I want to start an Xorg server (which should only feature a minimal
xterm terminal emulator from a newly created "pristine"
tty). I have thought this to be as simple as issuing a
xinit or maybe a
startx however both have failed me. Therefore the question:
How to manually run/init/start a Xorg server on a different VT/TTY?
Longer background story to the question at hand:
This is the backgroud and what I have tried already:
man openvt I was able to run a shell on a newly created
vt, cannot tell precisly the different vt<>tty) like this:
$> sudo openvt -s /bin/bash
-s of causes the direct switch to that new tty/vt
on that new tty I wanted to manually start a
Xorg server which according to
man xinit should start with a minimal
xterm application. On the new shell on the switched to tty I (created via
openvt) I hence issues this command:
$> su -c 'xinit xterm -display :4 -- :4' - mahr &>/tmp/output
and I receive this output
$> cat /tmp/output X.Org X Server 1.19.6 Release Date: 2017-12-20 X Protocol Version 11, Revision 0 Build Operating System: Linux 4.4.0-148-generic x86_64 Ubuntu Current Operating System: Linux scitech 4.15.0-70-generic #79-Ubuntu SMP Tue Nov 12 10:36:11 UTC 2019 x86_64 Kernel command line: BOOT_IMAGE=/vmlinuz-4.15.0-70-generic root=/dev/mapper/ubuntu--vg-root ro Build Date: 03 June 2019 08:10:35AM xorg-server 2:1.19.6-1ubuntu4.3 (For technical support please see http://www.ubuntu.com/support) Current version of pixman: 0.34.0 Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.
