I am having screen display problem on my ubuntu 14.04 LTS OS with I dual boot with Windows 10 recently. The display is "incomplete" or "flaky" at all time even at log in page (example in the picture below):
The missing part keep changing whenever I move my cursor over or highlight them. The situation gets worse when I am running something heavy, installing a software for example.
I am not really sure about the problem but my guess was I have to install Nvidia graphic driver manually. The graphic card in my PC is Nvidia GeForce GTX 745. I tried installing the driver through:
Driver taken from Nvidia website
sudo apt-get install nvidia-current
sudo apt-get install nvidia-current-updates
However, all three methods seem not accepted by my OS where I couldn't even log in after reboot. I have to use Ctrl + Alt + F1 to log in and uninstall them.
Thanks for your time and your helps are very much appreciated.
