Hello,
I got a used PCIe Radeon X1300 (RV516) off ebay for the s-video output
to use with an old tv that only has component, composite, and s-video
inputs and I need a working framebuffer. When I power on the PC the
manufacturer's logo comes on (with black borders on the sides), then
GRUB2 comes on just fine but I can only get a working VGA text console.
If I load the radeon drm driver I get a framebuffer console but with
horizontal green lines at 1024x768 res (s-video's max). If I lower the
resolution the lines get redder until at 640x480 the whole screen turns
magenta. I suspect the card is bad but I wanted to get your opinions first.
I tried booting from several live CDs and they all have the same
problem. I also tried a WinPE CD and that one seems to work fine but I
suspect is because it uses the boot resolution and never sets it, just
like the vga console.
I tried to load the vesafb, uvesafb, radeonfb, and the simple
framebuffer driver but none of them work, I get a black screen or the
text vga console if I enable it. And the kernel log shows nothing about
related to it. If I compile them as module the module loads without
error but I don't get a framebuffer and the log doesn't show anything.
