I execute startx the /var/log/Xorg.0.log shows:

Code:

Current version of pixman: 0.26.2
