If you do not want to deal with the display manager startup scripts,
|
|
|
|
Here is an example what we did on a vanilla install of Solaris:
|
|
|
|
|
|
|
|
Make the directory /etc/dt/config:
|
|
|
|
|
|
|
|
mkdir -p /etc/dt/config
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Copy over the Xconfig file for customization:
|
|
|
|
|
|
|
|
cp /usr/dt/config/Xconfig /etc/dt/config/Xconfig
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Edit /etc/dt/config/Xconfig and uncomment the line:
|
|
|
|
|
|
|
|
Dtlogin*grabServer: False
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Next, copy over Xsetup for customization:
|
|
|
|
|
|
|
|
cp /usr/dt/config/Xsetup /etc/dt/config/Xsetup
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Edit /etc/dt/config/Xsetup and at the bottom put a line like:
|
|
|
|
|
|
|
|
/usr/local/bin/x11vnc -forever -o /var/tmp/x11vnc.log -bg
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
(tweaked to your local setup and preferences, a password via -rfbauth,
|
|
|
|
|
|
|
|
etc. would be a very good idea).
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Restart the X server and dtlogin:
|
|
|
|
|
|
|
|
/etc/init.d/dtlogin stop
|
|
|
|
|
|
|
|
/etc/init.d/dtlogin start
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
(or reboot or maybe just restart the X session).
