how to run teamviewer in headless mode inside an ubuntu x86_64 docker image

marietto2008

Hello to everyone.

I'm using the jetson nano with ubuntu 18.04 as host os and I would like to run teamviewer. I tried to install the armhf package for the raspberry and after some experiment I gave up because tw does not work in this way. Then I created a docker image with ubuntu focal x86_64 and I have installed teamviewer i386 and I have installed the xorg video dummy :

$ sudo apt-get install xserver-xorg-video-dummy

then I have enabled the daemon,as u can see :

root@3a9d3758f01f:/etc/default# ps ax

 PID TTY     STAT  TIME COMMAND

   1 pts/0   Ssl   0:00 /usr/bin/qemu-x86_64-static /bin/bash

 381 ?       Sl    0:10 /usr/bin/qemu-i386-static /opt/teamviewer/tv_bin/teamviewerd -d

now,following this tutorial : https://thilinamad.medium.com/remote-desktop-to-ubuntu-instance-with-no-gui-f98566adb53e

I've created a new xorg.conf file with this content inside :

# This xorg configuration file is meant to be used
# to start a dummy X11 server.
# For details, please see:
# https://www.xpra.org/xorg.conf
 
# Here we setup a Virtual Display of 1600x900 pixels
 
Section "Device"
        Identifier  "Configured Video Device"
        Driver      "dummy"
        #VideoRam 4096000
        #VideoRam 256000
        VideoRam    16384
EndSection
 
Section "Monitor"
        Identifier  "Configured Monitor"

        Modeline "1600x900" 33.92 1600 1632 1760 1792 900 921 924 946
EndSection
 
Section "Screen"
        Identifier  "Default Screen"
        Monitor     "Configured Monitor"
        Device      "Configured Video Device"
        DefaultDepth 24
        SubSection "Display"
                 Viewport 0 0
                 Depth 24
                 Virtual 1600 900
        EndSubSection
EndSection

probably to do that it's not enough,because I'm not able to configure tw. Infact it gives this error :

root@3a9d3758f01f:/# teamviewer license accept

The framebuffer console seems to be unavailable or has the wrong format. Please make sure that       

/dev/fb0 is accessible and it is configured to 32-bit depth.

now.according with this thread :

https://community.teamviewer.com/English/discussion/9964/teamviewer-host-ec2-ubuntu-server-the-framebuffer-console-seems-to-be-unavailable

I should :

edit my /etc/default/grub file and add these two lines.GRUB_GFXMODE=1024x768x32
GRUB_GFXPAYLOAD_LINUX=keep

Save the file and run the command

sudo grub2-mkconfig -o /boot/grub2/grub.cfg

unfortunately on the docker image there isn't any grub file :

root@3a9d3758f01f:/etc/default# find / -name grub

/usr/share/desktop-base/futureprototype-theme/grub

/usr/share/desktop-base/lines-theme/grub

/usr/share/desktop-base/softwaves-theme/grub

/usr/share/desktop-base/spacefun-theme/grub

/usr/share/desktop-base/joy-theme/grub

/usr/share/desktop-base/moonlight-theme/grub

so,what to do ?
