During the last 22 years, I got used to the setting when the XWindow system appeared on one of the "graphical" virtual terminals, mostly on tty6 or tty7.
However, after installing a new Gentoo system with gentoo-kernel, I found out that the XWindow system started to appear in the same tty, where I started it using the startx command, shadowing all that was typed there including the messages from the xorg-server. So, I just wonder: "Is it a bug or a feature?" And where exactly can one configure it?
