Hello, When I installed the 2.4.21 kernel-image, I gave the radeonfb a try. I have an IBM X31 with a Radeon Mobility M6 LY (according to lspci), and I really liked the console with the framebuffer. (I liked it so much that I started to learn screen.)
However, I was also quite interested in getting cpufreq to work, so yesterday I pulled the source for kernel 2.6-test2 from the unstable archive and I have been building kernels since. cpufreq appears to be working now (with apm), but I have lost my nice framebuffer. When the machine starts, it loads the framebuffer and spits out some information (from dmesg): > radeonfb_pci_register BEGIN > PCI: Found IRQ 11 for device 0000:01:00.0 > PCI: Sharing IRQ 11 with 0000:00:1d.0 > PCI: Sharing IRQ 11 with 0000:02:00.0 > PCI: Sharing IRQ 11 with 0000:02:01.0 > radeonfb: ref_clk=2700, ref_div=60, xclk=14400 from BIOS > radeonfb: probed DDR SGRAM 16384k videoram > radeon_get_moninfo: bios 4 scratch = 1000044 > radeonfb: panel ID string: 1024x768 > radeonfb: detected DFP panel size from BIOS: 1024x768 > radeonfb: ATI Radeon M6 LY DDR SGRAM 16 MB > radeonfb: DVI port LCD monitor connected > radeonfb: CRT port no monitor connected > radeonfb_pci_register END Also, lsmod shows it. But I don't think anything really happens to the screen. It seems the framebuffer module is loaded, but it isn't doing anything. I have grepped around for fbset under /etc and /lib/modules hoping to find where that is happening when the 2.4.21 kernel loads, but I cannot find anything. I have looked at the output of fbset under both kernels and they look similar, only rgba and the LineLength are different. lpa:~# diff k2.4.fbseti k2.6.fbseti 6c6 < rgba 8/0,8/0,8/0,0/0 --- > rgba 6/0,6/0,6/0,0/0 10c10 < Name : Radeon M6 LY --- > Name : M6 LY 18c18 < LineLength : 1024 --- > LineLength : 0 There are no video append statements in lilo.conf. Can anyone tell me where to look in order to understand how the framebuffer is started in the 2.4.21 kernel, so I can try to replicate it in my 2.6? Thanks a lot. Brian
