Granted by blosomax to use for
Maqeia
....for which we are mostly grateful!!!!

I have bumblebee working on my mageia 1 installation.
NB: bumblebee is an nvidia-optimus controller for linux, allowing you to run
apps on your nvidia card, instead of the intell one. see
https://github.com/Bumblebee-Project
NOTE THIS WILL DISABLE YOUR 3D EFFECTS FOR YOUR INTEL CARD.
To re-enable 3d on the intel card, use Mageia Control Center Choose: Hardware ->
Set up the graphical server, which will break the nvidia 3d.

Steps (thanks to bumblebee team, and Jaron Vietor who posted this
http://forum.mandriva.com/en/viewtopic.php?f=35&t=135018#p850742 on
the mandriva forums)
NB: You will need;
- to be able to edit files as root user
- to install git (details below, you may skip this if you know how to install
bumblebee without it)
- to install virtualGL (details below)

Notes on code (below) (Read this only if your not used to using terminal or
konsole)
- All non gui code is bash script used in a linux terminal like konsole.
- To open a terminal: Find "konsole" in your applications launcher
- To run commands as root user type: su [enter], and enter you root password.
(to leave root user mode type: exit [enter].
- Code here can then be simply copied and pasted into your terminal

-0: Backup your working xorg.conf file
- As root:
Code: Select all
cp /etc/X11/xorg.conf /etc/X11/xorg.conf.intel


-1: Install the nvidia drivers using the mageia configuration tool. (You may
need to setup you Mageia repositories)
- Open: Mageia Control Center
- Choose: Hardware -> Set up the graphical server
- Click: Graphic Card and select Nvidia -> GeForce model [GeForce 400 series
and later, or GeForce 6100 to GeForce 360]
- You should get a "There is a proprietary driver availabe... Do you wish to
use it?" Select Yes
- Allow Mageia to install all the drivers, and select ok to the settings
screen.
- DO NOT TEST!
- Select Quit, and Yes to "Keep the changes?"

!!! Do NOT restart your computer !!!
-2: Disable nvidia driver (it will not work at this stage)
- Copy the new xorg.conf file and save as xorg.conf.nvidia
As root:
Code: Select all
mv /etc/X11/xorg.conf /etc/X11/xorg.conf.nvidia

- Copy old conf back as main
As root:
Code: Select all
cp /etc/X11/xorg.conf.old /etc/X11/xorg.conf


RESTART YOUR COMPUTER


-3 Install virtualgl
- Download virtual: http://www.virtualgl.org I used
http://sourceforge.net/projects/virtualgl/files/VirtualGL/2.2.1/ and
chose VirtualGL-2.2.1.x86_64.rpm
- Install. Double-click downloaded rpm

-4: Install git (You may need to setup you Mageia repositories)
(you may skip this if you know how to install bumblebee without it)
- As root:
Code: Select all
urpmi git


-5 Install bumblebee using git
- As root:
Code: Select all
git clone
git://github.com/Bumblebee-Project/Bumblebee.git

This should create a Bumblebee folder in your current directory, before we
install we need to make some modifications to the install file.
- Edit Bumblebee/install, and comment out lines like the following ( As
bumblebee does not know of our distro.)
Code: Select all
   
  #install_step determinedistro    "" "precheck build install postconfig"
  #install_step "$DISTRO/setvars"  "" "precheck build install postconfig"
  #install_step "$DISTRO/checkdependencies" "Checking dependencies" precheck
  #install_step "$DISTRO/configure" "" postconfig

- Install As root:
Code: Select all
cd Bumblebee;./install

- Add users to the bumblebee group.
As root:
Code: Select all
usermod -a -G bumblebee YOURUSERNAME


-6 Modify bumblebee.conf
NB: Replace "lib64" with just "lib" if you are using a 32 bit OS
- As root edit /etc/bumblebee/bumblebee.conf, and add to the bottom
# My args
LD_LIBRARY_PATH="/usr/lib64/nvidia-current"
X_DAEMON="/etc/X11/X"
X_LD_LIBRARY_PATH="/usr/lib64/xorg"

EG As root:
Code: Select all
echo "# My args" >> /etc/bumblebee/bumblebee.conf
echo "LD_LIBRARY_PATH=\"/usr/lib64/nvidia-current\"" >>
/etc/bumblebee/bumblebee.conf
echo "X_DAEMON=\"/etc/X11/X\"" >> /etc/bumblebee/bumblebee.conf
echo "X_LD_LIBRARY_PATH=\"/usr/lib64/xorg\"" >> /etc/bumblebee/bumblebee.conf


-6 Modify the xorg.conf.nvidia in /etc/bumblebee directory
NB: If your unsure of the busid for your nvidia card try
Code: Select all
lspci -d 10de: -n
| grep '030[02]:' | cut -d' ' -f1

NB: The busid will probably be "01:00:0"

- Modify /etc/bumblebee/xorg.conf.nvidia:
Add: BusID "01:00:0", and Option "AddARGBGLXVisuals", to device section.
Remove: The whole files section
So /etc/bumblebee/xorg.conf.nvidia should look like
Code: Select all
Section "ServerLayout"
    Identifier "Layout0"
    Option "AutoAddDevices" "false"
EndSection

Section "Device"
    Identifier "Device1"
    Driver "nvidia"
    VendorName "NVIDIA Corporation"
    BusID "01:00:0"
    Option "NoLogo" "true"
    Option "UseEDID" "false"
    Option "ConnectedMonitor" "DFP"
    Option "AddARGBGLXVisuals"
EndSection


-7 Test:
- Open 2 terminals, 1 as root and 1 as your normal user.
- In the root terminal, start the bumblebee service:
Code: Select all
bumblebee
-d

- In the user terminal test an app:
Code: Select all
optirun kwrite

- The root terminal should show the output of starting the nvidia xorg conf,
and kwrite should launch from the user terminal.
- Press cntrl-c to kill the bumblebee service in the root terminal.
- To start bumblebee in the normal way as a
service:
Code: Select all
/etc/init.d/bumblebee start

- To start at boot use the Mageia drakxservices tool. Mageia Control Center
-> System -> Manage System services by ena ...

-8 To det the intel glx drivers working again (which will break the nvidia 3d
drivers)
- Open: Mageia Control Center
- Choose: Hardware -> Set up the graphical server
- Choose:All the default options Mageia gives
- Select Quit, and Yes to "Keep the changes?", REBOOT

-8 To det the intel nvidia drivers working again (which will break the intel
drivers)
Redo steps 1 & 2

Maybe someone could post how to use Section "path" in the nvidia xorg.conf so
bumblebee can load the nvidia 3d drivers/modules?

Powersave: How to turn off the nvidia card to save power, using acpi_call.
Note: The above bumblebee installation does not turn off the nvidia card when
it's not being used which can use up a lot of power just sitting there doing
nothing, I got switching the card on and off working in the following way.
WARNING: Turning the card off means you will need to restart before bumblebee
optirun can work again.

Steps (see, and thanks to, the team at
http://linux-hybrid-graphics.blogspot.com/)
NB: You will need;
- to be able to edit files as root user
- to install git (details below, you may skip this if you know how to install
acpi_call without it)

Notes on code (Read this only if your not used to using terminal or konsole)
- All non gui code is bash script used in a linux terminal like konsole.
- To open a terminal: Find "konsole" in your applications launcher
- To run commands as root user type: su [enter], and enter you root password.
(to leave root user mode type: exit [enter].
- Code here can then be simply copied and pasted into your terminal

-1 Install git. (If you haven't already)
As Root
Code: Select all
urpmi git


-2 Install acpi_call
As Root
Code: Select all
git clone https://github.com/mkottman/acpi_call.git
cd acpi_call
make
insmod acpi_call.ko


-3 Find your machines parameters
As Root
Code: Select all
chmod +x test_off.sh
./test_off.sh

You should get a list of tries like this
Trying \_SB.PCI0.P0P1.VGA._OFF: failed
Trying \_SB.PCI0.P0P2.VGA._OFF: failed
Trying \_SB_.PCI0.OVGA.ATPX: failed
Trying \_SB_.PCI0.OVGA.XTPX: failed
Trying \_SB.PCI0.P0P3.PEGP._OFF: failed
Trying \_SB.PCI0.P0P2.PEGP._OFF: failed
Trying \_SB.PCI0.P0P1.PEGP._OFF: failed
Trying \_SB.PCI0.MXR0.MXM0._OFF: failed
Trying \_SB.PCI0.PEG1.GFX0._OFF: failed
Trying \_SB.PCI0.PEG0.GFX0.DOF: failed
Trying \_SB.PCI0.PEG1.GFX0.DOF: failed
Trying \_SB.PCI0.PEG0.PEGP._OFF: failed
Trying \_SB.PCI0.XVR0.Z01I.DGOF: failed
Trying \_SB.PCI0.PEGR.GFX0._OFF: works!

The line that ends with "works!" is the one you want.
Using the example above I can now;
-turn the nvidia card off
As root
Code: Select all
echo '\_SB.PCI0.PEGR.GFX0._OFF' > /proc/acpi/call

-turn the nvidia card on
As root
Code: Select all
echo '\_SB.PCI0.PEGR.GFX0._ON' > /proc/acpi/call


-4 testing
Unplug the power and look at your battery power availabe.
Code: Select all
acpi

Repeat turning your nvidia card off and on
As Root
Code: Select all
acpi
echo '\_SB.PCI0.PEGR.GFX0._OFF' > /proc/acpi/call
sleep 3; acpi
echo '\_SB.PCI0.PEGR.GFX0._ON' > /proc/acpi/call
sleep 3;acpi

You should see a difference in battery life of 1-3 hours. The "sleep 3" is to
give the system time to update the battery drain, and useage.

-5 (Optional) Create your own powersaving script
Below is my script example, copy into a file called powersave_custom
Code: Select all
#!/bin/bash

USEAGE="useage: ${0##*/} [stop,start]
help:   Turns off/on custom power saving
requrs: /etc/acpi/call/acpi_call.ko
Note:   Root users only
"

# Check user is root
if [ "$(whoami)" != "root" ]
then
  echo -e "${USEAGE}" > /dev/stderr
  exit 0
fi

# Check acpi_call module is loaded
if ! lsmod | grep -q acpi_call
then
  # Check module exists
  if [ ! -e "/etc/acpi/call/acpi_call.ko" ]
  then
    echo -e "${USEAGE}" > /dev/stderr
    exit 0
  else
    # Install acpi_call module
    insmod /etc/acpi/call/acpi_call.ko
  fi
fi

# Show battery useage before
echo "Before switch `acpi`"

if  echo "${1}" | grep -qEi "start"
then

  ##############################################################
  # HERE you can put whatever code you want to run to save power
  ##############################################################
  /etc/init.d/wine stop > /dev/null 2>&1
  /etc/init.d/bumblebee stop > /dev/null 2>&1
  echo '\_SB.PCI0.PEGR.GFX0._OFF' > /proc/acpi/call

elif echo "${1}" | grep -qEi "stop"
then

  ##############################################################
  # HERE you can put whatever code you want to run for full power
  ##############################################################
  /etc/init.d/wine start > /dev/null 2>&1
  /etc/init.d/bumblebee start > /dev/null 2>&1
  echo '\_SB.PCI0.PEGR.GFX0._ON' > /proc/acpi/call

else
  echo -e "${USEAGE}"
  exit 1
fi

# Wait a few seconds for power usage to update
sleep 3
# Show battery useage before
echo "After switch `acpi`"


As Root
Code: Select all
cd ..
mv acpi_call/ /etc/acpi/call
cp powersave_custom /usr/sbin/powersave_custom
chmod +x /usr/sbin/powersave_custom

To run As Root
Code: Select all
powersave_custom start
powersave_custom stop

NB: You may want to put this script in your "Power Management Profiles"
"Run Script" -> powersave_custom start

Bumblebee should simply be added to the repos like it is in Mandriva. It would make the process of installation a ton easier and most laptops come with optimus on them now, so it's not a minor problem and should not be treated as such.

Please, please, please add bumblebee to the repositories in Mageia 2. This is the only thing stopping me from migrating.

Hi!

Bumblebee packages are available at (non-official spanish) Blogdrake repositories here
http://blogdrake.net/blog/drakedalfa/bl ... ftp-x86_64

But in my case I'd like to use only Nvidia driver/card. When I configure nvidia driver, both nouveau or propietary, at reboot system stops without finish with this message:

Code: Select all
Failed to start Wait for Plymouth Boot Screen to Quit
See 'systemctl status plymouth-quit-wait. service' for details


I think while xserver get configured for nvidia, system it's starting for Intel card but not sure.

Did open this thread some days ago
viewtopic.php?f=23&t=4073
but no answer. Did search a lot the forum looking for solution but did'nt found nothing.

It's not possible to use just Nvidia card on hybrid systems?

Regards,
Colegota
