Sure. This machine is running two X servers as me. As I don't want my
.xsession-errors files to be interleaved, I made one small change to
a system configuration file. In /etc/X11/Xsession I added the line
ERRFILE=$HOME/.xsession-errors-$(/bin/date +%Y%m%d%H%M%S)
but it does mean that I have to sweep them up. I had thought about
distinguishing them by the VC they started on, but haven't got
round to it. Everything else that requires distinguishing uses
$DISPLAY.

Perhaps this is all to do with your DM. I use startx, and since
stretch the Xserver runs "on top of" the VC that started it, and
as the user, not root. In the past, Xservers ran as root on VC7,
VC8, …

Different window managers and desktop configurations. But that's not
the point. It makes no sense to me *not* to be able to do it. It would
be like going back to non-reentrant code when ten instances of emacs
sessions would mean ten executables tying up memory.
