You can fix the timing for a DTU regardless of the token (that's the '-c <dtu> -t default' combination). You can not fix the timing for a token regardless of the DTU (that would be '-c default -t <token>', but the command won't accept that.) The first is allowed because it's not unusual to have a DTU that is attached to a monitor or to other video equipment that does not respond to DDC but must nevertheless be driven with a specific timing. The second is disallowed because it creates a huge risk that the token will become unusable when hotdesked to some DTUs. The monitors attached to those DTUs may be unable to accept the timing that has been tied to the token. When this happens it's very hard to figure out what's giong on and there's nothing the user can do to recover from it, other than getting an admin to intervene. (If this mode was allowed then it would also create an interesting conflict: if both the DTU and the token have a forced timing, which timing wins? But that's resolvable, it's not the reason why '-c default -t <token>' is disallowed.) The safer way to do all of this, provided that your monitors respond to DDC requests, is to not use 'utresadm' at all. Instead use 'utxconfig' to force the dimensions of the X desktop. This allows the DTU to choose a monitor timing that matches the desktop, and since the DTU will never drive a timing that the monitor can not accept there's no risk that any token will be shut out by forcing a timing that its monitor can not accept. 'utxconfig' lets the admin set a system-wide default for the desktop dimensions of all tokens or for individual tokens, and it also lets the user set the dimensions for an individual token. (That's assuming that the user has access to the 'utxconfig' command. If you're using kiosk mode then the users might not have access to any local commands.)
