I have a dual boot laptop with Windows 10 and Ubuntu 18.04. They have been working fine for some time now. Last night I had left the laptop on all night to download some big files. Now it is stuck at this black screen which appears after the loading screen.
I tried to shutdown and boot into recovery mode. I couldn't find any errors, but I also don't know what to look for.
Edit: I have a Dell Inspiron 15, i3 3rd gen, 4gb ram, dual boot with windows 10 and Ubuntu 18.04, no gpu. This happened after the laptop shutdown due to low power. I have been using Ubuntu for some time. The same screen came a few times before during boot up but passed soon enough. I tried the nomodeset setting but it didn't work.
