  • is it possible to start vnc session without installing desktop environment?
  • if no, provide stand-alone vnc server installation similar to SSH.

note: right now i am using twm on debian bullseye (userland app). twm is enough for me.

first requseted on #401 but the focus of the issue shifted to vnc start issue

twm: https://en.wikipedia.org/wiki/Twm

  • Yes its possible to start vnc without desktop, it will show a blank screen, and if you run a graphical app the gui will run on the vnc server.
  • I make an experimental script just for you, this might be added as a new feature in the future, but no guarantee.
    Command: wget https://github.com/EXALAB/Anlinux-Resources/raw/master/Experimental/vncserver/apt/de-apt-vnc.sh && bash de-apt-vnc.sh

This setup currently include startx in xstartup, if you encountered any issue, please report it here.

@exalab999 thank you for considering my request. i assume
the command should after ./start-debian.sh. i
will report after 18th, november about success or
failure of the script...

@exalab999

installed successfully, but it seems to have an issue.

  • installed debian
  • edited /start-debian.sh
  • enable sdcard access
  • copied sources.list
  • ./start-debian.sh
  • # apt update && apt full-upgrade
  • installed vnc server
    ** error: Would you like to enter a view-only password (y/n)? n xauth: file /root/.Xauthority does not exist New 'remote-desktop' desktop is localhost:1 Starting applications specified in /root/.vnc/xstartup Log file is /root/.vnc/localhost:1.log
  • i am able to access using multivnc
  • screenshot of vnc session
    vnc
  • webarchive —localhost:1.log

localhost:1.log

  • it seems twm is not installed by default in debian installation.....

@jindam-vani

It was designed to be blank since it only contain vnc server.

If you need it to work with twn, simply install twm using

apt install twm

then stop the vncserver:

vncserver-stop

and restart it:

vncserver-start

This should be able to run twm when vnc started, if this doesn't work, try to edit ~/.vnc/xstartup file and replace startx to the command that start twm.

  • i am able to use twm only after installing xorg: apt install xorg
  • i hope you will remove experimental & add this to "window manager"?
exalab999 commented

To @jindam-vani and everyone who come here to search how to install TWM, this will not be added as new feature, but a script has been added to install twm on apt based distro:

wget https://github.com/EXALAB/Anlinux-Resources/raw/master/Beta/window_manager/apt/TWM/de-apt-twm.sh && bash de-apt-twm.sh

This script is for apt based distro only, and it will NOT be removed from repo in the future.

@jindam-vani Sorry my bad, fixed it now and should work, it was a typo in the script.

Changed from windowmanager to window_manager
