Re: Looking for Suggestions for a Headless Music-Client Setup (SOLVED)
I found a simple solution for my application:
1. I use kdm with autologin. That starts KDE with a user set up to autorun
amarok and x11vnc -many, without any intervention on boot. It does this with
a script in ~/.kde/Autorun. I'm not worried about security in my LAN which
is behind a firewall and not open to outside access.
2. I use the following in xorg.conf to allow X to start without a keyboard or
mouse attached.
Section "ServerFlags"
Option "AllowMouseOpenFail"
Option "AllowKeyboardOpenFail"
EndSection
The box boots and I can access the desktop with a VNC client from anywhere in
the LAN and play music from amarok onto my stereo.
I still need to find a decent USB-WLAN NIC for the box. It's a mini-pc and
doesn't have a pci slot. Any suggestions there? A USB-Stick using the
zd1211rw module didn't work reliably.
