This question already has an answer here:
I am really new to this Linux world and my system is running really slow since after installing Ubuntu 14.04. It is showing some type of error:
low on graphics. cannot detect your screen , graphics and devices.
I am running the OS in low graphics mode and moreover I have to goto boot options every time I switch on my PC and select the low graphic mode option in (Advanced options in Ubuntu) → Recovery mode. How should I make my pc in normal working condition.
sudo lshw -c display
