I got two accounts in my kali linux, installed in a usb.one is root while the other one is non-root. When i installed applications (e.g. chromium, vlc, wine), it worked without any problems(instance launch) in the non-root account but in the root account, which i always use, have the icon appear in the application menu but when i click the app(s), no respond. For wine, it worked from the terminal command but also not launching ui. Many thx!!
