Re: xorg7.4 + nvidia driver: blank tty after killing X or restarting kdm [SOLVED]
Had some progress on the issue.
It's related to having a double screen with Xinerama.
If I change my xorg.conf to have only a single screen, my tty1-6 don't go blank anymore.
So that I might well have been posting on the wrong forums in fact... Because of course, when I switch to the nv drivers, I don't get the xinerama double screen, which somehow sorts out problem... Then if I use only a single screen with the nvidia drivers, I don't lose my tty displays either.
So far looks more like a xinerama problem.
EDIT: I got this sorted out finally. Using the built-in xinerama from the nvidia driver (TwinView option) solved the issue.
