    * ''xinerama=left-of|right-of|above|below|same-as'' - Allows you to specify how multiple screens are handled (same-as clones the primary screen to all secondary screens, the other commands will cascade and thus expand the screen). Note that the current implementation will enforce "same-as" if it detects a touch screen driver (wacom) and no other pointing device. This is so you won't get stuck being unable to log off, for example, due to your touch device being limited to one screen.
    * ''xorg-driver=DRIVERNAME'' - will skip graphics driver autodetection and force the specified driver instead. This is a standard parameter of live-boot, and not specific to X2Go.
    * ''xorg-resolution=HRESxVRES'' - will force the horizontal resolution to HRES and the vertical resolution to VRES, e.g. ''xorg-resolution=1280x1024'', useful if autodetection for the correct screen size fails, but you do get as far as seeing the X2Go GUI. This is a standard parameter of live-boot, and not specific to X2Go.
    * ''xorgconfurl=tftp|http|https|ftp://your-http-server-ip-or-dns-here/x2go-tce/x2go-tce.xorg.conf'' - when a client outright refuses to boot into the graphical X2Go login screen, but gets stuck at the console or a black screen instead, yet you can get the GUI to work using a regular Linux on the same hardware, you can disable the X Server's autodetection and force it to use the xorg.conf specified here.  Note that you should use a more descriptive name for the file, as described below. **Attention: Whoever manages to spoof the server name can inject rogue xorg config files into your ThinClients.**  To mitigate this risk, use HTTPS, where the attacker would have to spoof both server name and matching certificate.
-   * ''xroot=[0xaabbcc|URI1[|URI2|...]]'' - can be used to set a local desktop background image or color (in hex format, with leading 0x, not leading #). On the main screen, this is only visible during startup, while additional screens will display whatever is set for them when there is no active session. The background also becomes visible for a short moment when the optional local screensaver activates or deactivates. Specifying more than one image will cause the first image to show up on the first screen, the second image on the second screen, and so on (feature available via github repo, soon via x2go repo too).

    * ''xrootmode=center|fill|scale|tile'' can be used to determine how the local desktop background image(s) should be positioned. If the parameter has been set, but something is wrong, it will default to a //grey mesh// background. (feature available via github repo, soon via x2go repo too). (feature available via github repo, soon via x2go repo too)
    * ''xsaveridletime=n'' - this value determines how long the screen should have been idle before the local slideshow screensaver sets in (value given in seconds). We recommend using 60 seconds less than for the server-sided, locking screensaver. (feature available via github repo, soon via x2go repo too)
    * ''xsaverimages=[URI1[|URI2|...]]'' - if you want a local, non-locking slideshow screensaver, you can specify image URLs here. These Images will be downloaded once, at boot. That way, one can display a slideshow without having to push the images across the network every time. Especially for slow links, this is the recommended way of running a slideshow screensaver. For security, combine this with a locking screensaver on the server with only one slide or a black background. (feature available via github repo, soon via x2go repo too)
    * ''xsaverimgtime=n'' - this determines how long each slide of the local, non-locking screensaver will be shown. (feature available via github repo, soon via x2go repo too)
