I am really new to the Linux world. My system is running really slow since after installing Ubuntu 14.04. It is showing some type of error:

The system is running in low graphics mode.
Cannot detect your screen, graphics and devices.

I am running the OS in low graphics mode and I have to go to boot options every time I switch on my PC and select the low graphics mode option in Advanced options for Ubuntu → Recovery mode.

How can I get my system working normally?

sudo lshw -c display

  • Open terminal Ctrl+Alt+t, then run sudo lshw -c display. Add its output to the question (BTW, use that small edit under the question) – user.dz Jun 10 '14 at 16:05

Install the accelerated nVidia Graphics driver xserver-xorg-video-nouveau.

sudo apt-get install xserver-xorg-video-nouveau
