Ubuntu 14.04: Cannot change screen resolution
Method 1: Disable Unknown Display
Click the Unknown Display Box and below it's on, turn it Off and Apply, Every time you Install Ubuntu for the first Time the Cause is Unknown Display.
Method 2: Changing Display Driver to X.Org
If you encountering Problems but the First Method doesn't Work, Try this Method
Open System Settings
once opened you will see some options, Click Software & Updates
and then Additional Drivers Section. Tick the "Using X.Org X Server" and Apply Changes Once applied Reboot. and Try changing the Resolution.
My Experience
I'm Having Problem with the brightness when NVIDIA Driver is in Use and when trying to Enter a Command for a Solution and rebooted the Brightness is remain the same,So i try changing to X.Org and it Worked!

I know there are many questions with the same topic, but no solution seem to apply to my case... I'm on Ubuntu 14.04 on a Toshiba Satellite L735 laptop. My xrandr output is:
Screen 0: minimum 8 x 8, current 2390 x 768, maximum 8192 x 8192 VGA-0 connected 1024x768+1366+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0*+ 1360x768 60.0 59.8 1152x864 60.0 800x600 72.2 60.3 56.2 680x384 60.0 59.8 640x480 59.9 512x384 60.0 400x300 72.2 320x240 60.1 LVDS-0 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 294mm x 166mm 1366x768 60.0*+ HDMI-0 disconnected (normal left inverted right x axis y axis)
Why don't I have more options for LVDS-0?
I don't seem to be able to Mirror the displays either...
I am using the recommended nvidia driver:
NOTE
It is not a problem with the second screen, but with Ubuntu/Nvidia themselves... because when I am not connected to a second screen, I still cannot change the resolution.
Please help! I need to be able to:
1- Change the resolution on the laptop screen (with or without a second screen associated)
2- Use mirror displays when a second screen is present

hhsadiq about 8 yearsWere you able to solve this using NVIDIA drivers. I don't want to go back to x.org server drivers.
