Why doesn't the monitor output anything in Linux console mode?
- by flypen
I install Linux without graphics support. Previously I used a monitor with 720p support. And it can display normally. Now I change to a monitor with 1080p support. I can see BIOS and GRUB info on monitor, and kernel messages in early stages. However, the monitor says that there is no input immediately, and then I can't see anything again. It seems that it happens after something initializes. Is it related to vesafb?

vesafb: scrolling: redraw
