Cannot login after reboot

mbrando

Hello,

I have an Fresh Ubuntu 20.04 LTS install with Team Viewer 15. 38.3 linked to a paid account.

I'm connecting from Mac with TV 15.35.7

If the user on Ubuntu is logged in with or has lock screen, I can use easy access to remote into machine.

If user is logged out or machine had rebooted sitting at user login screen I cannot login.

Team viewer on remote machine is setup start with system and get notice when machines comes back on line. however, I cannot login with the user already logged in or at lock screen.

Any idea why I cannot connect to the login screen?

Thanks,

Mike

PS

Should I try Fresh install of Ubuntu 22.04 LTS and disable wayland?

Hello,

Just FYI, if anyone else runs into this.

I had to completely disable Wayland to get teamviewer to work at login screen.

And if you are running headless you need a dummy HDMI.

If you have a headless machine (ie: no monitor plugged into it) you'll need to either install a "HDMI headless dummy connector" or you can install a Video Dummy Package:

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

Then add a configuration file for it:

sudo vi /usr/share/X11/xorg.conf.d/xorg.conf

and paste this (adjusting your desired resolution)

Section "Device"
    Identifier  "Configured Video Device"
    Driver      "dummy"
EndSection

Section "Monitor"
    Identifier  "Configured Monitor"
    HorizSync 31.5-48.5
    VertRefresh 50-70
EndSection

Section "Screen"
    Identifier  "Default Screen"
    Monitor     "Configured Monitor"
    Device      "Configured Video Device"
    DefaultDepth 24
    SubSection "Display"
    Depth 24
    Modes "1920x1080"
    EndSubSection
EndSection

Then reboot the machine and voilá
