[LightDM] Using LightDM as a headless XDMCP server without physical graphics card
Hi, I'm currently testing the XDMCP functionality of LightDM which seems to work flawless, however, there is one issue which I cannot resolve: The machine I am using for my setup is a dedicated machine running some VM's, these VM's don't have any graphics card associated and run headless and the only form of command is via a web interface or SSH. LightDM seems to use the /dev/fb0 device as graphics card, but that does not exists on a VM. My queston is, how can I use LightDM to run as a headless XDMCP server without the need of a physical present graphics card? The configuration docs did not shed any light on this usage. Thanks in advance! Kind regards, Jeffrey Langerak -------------- next part -------------- An HTML attachment was scrubbed...

Hi Jeffery, Sorry for the late reply Glad to hear XDMCP is working well! I think you just need to add the following to /etc/lightdm/lightdm.conf: [LightDM] start-default-seat=false This will stop the default X server from being started. --Robert On 13 February 2012 20:11, Jeffrey Langerak <j.langerak at me.com> wrote:> Hi, > > I'm currently testing the XDMCP functionality of LightDM which seems to work > flawless, however, there is one issue which I cannot resolve: > > The machine I am using for my setup is a dedicated machine running some > VM's, these VM's don't have any graphics card associated and run headless > and the only form of command is via a web interface or SSH. > > LightDM seems to use the /dev/fb0 device as graphics card, but that does not > exists on a VM. > > My queston is, how can I use LightDM to run as a headless XDMCP server > without the need of a physical present graphics card?

[LightDM] Using LightDM as a headless XDMCP server without physical graphics card
Hi Robert, No problem, better a late answer than no answer at all :). I've set the parameter in the configuration file and at least LightDM seems to start now. Will try to connect to it when I'm home. Thanks!

[LightDM] Using LightDM as a headless XDMCP server without physical graphics card
Hi, I just wanted to let you know that the headless function is now working like a charm! There is one thing though: how can you quit the connection to the XDMCP server and return to lightdm on the local machine, without changing the configfile? Thanks again!
