I now have a configuration file for X that sort of works, using the fbdev device. But I can't get any color depth more than 8bpp to work. And also, the colors are messed up at 8bpp...I got some information elsewhere (http://sdb.suse.de/sdb/en/html/olh_ppc_framebuffer.html)which talks about how to change the color depth, but it apparently doesn't work. I gave my kernel the following parameter: video=aty128fb:vmode:10:cmode:16 But when I tried to use fbset to set the depth to 16, it complained: ioctl FBIOPUT_VSCREENINFO: Invalid argument
Looks like it's not aty128fb but OFfb in fact. With yaboot you need to encapsulate the video argument into append="..."
Unfortunately, using the r128 driver is not an option, as it consistently locks up the notebook (not just X, but the entire OS). Any suggestions?
You need either
Option "UseFBDev"
(requires aty128fb, recommended) _or_
Option "ProgramFPRegs" "off"
_or_
Option "PanelWidth" "800"
Option "PanelHeight" "600"
in the XF86Config Device Section.
