Subject: [gentoo-user] switching between "nvidia / nouveau" drivers

1 I'm trying to prevent next disaster with nvidia driver/kernel combination.
2 I'm running "nvidia" driver and installed "nouveau" as module. If for any reason nvidia or nouveau will stop working I want to just run a sript and use other one.
4 Here is my configuration:
6 cat /etc/modprobe.d/blacklist.conf
7 blacklist nouveau
9 cat /etc/X11/xorg.conf
10 Section "Device"
11 Identifier "Nvidia card"
12 Driver "nvidia"
13 EndSection
15 eselect opengl list
16 Available OpenGL implementations:
17 [1] nvidia *
18 [2] xorg-x11
20 In order to switch it to "nouveau" I would need to unload the nvidia module, but I can not do it when it is in use so I need to stop "xdm" first, am I correct?
22 /etc/init.d/xdm stop (X crashes at this moment)
23 modprobe -r nvidia
24 mv /etc/modprobe.d/blacklist.conf /etc/modprobe.d/blacklist.conf_backup
25 mv /etc/X11/xorg.conf /etc/X11/xorg.conf_nvidia
26 eselect opengl set xorg-x11
27 modprobe nouveau
28 mv /etc/X11/xorg.conf_nouveau /etc/X11/xorg.conf
29 /etc/init.d/xdm start (at this moment I should have login screen)
31 Did I miss anything? Will it work if I put it into a bash script?
