X-Org problem

[Ott Köstner]

Dear list,

After upgrading Xorg from ports to the latest version
xorg-server-1.6.0,1
xorg-7.4_1

I am experiencing very unpleasant phenomenon, Xorg randomly exiting with message:

Apr 24 15:16:16 ott kernel: pid 7445 (Xorg), uid 0: exited on signal 6
Apr 24 15:16:16 ott kdm-bin[1020]: X server for display :0 terminated unexpectedly

Also, there is a strange behavior with dual-head mode -- when moving cursor from one screen to another, the little white arrow remains on the other screen.

Please help! What might it be? Recompiled probably everything related to Xorg. Using Nvidia driver version
nvidia-driver-96.43.11

With best regards,
Ott Köstner
