如何修复 Linux Mint 上的 xephyr 中运行 remmina 的错误？
终端命令：
Xephyr -ac -screen 1280x720 -br -reset -terminate 2> /dev/null :1 &
DISPLAY=:1 remmina
终端输出：
remmina-Message: 10:06:46.390: Remmina does not log all output statements. Turn on more verbose output by using "G_MESSAGES_DEBUG=all" as an environment variable.
