------- Additional Comments From thunderbird2k@gmx.net 2007-02-04 05:29 ------- WoW doesn't seem to like the available pixelformats. It seems you are running X at 16bit and it is looking for a format with a depth buffer of 24. On Windows there's depth switching but that doesn't exist on Linux so the available formats are limited.
Try setting your X to 24bit I expect WoW to work then.
