I want to add access to my Ubuntu 11.10 machine over vnc. I tried two things that are not exactly working as I want. First I simply tried to run Xvnc with the following command: > sudo /usr/bin/Xvnc :1 -query localhost -geometry 1680x1050 -depth 16 -once -fp /usr/share/fonts/X11/misc -DisconnectClients=0 -NeverShared passwordFile=/root/.vncpasswd This option works but when I connect to my vnc server it stays in the default X view and never goes to the login screen. I had a similar problem with previous versions of Ubuntu but I could activate "remote login" in gdm but I cannot find an equivalent option in lightdm in Ubuntu 11.10. Is there any equivalent option? Next, after googling for a while I saw that lightdm is natively supporting Xvnx so I added these lines in lightdm.conf as mentioned in the documentation: [VNCServer] enabled=true port=5902 width=1680 height=1050 depth=8 In this case I can connect to the server with vncclient but I always get "No password configured for VNC Auth". I tried to run "sudo vncpasswd" to set a root password for xvnc but it does not work. I also specified "sudo vncpasswd /root/.vncpasswd" and "sudo vncpasswd /root/.vnc/passwd" because I tought these were the default pw files for root but it did not work. In /var/log/lightdm/lightdm.log I can see that ligthdm calls "/usr/bin/Xvnc :1 -auth /var/run/lightdm/root/:1 -inetd -nolisten tcp -geometry 1680x1050 -depth 8" but no passwd file is specified. So how could I specify a password for this VNC access? I hope I included enough details. Thanks for you help... -- Jean-Michel
