Bug#586312: re

[Martin Kovarik <v.merlin@seznam.cz>]

Hi,

the problem missed sometime in the past. (I've been using fglrx)  X
server didn't crash - I can normally work after closing the issue 3D
application. 

I'm using Debian "testing" now. There are this version of xorg
installed:

        aptitude show xserver-xorg-core | grep Verze 
                Verze: 2:1.7.7-11
        aptitude show xserver-xorg-video-radeon | grep Verze
                Verze: 1:6.13.1-2+squeeze1

To enable Kernel Modesetting active in Xorg.0.log I have to add string
"radeon" to /etc/modules. In this case it seems 3D acceleration works
all  right (fgrlx is still better) Xorg.0.log says :
 (II) [KMS] Kernel modesetting enabled.

If I'll don't write "radeon" in /etc/modules I can see this in
Xorg.0.log:

(EE) RADEON(0): [dri] RADEONDRIGetVersion failed because of a version
mismatch.
[dri] This chipset requires a kernel module version of 1.17.0,
[dri] but the kernel reports a version of 2.0.0.[dri] If using legacy
modesetting, upgrade your kernel.
[dri] If using kernel modesetting, make sure your module is
[dri] loaded prior to starting X, and that this driver was built
[dri] with support for KMS.
[dri] Disabling DRI
Of course, in this case acceleration is off.
On http://www.x.org/wiki/radeonBuildHowTo#Kernel-basedModeSetting this
is explained like as KMS is not enabled before X started. So I don't
know if my solution is all right.
