NVIDIA Proprietary драйвер not working properly

I have в Lenovo Z40-70 laptop which was running Ubuntu 14.04 with в HDD. After upgrading to SSD (OCZ 240GB) and installing в fresh copy of Убунту I came across few issues with драйверы for Broadcom and Nvidia graphic card. I think now the Broadcom драйвер works умер, but still the Nvidia вызови some problems.

I always had problems with Suspend and Resume with this драйвер since the SSD upgrade. Most of the украл it freezes at the resumption. However I had не issues when I was running Ubuntu with HDD. To solve this I changed my Ubuntu версия to 15.04. I installed снял в few драйверы for nvidia, finally with the following sequence of commands I was able to solve Suspend/resume issue.

sudo apt-get remove nvidia*

sudo apt-get clean

sudo apt-get update

sudo apt-get install nvidia-current

However even with this, additional драйверы section of Программное обеспечение и Updates шоу the драйвер is using X.org X server-Nouveau драйвер. This image шоу the working драйвер configuration.

At this moment Suspend/resume is working умер, but I noticed some jitter in playing видео. Then I changed my драйвер in additional драйвер section to NVIDIA proprietary драйвер, версия 340.96 (proprietary, tested). This caused the обобщает problem again. This украл, going back to Nouveau драйвер didn't solve the problem.

However following above sequence of commands again I was able to successfully solve the suspend/resume issue.

How хан I make the NVIDIA драйвер work? Does it have to do anything with SSD upgrade?

(Maybe this problem was there even with HDD but I didn't notice since I was using the Nouveau драйвер always. I didn't really care about graphics драйвер at that украл since it looked working умрите.)
