Before Login, there is Xorg process at my Ubuntu 18.04 as below.
root@chenyu-ubuntu1804:~# ps -ef|grep Xorg
gdm 927 925 0 06:19 tty1 00:00:07 /usr/lib/xorg/Xorg vt1 -displayfd 3 -auth /run/user/119/gdm/Xauthority -background none -noreset -keeptty -verbose 3
After Login, check again with two Xorg instances as below. One is gdm, the other is the login user.
root@chenyu-ubuntu1804:~# ps -ef|grep Xorg
gdm 927 925 0 06:19 tty1 00:00:07 /usr/lib/xorg/Xorg vt1 -displayfd 3 -auth /run/user/119/gdm/Xauthority -background none -noreset -keeptty -verbose 3
chenyu 11665 11632 0 10:54 tty2 00:00:00 /usr/lib/xorg/Xorg vt2 -displayfd 3 -auth /run/user/1000/gdm/Xauthority -background none -noreset -keeptty -verbose 3
I would like to know whether there is configuration of GDM/Xorg to not start the second Xorg process, then share to use the first instance, just like Ubuntu16.04. As my session connected to the first instance, after login, it still connect the first one, then no resopnse for my keyboard, mouse, etc response.
Any help is appericiated. thanks.
