After upgrading my laptop to Ubuntu 18.04.1 and rebooting, I have five options to choose from the cog wheel beside Sign in button,
- Gnome
- Gnome with Xorg
- Ubuntu
- Ubuntu with Wayland
- Unity
And default option was Ubuntu. But after entering the password and sign in button, my laptop froze(Violet Screen).
I forcefully shut down my laptop and chose Gnome and entered password and was able to login. But now if I am clicking on any icon in the Dock Panel my laptop froze again. I was not even able to to open Terminal using keyboard shortcuts. After trying for whole day and after using windows, I logged into Ubuntu again next day and it worked fine in both Gnome and Ubuntu environments. But now again I am unable to use, the problem remains the same. I am using HP-Pavilion with Nvidia Graphic card and Dual Boot with Windows 10. Linux Kernel 4.15.0-33
