No XServer after Kernel-Update and reinstall of GFX-Drivers

[Achmed]

X starts when configured without loading the GLX-Module.

I get the following errors ans warnings in the log-file:

(WW) xf86OpenConsole: setpgid failed: Operation not permitted
(WW) xf86OpenConsole: setsid failed: Operation not permitted

(EE) NVIDIA(0): Failed to initialize the GLX module; please check in your X
(EE) NVIDIA(0):     log file that the GLX module has been loaded in your X
(EE) NVIDIA(0):     server, and that the module is the NVIDIA GLX module.  If
(EE) NVIDIA(0):     you continue to encounter problems, Please try
(EE) NVIDIA(0):     reinstalling the NVIDIA driver.

(WW) NVIDIA(GPU-0): Unable to read EDID for display device CRT-0

(EE) Error loading keymap /var/lib/xkb/server-0.xkm

Do not know, what to do now.
I installed the drivers (different versions) many times, and made a lot of changes the xorg.conf.

I need to see a bug report that captures this problem.
