That meant that, the system booted normally but there was issue with the login screen. Moment of panic initially for a beginner in Ubuntu, but, I heard the start up sound of Ubuntu. Trying to select the NVIDIA driver worked for me after this.Īfter rebooting, my login screen did not appear. After this, going to Additional Drivers, the driver menu will be reloaded and caches will be update. Its better to change the download server to “Main Server” from “Ubuntu Softwares” tab in Software & Updates. Upon looking it up to various forums, I found out that sometimes the server that is being used to download the drivers causes the issues. In my case, first when I tried to select NVIDIA driver from System Settings > Software & Updates > Additional Drivers it reselect the Nouveau driver (default).

It comes with a default Ubuntu installation, (which my retailer replace with Windows 8.1 and again I replaced that with Ubuntu 14.04 LTS ). I recently got Dell Inspiron 3543 laptop which has I7 processor, 8 GB RAM (replaced the initial 4 GB with 8 GB) and 2 GB dedicated NVIDIA graphics card.
