  These are //not yet implemented//, but planned for a future release:
    * ''blank=n|n:n:n'' - Will disable (''blank=0'') or set screensaver timeout. Use ''blank=n:n:n'' to set DPMS Standby/Suspend/Off values. Standby value equals screensaver timeout value. All values are given in seconds.
    * ''nodpms'' - Will not touch DPMS settings at all (by default, ''blank=0'' does both ''xset s off'' and ''xset -dpms''). Use this along with ''blank=n'' if you do want to blank the screen, but your screen is confused by
DPMS settings.
-   * ''tcpprint'' - Will allow you to use local LPT/USB printers like "dumb" network printers (listening to port 9100 and above). Requires MAC->IP mapping in DHCP server (and optionally, DNS->IP mapping), or static IPs - else your print jobs will end up on random devices. This setup is preferred over the X2GoClient's built-in printing for locally attached printers if X2GoServer and ThinClients are on the same network. It is not recommended when your X2Go connection goes across the internet or when the ThinClient is actually a laptop roaming between different networks.

Requires MAC->IP mapping in DHCP server (and optionally, DNS->IP mapping), or static IPs - else your print jobs will end up on random devices. This setup is preferred over the X2GoClient's built-in printing for locally attached printers if X2GoServer and ThinClients are on
the same network. It is not recommended when your X2Go connection goes across the internet or when the ThinClient is actually a laptop roaming between different networks. **Attention:** When used without ''tcpprintonlyfrom'' (see below), this means anyone that can reach your thin client via e.g. ping can also send print jobs to it!  
    * ''tcpprintonlyfrom=x.x.x.x'' - Will allow you to specify which IP address may connect to Port 9100 and above for printing to a locally attached LPT/USB printer. This should be the IP of your CUPS server or whatever print server system you use.  Understands the same syntax as xinetd's ''only_from''. 
  
  These are //not yet implemented//, but planned for a future release, and only intended to be used with TCE images stored on local media:
    * ''updateurl=rsync|https|http|ftp://your-http-server-ip-or-dns-here/path-to-update-files'' - Will allow you to update an image in the background when using local storage instead of PXE. Download task will
start at a randomized interval to avoid unintentional dDOSing of the update server/network infrastructure. The updater will even work when using NTFS for local storage, but only if the //toram// boot option is used. Regardless of NTFS or not, the updater requires three directories: ''/boot/live1, /boot/live2, /boot/live-download'' **Attention:** Whoever manages to spoof the server name can deploy rogue images to your ThinClients.  Even though it is slower, using an HTTPS web server is the safer way of doing this. Be sure that your web server delivers a last-modified header for all files.
