Make.conf/VIDEO CARDS/NVIDIA and Nouveau Driver Switching

From Funtoo
Jump to navigation Jump to search
   Important

This page needs updates to address the use of libglvd in Funtoo 1.4+

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

   Note

You must know how to install x11-drivers/nvidia-drivers and No results (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.

boot-update

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

   /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: 

root # grep menuentry /boot/grub/grub.cfg | wc -l
2
root # grep menuentry /boot/grub/grub.cfg
menuentry "Funtoo Linux [nouveau] - vmlinuz-2.6.32.71_p14-rh" {
menuentry "Funtoo Linux [nvidia] - vmlinuz-2.6.32.71_p14-rh" {

xcfgmaker deamon

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

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

   /etc/init.d/xcfgmaker 
#!/sbin/openrc-run

# by http://wiki.sabayon.org/index.php?title=HOWTO:_Create_a_boot_option_for_easy_dual_to_single_display_switching
# To be placed in /etc/init.d/
# Run Command: rc-update add xcfgmaker boot

depend()
{
   need localmount
   before xdm-setup
   before xdm
   before alsasound
}

start()
{

   cmdline_display_mode_exist=$(cat /proc/cmdline

Do not forget: 

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