Running nvidia-390 or -396 on Ubuntu 18.04 (Bionic) and 17.10 on a Windows dual boot machine I would sometimes encounter a blank screen after grub, especially when rebooting from Windows and attempting to boot to linux.

I tried a lot of things to investigate this, the only signal that something was wrong i could find is that the grub screen would have a 30 second timeout instead of a 10 second timeout seemingly every time the error was due to occur. Looking into that it looks like Grub has a ‘recordfail’ mode that causes this long timeout, I don’t know what else it does but it would appear that’s what was breaking my boot.

Edit /etc/grub.d/00_headerand find a line setting recordfail=1 (enabling recordfail) — change this to ‘0’ and run update-gruband profit.

If anyone discovers just what recordfail was doing to bork this up I’d be very interested to hear.
