    * ''bg=https|http|ftp://your-http-server-ip-or-dns-here/x2go-tce/x2go-tce-bg.svg'' - use this to specify an SVG file to "brand" your X2Go-TCE with. It will replace theblue background theme of the login screen. See below for how to add this file to your HTTP, HTTPS, or FTP server.  **Attention: Whoever manages to spoof the server name can inject rogue images into your ThinClients.** To mitigate
this risk, use HTTPS, where the attacker would have to spoof both server name and matching certificate.
    * ''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.
    * ''branding=https|http|ftp://your-http-server-ip-or-dns-here/x2go-tce/x2go-tce-branding.svg'' - use this to specify an SVG file to "brand" your X2Go-TCE with. It will replace the seal icon in the lower left of the login screen.

-   * ''copysecring'' - this will scan for USB media and fixed disk media (with USB media taking precedence) at boot for one or more of the
following directories: ''config/ssh'', 'ssh', ''.ssh''. The volume must be labeled ''X2GO-TCE-LIVE'' or ''PORTABLEAPP'' and may use any supported file system. Any SSH Secret Keys found there will be copied into /home/user/.ssh (in the ramdisk), with proper permissions and ownerships for the default user account. This may come in handy when you are using SSH Secret Keys on USB media, but need to log in and out of sessions often, and don't want to leave the USB media plugged in all the time/don't want to have to re-insert it before each session startup. **Attention: This poses a security risk when other people are using your ThinClient afterwards (as they will have access to your keys).**  To mitigate this risk,be sure to power-cycle the ThinClient once you are done. You //should// specify this parameter when booting X2Go-TCE-Live from portable media when you want to use SSH Secret Keys, to make sure your secret key on the VAT/NTFS partition is available.

    * ''ldap=ldap.example.com:389:cn=cngoeshere,dc=example,dc=com'' - this allows you to specify an LDAP server to connect to - note that this is not needed for LDAP-based authentication, only when you intend to store entire session profiles in LDAP. You should really consider using the X2Go Session Broker instead.
    * ''ldap1=ldap-backupserver-1.example.com:389'' - this allows you to specify the first of up to two LDAP backup servers when using LDAP authentication
    * ''ldap2=ldap-backupserver-2.example.com:389'' - this allows you to specify the second of up to two LDAP backup servers when using LDAP authentication 
    * ''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.
