Installing ATI 9200SE and X -- Guidance appreciated
I'm trying to install X. It seems that I have to do quite a bit of configuration before it will work, and as it seems somewhat daunting I'd appreciate any advice you can give:
1: My setup: Gentoo with a Linux kernel 2.6.15. The graphics card is an ATI Radeon 9200SE. The processor is a 64 bit Athlon.
2: Having installed X I get errors complaining about missing drivers when I run it:
(==) Using default built-in configuration (53 lines)
(EE) Failed to load module "ati" (module does not exist, 0)
and indeed "locate ati.ko" yields nothing. I went to the kernel source and under the configuration tool there is an option that produces a module called radeonfb.ko. This sounds like a driver but I'm not 100%cert. I compiled it, and now I have to try to persuade X to use it.
3: Looked on the X website. I decided that as I'm a newbie to all this I'd use a configuration tool: xorgconfig. It asks me such questions as the vertical refresh and horizontal sync rates of the monitor. How do I find those out?
I can throw a knoppix disk at the machine and it runs happily, albeit probably in 32 bit mode. Presumably it auto-detects or successfully guesses the monitor settings. Is there a way I can find out what it's using?
4: Regarding the correct driver or drivers for the card, I looked to see what modules Knoppix loads. It has radeon.ko but no ati.ko or radeonfb.ko, hey I wasn't expecting to see something I'd recognise :^). It also lists drm.ko (with a comment that it's used by radeon), agpgart.ko and amd64_agp.ko which seemed kinda relevant. But I don't know what these actually do.
Is there anyone out there with a similar graphics card and an AMD64 bit processor? What are your settings?
I make a lousy computer user: I want to understand _why_ it works!
