+If you are running an Arch Linux based distro then you can find gpu screen recorder in the official repositories under the name gpu-screen-recorder (`sudo pacman -S gpu-screen-recorder`).\
 If you are running another distro then you can run `sudo ./install.sh`, but you need to manually install the dependencies, as described below.\
 You can also install gpu screen recorder ([the ui version](https://git.dec05eba.com/gpu-screen-recorder-gtk/)) from [flathub](https://flathub.org/apps/details/com.dec05eba.gpu_screen_recorder), which is the easiest method
 to install GPU Screen Recorder on non-arch based distros.\
 If you install GPU Screen Recorder flatpak, which is the gtk gui version then you can still run GPU Screen Recorder command line by using the flatpak command option, for example `flatpak run --command=gpu-screen-recorder com.dec05eba.gpu_screen_recorder -w screen -f 60 -o video.mp4`. Note that if you want to record your monitor on AMD/Intel then you need to install the flatpak system-wide (like so: `flatpak install --system com.dec05eba.gpu_screen_recorder`).
 
 ## Unofficial install methods

 GPU Screen Recorder uses Ffmpeg so GPU Screen Recorder supports all protocols that Ffmpeg supports.\
 If you want to reduce latency one thing you can do is to use the `-keyint` option, for example `-keyint 0.5`. Lower value means lower latency at the cost of increased bitrate/decreased quality.

+To start/stop (and save) recording use the SIGRTMIN signal, for example `pkill -SIGRTMIN -f "^gpu-screen-recorder"`. The path to the video will be displayed in stdout when saving the video.\
 This way of recording while using replay/streaming is more efficient than running GPU Screen Recorder multiple times since this way it only records the screen and encodes the video once.
 ## Controlling GPU Screen Recorder remotely

-To stop recording send SIGINT to gpu screen recorder. You can do this by running `pkill -SIGINT -f gpu-screen-recorder` or pressing `Ctrl-C` in the terminal that runs gpu screen recorder. When recording a regular non-replay video this will also save the video.\

 ## System notifications get disabled when recording with desktop portal option
 Some desktop environments such as KDE Plasma turn off notifications when you record the screen with the desktop portal option. You can disable this by going into KDE Plasma settings -> search for notifications and then under "Do Not Disturb mode" untick "During screen sharing".
+## The recorded video lags or I get dropped frames in the video
+This is likely not an issue in the recorded video itself, but the video player you use. GPU Screen Recorder doesn't record by dropping frames. Some video players don't play videos with hardware acceleration by default,
+especially if you record with HEVC/AV1 video codec. In such cases it's recommended to play the video with mpv instead with hardware acceleration enabled (for example: `mpv --vo=gpu --hwdec=auto video.mp4`).
+Some corporate distros such as Fedora (or some Fedora based distros) also disable hardware accelerated video codecs on AMD/Intel GPUs, so you might need to install mpv (or another video player) with flathub instead, which bypasses this restriction.
+## My cursor is flickering in the recorded video
+This is likely an AMD gpu driver issue. It only happens to certain generations of AMD GPUs. On Wayland you can record with the desktop portal option (`-w portal`) to workaround this issue.
+This issue hasn't been observed on X11 yet, but if you do observe it you can either record a window (`-w $(xdotool selectwindow)`) or change your xorg config to use software cursor instead (Add `Option "SWcursor" "true"` under modesetting "Device" section in your xorg config file).
+## Password prompt shows up when I try to record my screen
+If GPU Screen Recorder is installed with -Dcapabilities=true (which is the default option) then `gsr-kms-server` is installed with admin capabilities.
+This removes a password prompt when recording a monitor with the `-w monitor` option (for example `-w screen`). However if the root user is disabled on the system then the password prompt will show up anyways.
+If the root user is disabled on your system then you can instead record with `-w focused` or `-w window_id` on X11 or `-w portal` on Wayland.
+## GPU usage is high on my laptop
+GPU usage on battery powered devices is misleading. For example Intel iGPUs has multiple performance levels and the GPU usage reported on the system is the GPU usage at the current performance level.
+The performance level changes depending on the GPU load, so it may say that GPU usage is 80%, but the actual GPU usage may be 5%.
+## The video is too dark when capturing full-range video or 10-bit video
+This is an issue in some broken video players such as vlc. Play the video with a video player such as mpv (or a mpv frontend such as celluloid) or a browser instead.

+.TH GSR\-KMS\-SERVER 1 "2025-12-22" "5.10.2" "GPU Screen Recorder KMS Server Manual"
+.SH NAME
+gsr\-kms\-server \- KMS (Kernel Mode Setting) server for GPU Screen Recorder
+.SH SYNOPSIS
+.B gsr\-kms\-server
+<\fIdomain_socket_path\fR> <\fIcard_path\fR>
+.SH DESCRIPTION
+\fBgsr\-kms\-server\fR is a companion daemon for GPU Screen Recorder that provides
+Kernel Mode Setting (KMS) access for screen capture in environments where
+direct DRM access is required. It acts as a local server that communicates
+via a Unix domain socket, allowing GPU Screen Recorder to capture screen
+content through the KMS interface.
+.PP
+This component is typically used when GPU Screen Recorder needs to access
+display hardware directly, bypassing the windowing system for more efficient
+or lower-level capture. It runs as a separate process and communicates with
+the main GPU Screen Recorder instance.
+.SH ARGUMENTS
+.TP
+.B \fIdomain_socket_path\fR
+Path to the Unix domain socket that the server will create and listen on.
+This socket is used for communication between GPU Screen Recorder and the
+KMS server. The path should be in a location where both processes have
+appropriate permissions to read and write.
+.TP
+.B \fIcard_path\fR
+Path to the DRM device file (typically \fI/dev/dri/cardX\fR) that the server
+will use for KMS operations. This corresponds to a specific graphics card
+in the system.
+.SH EXAMPLES
+Start the KMS server using card0 and create socket at /tmp/gsr-kms.sock:
+.RS
+.B gsr\-kms\-server /tmp/gsr\-kms.sock /dev/dri/card0
+.RE
+.PP
+Start the KMS server using card1 and create socket in a user-specific location:
+.RS
+.B gsr\-kms\-server ~/.cache/gsr\-kms.sock /dev/dri/card1
+.RE
+.SH NOTES
+.IP \(bu 3
+The \fBgsr-kms-server\fR typically runs with elevated permissions to access
+DRM devices, which requires root permission.
+.IP \(bu 3
+Only one instance should run per DRM card at a time.
+.IP \(bu 3
+The server will exit when the client disconnects or when terminated by a signal.
+.IP \(bu 3
+The socket file is created by the server and removed when the server exits.
+.SH FILES
+.TP
+.B /dev/dri/card*
+DRM device files for graphics cards
+.TP
+.B /tmp/gsr-kms.sock
+Typical location for the domain socket (user-configurable)
+.SH SEE ALSO
