I installed the Wine SFS and don't want to run Wine applications as root. Is there any way to run Wine applications as user spot? I tried to run winecfg after su - spot but it said it can't find the DISPLAY 
@hungnguyengia Remember that wine applications that run as spot won't be able to access root's folders, and their WINEPREFIX (the emulated Windows file system) lives in /home/spot. Having said that, I too run wine applications as spot - with the limitation I mentioned. When I want access to any folder I run wine as root - with the inconvenience that a new WINEPREFIX folder gets created in /root.
