- Remote desktop on the CubieTruck
Multiple X sessions ∞
Tested 2009-04-19 on PCLinuxOS 2007.
Assuming you are already in an X session (
\nohup \X :1 >> /dev/null&
Now a new X session begins (session 1).
- session 0 is
control-alt-F7(the original one)
session 1 is
control-alt-F8(the new one)
From your original session, you can force the new one to run commands, like a window manager (for example, Openbox), like so:
DISPLAY=:1 \nohup \openbox >> /dev/null&
Note that some commands have a
-display parameter which you could also use.
- How can I launch a new X session without being forced to switch to it?
How would I remotely shut down an X session?
Make sure that you can
control-alt-backspaceto kill an x-session.
- I don't know how else to exit.
You can also clone your present setup (window manager, startup scripts, etc), like this:
\nohup \startx :1 >> /dev/null&
You can edit your X startup scripts if you wish, and do much fancier things. For me, it's Xsession.
Other possible methods ∞
Several window managers (including cwm(1) and fvwm(1)) offer the ability to change window managers on the fly, without restarting X or any of your applications. Your new window manager replaces your old one, exiting the newly loaded window manager terminates X, it does not return you back to your previous window manager. fvwm(1) allows you to start a different window manager by left clicking on the background ("root window"), chose "(Re)Start", then pick your preferred window manager (however, note that you will need to add your alternative window managers to your .fvwmrc file (the system-wide default is /usr/X11R6/lib/X11/fvwm/.fvwmrc)). cwm(1) allows you to invoke another window manager by hitting Ctrl-Alt-w, and typing in the manager you wish to switch to.
Multiseat - Two users sharing the same X11 desktop ∞
previous failure ∞
- You're presently in an X terminal
- You have access to root
SSH is installed and will work for localhost
- Maybe just
service sshd restart
- Maybe just
- Customize to your needs
# Setup: su - # become root adduser testhost -n -g users adduser testguest -n -g users # Set up passwords (your choice): passwd testhost passwd testguest exit # exit root
The guest can't grab the same Xnest. Damn.
control-alt-F7 to get back to your proper terminal.
DISPLAY=:2 nohup xterm -geometry 80x24+0+0 -exec "$SHELL" -c " ( ;\ cat << HERE_DOCUMENT ;\ #!/bin/bash ;\ DISPLAY=:2 nohup export DISPLAY=ipnumber:2 >> /dev/null& ;\ DISPLAY=:2 nohup Xnest :1 -display :2 -geometry 640x430+0+0 & >> /dev/null& ;\ HERE_DOCUMENT ;\ ) > ~/runme ;\ " >> /dev/null & # switch to session 2 with `control-alt-f9` # type in the password you created for testguest # disable remote access? # xhost - (IP) # xhost + localhost # Teardown: su userdel -r testhost userdel -r testguest service sshd stop exit

Using freenx ∞
An old note:
For faster remote desktop connection in ubuntu - install openssh, freenx server and nxclient. The speed will be amazing fast.
sudo apt-get install ssh
Visit http://www.nomachine.com/download-client-linux.php and download the nxclient for your platform.
For ubuntu you can download the .deb file, right click on it and install.
