[gpu-screen-recorder](https://git.dec05eba.com/gpu-screen-recorder/) needs to be installed to use gpu screen recorder gtk. +Recording monitors requires a gpu with NvFBC support. Normally only tesla and quadro gpus support this, but by using https://github.com/keylase/nvidia-patch you can do this on all gpus that support nvenc as well (gpus as old as the nvidia 600 series), provided you are not using outdated gpu drivers. ## Screenshots  diff --git a/project.conf b/project.conf index 08d53bb..8720ecb 100644 --- a/project.conf +++ b/project.conf @@ -7,4 +7,5 @@ platforms = ["posix"] [dependencies] gtk+-3.0 = "3" x11 = "1" -libpulse = ">=13" +xrandr = "1" +libpulse = ">=13"
