Ubuntu not able to see desktop screen

[Testing QA]

I have upgraded some software's and restrated pc.
After that I am getting error "The system is running in low graphics mode".
I am not able to use mouse.
After clicking okay I am getting message as:
"/dev/sda2: clean, ****/******* files, ****/******* blocks"

P.F.A

It is due to wrong version or configuration of graphics driver. You might try reinstalling the graphics driver from tty. Most probably the driver may not be compiled for the current kernel. 
How to solve this depends on the version of OS, kernel and graphics card. Please share the details.
