I bought my laptop Windows pre-installed. After deleting Windows I didn't disable the UEFI boot from BIOS (doesn't exits any more). So I installed Ubuntu 15.04 including UEFI boot partition. Everything was fine but after upgrading to 16.04, my Nvidia driver is not working any more. It's stuck on black screen.
After googling, I found out that black screen can be fixed by disabling the UEFI boot but in my situation I cannot disable UEFI. So is there any other way that I can use my Nvidia driver?
Note: I have already tried nomodeset option. It didn't help.
