Your English is great - better than my French! I can say one phrase and that's it.
Thanks for your help, but I'm afraid it didn't work. I tried changing boardname and driver in my xorg.conf to match yours, but then it just booted into text mode. So I used Sax2 to reset it back to the default Framebuffer.
Maybe its because I used these instructions:
And got the drivers from YaST instead of installing them myself.
How do I manually install them? And doesn't that mean I have to recompile the kernel every time I update the drivers, or something?
