I've started my Raspberry Pi Model B without having any monitor plugged. Then I plugged the HDMI monitor, but got no signal. So far I've been able to turn it on by using the command:
But it only turns the monitor on and sets the preferred display mode, while the screen is still blank. I've then been able to reset to low-resolution console by starting Xorg with the command
(which runs in low resolution itself) and then just typed
exit into the terminal.
The problem is that the resulting console is still low-resolution, and the way I got it is far from being elegant.
How can I get the native-resolution console after booting up without monitor, without rebooting?
