Could be, but my /proc/fb is empty.

It seems to!

At least, I could log in now. At first I thought I did something wrong, but the xdm login screen looks normal now, not white anymore!

Anyway, there is still a big problem though, my 3D seems broken:

goemon:~> glxgears
Radeon DRI driver:
        Compatibility mode for DRM driver version 1.1.1
        TCL will be disabled, expect reduced performance
        (prefer DRM radeon.o 1.3.x or newer)
        disabling TCL support
glxgears: radeon_ioctl.h:168: radeonAllocCmdBuf: Assertion `rmesa->dri.drmMinor >= 3' failed.

The XFree86.0.log seems just fine. (Yep, it starts with
XFree86 Version 4.2.0 (DRI trunk) / X Window System
There are no errors there.

By the way, I saw this:

(II) RADEON(0): AGP Fast Write disabled by default

What is AGP Fast Write? I saw in my BIOS an option to turn this on. Is this useful?

One very good thing: it seems that the ghosting is a bit less now! I couldn't test with openGL programs (which caused the worst ghosting effects), but it seems that it is a bit less now... (dragging windows around is still causing some of the ghosting though...))

It's 24 planes.

Well, I don't need fb anyway.

Do I have to put that in the driver section?
I did so, but:

(II) RADEON(0): Using hardware cursor (scanline 4808)
(WW) RADEON(0): Option "HWcursor" is not used

According to my XFree86 log.
Note that the first line was also already in my original log, with the 4.2.1. drivers from Debian.

Grtjs, Manuel
