I'm having problems started several days ago where my screen turned black after logging into my user. Also, the resolution wasn't right on my logging screen. After trying a few solutions iv'e googled i ended up adding nomodeset on the grub launch option of ubuntu.
For sometime iv'e still had unity running, and i was able to access System settings through the button on the top right corner. when i did and i tried to set the resolution to the correct one, i wasn't able to do that, only one option appeared and the screen showed the word 'laptop' on it (and i'm not using a laptop...).
After trying a few more things online, i ended up with unity crashing on start-up and still my resolution is incorrect. I'm able to surf using google-chrome which i can open using terminal.
please, help me fix this.
