after upgrading my machine to 18.04 from 16.04 I noticed that my Nvidia driver is no longer installed and after I reinstalled the driver I'm getting a black screen I've got such a problem before and fixed it with manually installing the Nvidia driver instead of using autoinstall or apt-get install Nvidia (number goes here). I've tried all the method of installation mentioned here and read almost all topic about this problem on askubuntu, its almost 2 weeks now and I'm unable to find a solution to this problem

edit i fixed the problem by updating the kernel
i've spent 3 weeks now with this and the problem was the grub boot loader needed to be updated after the linux-header update i used update-grub every time but i fail to notice that the main grub boot loader was on another distro so i needed to update that grub and that fixed my problem. all thanks to @BarBar1234
