/root/.vnc/config文件的使用。

 

从rhel7.4开始，vnc server options 存储在/root/.vnc/config文件中，该文件的内容如下：
[root@hgsec434 .vnc]# cat config
## Supported server options to pass to vncserver upon invocation can be listed
## in this file. See the following manpages for more: vncserver(1) Xvnc(1).
## Several common ones are shown below. Uncomment and modify to your liking.
##
# securitytypes=vncauth,tlsvnc
# desktop=sandbox
# geometry=2000x1200
# localhost
# alwaysshared
[root@hgsec434 .vnc]#

比如 resolution, color depth, 
之前在ExecStart表示如下： ExecStart=/sbin/runuser -l testuser1 -c "/usr/bin/vncserver %i -geometry 1024x768 -depth 24"

具体有哪些options，请见 man 1 vncserver
