  === These are entirely optional ===
    * ''audioout=list'' / ''audioout="alsa_card.something|output:something"'' - use this to list all available audio outputs / select a particular audio output. Note that when selecting one, the parameter consists of two values (as displayed in the output on /dev/tty8 when specifying ''list'') that need to be separated with a ''|'', and the set of the two values needs to be enclosed in double quotes. Do //not// enclose each value in double quotes separately! Correct example: ''audioout="alsa_card.pci-0000_00_1b.0|output:hdmi-stereo"''
    * ''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 the blue 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.
-   * ''blankdpmsfix'' - This forces the TFT do black for a few seconds during the X startup phase, then forces it back on again.  This fixes an occasional "black screen" issue that occurs with some flaky client/TFT hardware combinations when using DisplayPort connectors, and could otherwise only be remediated by manually turning the TFT off and back on again. (feature available via github repo, soon via x2go repo too)

    * ''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. 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.
    * ''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 FAT/NTFS partition is available. But as stated above, be sure to power-cycle the machine once you're done.
    * ''earlyblankdpmsfix'' - This forces the TFT do black for a few seconds during the initial boot phase (right after the squashfs was downloaded), then forces it back on again.  This fixes an occasional "black screen" issue that occurs with some flaky client/TFT hardware combinations when using DisplayPort connectors, and could otherwise only be remediated by manually turning the TFT off and back on again. Earlyblankdpmsfix can also be called as ''earlyblankdpmsfix=nnnn'', where ''nnnn'' is the blanking time in milliseconds (so, ''earlyblankdpmsfix=1500'' equals 1.5 seconds). (feature available via github repo, soon via x2go repo too)
    * ''homepageurl="URL1[|URL2|URLn]"'' - this is only available in MiniDesktop mode. It allows you to specify one or more web pages that show up on Browser start/when clicking the "Home" icon. URLs need to be separated with a ''|'', and the set of URLs needs to be enclosed in double quotes. Do //not// enclose each URL in double quotes separately! Correct example: ''homepageurl="https://www.google.de|https://wiki.x2go.org"''
