On the debian based OS’s (Raspbmc / Raspbian), if you run the device headless most of the time you can ensure the HDMI port is powered off by editing /etc/rc.local and adding the below line above exit 0:
/opt/vc/bin/tvservice -o
(notice its the same line that I posted in the script to turn XBMC off and on in Raspbmc).
Reboot and done. Not sure how much you gain from this but its a nice little trick.
If you want to enable the users on your linux box have their own home page, where you can access from domain.com/~user, its pretty simple!
Under server.modules add: “mod_userdir”
In the main body of the file, add userdir.path = “public_html”.
2. Add the “public_html” folder.
In your account root, (cd ~). run mkdir “public_html”
3. Insert a test index.html file.
cd public_html to get into the directory.
sudo nano index.html to create the index file.
<html><body><h1>Done!</h1></body></html> the html to add to the file. Save and close the file.
4. Restart lighttpd.
sudo /etc/init.d/lighttpd restart
Done! If this didnt work for you leave me a comment and I will see if I can help.
