[dev] AdvanceMAME in dwm

[alphachi]

I can use AdvanceMAME in dwm before a few days.
When I update to the latest nvidia-driver,  the blackscreen occured after
running AdvanceMAME.
I think it's the problem of nvidia-driver, but when I use the other window
manager, for example, enlightenment, AdvanceMAME is OK.
Is it the problem of dwm? Thanks!
