This howto describes how to use nvidia and nouveau drivers on the same computer and kernel.


You must know how to install NVIDIA Linux Display Drivers and x11-drivers/nouveau (package not on wiki - please add) (references at the end of the page). First, you need to configure your kernel and install nvidia drivers and nouveau. We assume that this stage is successfully passed.


The most important change: edit /etc/boot.conf:

boot {
	generate grub
	default "Funtoo Linux [nvidia]" 
	# or
	# default "Funtoo Linux [nouveau]"
	timeout 3 

color {
	normal cyan/blue
	highlight blue/cyan

display {
	#gfxmode 1280x800
	#font unifont.pf2

"Funtoo Linux [nvidia]" {
	kernel vmlinuz[-v]
	params += ro console=tty1 quiet <other standard boot options>
	params += nouveau.blacklist=true vga=791 # nouveau.blacklist=true is important
	# or
	# params += nouveau.blacklist=true video=uvesafb:1440x900-8,mtrr:2

"Funtoo Linux [nouveau]" {
	kernel vmlinuz[-v]
	params += ro console=tty1 quiet <other standard boot options>
	params += nvidia.blacklist=true # nvidia.blacklist=true is important

Next, run boot-update.

After boot-update has been run, you should have something like:

# grep menuentry /boot/grub/grub.cfg | wc -l
# grep menuentry /boot/grub/grub.cfg
menuentry "Funtoo Linux [nouveau] - vmlinuz-" {
menuentry "Funtoo Linux [nvidia] - vmlinuz-" {

xcfgmaker deamon

# mkdir /etc/X11/video/;
# cd /etc/X11/video/;
# nano 10-monitor.conf.nouveau # make default config for nouveau. or copy existing config… 
# nano 10-monitor.conf.nvidia # also for nvidia

Then create a new daemon. Edit the file /etc/init.d/xcfgmaker:

# by
# To be placed in /etc/init.d/
# Run Command: rc-update add xcfgmaker boot
   need localmount
   before xdm-setup
   before xdm
   before alsasound
   cmdline_display_mode_exist=$(cat /proc/cmdline | grep -e "nouveau.blacklist=" -e "nvidia.blacklist=")
   display_mode_nvidia_exist=$(ls /etc/X11/video/ | grep "10-monitor.conf.nvidia")
   display_mode_nouveau_exist=$(ls /etc/X11/video/ | grep "10-monitor.conf.nouveau")
   cmdline_display_mode=$(cat /proc/cmdline | awk -Fnvidia.blacklist= '{print $2}' | awk '{print $1}')
   if [ -n "$cmdline_display_mode_exist" ]; then
      if [ -n "$display_mode_nvidia_exist" ] && [ -n "$display_mode_nouveau_exist" ]; then
            #Choose the xorg file to be copied over
            if [ "$cmdline_display_mode" == "true" ]; then
               ebegin "Configuring X display with nouveau"
               cp /etc/X11/video/10-monitor.conf.nouveau /etc/X11/xorg.conf.d/10-monitor.conf
               eselect opengl set xorg-x11 >/dev/null 2>&1;
               ebegin "Configuring X display with nvidia"
               cp /etc/X11/video/10-monitor.conf.nvidia /etc/X11/xorg.conf.d/10-monitor.conf
               eselect opengl set nvidia >/dev/null 2>&1;
         sleep 5
         eend 0
         ebegin "Xorg file missing. Exitting"
         eend 0

Do not forget:

# chmod +x /etc/init.d/xcfgmaker
# rc-update add xcfgmaker boot
