Try building radeonfb in the kernel and booting with radeonfb.default_dynclk=-1, let me know if that works. fbdev's in modules have always been sort-of dodgy.... The "dynclk" thing has issues, the upstream code from ATI has some bugs plus there is something weird going on which I suspect might be a miscompile of a bit of code in there. I'll send a patch working around that today. Ben.
Ok, did that. Same result. The only thing displayed is the system caret. I can see it moving left and right while the system boots and "displays" the messages (X is working nicely). I did compile debug support, so I'm including the output. Tell me if I can test something else, Thanks very much, Marc debug output: radeonfb (0000:01:00.0): Found 32768k of DDR 64 bits wide videoram radeonfb (0000:01:00.0): mapped 16384k videoram radeonfb: Retreived PLL infos from BIOS radeonfb: Reference=27.00 MHz (RefDiv=12) Memory=230.00 Mhz, System=166.00 MHz radeonfb: PLL min 12000 max 35000 1 chips in connector info - chip 1 has 1 connectors * connector 0 of type 2 (CRT) : 2300 Starting monitor auto detection... radeonfb: I2C (port 1) ... not found radeonfb: I2C (port 2) ... not found radeonfb: I2C (port 3) ... not found radeonfb: I2C (port 4) ... not found radeonfb: I2C (port 2) ... not found radeonfb: I2C (port 4) ... not found Non-DDC laptop panel detected radeonfb: I2C (port 3) ... not found radeonfb: I2C (port 4) ... not found radeonfb: Monitor 1 type LCD found radeonfb: Monitor 2 type no found radeonfb: panel ID string: QDI QD141F1LH01 radeonfb: detected LVDS panel size from BIOS: 1400x1050 BIOS provided panel power delay: 1500 radeondb: BIOS provided dividers will be used ref_divider = 6 post_divider = 4 fbk_divider = 48 Scanning BIOS table ... 320 x 350 320 x 400 320 x 400 320 x 480 400 x 600 512 x 384 640 x 350 640 x 400 640 x 475 640 x 480 720 x 480 720 x 576 800 x 600 848 x 480 1024 x 768 1152 x 864 1280 x 1024 1400 x 1050 Found panel in BIOS table: hblank: 288 hOver_plus: 40 hSync_width: 112 vblank: 13 vOver_plus: 0 vSync_width: 3 clock: 10800 Setting up default mode based on panel info radeonfb (0000:01:00.0): ATI Radeon LW radeonfb_pci_register END ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
