Lauching program with Nvidia GPU fails

Hi Everyone,

When i try to run anything with command DRI_PRIME or prime-run a have this error:

Error spawning command line “dbus-launch --autolaunch=56dff34a42dd4ee9b01a0c309e943846 --binary-syntax --close-stderr”: Child process exited with code 1
gui_dbus_name_lost: connection to the bus cannot be established.

I use GNOME version. I have HP laptop with amd CPU and Nvidia GPU.
