[ 57.413734] [ERROR]Cannot access secondary GPU - error: XORG No devices detected.

[ 57.413772] [ERROR]Aborting because fallback start is disabled.

Sorry to bother but I feel I am close to having bumblebee work. maybe. hehe. So maybe someone can give me some advice?

I am using centos 6 as my distro of choice. We use it where I work.

I installed the nvidia binary blob install. Then using Samsagax's suggestion, I was able to fix the 3d in my intel card. :)

So all the nvidia files are where the installer put them except for the conflicting files which have been moved to:

/usr/lib/nvidia-bumblebee/libGL.so
/usr/lib/nvidia-bumblebee/libGL.so.1
/usr/lib/nvidia-bumblebee/libGL.so.290.10
/usr/lib64/nvidia-bumblebee/libGL.so
/usr/lib64/nvidia-bumblebee/libGL.so.1
/usr/lib64/nvidia-bumblebee/libGL.so.290.10
/usr/lib64/nvidia-bumblebee/xorg/modules/extensions/libglx.so
/usr/lib64/nvidia-bumblebee/xorg/modules/extensions/libglx.so.290.10

I guessed at the configure options...

./configure CONF_DRIVER=nvidia CONF_LDPATH_NVIDIA=/usr/lib64:/usr/lib CONF_MODPATH_NVIDIA=/usr/lib64/nvidia-bumblebee/xorg/modules

when I try to start bumblebeed, i get errors in my /var/log/messages file.

Feb 9 20:49:44 localhost bumblebeed[5985]: Invalid configuration: no driver configured.
Feb 9 20:50:35 localhost bumblebeed[6059]: Invalid configuration: no driver configured.
Feb 9 21:01:16 localhost bumblebeed[6258]: Switching method 'bbswitch' is available and will be used.
Feb 9 21:01:16 localhost bumblebeed[6258]: Invalid configuration: no driver configured.

Maybe my configuration file is missing something or I needed to configure with more options before make? Any help or advice would be awesome. All this graphics stuff is so new to me.

Hi,

i once enabled the acpi handle hack and bbswitch and didn't care about it a long time. Some days ago i noticed that my notebook runs hotter than usually. So i looked for the acpi-handle-hack and found out it stopped working.

kernel log says:
[21434.927730] acpi_handle_hack: No ACPI handle found for discrete video card

i have installed the 0.0.2 version.
any suggestions?

greetings

Valentin

Hi ,

After downloading bbswitch tar.gz and extracting it , I Tried to follow the instructions provided in the readme but I'm getting errors .

Could you please provide me with the exact instructions to execute for a successful installation I hope .

Thank you .

Hello Everyone,

i am running Fedora 17 with Kernel 3.4.5-2.fc17.x86_64 on a Lenovo IdeaPad Y570. On my way to disable the Nvidia graphics card i came upon this acpi-handle-hack to enable the bbswitch kernel module. So i downloaded and installed the acpi-handle-hack module. But, when loading the module nothing happens and dmesg says: "Machine does not need ACPI handle hack" :(.

Here are my module versions:
acpi-handle-hack, 0.0.1, 3.4.5-2.fc17.x86_64, x86_64: installed
bbswitch, 0.4.1, 3.4.5-2.fc17.x86_64, x86_64: installed

Any suggestions?

make[1]: *** [_module_/home/******/bbswitch-master] Error 2

Seems to be due to a grsecurity gcc plugin.

Hello,

I tried to install bbswitch on openSuse 12.1. After executing "make" (as normal user as well as su) I got the following error message:

make -C /lib/modules/3.1.9-1.4-desktop/build M="$(pwd)" modules
make: *** /lib/modules/3.1.9-1.4-desktop/build: Datei oder Verzeichnis nicht gefunden. Schluss.
make: *** [default] Fehler 2
(The second line is something like this: "File or directory not found")

If there are any ideas to solve this, they would be welcome...

Thanks,
hamiltonian

I get a 'kernel oops' when I try to load the bbswitch module. I cloned the repo and followed the build instructions but I get an error when I'm trying to load the module by issuing

sudo make load

What happens is that I get switched to a virtual console where some kernel messages are displayed. The system also becomes unresponsive so I can't save the message. However, looking at this: http://pastebin.com/F2uk0nNQ , someone seem to have had the same issue. I get the exact same message (I think). I will try to capture the message in a few days.

System:
ASUS U36SD (Mobile Intel HM65 Express, Intel Core i7 2620M, NVIDIA GeForce GT 520M, ...)
OS: Ubuntu 11.10
Kernel: 3.0.0-15-generic

I recently upgraded to linux 3.6 out of the testing repo in ArchLinux and now bbswitch won't power on and off the card.
I've come from a working bumblebee installation on linux 3.5 and seems that maybe something's changed in the acpi setup.

Here's my dmesg: http://pastebin.archlinux.fr/450067

I have nvidia and nouveau blacklisted and all combinations of bbswitch module options yield the same result.

Hello,

I installed bbswitch for openSuse from this repository:
http://download.opensuse.org/repositories/home:/frostmyname:/bumblebee3/openSUSE_12.1/
and I tried to use it as described in the Readme.md. When I try to turn the card off with

# tee /proc/acpi/bbswitch <<<OFF

it stays on. The suggestion is to unload the driver, but I do not know how this works. Maybe someone could give me a small hint how to do that?

Thanks in advance,

hamiltonian

During license review of packaging bbswitch for official Debian repository, we've found that there isn't an indication of what license that bbswitch is used. Could you please give a clear statement, like adding a COPYING/LICENSE to the source?

Thank you very much.

I've tried Ubuntu mainline kernel today, so basically this is quite untouched 3.9rc8, and I've seen this:

Is that something to worry about?

First of all I apologise if this is not the place to report this. If it's not, tell me where it is and I'll happily submit it there.

I have an Asus UL80VT with an Nvidia G210M. AFAIK, no Optimus (I have to manually switch between cards in Windows). After fresh install of Linux Mint 15 Cinnamon edition, the Fn+F5 and Fn+F6 shows OSD but the brightness is not changed, and the nvidia card is turned on draining battery.

I installed bbswitch and it successfully turns off the discrete card, but i can no longer adjust the brightness using the fn keys. The "showkey" command shows that the ACPI events are not detected. I tested again after uninstalling bbswitch and the events are detected correctly.

Manually running the 'sudo setpci -s '00:02.0' F4.B=XX' command changes the brightness, so I guess that the only problem is that the fn+F5 and fn+F6 keys presses are somehow "masked" by bbswitch.

Is there any way to be able to use them again?

The relevant information is below. Please let me know if you need more info. Thanks in advance!

Hi everyone,

I have some issues during my kernel updates: update-initramfs just don't want to end and I need to stop the process. This issue started in the same time than the bbswitch crash. I noticed a bbswitch crash when I boot my computer, when I try to shutdown it and when I try to install or reinstall bumblebee.

Hello, thanks for the work you've done with bumblebee and bbswitch.
I've got an ASUS NS53sv with a NVIDIA® GeForce® GT 540M. I run Ubuntu 11.10 64bit with kernel 3.0.0-15-generic., my versoin of Xorg is 1:7.6+7ubuntu7 and i have no nvidia driver installed (I just use bbswitch to turn-off the card, I don't need optirun).
I installed the module with DKMS and then i manually run the command sudo tee /proc/acpi/bbswitch <<<OFF. For the first time under linux the led which shows if the nvdia card is on is working, and that's really great!
But I have a really strange problem, as soons as i run the command my touchpad stops working (but a usb connected mouse works fine).
I can't explain this behaviour, could you help me maybe?

If it can help this is the output of dmesg | grep -C 10 bbswitch:

Thanks again for your great work!

Hi everyone,

Thanks for this great tool but i have a little issue.

tee /proc/acpi/bbswitch <<<OFF command works great. My card goes off.

But when i reboot my system and try to look my cards status with cat /proc/acpi/bbswitch it says cat: /proc/acpi/bbswitch: No such file or directory

I have to run

make
make load
tee /proc/acpi/bbswitch <<<OFF

again, to turn off the card. It's weird that i have to build again the bbswitch.

My system is Debian 6.0.5. And i'll be happy to share any required information.

i use lenovo y460
os: ubuntu 10.04 x86_64

i want to turn off the nvidia card because i find my screen flicker .

there are repeat line occur in xorg.0.log

when use acpi_call or bbswitch there something wrong in the kernel.log, i gusee there are another software want to use the nvidia card after i turn it off.

Hello,

I'm trying to get my two external monitors to work with my Asus X93SM laptop.

I've followed the instructions in README.md on the module options to turn the card on, but dmesg still says

bbswitch: disabling discrete graphics

I have no problems with running Bumblebee:

$ optirun glxspheres

works like a charm (about 75 times faster).

# tee /proc/acpi/bbswitch <<<OFF
# tee /proc/acpi/bbswitch <<<ON

also works: lshw detects the Nvidia card while ON, but not when I turn it OFF.

I've done the following:

# modprobe bbswitch load_state=1

# echo 'bbswitch load_state=1' >> /etc/modules && update-initramfs -u

After reboot:

$ dmesg | grep -C 10 bbswitch
[   11.508525] bbswitch: version 0.4.2

$ cat /proc/acpi/bbswitch 
0000:01:00.0 OFF

One other thing that I've noticed is that when I have additional monitor connected to my display port it comes on when I run anything using optirun. But it remains off when I run tee /proc/acpi/bbswitch <<<ON.

My laptop is Asus X93SM

$ uname -a
Linux asusx 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

I test longtime bumblebee+bswitch combination, but without succes - discrete card is always powered.
I have executed command "tee /proc/acpi/bbswitch <<<OFF"
but "cat /proc/acpi/bbswitch" always shows "ON"

i get disabled discrete graphics card only with switcheroo

HOW can i debug bbswitch and help you ?

My info already on launchpad (qx412).
Steps to reproduce:
run optirun something
check whether card on or off
when on, try to suspend with KDE suspend
optirun something is required, of you only simple turn on the card, suspend works

bbswitch creates the following trace back with the following system configuration:

If I try to make bbswitch with dkms I get this error

dkms: 2.1.1.2

Running Arch: kernel 3.7.4-1-ARCH

After updating to kernel vesion 3.7.4 I'm having the following issues:

• On boot, the card disactivates and then is instantly activated again. nvidia and nouveau are blacklisted, bbswitch is initialised with load_state=0. Bumblebeed is started as a system service.
  Log output: http://sprunge.us/IGL
  I noticed mentions of VGA switcheroo and nouveau in there, not sure why..
• When the lid of my laptop is shut, the card activates (this did not happen on 3.6 kernel versions) and then my laptop fan goes full blast and it gets very hot. On opening the lid the card stays activated. I have to restart the bumblebee daemon on reopening the lid via acpi's handler.sh which is not ideal.

The proc entry /proc/acpi/bbswitch is created with 0660 permissions, which doesn't allow my normal user to read it.

$ ls /proc/acpi/bbswitch
-rw-rw---- 1 root root 0 Jan 19 11:57 /proc/acpi/bbswitch

I built it with 0644, but is there some specific reason for 0660?

The dkms module is not loaded and manual loading with insmod causes a kernel panic.

A few months ago on my Lenovo y580 I used this hack to get my graphics card (gtx660m) working. Now that I updated to Raring bumblebee disappeared so I had to reinstall it. I installed but when I ran "optirun glxshperes" I get the error:

I set off to try installing the bbswitch hack but when I execute "sudo dkms install -m acpi-handle-hack -v 0.0.2" I get:

Consult /var/lib/dkms/acpi-handle-hack/0.0.2/build/make.log for more information.

Also from "cat /var/log/kern.log | grep -A5 bbswitch" I get a part:

API mismatch: the client has the version 310.14, but this kernel module has the version >304.84. Please make sure that this kernel module and all NVIDIA driver components >have the same version.

So could the 310 drivers be causing it? I installed them because I couldn't get it to work with the old ones.

All help is very much appreciated!

Hello, all!

First of all, I would like to thank everyone for the project, it is of real importance and I am really thankful for it. Keep up with the good job..

I am having some trouble with the whole disable-card and power management in Fedora 16.
My laptop is
The temperature is still high ( 65 º C with the card OFF and 78 º C and more with the card ON ) and sometimes the card is not really disabled on boot time, so I have to disable it manually. I compiled things from source following a tutorial found here http://fedoraforum.org/forum/showthread.php?t=272692

Did I miss something?

Anyway, here is some output that may be helpful..

In README.md, one can read:

For example, if you want to have bbswitch disable the card immediately when
loading the module while disabling the card on unload, load the module with:
# modprobe bbswitch load_state=0 unload_state=1

Should not it be:

For example, if you want to have bbswitch disable the card immediately when

I have above mentioned laptop with nvidia 5xx series graphic card of 1 GB. I followed the guide from here :
https://wiki.ubuntu.com/Bumblebee

but unfortunately the bbswitch command is not found on my computer ( it is not installed rather ).

I want to save my laptop battery since I rarely use the nvidia graphic card, kindly suggest something.

On video card that also have an audio output, the logs are spammed with hda-intel: spurious response when the card is disabled.

During enumeration of the devices, perhaps there is a way to restrict to the vga device only.

I need a machine for testing as I don't own a machine which has a nvidia card with audio (via HDMI?) output. You can check whether you've this output by running lspci -d10de: -nn. If you have two devices, it'll a PCI bus ID like 02:00.0 and 02:00.1.

Hi all, I have been using acpi_call to power off and on the discrete card on my laptop; lately, I tried bbswitch out, but it does not work.
I'm on Linux 3.2.1; these are the successful commands with acpi_call:

\_SB.PCI0.PEG.VID._PS3 and \_SB.PCI0.PEG.VID._OFF to disable the card, and \_SB.PCI0.PEG.VID._ON and \_SB.PCI0.PEG.VID._PS0 to enable it.

bbswitch reports the following on dmesg when being loaded and trying to disable the card:

[   15.234248] bbswitch: Found integrated VGA device 0000:00:02.0: \_SB_.PCI0.VID_

As it results, the discrete card is still on.

If you need more information to track the issue, please let me know.

Hey,

today I received official package updates for my Ubuntu Lucid 10.04 LTS 32-bit installation via repositories.

My current kernel version is 2.6.32-45-generic-pae
DKMS version is 2.1.1.2

However, I'm unable to install bbswitch-dkms module in kernel. After several failures I downloaded the source and tried compile the bbswitch-dkms package without success, even with all build dependencies installed.

According to /var/lib/dkms/bbswitch/0.5/build/make.log, building of DKMS module fails to the following message:

DKMS make.log for bbswitch-0.5 for kernel 2.6.32-45-generic-pae (i686)

make[1]: *** [default] Error 2
make[1]: Leaving directory "/var/lib/dkms/bbswitch/0.5/build"

This package (bbswitch-dkms) was acquired with the packages bumblebee and bumblebee-nvidia.

I have also tried installing bbswitch with command (At first, I unloaded the the module from kernel with command "rmmod bbswitch")

sudo make -f Makefile.dkms

mkdir -p '/usr/src/bbswitch-0.5'
cp Makefile bbswitch.c '/usr/src/bbswitch-0.5'
sed 's/#MODULE_VERSION#/0.5/' dkms/dkms.conf > '/usr/src/bbswitch-0.5/dkms.conf'
dkms build -m bbswitch -v 0.5

Error! DKMS tree does not contain: bbswitch-0.5
Build cannot continue without the proper tree.
make: *** [build] Error 2

Thus I have a partially broken DPKG.

With normal APT install procedures, the messages in terminal are

Removing old bbswitch-0.5 DKMS files...

Deleting module version: 0.5

completely from the DKMS tree.

I suspect that the key error message is in make.log and states:

I wish someone could figure this out...thank you.

Update 2013-03-16: Linux 3.9-rc1 finally fixed the bug, everyone using 3.9-rc1 or newer can drop the acpi-handle-hack. ~L
Update 2013-03-29: Linux 3.8.5 also got the fix, you do not need any patching yourself for that kernel and newer!

I had to disable the bbswitch module 'dkms remove bbswitch/0.6.0 --all' on Fedora 19 and reboot in order to get the nvidia module to load.

Before disabling it I would get error messages like "nvidia: probe of 0000:01:00.0 failed with error -1" when trying to load the build/load the nvidia module.

This all worked as advertised before upgrading from F18 on the 3.9.4-200 kernel. Currently using Fedora 19 with 3.9.4-300.

To be clear, bbswitch is loading on boot, which leaves this in dmesg:

/proc/acpi/bbswitch shows the card is off and the nvidia driver does not load automatically.

After disabling bbswitch and rebooting (dms remove bbswitch/0.6.0 -all) the nvidia driver will load automatically.

I was also getting lots of weird errors about being unable to load the module, not having a supported card, and other strange stuff prior to disabling bbswitch when trying to run bumblebee-nvidia --debug --force. nouveau was blacklisted and not loaded. Now that it is built it seems I can manually load it if I turn the card on first.

Adding either of these to /etc/modprobe.d/bbwitch.conf and running dracut -f had no affect on the message above:
options bbswitch load_state=1 unload_state=1
options bbswitch load_state=-1 unload_state=-1

Hi!
I use Fedora 19 (64 bit), bumblebee-nvidia (from repo), kernel 3.9.4-300. ASUS U35Jc (Core i3 + GT 310M)
Every time when system starts I get notification about problem (from default Fedora's bugreport utility). optirun works correctly.

There are only next information:
WARNING: at drivers/pci/pci.c:1393 pci_disable_device+0x84/0x90()
A kernel problem occurred, but your kernel has been tainted (flags:PFO). Kernel maintainers are unable to diagnose tainted reports. Tainted modules: bbswitch.

Screen attached.

Is this real problem with bbswitch module? If it is a problem I can get some useful info for you (only talk to me how to get it). I am C++ linux programmer, I know how to get core dump for applications, but never work with kernel modules and don't know how to get call stack from them.

Hi!

My problem like here #26

Fedora 18,
Kernel 3.7.7-201.fc18.x86_64
bbswitch, and acpi-handle-hack lates from git.

I added my laptop model to acpi-handle-hack.c:

•   || dmi_match(DMI_PRODUCT_VERSION, "Lenovo G580")
  

•   || dmi_match(DMI_PRODUCT_VERSION, "Lenovo G480")
  

But i get error: No ACPI handle found for discrete video card.

Tarboll from http://lekensteyn.nl/files/get-acpi-info.sh here http://rghost.ru/43930848

Up to kernel 3.3.7-1 I was able to use bumblebee and bbswitch with my Asus U36SD laptop.
No more with kernel 3.4. Tried 3.4.0-1.fc17.x86_64 and 3.4.2-4.fc17.x86_64.
See more info and debug files at
https://bugzilla.redhat.com/show_bug.cgi?id=831136

Using
bbswitch-0.4.2.tar.gz
VirtualGL-2.3.1.x86_64.rpm
bumblebee-3.0.tar.gz
and nouveau kernel module
Thanks in advance for your help.

Hi!
I just tried to use bumblebee/bbswitch on a Lenovo T410 with openSUSE Tumbleweed x64.
Switching is only possible when bbswitch is loaded with the option skip_optimus_dsm=1.

In the case of openSUSE 12.3 the file to edit is /etc/modprobe.d/bbswitch.conf . To load the module on startup, bbswitch has to be added to INITRD_MODULES="bbswitch" in /etc/sysconfig/kernel. After that, its neccessary to update initrd by running the command mkinitrd in the terminal.

It took me a long time to figure this things out so it would be great if two things could be changed in the README:

1. Adding the T410 to the list of computers which require skip_optimus_dsm=1
2. Adding the mentioned way to get bbswitch loaded on startup and working for at least openSUSE. (I am not sure if this way is openSUSE specific, it maybe works for all distros which use systemd now)

Kind Regards
Martin

In reference to /issues/46 and Bumblebee-Project/Bumblebee#358, I would like to add few things.

Thank you to make bbswitch work with 3.8.x and I can confirm that.
There is some notes that need to be aware off.

After upgrading kernel or rebooting different kernel, bbswitch would run fine and able to turn off the nvidia/discrete graphics without any issue.
However, if we are rebooting the computer on the same kernel, bbswitch would not be able to turn the discrete card off.

I have tested this from 3.8.3-201 to the latest one 3.8.3-203.
I noticed that if I reboot on same kernel more than once, 3.8.3-203, the nvidia module will fail to compile, as such bumblebeed will fail to start, causing bbswitch losing ability to switch off the discrete card.

Working around this, reboot to 3.8.3-201, bbswitch will be working fine (cause nvidia module can be compiled ok and bumblebeed started). Turn off. Then reboot again to 3.8.3-203 to allow recompilation of nvidia modules.
But should it be the way?

If any of you need the test output, I will email you separately because it's kind of long.

In addition, once the bbswitch is on (ie. optirun glxspheres), it can't be turned off even the application is already exited, so restarting is the only option.

Thanks.

I have toshiba p870 with nvidia optimus GT 630m running ubuntu 12.10, kernel 3.5.0-21-generic.

I have been trying to make my nvidia card work but no hope so I'm here to seek some help from you!! I have done every step that is available on this site even looked at some troubleshoots and tried them still no hope than I tried the hack method but it screwed up my OS!! I had to reinstall ubuntu again and went to install bumblebee, got the same issues with nvidia not working.
here is some info:

I am trying to use bbswitch on my debian system. I tried following instructions from:

https://github.com/Bumblebee-Project/bbswitch#reporting-bugs

I initially reported the issue as:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=707783

Most of the information can be found at:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=707783#17

I hope this is enough to diagnosticate the issue.

Thanks much

On Linux 3.8, the card is not turned off on a fresh boot. The kernel log reads this on Linux 3.8 (at least v3.8-rc5-218-ga56e160, likely the final 3.8 too)

This happens because the initial device state is unknown (ACPI_STATE_UNKNOWN). A workaround is implemented in:

• 5593d95 Linux 3.8 compatibility hack

However, that was a workaround. A patch for Linux is around in mainline now:

commit b3785492268f9f3cdaa9722facb84b266dcf8bf6
Author: Rafael J. Wysocki <[email protected]>
Date:   Fri Feb 1 23:43:02 2013 +0100

    ACPI / PM: Do not power manage devices in unknown initial states

I need to ping Rafael when 3.9-rc1 is out, then a backport to 3.8 will be made.

Hi everyone,
first of all thanks a lot for your work on that. I have myself maintained a bit of time the special sony-laptop-zseries module [1], a replacement for the in-kernel sony-laptop module, to allow switching between graphics cards.

Most of the added functionality that was in the sony-laptop-zseries modules has now been included in the development branch of sony-laptop [2], but not all, namely the discrete gpu switching. For that I was planning to use bbswitch.

Unfortunately, it seems that the inner workings of my laptop (Sony Z11 old series VGN-Z11) and many others are a bit different. We have a hardware switch Stamina-Speed, which is now also recognized by the sony-laptop module and exported as acppi event.

Using bbswitch I can turn on and off the nvidia card, but the actual graphic output cannot be switched by that, or at least I haven't found out how. The terminal, the kernel, always boots into intel graphics mode.

To give you an idea how it worked before:

• I added acpi_osi="!Windows 2006" to the kernel boot parameter: this is essential (as far as I know)
• then, when turning the speed-stamina switch to speed or stamina resp, on the next reboot already the bios worked with the respective card, thus also linux of course.
• When I keep this parameter and boot up into linux the nvidia card is completely disabled, i.e., does not show up in the lspci, nor can bbswitch find it

I tried unloading the module with the unload_state set to 1, but that didn't help either.

It would be great if one could switch on/off the actual output of the card, too.
