I am pretty new to linux so please excuse any foolish mistakes.

I am trying to manually install gpu-screen-recorder(GSR) to get rid of an annoying password prompt that I can’t seem to disable in the flatpak version. I know there must be some way to do it because this prompt didn’t show up on Pop!_OS, but maybe it’s just not possible on Nobara KDE/Fedora. I noticed in the install.sh of GSR, that setcap cap_sys_admin+ep is called on the executable. So if you know any way of replicating something like that for flatpaks that is simpler than installing GSR manually, feel free to let me know.

I tried checking the dependencies listed, but was unable to figure out how to really make sure they are installed and accessible for GSR.

For example: I tried checking for libglvnd by running dnf list libglvnd. Sure enough, it returns

Installed Packages
libglvnd.i686                                         1:1.6.0-2.fc38                                       @anaconda
libglvnd.x86_64                                       1:1.6.0-2.fc38                                       @anaconda

But then I tried checking for mesa, so I ran dnf list mesa. But it returned

Available Packages
mesa.src                                    23.2.1-1.fc38                                     nobara-baseos         
mesa.src                                    23.2.1-1.fc38                                     nobara-baseos-multilib

It says ‘available packages’, so not installed, right?

Well, glxinfo -B says I am using mesa 23.2.1, so it seems to be installed, I guess?

So, just assuming I had everything necessary, I cloned the repo and tried to just run install.sh. However, of course I get an error message: wayland-scanner: command not found.

I am a bit confused because I am running on wayland, and checked using loginctl show-session 1 -p Type.

How do I properly make sure the dependencies are available?

    You can just run the same command on the executable installed by flatpak. On my system it can be found in /var/lib/flatpak/app/{app name}/current/active/files/bin.

      I didn’t consider that an option because whenever I searched for setcap and flatpak, most threads were pretty dismissive and told OP that flatpak is made with security in mind so doing that isn’t supported.

      Regardless, I tried it just now, but the password prompt (image below) still shows up when launching the autostart .desktop file I created. The .desktop file launches a script I wrote, which in turn actually starts GSR through flatpak, in case that changes anything.

      password prompt

      Do I assume correctly that this prompt might be gone if I set the capabilities of /usr/bin/flatpak? It’s not something I want to do, so I’ll probably keep trying to get the manually built version installed.
