How to Connect Laptop to Analog Tv Using Vga

I'm trying to connect my laptop (Acer Aspire 5315 having Ubuntu 13.04) to Samsung LCD HDTV. I connected the VGA cable; one end on my laptop VGA socket & the other on the TV VGA socket. But when I boot my laptop, nothing appears on the TV as well as laptop. On laptop directly the login screen appears.

My intention is to get the display on the TV. For this I had googled & came across really same question that I mentioned above. But those threads couldn't resolve my issue.

I've a few doubts.

1) While googling, I came across a solution that says to install NVIDIA graphics driver. Now whether this will work for me as the below command shows that my graphic card is not NVIDIA?

          ravbholua@ravbholua-Aspire-5315:~$ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 03) ravbholua@ravbholua-Aspire-5315:~$

In other words, will NVIDIA graphic driver work for all systems irrespective of the graphic card the system has?

2) In google, I found many had given the solution to install the NVIDIA driver via 'Additional drivers' tab as shown below. But in my system there isn't any driver listed!!

So, I will try to install via CLI. I will follow the Dedoimedo site also for this. (I'm assuming the the NVIDIA driver will work for me)

EDIT#1

I tried changing the settings on the display application under System Settings but I couldn't get the display on the LCD TV. I checked the sources available on the TV but the 'PC' option was disabled.

EDIT#2

This edit is w.r.t. the answer posted by @mo_roodi.

I installed the Intel Linux Graphics Drivers from the link he had in his answer. I hope I did it rightly. I installed the Linux Graphic Installer. Then I opened the application & a window popped up named "Intel Driver Manager". Then it upgraded the system. Below I answer to his questions:

1) Yes everything is fine on the laptop screen.

2) I haven't connected ever my laptop to any external display. This is the 1st time I'm connecting to SAMSUNG LCD TV.

3) I haven't connected the TV via PC connection with any external device.

4) I can't say regarding the dual-head capability of the graphics card.

5) I can't say yet whether the VGA cable is O.K. or not. But I did something to test it. Using a multimeter, I checked the continuity. It's a 15 pin VGA connector. I put one probe on one of the pins & the other on the external surrounding metal (trapezoidal in shape) of the same plug (connecter). And it showed continuity!! Does it seem to be a problem? This means the pin & the outer metal boundary is short. Also I found that a pin on one plug was in "continuity" with the outer boundary of the other plug at other end of the cable. Is it really like this!! In RCA cable, it means defective cable. Still, I will try to check this cable at some other place.

I ran

          $ xrandr -q  Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192 LVDS1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 331mm x 207mm    1280x800       60.0 +    1024x768       60.0*     800x600        60.3     56.2      640x480        59.9   VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm    1024x768       60.0*     800x600        60.3     56.2      848x480        60.0      640x480        59.9   TV1 unknown connection (normal left inverted right x axis y axis)    848x480        59.9 +    640x480        59.9 +    1024x768       59.9      800x600        59.9

One point I would like to share. After connecting my laptop with TV via cable, my TV has the PC input option still disabled. Is it that the option should have become enabled after connecting the cable & booting the laptop?

I had checked a youtube video. In that the guy showed how he connected his TV with laptop. There after connecting via cable & booting, he clicked on 'source' button on TV & selected 'PC input'. He was able to select that because it was enabled for him. Still he wasn't getting the display on TV. Then he change the resolution under 'display' menu in his laptop & then it worked.

EDIT#3

Just attaching below the photo of my TV showing that only 1st 2 options (TV & AV) are enabled. 'PC' input is disabled. enter image description here
