I'm trying the distribution Ubuntu 14.04 and when I start sometimes appears the error 'The System is running in low graphics mode', so I reboot and if I am lucky it will start normally but is annoying be doing that, so what I can do?.
My computer is a Samsung np270e4e-k05mx
Screen: LED HD de 14" (1,366 x 768), antirreflejante
Graphics: Intel® HD 4000
I put the features of the screen because I think is in it the problem.
I'm a beginner on Ubuntu, so i don't know what the problem is, but I tried some of the solutions in other questions, how to reinstall the ubuntu-desktop or sudo apt-get install fglrx, but it didn't work.
