Things are not working as I expected... When I have the DFP connected to the Radeon's DVI port, I can not use the frambuffer in Xfree86 4.1 (it complains there is no /dev/fb0), and the log states: Mar 17 13:02:03 Tycho kernel: radeonfb_pci_register BEGIN Mar 17 13:02:03 Tycho kernel: radeonfb: ref_clk=2700, ref_div=12, xclk=27500 from BIOS Mar 17 13:02:03 Tycho kernel: radeonfb: probed DDR SGRAM 65536k videoram Mar 17 13:02:03 Tycho kernel: radeonfb: panel ID string: ?h??^E Mar 17 13:02:03 Tycho kernel: radeonfb: detected DFP panel size from BIOS: 1x0 Mar 17 13:02:03 Tycho kernel: radeonfb: Failed to detect DFP panel size When I have the DFP attached to the Radeon's VGA port, I can run the DFP (albeit in analog more), and the log states: Mar 17 13:13:05 Tycho kernel: radeonfb_pci_register BEGIN Mar 17 13:13:05 Tycho kernel: radeonfb: ref_clk=2700, ref_div=12, xclk=27500 from BIOS Mar 17 13:13:05 Tycho kernel: radeonfb: probed DDR SGRAM 65536k videoram Mar 17 13:13:05 Tycho kernel: radeonfb: ATI Radeon 9000 If DDR SGRAM 64 MB Mar 17 13:13:05 Tycho kernel: radeonfb: DVI port CRT monitor connected Mar 17 13:13:05 Tycho kernel: radeonfb: CRT port no monitor connected Mar 17 13:13:05 Tycho kernel: radeonfb_pci_register END Before I start digging around in the drivers/video/radeonfb.c file, I'm wondering if this problem is known, and if a workaround is available. ..Scott Scott Robert Ladd Coyote Gulch Productions (http://www.coyotegulch.com) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
