# dde-seatd-launch(1)

Start a process with its own dde-seatd instance

## NAME

dde-seatd-launch - Start a process with its own dde-seatd instance

## SYNOPSIS

**dde-seatd-launch** \[options\] \[--\] command

## OPTIONS

- **-l \<loglevel\>**

  Log-level to pass to dde-seatd. See [**dde-seatd**(1)](/dde-seatd/1.md) for information about available log-levels.

- **-h**

  Show help message and quit.

- **-v**

  Show the version number and quit.

## DESCRIPTION

dde-seatd-launch starts a dde-seatd instance with a dedicated socket path, waits for it to be ready, and starts the specified command with SEATD\_SOCK set appropriately. Once the specified command terminates, the dde-seatd instance is also terminated.

dde-seatd requires root privileges to perform its tasks. This can be achieved through SUID of dde-seatd-launch or by running dde-seatd-launch as root. dde-seatd-launch will drop privileges from the effective user to the real user before running the specified command. If the real user is root, this is simply a noop. You should only run dde-seatd-launch as root if you intend for the specified command to run as root as well.

dde-seatd-launch serves a similar purpose to the libseat "builtin" backend, but is superior to it for two reasons:

- 1\.

  The specified command never runs as root

- 2\.

  The standard dde-seatd executable and DDE libseat-compatible backend is used

## EXIT STATUS

dde-seatd-launch exits with the status of its child. When the child terminates on a signal *N*, dde-seatd-launch exits with the status 128 + *N*.

If dde-seatd-launch fails because of another error, it exits with a non-zero status.
