Window manager crashes after connecting to VPN

Hi. After the last update everything is working fine until I connect to VPN (openvpn). Once I connect I can't open any GUI apps I got one of the following errors

- Unable to open X display.
- Could not connect: Connection refused. Error: cannot open display: :0
- Can't connect to X11 window server using ':0' as the value of the DISPLAY variable.

Everything gets back to normal when I turn VPN connection off.

Re: Window manager crashes after connecting to VPN

hostnamectl

Before connecting to VPN

me@archlinux ~ $ hostnamectl
   Static hostname: n/a                             
Transient hostname: archlinux
         Icon name: computer-desktop
           Chassis: desktop
        Machine ID: ....
           Boot ID: ...
  Operating System: Arch Linux                      
            Kernel: Linux 5.14.8-arch1-1
      Architecture: x86-64
   Hardware Vendor: To Be Filled By O.E.M.
    Hardware Model: To Be Filled By O.E.M.

After connecting to VPN

me@archlinux ~ $ hostnamectl
   Static hostname: n/a                                        
Transient hostname: 172-127-1-6.abc.bac.etc.etc
         Icon name: computer-desktop
           Chassis: desktop
        Machine ID: ...
           Boot ID: ...
  Operating System: Arch Linux                                 
            Kernel: Linux 5.14.8-arch1-1
      Architecture: x86-64
   Hardware Vendor: To Be Filled By O.E.M.
    Hardware Model: To Be Filled By O.E.M.

After changing manually back to archlinux it starts working fine

sudo hostnamectl --transient set-hostname archlinux

Do I need to adjust some VPN settings not to have hostname changed?

Re: Window manager crashes after connecting to VPN

Set a static hostname, you don't want NM to juggle that around willy-nilly under no circumstances (because it amongst others breaks the X11 connection)
