Framani You forgot about one package, the -common
package. It's needed as well.
sudo eopkg it nvidia-developer-driver-current nvidia-developer-driver-32bit nvidia-developer-driver-common
To go back to regular Nvidia drivers:
sudo eopkg it nvidia-glx-driver-current nvidia-glx-driver-32bit nvidia-glx-driver-common
As to hibernation, how big is your Swap partition? For hibernation / sleep to function correctly (I don't use it personally) your Swap partition should be as big in size as your RAM. If your Swap partition is too small, these functions won't work properly.
