The system is running in low-graphics mode
Your screen, graphics cards, and input device settings could not be detected correctly. You will need to configure these yourself.
I solved this problem by reinstalling ubuntu-desktop.
When the message that “your system is running in low-graphics mode” appears, press Ctrl+Alt+F2, then login with your credentials
Then type below commands
# sudo apt-get update # sudo apt-get remove ubuntu-desktop # sudo apt-get install ubuntu-desktop # sudo shutdown -r now
It should work after reboot … Else try the below option
Solution 2 :
sudo apt-get install gdm sudo service gdm restart
It should work after reboot… 🙂
To reconfigure gdm type
# sudo dpkg -reconfigure gdm
