I have a problem after updating my drivers for the nvidia with the software update programm and at the same time I ticked a box under it saying to use my processor.It asked for a restart to take place and after that the system starts by booting some commands instead of that e letter which was appearing and never opens up really . As soon as I try to press a button on the keyboard or move the mouse goes to suspend mode. Please somebody!
I solved the issue quite easily finally. Opened the terminal with alt+ctrl+f1 and followed the first command to remove all nvidia from the following topic: https://askubuntu.com/questions/206283/how-can-i-uninstall-a-nvidia-driver-completely Thanks everyone for sharing his knowledge -experience!
