GSR-KMS-SERVER(1)
π GSR-KMS-SERVER(1) β like, the KMS server for GPU Screen Recorder, bestie β¨
okay so real talk, this is the gsr-kms-server manual page, and it's literally the little companion daemon that makes screen capture work when GPU Screen Recorder needs to talk to your display hardware directly. it's giving "unpaid intern but make it kernel-level" π«Ά and yes, we're gonna go through every single detail because that's what besties do.
πΈ SYNOPSIS πΈ
gsr-kms-server <domain_socket_path> <card_path>
that's it. two little paths and you're off. no cap. β¨
π DESCRIPTION π
gsr-kms-server is a companion daemon for GPU Screen Recorder that gives it Kernel Mode Setting (KMS) access for screen capture, in those environments where you need direct DRM access. basically it's a local server that talks over a Unix domain socket, so GPU Screen Recorder can grab screen content through the KMS interface. main character energy, but in the background π
you typically need this component when GPU Screen Recorder has to get at the display hardware directly, straight past the windowing system, for more efficient or lower-level capture. it lives as a separate process and communicates with the main GPU Screen Recorder instance. it's not the one recording β it's the one making the recording possible. icon behavior, honestly. π
π¦ ARGUMENTS π¦
domain_socket_pathβ the path to the Unix domain socket that the server will create and listen on. this socket is how GPU Screen Recorder and the KMS server chat with each other. put it somewhere where both processes have the right permissions to read and write, okay? don't just yeet it anywhere.card_pathβ the path to the DRM device file (typically/dev/dri/cardX) that the server uses for KMS operations. this is your specific graphics card, bestie. one card, one path. π
β¨ EXAMPLES β¨
start the KMS server using card0 and create the socket at /tmp/gsr-kms.sock:
gsr-kms-server /tmp/gsr-kms.sock /dev/dri/card0
start the KMS server using card1 and create the socket in a user-specific location:
gsr-kms-server ~/.cache/gsr-kms.sock /dev/dri/card1
look at us go. two whole examples. ate and left no crumbs π
π NOTES π
- the
gsr-kms-servertypically runs with elevated permissions to access DRM devices, and that requires root permission. so like... yes, it needs the big permissions. π«Ά - only one instance should run per DRM card at a time. one card, one server, no drama. periodt.
- the server will exit when the client disconnects, or when it gets terminated by a signal. it's not clingy, it knows when to leave π
- the socket file is created by the server and removed when the server exits. it cleans up after itself. we love a tidy queen β¨
π§ FILES π§
/dev/dri/card*β DRM device files for graphics cards/tmp/gsr-kms.sockβ typical location for the domain socket (user-configurable)
