关于需要root权限启动图形应用记录

环境

• Kernel: 6.8.4-arch1-1
• OS: Arch Linux x86_64
• DE: hyprland

问题来源

在vmware中安装win11，想更改Edit>Preferences>Memory到"Fit all virtual machine memory into reserved host RAM"来提高访问内存效率，但必须用root运行vmware才能改变.

直接使用sudo vmware会出现

➜  ~ sudo vmware
Authorization required, but no authorization protocol specified


(vmware:28905): Gtk-WARNING **: 14:53:33.168: cannot open display: :0.0

解决方案

尝试使用DISPLAY=:1运行sudo vmware，问题还是存在

➜  ~ DISPLAY=:1 sudo vmware
Authorization required, but no authorization protocol specified


(vmware:29900): Gtk-WARNING **: 15:03:21.949: cannot open display: :1

使用xhost临时允许用启本地用户的X seesion 。参考：arch wiki xhost

➜  ~ sudo pacman -S xorg-xhost
➜  ~ xhost si:localuser:root
Authorization required, but no authorization protocol specified

xhost:  unable to open display ":0.0"

仍然显示unable to open display ":0.0"，尝试使用DISPLAY=:1运行

➜  ~ DISPLAY=:1 xhost si:localuser:root
localuser:root being added to access control list

然后再次使用sudo运行vmware

➜  ~ DISPLAY=:1 sudo vmware

运行成功

别忘了关闭对root的授权

➜  ~ DISPLAY=:1 xhost -si:localuser:root
localuser:root being removed from access control list
