I have one graphics card with 2 OUTPUT ports: VGA and HDMI and 2 led monitors.
On the 1st monitor, the HDMI one, I use the graphical environment (Unity/KDE/Gnome etc).
Using NVidiaSettings, I can use both monitors side by side with different windows on each one but only on graphical mode, if I hit ctrl+shift+f1 both will be on text mode at vt1 like a cloned identical view.
I would like that on the VGA connected monitor (the 2nd), I could keep vt1 text terminal (ctrl+shift+F1) permanently opened, even w/o login.
Why? because if kernel freezes/panics/somethingWeirdHappen where I cant use the keyboard neither mouse, the only place I can at least see some kind of log is there, at vt1. When the worst happens, such log will not be stored on the HD, so I have to get my smartphone and photograph it to track the problem.
Of course any out-of-the-box alternatives to grab that special critical log info are mostly welcome!!!
I know it is not being stored because one thing I saw on that log was "dm_mirror" and this found nothing after reboot:
grep "dm_mirror" /var/log/* -a 2>/dev/null
How I saw it? I know the freeze may happen after about 12mins after the boot and the graphical login shows up. So I switch in about 10min to vt1 and wait. I think it is related to lvm mirror legs/logs but that would be another topic
