| This howto describes how to use nvidia and nouveau drivers on the same computer and kernel.
| | {{PageNeedsUpdates}} |
| <br>
| |
| {{Fancynote|You must know how to install {{Package|x11-drivers/nvidia-drivers}} and {{package|x11-drivers/nouveau}} (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 <tt>/etc/boot.conf</tt>:
| |
| | |
| {{file|name=/etc/boot.conf|desc= |body=
| |
| 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 | <tt>boot-update</tt>]].
| |
| | |
| After boot-update has been run, you should have something like:
| |
| <console>
| |
| ###i## grep menuentry /boot/grub/grub.cfg | wc -l
| |
| 2
| |
| ###i## 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" {
| |
| </console>
| |
| | |
| == xcfgmaker deamon ==
| |
| | |
| <console>
| |
| ###i## mkdir /etc/X11/video/;
| |
| ###i## cd /etc/X11/video/;
| |
| ###i## nano 10-monitor.conf.nouveau # make default config for nouveau. or copy existing config…
| |
| ###i## nano 10-monitor.conf.nvidia # also for nvidia
| |
| </console>
| |
| | |
| Then create a new daemon. Edit the file <tt>/etc/init.d/xcfgmaker</tt>:
| |
| <syntaxhighlight lang="bash">
| |
| #!/sbin/runscript
| |
| | |
| # 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=$(cat /proc/cmdline | grep -e "nouveau.blacklist=" -e "nvidia.blacklist=")
| |
| display_mode_nvidia_exist=$(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;
| |
| else
| |
| 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;
| |
| fi
| |
| sleep 5
| |
| eend 0
| |
| else
| |
| ebegin "Xorg file missing. Exitting"
| |
| eend 0
| |
| fi
| |
| fi
| |
| | |
| } | |
| </syntaxhighlight>
| |
| | |
| Do not forget:
| |
| <console>
| |
| ###i## chmod +x /etc/init.d/xcfgmaker
| |
| ###i## rc-update add xcfgmaker boot
| |
| </console>
