Bug 391857

That notification should walk you through producing a backtrace and filing a crash bug. Can you do that, or at least attach the backtrace here?

It says "ksmserver-logout-greeter does not provide a bug reporting address"

In the "developer information" tab:

Application: ksmserver-logout-greeter (ksmserver-logout-greeter), signal: Aborted

sorry for replying late

If you are sure the nvidia OpenGL drivers and its kernel modules are installed correctly, and this still happens after a reboot, please report this issue directly to nvidia developers via https://devtalk.nvidia.com/default/topic/522835/linux/if-you-have-a-problem-please-read-this-first/
