I installed Ubuntu 14.04.1 along side my Windows 7 operating system today. My Windows Partition works perfectly fine, the GRUB menu works perfectly fine, and I've installed any updates for Ubuntu that were present after install. However I cannot get Ubuntu to display in my native resolution of 1920 x 1080. I am only given two options for resolution in the settings, 800 x 600 and 1024 x 768. My graphics card is a nVidia Geforce 750Ti that is connected to my monitor via HDMI.
I've Googled this problem extensively and ultimately decided to try and update my graphics card driver. I downloaded the correct driver from nVidia's website and followed their install instructions. However I cannot get the driver to install. When I attempt to install the graphics driver I get an error message saying I'm running an X server.
I Googled how to disable the X server and I've tried numerous commands from killall x
to sudo service lightdm stop
. Neither of this worked. I either receive a message stating that no instance of X is running, or in the case with stopping lightdm, my entire screen goes black and I'm unable to do anything until I reboot my computer.
Any advice on what to do?
