I have an Nvidia GeForce 740M graphics card and an Intel Core i5-3337U 1.8Ghz processor in my Asus K56C laptop. I know this issue has happened to many others, but I tried all the solutions I could find and not single one worked for me.

So I tried to install Nvidia driver from Additional Drivers, and after installation and reboot I login and my screen goes black with only the mouse visible. I read some different solutions, but nothing seems to work!

Solutions I tried which didn't work, there is still a black screen after login:
installing nvidia GT 740m driver on Ubuntu 13.10 get Black screen after login!
Blank screen after installing nvidia restricted driver

And some others, but none seems to work, and at this point all I want is anything just so my driver works and I can again use Ubuntu! I also tried manually downloading the driver from the Nvidia website and installing it, but I had the same problem.

It's Asus K56C, Core i5-3337U 1.8Ghz, GT 740m. –  user1880405 Mar 13 '14 at 23:56
Your CPU is an Intel ULV (Ultra-Low Voltage) 3rd generation processor, VERY energy efficient, but maybe there is your problem and you may have to also install bumblebee which is hard to do, so first start off by doing the easy things. In the Dash search for Additional Drivers, click the Additional Drivers icon and the Additional Drivers window will pop up. In the Additional Drivers window it will show what is the Recommended Nvidia graphics driver version for your GPU. –  karel Mar 14 '14 at 0:52
This question Nvidia 520MX on Asus K53SC will give you an idea of what is meant by installing bumblebee discrete/integrated graphics switching application is hard to do. However in Ubuntu 13.10 the bumblebee package is in the Ubuntu Software Center, so it's quite easy to install. –  karel Mar 14 '14 at 1:17
Open a text-only console by using the keyboard shortcut Ctrl+Alt+F1. At the login: prompt type your username and press Enter. At the Password: prompt type your user password and press Enter. Now you're logged in to a text-only console. Remove the driver: either sudo apt-get remove YOUR-NVIDIA-DRIVER or maybe you have installed a different driver that you downloaded: Remove proprietary Nvidia drivers?. sudo shutdown -r now reboots the computer. Ctrl+Alt+F7 exits from the console. –  karel Mar 14 '14 at 8:18
Yes 13.10. I've done what you said and now it works fine! But one thing which never happened before is after login my screen stays black for like 15 seconds before entering desktop. As well as several message boxes to send the error report. Either way, thank you for simple solution. For some reason Nvidia drivers do not work at all for me, I tried all guides on installing them. –  user1880405 Mar 14 '14 at 8:49
