I thought they contained the necessary stuff from Ani Joshi's rsync tree.

No big surprise as the fbdev driver doesn't have any hardware acceleration. > Also the screen is oddly "wrapped" on the rage II machine with the fbdev > driver: I can see the full screen but the virtual edge starts about 75% in, > instead of matching the physical edge, and then wraps around.

Use Option "fbdev" "/dev/fb1" for the second one etc. Michel -- Earthling Michel Dänzer (MrCooper) \ CS student and free software enthusiast Debian GNU/Linux (powerpc,i386) user \ member of XFree86 and The DRI Project ** Sent via the linuxppc-dev mail list.
