problem getting stuff to start with a GUI

[zacam87]

ok so im on SL 10.1 and im running in KDE and everyhitng is fine i have no problems except when i open up a console and type in for example

wine hl.exe

it tryes to run it but it says like it cant open the display and it tells me to check to see if x is started (which it is kause im under kde) , tells me to check $DISPLAY <--i dont even know what that is... and tells me to make sure i have the correct display driver. it dossnt do this when i type in firefox, but it does do it when i try to run airsnort. i compiuled airsnort and wine from source but i dont hink that should have anyhting to do with it should it? do you think i need to be logged in as root to run it because when i installed it and compiled it i was root? im a little confused on this one so any help is appreaciated thanks. -ZAc-

It's best not to run things as root unless needed. If you must though, sudo is usually a good way to do so. Or use sux instead of su to get a root shell. Or set $DISPLAY to unix:0.0, like this:
DISPLAY=unix:0.0 wine hl.exe
If that dont work, try localhost:0.0 or 127.0.0.1:0.0 instead, though the first method will be a little faster, even if you don't notice it.
