Does the kernel framebuffer work? In that case, there is a fallback option "UseFBDev", that will not attempt to program the hardware, other then the accel registers. > ====================================== > (II) Loading sub module "ramdac" > (II) LoadModule: "ramdac"(II) Module "ramdac" already built-in > (II) do I need RAC?

Other then the UseFBDev option. I hope to have a more complete mode setting code soon, based on more recent information I received from SMI; information about the 502 clocks, and the differences with earlier releases, that are not clearly documented in the pdfs available at ftp.siliconmotion.com. > Best regards, > Christian Paulo _______________________________________________ xorg mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/xorg
