open a terminal window and type "glxinfo". In the first few lines it will tell you if you're running in accelerated mode. Inever got it working in 2.1 but that was my kernel. With YDL 2.2 I got it working with the stock 2.4x kernel but not the benh variant. Has anyone gotten a benh kernel and acceleration to work in YDL 2.2? r.May
