After upgrading to 14.04 I also have this flickering problem again. It seems
that the old line in options.conf:
options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x" NVreg_Mobile=3
NVreg_ModifyDeviceFiles=0
is not read anymore (I found this somewhere in the net and it solved the
issue on 13.
Public bug reported:
As requested in Bug #1310633 I'm opening a new bug.
With a previous version of Ubuntu I already had this flickering. With
additional options for the kernel module I was able to fix the
flickering.

Finally I could not wait and installed the new version of Ubuntu today.

not installed.
But even now after installing it, adding an initramfs hook and creating

Still no success. Freshly installed Ubuntu 14.10 with Nvidia driver

CCSM workaround mentioned above in this thresd still does not solve the
issue.
The system is completely useless with this flickering.
