Ubuntu 23.04 - Won't start

[rogago]

Hello. I installed this utility via Flatpak. It refuses to start due to qt error

alexd@alexd:~$ flatpak run io.github.libvibrant.vibrantLinux
Gtk-Message: 00:35:55.050: Failed to load module "canberra-gtk-module"
Gtk-Message: 00:35:55.051: Failed to load module "canberra-gtk-module"
Qt: Session management error: Could not open network socket
terminate called after throwing an instance of 'std::runtime_error'
what(): this system has no supported display

I have Ubuntu 24.03 and X11

I also tried to build libvibrant, but when I try to change the saturation through it, I get the following error:

libvibrant version 1.0.2
X Error of failed request: BadName (named color or font does not exist)
Major opcode of failed request: 140 (RANDR)
