I inadvertently changed 18.04.2 default display setting from 16x10 (1920x1200) to 16x9 (1920x1080) in Ubuntu's display settings and lost video signal from my desktop install (Intel i3 8th gen NUC, Dell 2415U monitor).



I can USB live boot with video from the NUC. But unable to get HDMI video signal when booting from the NUC's 970EVO SSD.



Any advice is most appreciated.
