Teamviewer Host - EC2 Ubuntu Server - The framebuffer console seems to be unavailable

djb · July 2017

I just installed teamviewer host, and all the dependencies on an ubuntu 14 server. When I run teamviewer setup I get this

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.

I am accessing this server through ssh on my terminal on my mac. Any tips?

Dear djb,

Thank you for your post.

TeamViewer headless setup requires framebuffer support at 32bit.

If framebuffer is not enabled TeamViewer headless setup will not work.

That's the reason why you're getting the framebuffer error.

To fix your issue, please edit your /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

Then reboot the computer.

If you have any other questions please don’t hesitate to contact us.

Best,

Christian

I did all of that, having to modify the command for grub 1, and I get

Dear djb,

Thank you for your post.

If you have grub 1 please follow these instructions.

In your favorite editor, please edit the file /boot/grub/menu.lst

Append the desired frame buffer mode to your system. In this case, vga=833 that is the recommended mode.

An example entry:

###Don't change this comment - YaST2 identifier: Original name: linux###
title SUSE Linux Enterprise Server 11 SP4 - 3.0.101-63
root (hd0,1)
kernel /boot/vmlinuz-3.0.101-63-default root=/dev/sda2 vga=833 resume=/dev/sda1 splash=silent showopts
initrd /boot/initrd-3.0.101-63-default

Then reboot.

Hope this solution works for you.

Best regards,

Christian

This is what I did.

I used

$ wget https://download.teamviewer.com/download/linux/teamviewer-host_amd64.deb

I installed it with

$ sudo dpkg -i /path/to/deb/file

followed by

$ sudo apt-get install -f

## ## End Default Options ##

title           Ubuntu 16.04.3 LTS, kernel 4.4.0-89-generic
root            (hd0)
kernel          /boot/vmlinuz-4.4.0-89-generic root=LABEL=cloudimg-rootfs vga=833 ro console=hvc0
initrd          /boot/initrd.img-4.4.0-89-generic

title           Ubuntu 16.04.3 LTS, kernel 4.4.0-89-generic (recovery mode)
root            (hd0)
kernel          /boot/vmlinuz-4.4.0-89-generic root=LABEL=cloudimg-rootfs vga=833 ro  single
initrd          /boot/initrd.img-4.4.0-89-generic

Is that at all correct?
When I restarted the server and ran sudo teamviewer setup I got

An X server is currently running on the active VT (virtual console). Please shut down your X session or  display manager.

So I ran

$ sudo service lightdm stop

Then I tried sudo teamviewer setup again then I got

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.

On a last note, are you sure this will work for an aws ec2 ubuntu 16 server?

I typed

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

djb · February 2018

After doing as you said for updating the grub file, I type

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

Then I reboot

Then I type

sudo teamviewer setup

And it actually lets me login to my account now. I even get an email authorizing the trusting of a new device. But it hangs at the setting your device point.

It might be my inbound ports, which I only have 80 and 22 open, or it's another error.

Any help would be appreciated.

I have followed the exact same error and all the suggestions and I still get the

I have the I386 deb and a 32bit HP Server, I have had to change up the commands as I will edit bellow to allow the server OS to recognise the intended commands since the ones listed in the thread are obviously not for a GRUB system on the Ubuntu 16 Server 32 bit system as they give the error command not found when you copy and paste them under SSH or CLI directly but allude to how to list the correct commands which the ones posted are not in that list but s simular one is i change the syntax to that..

IS it possible for Tech support to provide clear step by step instructions besides the cookie cutter of

As this edited version works for me to change up grub I still receive the error after a sudo reboot command

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.

So how do I get /dev/fbo working?

I copy and pasted the suggested updates exactly as posted.
