I have a Radeon 9000 Pro with two 1280x1024 LCDs connected, one to the DVI connector and one to the CRT connector. When it boots, I get a glimpse of the penguin logo for a moment, and then the screen goes blank and stays blank. If I start the Radeon XFree86 server then both screens come back to life and work fine. I get the following in my boot log: Linux version 2.6.2-rc2 (root@gold) (gcc version 2.95.4 20011002 (Debian prerelease)) #1 Mon Jan 26 11:41:46 PST 2004 [...] radeonfb_pci_register BEGIN radeonfb: ref_clk=2700, ref_div=12, xclk=27500 from BIOS radeonfb: probed DDR SGRAM 65536k videoram radeon_get_moninfo: bios 4 scratch = a00000a radeonfb: panel ID string: ?h?? radeonfb: detected DFP panel size from BIOS: 1x0 radeonfb: detected DFP panel size from registers: 1280x1024 radeonfb: ATI Radeon 9000 If DDR SGRAM 64 MB radeonfb: DVI port DFP monitor connected radeonfb: CRT port CRT monitor connected radeonfb_pci_register END [...] hStart = 680, hEnd = 960, hTotal = 1056 vStart = 482, vEnd = 501, vTotal = 522 h_total_disp = 0x4f0083 hsync_strt_wid = 0xa302a2 v_total_disp = 0x1df0209 vsync_strt_wid = 0x9301e1 post div = 0x8 fb_div = 0x59 ppll_div_3 = 0x30059 ron = 828, roff = 19684 vclk_freq = 2503, per = 703 Console: switching to colour frame buffer device 80x30 I've seen some radeonfb patches floating around, but my impression was that 2.6.2-rc2 should work. If anyone has something for me to try, I'd be happy to give it a spin. Otherwise I guess I'll try to figure out what that debugging output is telling me.
