My Tumbleweed is running in VMware Fusion on my MacBook, everything was working fine until I upgrade to tumbleweed snapshot-20180815. The error " Failed to start setup virtual console" appears during the boot process. Then I can not open the window of "system setting" "system log", "hardware information" and others through "Yast", nothing happens when I click on them. However, I can print out "/var/log/messages" via terminal. Furthermore, the folder window was flickering for few seconds the first time open it, and the window seems to be slow down even if I just open a 1KB text file.

below is the information when I type “systemctl status systemd-vconsole-setup "but I don’t have enough knowledge about linux to trace this bug, anyone know I to fix this issue?
