Problems with Radeon Framebuffer

Problems with Radeon Framebuffer

[Hanno Boeck]

I have Problems using the radeon Framebuffer on my Notebook. It is a Sony PCG-GR114MK with a Radeon Mobility.

Kernel shows the following message. It only works with vesa-framebuffer.

Feb 19 23:41:54 hannonb kernel: radeonfb: ref_clk=2700, ref_div=60, xclk=16600 from BIOS
Feb 19 23:41:54 hannonb kernel: radeonfb: panel ID string: 1024x768                
Feb 19 23:41:54 hannonb kernel: radeonfb: detected DFP panel size from BIOS: 1024x768
Feb 19 23:41:54 hannonb kernel: radeonfb: cannot map FB

Any ideas what I could do?

Did you have vesafb compiled in also (can tell by looking at the entire 
dmesg)? This would explain why radeonfb can't map the framebuffer 
memory. If so, try again without vesafb compiled in.

Not this this answers your question, but I can say that this card works
with vesafb by passing 'vga=834' to the kernel-- I do that on a laptop
with the same chip.  But if I enable the frame buffer using this method,
I can't use the radeon driver in XFree86.  But, the radeon driver isn't
stable enough for me so I don't mind not using it.  Haven't tried
XFree86 4.2 yet though (or radeonfb for that matter).

If I do that, my console is completely black!
I don't have a console any more. I can only run Xfree.

So that doesn't help either.

Btw, this is what lspci -v says about my graphics card:
