#12106 — switch to a virtual termina logs out my X session

On my kubuntu machine (10.04), if I switch to a virtual terminal, when I 
try to go back to my X session, it's gone.

Can anyone point me to documentation about how virtual terminals are 
related to X sessions now?


An internet search tells me that lots of people like virtual terminals, 
and nobody seems to notice that as of some point in the past, they can't 
get back to their X sessions anymore.  This tells me I must have 
something misconfigured (i.e. configured in a way that wasn't foreseen or 
cared about by the people who made whatever changed that killed virtual 
terminals for me).  But I haven't a clue in what way.

TIA

how are you getting there, and trying to get back?

Has the screensaver cut in while you were 'away' needing the space bar 
to be pressed?

they represent different outputs being sent to the same monitor. They 
can and do exist entirely independently.

Not really. I only use them to stop X to tinker with it. Otherwise I use 
a console in a window.

Indeed. Because they usually can, even if its means stopping and 
starting the display manager

Or are simply nit actually understanding what is happening.

Look at the process tree to see if display manager is still running.

Alt-Ctl-1 and then Alt-Ctl-7

No.

I think it is (don't want to test it right now).  In any case, all the 
other processes of my session are running, until I log in again in xdm.

oh right.  The point is, when I go back to Alt-Ctl-7, I get the xdm - I 
mean kdm welcome screen.  Once I log in, it's a new session.

A likely possibility is that gnome or whoever would grab that and lead me 
- via pam or some such - back to my original session.  But I don't use 
gnome, I use FVWM.

Hmmm.  There's probably a way to configure that, but I wonder if it 
wouldn't just be easier to used xdm ... I wonder what would be involved 
in that.

The next time you are in a virtual console, try hitting the Alt and
left arrow key.  It works for me.

Ctrl Alt F7 never worked for me.  I would get the message:  Restoring
resolver state, and it would hang there.


From Wikipedia:

Usually in Linux (see Linux console), the first six virtual consoles
provide a text terminal with a login prompt to a Unix shell. The
graphical X Window System starts in the seventh virtual console. In
Linux, the user switches between them with the key combination Alt plus
a function key – for example Alt+F1 to access the virtual console
number 1. Alt+Left arrow changes to the previous virtual console and
Alt+Right arrow to the next virtual console.

Okay, my window manager got stuck again today and I was able to check it 
out: when I switch to VT 1, my session is still running, but when I go 
back to F7 (I tried F8, there's nothing there) and I get the welcome 
screen, my session is gone.  This tells me it's not my bash profile who's 
dropping the ball but indeed something with session-management.  Is it a 
kubuntu thing?

I use Fvwm also and I boot to run level 3 and use startx to start a
session.  Effective with FC20, X seems to be running on TTY 1.
So, Alt-Ctl-1 gets me back to my X session.

Unless explicitly directed (by the vtXX commandline switch) Xorg "will pick
the first available Virtual Terminal that it can locate" for it's graphic
session. (See the Xorg(1) manpage).

If you typically start X from virtual terminal 0, X will use vt1 for the
graphics.

If it has login running on it it is not available. I always run startx
on the first VT but X runs on the 7th.  The others are all running
login.

I'm pretty sure something changed around FC 20.

I used to go to 7 for X, now it's on 1.
I didn't change anything on my end.

ON my gnome based system its ctrl alt F8 that gets it back, not 
Ctrl-alt-F7 - that nets me much weirdness.

That something that changed couldn't be systemd, could it?

Makes sense.

That's only partly right.

To switch away from the X Window session you need Alt+Ctl and the VT
screen number; typically 1 or 2.

To switch from a virtual terminal back to the X Window session it's Alt
(no Ctl) and the "screen" number; typically this is 7 or 8.

Returning to X here is either Alt+Ctrl or simply Alt with 7 (or 8).
