So, i've changed the .conf file adding my NVIDIA driver (nvidia-440) and when i try to optirun it just doesn't work, so i need some help with that, i've an Intel I7-7500U (HD 620) and a Geforce 920mx, i need help finding log files to solve this problem, thank.
optirun glxgears -info
[ 1036.915525] [ERROR]The Bumblebee daemon has not been started yet or the socket path /var/run/bumblebee.socket was incorrect.
[ 1036.915603] [ERROR]Could not connect to bumblebee daemon - is it running?
When i try to see bumblebee.socket for any config or help:
sudo gedit /var/run/bumblebee.socket
No text or archives in this file, and it isn't at the path as well. There was some error installing Bumble bee, an Error 404 in the repository. Thanks for the help.
bumblebee.conf file:
# Configuration file for Bumblebee. Values should **not** be put between quotes
Server options. Any change made in this section will need a server restart
to take effect.
[bumblebeed]
The secondary Xorg server DISPLAY number
VirtualDisplay=:8
Should the unused Xorg server be kept running? Set this to true if waiting
for X to be ready is too long and don't need power management at all.
KeepUnusedXServer=false
The name of the Bumbleblee server group name (GID name)
ServerGroup=bumblebee
Card power state at exit. Set to false if the card shoud be ON when Bumblebee
server exits.
TurnCardOffAtExit=false
The default behavior of '-f' option on optirun. If set to "true", '-f' will
be ignored.
NoEcoModeOverride=false
The Driver used by Bumblebee server. If this value is not set (or empty),
auto-detection is performed. The available drivers are nvidia and nouveau
(See also the driver-specific sections below)
Driver=nvidia
Directory with a dummy config file to pass as a -configdir to secondary X
XorgConfDir=/etc/bumblebee/xorg.conf.d
Xorg binary to run
XorgBinary=/usr/lib/xorg/Xorg
Client options. Will take effect on the next optirun executed.
[optirun]
Acceleration/ rendering bridge, possible values are auto, virtualgl and
primus.
Bridge=auto
The method used for VirtualGL to transport frames between X servers.
Possible values are proxy, jpeg, rgb, xv and yuv.
VGLTransport=proxy
List of paths which are searched for the primus libGL.so.1 when using
the primus bridge
PrimusLibraryPath=/usr/lib/x86_64-linux-gnu/primus:/usr/lib/i386-linux-gnu/primus
Should the program run under optirun even if Bumblebee server or nvidia card
is not available?
AllowFallbackToIGC=false
Driver-specific settings are grouped under [driver-NAME]. The sections are
parsed if the Driver setting in [bumblebeed] is set to NAME (or if auto-
detection resolves to NAME).
PMMethod: method to use for saving power by disabling the nvidia card, valid
values are: auto - automatically detect which PM method to use
bbswitch - new in BB 3, recommended if available
switcheroo - vga_switcheroo method, use at your own risk
none - disable PM completely
https://github.com/Bumblebee-Project/Bumblebee/wiki/Comparison-of-PM-methods
Section with nvidia driver specific options, only parsed if Driver=nvidia
[driver-nvidia]
Module name to load, defaults to Driver if empty or unset
KernelDriver=nvidia-440
PMMethod=auto
colon-separated path to the nvidia libraries
LibraryPath=/usr/lib/nvidia-440:/usr/lib32/nvidia-440:/usr/lib/x86_64-linux-gnu:/usr/lib/i386-linux-gnu
comma-separated path of the directory containing nvidia_drv.so and the
default Xorg modules path
XorgModulePath=/usr/lib/nvidia-440/xorg,/usr/lib/xorg/modules
XorgConfFile=/etc/bumblebee/xorg.conf.nvidia
If set to true, will always unload the kernel module(s) even with
PMMethod=none - useful for newer Optimus models on which the kernel power
management works out of the box to power the card on/off without bbswitch.
AlwaysUnloadKernelDriver=false
Section with nouveau driver specific options, only parsed if Driver=nouveau
[driver-nouveau]
KernelDriver=nouveau
PMMethod=auto
XorgConfFile=/etc/bumblebee/xorg.conf.nouveau
Found another log, clarifying what happened.

Switched nvidia-440 for nvidia, restarted the service and now it is getting me another error:

Fixed it with help of this post: bumblebee doesn't work on Ubuntu 18.04
