Recently I updated from Ubuntu 12.04 to 14.04 and i had a Mad Catz Rat 7 working fine. I followed a tutorial on editing the xorg.conf file and mapping the buttons

Section "InputClass"
Identifier "Mouse Remap"
MatchProduct "Saitek Cyborg R.A.T.7 Mouse"
MatchDevicePath "/dev/input/event*"
Option "ButtonMapping" "1 2 3 4 5 6 7 2 9 10 11 12 0 0 0"
EndSection

In 14.04, I can't seem to get it working. I followed the same steps but this time i get a warning

jayden@jayden-System-Product-Name:~$ sudo gedit /etc/X11/xorg.conf
[sudo] password for jayden: 

(gedit:4347): Gtk-WARNING **: Calling Inhibit failed:  
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name  
org.gnome.SessionManager was not provided by any .service files

(gedit:4347): Gtk-WARNING **: Calling Inhibit failed:   
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name  
org.gnome.SessionManager was not provided by any .service files

I have no idea what this means but nothing is working and i can't seem to find any hints as to why...

  • These warnings are related to gedit and not xorg.conf

  • After a bit of tampering with things i managed to get it working (not sure what i did) However when i start my computer and log in, i have to log out and in again for it to take affect. This is not a big deal but if anyone knows why?

Yes, these error occurs because there is no xorg.conf in the directory /etc/X11/. You have to create a file or download it from somewhere else.Then you have to edit the file like you tried before.

To make your changes work, you have to restart your xserver by using this command sudo restart lightdm
