Bumblebee on a Lenovo T440p [NVidia GT 730M] with XUbuntu/Ubuntu 17.10

In this guide, I'll help you, step by step, to set up bumblebee on a laptop with NVidia Optimus. Bumblebee is a daemon program that aims to offload programs to the discrete GPU at the user's discretion. I have tested this solution thoroughly on a Lenovo T440p, which has a GT 730M inside it; at least on some models. It is highly likely that bumblebee can be made to work in exactly the same way on other laptops, but as I have not tested this, this is experimental. I will make notes where I can to provide compatibility for other machines, hopefully from comments of readers.

Also, and I think this is important. I was working with a clean, fresh install of Ubuntu 17.10. Any tinkering you may have done previous to trying this guide may interfere with the steps presented herein. I recommend you undo them or install afresh; or you're a really advanced user and can deal with massaging this guide into your existing system. Anyway, onwards ...

1. Install a fresh copy of Ubuntu 17.10

Tada!

2. Blacklist nouveau

nouveau is the open-source NVidia graphics driver. It interferes with what we're going to try to do, which is to use the proprietary drivers, so we have to make sure the kernel doesn't auto-load it.

Create the file /etc/modprobe.d/blacklist-nouveau.conf and put this inside it:

blacklist nouveau

Now rebuild your ram-disk so that the changes are picked up and the ram-disk doesn't have the modules in it:

$ sudo update-initramfs -u
update-initramfs: Generating /boot/initrd.img-4.13.0-21-generic
$


3.  Set your ACPI interface.

In earlier versions of Ubuntu, the Kernel was such that this wasn't necessary. On newer Kernels, however, this is necessary, or your card cannot be controlled by bbswitch.

Edit the /etc/default/grub file and add acpi_osi=Linux to the kernel parameters, so that it looks like this:

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX="acpi_osi=Linux"

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

Note: Output above is truncated.

Note: Some people have also reported success with acpi_osi=\"!Windows 2013\", but I haven't had this succeed. In fact, it just made my laptop go funny where I could no longer shut-down correctly.

Note: u/andrewschott has noted that on Dell Inspiron 5000 series (5577, specifically), the string acpi_osi=! acpi_osi=\"Windows 2009\" is required to make bumblebee work. Please refer to his blog entry for more details.

Update the boot-loader:

$ sudo update-grub
Generating grub configuration file ...
Warning: Setting GRUB_TIMEOUT to a non-zero value when GRUB_HIDDEN_TIMEOUT is set is no longer supported.
Found linux image: /boot/vmlinuz-4.13.0-21-generic
Found initrd image: /boot/initrd.img-4.13.0-21-generic
done

4. Activate intel drivers for your integrated GPU

I know what you're thinking: "We're trying to get the discrete GPU working, not the integrated one!" Although it doesn't work without this. If the intel driver is not driving your integrated Intel GPU, then the bumblebee method won't work. You'll get GLX errors left, right and centre.

Interestingly, for some reason, 17.10 uses the vesa driver to drive the integrated Intel GPU by default. Why? No idea; 16.04 loaded the intel driver by default. That might be something I'll puzzle out in another post. For now let's just make it use intel.

You might already have this directory, but let's make it if you don't:

$ sudo mkdir -p /etc/X11/xorg.conf.d
$

Now edit the file /etc/X11/xorg.conf.d/20-intel.conf and put this inside it:

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod" "sna"
   Option      "TearFree" "true"
EndSection

What this does is actually twofold. It enables intel as the driver for your integrated GPU, and also enables TearFree, which is Intel's term for V-Sync. You'll most-likely want V-Sync. I recommend it.

5. Reboot

Yes, you have to. We need the new ram-disk to be booted with the new parameters.

$ sudo reboot

6. Install bumblebee and friends

We're going to install bumblebee, but we're going to override the default driver that bumblebee wants to install. First of all, update your package list:

7. Update the bumblebee configuration

We need to configure bumblebee to point to our new drivers. Edit /etc/bumblebee/bumblebee.conf and make the highlighted changes, such that it looks like this:

# Configuration file for Bumblebee. Values should **not** be put between quotes

## Server options. Any change made in this section will need a server restart
# to take effect.
[bumblebeed]
# The secondary Xorg server DISPLAY number
VirtualDisplay=:8
# Should the unused Xorg server be kept running? Set this to true if waiting
# for X to be ready is too long and don't need power management at all.
KeepUnusedXServer=false
# The name of the Bumbleblee server group name (GID name)
ServerGroup=bumblebee
# Card power state at exit. Set to false if the card shoud be ON when Bumblebee
# server exits.
TurnCardOffAtExit=false
# The default behavior of '-f' option on optirun. If set to "true", '-f' will
# be ignored.
NoEcoModeOverride=false
# The Driver used by Bumblebee server. If this value is not set (or empty),
# auto-detection is performed. The available drivers are nvidia and nouveau
# (See also the driver-specific sections below)
Driver=nvidia
# Directory with a dummy config file to pass as a -configdir to secondary X
XorgConfDir=/etc/bumblebee/xorg.conf.d
# Xorg binary to run
XorgBinary=/usr/lib/xorg/Xorg

## Client options. Will take effect on the next optirun executed.
[optirun]
# Acceleration/ rendering bridge, possible values are auto, virtualgl and
# primus.
Bridge=auto
# The method used for VirtualGL to transport frames between X servers.
# Possible values are proxy, jpeg, rgb, xv and yuv.
VGLTransport=proxy
# List of paths which are searched for the primus libGL.so.1 when using
# the primus bridge
PrimusLibraryPath=/usr/lib/x86_64-linux-gnu/primus:/usr/lib/i386-linux-gnu/primus
# Should the program run under optirun even if Bumblebee server or nvidia card
# is not available?
AllowFallbackToIGC=false


# Driver-specific settings are grouped under [driver-NAME]. The sections are
# parsed if the Driver setting in [bumblebeed] is set to NAME (or if auto-
# detection resolves to NAME).
# PMMethod: method to use for saving power by disabling the nvidia card, valid
# values are: auto - automatically detect which PM method to use
#         bbswitch - new in BB 3, recommended if available
#       switcheroo - vga_switcheroo method, use at your own risk
#             none - disable PM completely
# https://github.com/Bumblebee-Project/Bumblebee/wiki/Comparison-of-PM-methods

## Section with nvidia driver specific options, only parsed if Driver=nvidia
[driver-nvidia]
# Module name to load, defaults to Driver if empty or unset
KernelDriver=nvidia-384
PMMethod=auto
# colon-separated path to the nvidia libraries
LibraryPath=/usr/lib/nvidia-384:/usr/lib32/nvidia-384
# comma-separated path of the directory containing nvidia_drv.so and the
# default Xorg modules path
XorgModulePath=/usr/lib/nvidia-384/xorg,/usr/lib/xorg/modules
XorgConfFile=/etc/bumblebee/xorg.conf.nvidia

## Section with nouveau driver specific options, only parsed if Driver=nouveau
[driver-nouveau]
KernelDriver=nouveau
PMMethod=auto
XorgConfFile=/etc/bumblebee/xorg.conf.nouveau

8. Blacklist the new NVidia drivers, so that they don't get auto-loaded

Using the existing blacklist file installed by bumblebee, we're going to add a few lines to it. Edit /etc/modprobe.d/bumblebee.conf and make the following changes to it:

# This file is installed by bumblebee, do NOT edit!
# to be used by kmod / module-init-tools, and installed in /etc/modprobe.d/
# or equivalent

# do not automatically load nouveau as it may prevent nvidia from loading
blacklist nouveau
# do not automatically load nvidia as it's unloaded anyway when bumblebeed
# starts and may fail bumblebeed to disable the card in a race condition.

blacklist nvidia-384-updates

Update the ram-disk so that the excluded modules don't get put into it:

sudo update-initramfs -u
update-initramfs: Generating /boot/initrd.img-4.13.0-21-generic
$

Warning: The above is very important. Failing to update the ram-disk will result in an installation that doesn't enter Xorg correctly. If you've accidentally missed this step, you can enter single-mode from GRUB and recover that way.

9. Revert GL ld.so configurations to point to MESA ones

We need to use mesa by default, with bumblebee switching to NVidia at runtime if we tell it to. The nvidia-384 installer actually changes these to point to nvidia, so we need to revert this (some options may already be on the correct setting):

$ sudo update-alternatives --config i386-linux-gnu_gl_conf
There are 3 choices for the alternative i386-linux-gnu_gl_conf (providing /etc/ld.so.conf.d/i386-linux-gnu_GL.conf).

  Selection    Path                                      Priority   Status
------------------------------------------------------------
  0            /usr/lib/nvidia-384/alt_ld.so.conf         8604      auto mode

  2            /usr/lib/nvidia-384-prime/alt_ld.so.conf   8603      manual mode
  3            /usr/lib/nvidia-384/alt_ld.so.conf         8604      manual mode

Press <enter> to keep the current choice[*], or type selection number: 1
$ sudo update-alternatives --config x86_64-linux-gnu_egl_conf
There are 3 choices for the alternative x86_64-linux-gnu_egl_conf (providing /etc/ld.so.conf.d/x86_64-linux-gnu_EGL.conf).

  Selection    Path                                           Priority   Status
------------------------------------------------------------
* 0            /usr/lib/nvidia-384/ld.so.conf                  8604      auto mode

  2            /usr/lib/nvidia-384/ld.so.conf                  8604      manual mode
  3            /usr/lib/x86_64-linux-gnu/mesa-egl/ld.so.conf   500       manual mode

Press <enter> to keep the current choice[*], or type selection number: 3
update-alternatives: using /usr/lib/x86_64-linux-gnu/mesa-egl/ld.so.conf to provide /etc/ld.so.conf.d/x86_64-linux-gnu_EGL.conf (x86_64-linux-gnu_egl_conf) in manual mode
$ sudo update-alternatives --config x86_64-linux-gnu_gl_conf
There are 3 choices for the alternative x86_64-linux-gnu_gl_conf (providing /etc/ld.so.conf.d/x86_64-linux-gnu_GL.conf).

* 3            /usr/lib/x86_64-linux-gnu/mesa/ld.so.conf   500       manual mode

Press <enter> to keep the current choice[*], or type selection number: 3
$

Make our new selections active:

$ sudo ldconfig
$

10. Reboot

Yes, again.

$ sudo reboot

11. Test 

Right, onto the testing. First of all, out integrated Intel card should still be the default vendor:

$ glxinfo | grep 'OpenGL vendor'
OpenGL vendor string: Intel Open Source Technology Center
$

Test rendering on the integrated Intel card:

$ glxgears
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
303 frames in 5.0 seconds = 60.478 FPS
301 frames in 5.0 seconds = 60.050 FPS
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0"
      after 2661 requests (2661 known processed) with 0 events remaining.
$


All good!

Let's now do the same, but with the discrete NVidia card. Check the vendor for GL:

$ primusrun glxinfo | grep 'OpenGL vendor'
/usr/bin/primusrun: line 41: warning: command substitution: ignored null byte in input
OpenGL vendor string: NVIDIA Corporation
$

Cool, and let's try rendering on the NVidia card:

$ primusrun glxgears
/usr/bin/primusrun: line 41: warning: command substitution: ignored null byte in input
290 frames in 5.0 seconds = 57.944 FPS
300 frames in 5.0 seconds = 59.903 FPS
X Error of failed request:  BadDrawable (invalid Pixmap or Window parameter)
  Major opcode of failed request:  153 (DRI2)
  Minor opcode of failed request:  7 (DRI2GetBuffersWithFormat    )
  Resource id in failed request:  0x3c00002,
  Serial number of failed request:  2330
  Current serial number in output stream:  2330
primus: warning: dropping a frame to avoid deadlock
primus: warning: timeout waiting for display worker
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0"
      after 31 requests (31 known processed) with 0 events remaining.
$


Note: Don't worry about the errors in there. They do not affect the application and are some sort of a bug. I do not claim to understand the nature of this.

Everything works! Hopefully it does for you as well. Enjoy.

  4. hello,
    if primusrun glxgears is not giving you better fps than pure glxgear from intel ~around 60fps - what is the interest of having nvidia gpu here ?

    1. It's not giving more frames because of V-Sync. With V-Sync off, you would see a difference. Even with V-Sync on, the NVidia GPU can render a lot higher quality frame in the 1/60th of a second than the Intel card can, so there's a quality difference.
