X server is running only in 640x480 if my radeon is connected with DVI flat panel. I'm not able to switch other modes. This strange behaviour happens only with a DVI connected flat panel. The flat panel is a Hyundai ImageQuest L70A and my working xfree86 release is 4.2.99.1 (from xfree86 cvs). What's going wrong ? Any ideas ? Thanks in advance Tim
