Hi Fred :)

this issue doesn't touch Debian stable. It starts with Debian testing
and is continued with Debian derivatives such as Ubuntu and Mint.

Yes, the xorg.conf is switched at startup. For Debian and Debian
derivatives take care about the lexical order in rcS.d
For Arch Linux the order when it gets started is settled
in /etc/rc.conf.

spinymouse at oz:~$ ls /media/maverick/etc/rcS.d
README  S13pcmciautils  S25brltty  S37apparmor  S47lm-sensors
S55urandom  S69switch_xorg.conf  S70x11-common
spinymouse at oz:~$ grep DAEMONS /mnt/archlinux/etc/rc.conf
# DAEMONS
DAEMONS=(69switch_xorg.conf hwclock syslog-ng !network !netfs crond
acpid dbus networkmanager rtirq)

:D You own a super expensive board for industry?

GeForce 7200 GS does work for a while in slow motion performance mode,
but after some minutes of using KDE4 with 3D crap, I need to use the
reset button. I got such a setup for a vanilla install of Mint Lisa KDE
64-bit.

Hahaha, I dropped GNOME3 on my machine, use Xfce now, but tried to give
KDE4 a chance. A KDE session for Mint Lisa won't start anymore, since I
installed the proprietary driver and Xfce on Mint Lisa comes with mouse
cursors from KDE, the selected mouse cursors for Xfce are ignored.

Ubuntus Studio Oneiric and Arch Linux are running Xfce only. Suse 11.2
and Edubuntu Maverick still run GNOME2.
