Public bug reported: I am using Ubuntu 16.04 LTS
Recently I have been facing problem with computer graphics. Sometimes while working, the system freezes and when the system resumes working a pop-up window appears stating that "An error occurred", and in the details of the error there is problem with Xorg. Today, after powering on the system, a message appeared saying:- "The system is running in low-graphics mode. You screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself". Using a solution from askubuntu forum, I did the following:- 1) Pressed Ctrl + Alt + F1 2) Logged in with my credentials 3) Ran the following commands: $ sudo apt-get install --reinstall ubuntu-desktop $ sudo reboot This helped me open the system. Now, I checked whether the graphics driver is installed or not. So, I went to Settings > Software & Updates > Additional drivers. But, no driver is detected. So, I guess that there no graphics driver installed on my system. After that, I tried the following solution, but the terminal says that requirement already satisfied:- https://askubuntu.com/a/183170 Please help me resolve the issue.
