I tried by many ways to get my graphic card installed to get the correct resolution to my two screens. I tried on ubuntu 16.10 but currently am on 14.04

One is 1920x1080 and the other is 1680x1050

My graphics card is a NVIDIA GT 630.

What I did most recently is:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-367

(I searched and found the right number on NVIDIA website)

sudo reboot

I checked that I used the correct driver :

Ubuntu softwares

But I cannot see the correct resolutions for both my screens in X Server :

The max resolution I got for each screen is 1360*768 !

Here is a screen of the xrandr --query command :

(I also tried to download the .run from nvidia server and install it via Ctrl + Alt + f1 mode but it was unsuccessful to ! I did not succeed either by adding a new resoltuion by hand (with xrandr --addmode methods))

Here is the output of the lspci -v command to show my graphic card :

For those looking for the answer, I finally made it work !

Besides installing nvidia-367, I switched cables between my two screens :

I used the VGA for my Samsung SyncMaster S22B150 and it solved the problem for this one.

I put my ACER AL2216W on the DVI and it still wasn't working for it.

I added the following to my /etc/X11/xorg.conf file :

Section "Monitor"
    Identifier "Monitor0"
    VendorName "ACER"
    ModelName "AL2216W"
    HorizSync 31 - 80
    VertRefresh 56 - 75
EndSection

Section "Screen"
    Identifier "Screen0"
    Device "Device0"
    Monitor "Monitor0"
    DefaultDepth 24
    SubSection "Display"
        Depth 24
        Modes "1680x1050"
    EndSubSection
EndSection

I rebooted, and opening X server, I was able to chose the right resolution. From here, I don't know exactly what I did becasue the resolution wouldn't stay after each reboot, but I know have the following /etc/X11/xorg.conf file :

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0" 0 0
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"

EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24

    Option         "metamodes" "DVI-I-0: 1680x1050_60 +0+0, VGA-0: nvidia-auto-select +1680+0"
    Option         "SLI" "Off"
    Option         "MultiGPU" "Off"
    Option         "BaseMosaic" "off"
    SubSection     "Display"
    Depth       24
    Modes       "1680x1050"
    EndSubSection
EndSection

From here, it wasn't enough, I had to enter the following lines in a shell :

gtf 1680 1050 60

It outputed :

# 1680x1050 @ 60.00 Hz (GTF) hsync: 65.22 kHz; pclk: 147.14 MHz
Modeline "1680x1050_60.00"  147.14  1680 1784 1968 2256  1050 1051 1054 1087  -HSync +Vsync

I used the Modeline and typed in :

xrandr --newmode "1680x1050_60.00"  147.14  1680 1784 1968 2256  1050 1051 1054 1087  -HSync +Vsync
xrandr --addmode DVI-I-0 1680x1050_60.00
xrandr --output DVI-I-0 --mode 1680x1050_60.00 --rate 60

AND IT WAS OK !!

When I reboot, at the login screen, my ACER screen still won't have the good resolution but as soon as I'm logged in, it's ok !

    I'm glad to hear of your success with GT630 after reading so many failures. I might try my Nvidia GT650M + Intel hybrid soon using some of your answer. – WinEunuuchs2Unix Oct 28 '16 at 0:58
