I have an Acer TravelMate P648-MG ( with NVIDIA GeForce 940M graphic card). I have installed Ubuntu 20.04 and have been using it for a month without any problem. The last time I was logged in, it was doing an update then I turned my pc off and when I turned it on I got this screen "screen 1" I hit "enter" but it doesn't want to start. I just get a black screen with blinking cursor(now even the cursor disappeared) . I tried to remove ubuntu-desktop and install it again (making sure that it's gnome as I've seen in some answers but didn't work for me) Is there any solution for this problem without having to reinstall the whole OS?
I'm really stuck..Any help would be appreciated
