I'm using Manjaro Linux on my laptop with switchable graphic cards:

00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)

03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus PRO [Radeon HD 8850M / R9 M265X] (rev ff)

Here's a screenshot of the drivers section of Manjaro Settings Manager: The above shows that bumblebee's drivers are installed, but the daemon fails: [luke@manjaro ~]$ sudo systemctl status bumblebeed ● bumblebeed.service - Bumblebee C Daemon Loaded: loaded (/usr/lib/systemd/system/bumblebeed.service; enabled; vendor preset: disabled) Active: activating (auto-restart) (Result: exit-code) since pią 2015-09-18 16:22:55 CEST; 29s ago Process: 1192 ExecStart=/usr/bin/bumblebeed (code=exited, status=1/FAILURE) Main PID: 1192 (code=exited, status=1/FAILURE) wrz 18 16:22:55 manjaro systemd: bumblebeed.service: Unit entered failed state. wrz 18 16:22:55 manjaro systemd: bumblebeed.service: Failed with result 'exit-code'. During my trial-and-error I also tried to install video-catalyst driver (in window shown above). It ended miserably - after the initial startup the screen was full white. I switched to another TTY and deleted video-catalyst using mhwd. My goal is to be able to play games on Steam. What can you recommend?

I found Nvidia drivers freezes in Cinnamon or their Cinnamon crash or run in fall-back mode. As Bumblebee works better, how can I install Bumblebee in Linux Mint 17?

I have an HP Spectre x360 with two graphics cards (Intel Corporation HD Graphics 620 rev 02 and an NVIDIA Corporation GM108M [GeForce 940MX] rev a2). I installed Debian Testing on it and eventually realized that I needed to use primusrun to let software access the Nvidia graphics card. This worked great for a month or two, and then my Bumblebee setup broke -- possibly during a Debian update or because I removed the wrong package, but I'm not sure. I've since tried uninstalling and reinstalling different Bumblebee/Nvidia/Primus packages to try to solve the problem, but I keep seeing the following segmentation fault in my Xorg.8.log file when trying to run primusrun glxgears:

I was hoping that this would sort itself out when my Nvidia drivers next upgraded, but they just upgraded to 430.50 but remain broken. Any suggestions on what is broken here or what I should look into would be hugely appreciated! Here's my entire Xorg.8.log file:

I have installed the Lightworks video editor on Debian Jessie. For best performance it needs to run on a discrete video card with the proprietary driver. A Nvidia GTX 860M in my case. I have installed Bumblebee to switch between video cards as needed. With optirun or primusrun it is possible to run an application using the Nvidia card. When I use optirun for Lightworks it crashes after startup. When I use primusrun it doesn't and performance is okay. Why is that? What is the difference between the two? This question has been asked before , but remains unanswered. This answer on a different question does allude to a difference, but doesn't explain it.

I have recently switched from open source drivers to nvidia, to bumblebee as instructed by ubuntuforums.org users to better use my two gpu's capabilities. It also so happens that it does not seem to work at all, I keep getting this error regardless of which command I try. Doing ll /etc/bumblebee/xorg.conf.d I can see that this presumed config file is a directory, I am not too knowledgeable about this but I think it's correct provided the .d extension. Full error:

optirun glxgears
[ 9546.928811] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) Unable to locate/open config directory: "/etc/bumblebee/xorg.conf.d"

primusrun glxgears

EDIT: I didn't specify it but yes xorg.conf.d exists and if I try use ll on that directory my result is this:

I've been setting up arch linux for a few days - mostly it's been easy to make progress but I'm having a real problem with multihead support.

I use Arch Linux with the zen kernel. After doing system upgrades my dual GPU setup broke. I use bumblebee to handle dual GPUs. When I run optirun glxgears I get the following output:

[ERROR]Cannot access secondary GPU - error: [XORG] (EE) No devices detected.

[ERROR]Aborting because fallback start is disabled.

When I try opening the Nvidia-settings panel I get the following output:

ERROR: Unable to load info from any available system

My current Nvidia driver version is 495.44 And here is my bumblebee config if that helps: /etc/bumblebee/bumblebee.conf

So, I have a fresh Arch install. I have Bubmlebee, mesa, the intel drivers, bbswitch, etc... The problem is that Nvidia Settings says there is no X configuration file when I launch it. I create one with nvidia-xconfig, but when I start the x server, it says it can not find the display. I have no idea what to do to get it to work. All I need is for it to either be similar to Linux Mint where I can click and switch between integrated and dedicated graphics, or I need to get Nvidia Settings to work so I can turn on v-sync because of all the tearing. Or I might just have to ditch it all and only install one set of drivers.

I've got a weird problem. I installed bumblebee and when I start Xorg with startx it freezes the system completely (cannot switch tty or REISUB). But, when I use bbswitch to turn my dedicated graphics card ON startx **does** work and, seeing the differences in fps when running glxspheres64 and optirun glxspheres64, it looks like bumblebee does work correctly. I thought this should work even when bbswitch is OFF because bumblebee will start the dedicated graphics when necessary? My system: - Model: Asus N551VW - OS: Arch - CPU: Intel i7 6700HQ - Dedicated: Nvidia 960m

But when I installed Manjaro I installed it with NON-FREE drivers and so nvidia, nvidia-libgl and xorg-xrandr are already installed and up-to-date. And my **HDMI port is not working**. I think that's because only the Intel iGPU is present in the X11 conf (HDMI port is part of the Nvidia GPU). While I was trying to find out why, I find that Manjaro does an [Automated Identification and Installation](https://wiki.manjaro.org/index.php/Configure_Graphics_Cards#Automated_Identification_and_Installation) of GPUs during the install. $ sudo mhwd-gpu --check [sudo] password for shark: Using default Default lib32 support: true xorg configuration symlink valid... libGl and libglx symlinks valid... $ sudo mhwd-gpu --status Using default Default lib32 support: true :: status lib32-libGl: '/usr/lib32/mesa/libGL.so.1.2.0' lib32-libGLESv1: '/usr/lib32/mesa/libGLESv1_CM.so.1.1.0' lib32-libGLESv2: '/usr/lib32/mesa/libGLESv2.so.2.0.0' lib32-libEGL: '/usr/lib32/mesa/libEGL.so.1.0.0' libGl: '/usr/lib/mesa/libGL.so.1.2.0' libGLESv1: '/usr/lib/mesa/libGLESv1_CM.so.1.1.0' libGLESv2: '/usr/lib/mesa/libGLESv2.so.2.0.0' libEGL: '/usr/lib/mesa/libEGL.so.1.0.0' libglx: '/usr/lib/xorg/modules/extensions/libglx.xorg' xorg configuration file: '/etc/X11/mhwd.d/intel.conf' The Manjaro Settings Manager (Hardware configuration) is telling me that hybrid bumblebee driver is installed in both case (see screenshot). But my /etc/X11/xorg.conf.d folder is only containing the following symlink 90-mhwd.conf -> /etc/X11/mhwd.d/intel.conf. /etc/X11/mhwd.d/intel.conf content: ## ## Generated by mhwd - Manjaro Hardware Detection ## Section "Device" Identifier "Device0" Driver "intel" BusID "PCI:0:2:0" Option "AccelMethod" "sna" Option "DRI" "true" EndSection Section "DRI" Group "video" Mode 0666 EndSection Section "Extensions" Option "Composite" "Enable" Option "RENDER" "Enable" EndSection Section "InputClass" Identifier "Keyboard Defaults" MatchIsKeyboard "yes" Option "XkbOptions" "terminate:ctrl_alt_bksp" EndSection So what I have to do to make my HDMI port working? And how can I check that my Nvidia GPU is working or not? I don't think I need to install more drivers but I can't figure if I need to use the mhwd tool provided by Manjaro to configure some more settings or if I need to create a new /etc/X11/xorg.conf.d/20-nvidia.conf file or even if I need to replace the intel.conf with a nvidia.conf.

Why in ubuntu (on the top) I've all those entries, while in debian (below) I have a lot fewer? I installed nvidia drivers in ubuntu through gui and in debian through apt install nvidia-driver. In debian I've also same problems and maybe this has to do with nvidia-settings. Indeed installing the drivers for my Nvidia GeForce 950m,the screen sporadically does graphical glitches. These consist of flickering, until I move the mouse abruptly. I also installed bumblebee to try to improve the situation, but nothing changes and not even in nvidia-settings what I need appears. Tried also to use nvidia-xconf, but nothing. 

I am running the Debian 8.0 64bit (Jessie, the stable release) on my HP laptop. I am having hard time in installing the proprietary nVidia driver of my graphic card 01:00.0 VGA compatible controller : NVIDIA Corporation GF108M [GeForce GT 630M] [10de:0de9] (rev ff) I have followed step by step the guides on debian wiki. Bumblebee is required since my graphic card comes with nvidia optimus. So far so good, I think I have all the right packages required on my machine. Now I have to enable bumblebee. It turns out the right command is sudo optirun nvidia-settings -c :8 So a graphic front-end appears, I leave all the defaul checks and I have just to save the configuration file in the /etc/X11 folder as xorg.conf. But at the system restart I get the black screen and x can't start, it says that there are "No screens found". Here it is the log

I am attempting to install three packages through the following command:

install bumblebee-nvidia primus-nvidia nvidia-smi

The bumblebee-nvidia and nvidia-smi work individually however, primus-nvidia can't be found. I think I might be missing a line in my sources.list. Here is my current sources.list:

deb http://deb.debian.org/debian/  buster main non-free contrib
deb-src http://deb.debian.org/debian/  buster main non-free contrib

deb http://security.debian.org/debian-security  buster/updates main contrib non-free
deb-src http://security.debian.org/debian-security  buster/updates main contrib non-free

# buster-updates, previously known as 'volatile'
deb http://deb.debian.org/debian/  buster-updates main contrib non-free
deb-src http://deb.debian.org/debian/  buster-updates main contrib non-free

What do I need to do to install primus-nvidia? Any help is appreciated. For reference, I installed debian through a non-free iso

My laptop, which runs Debian Jessie, has switchable graphics cards (Intel + NVIDIA GT 520M), and for this I have installed Bumblebee & Primus, which depends on the NVIDIA driver in the package manager. Now I need to install CUDA 7.5, and therefore need a more recent driver (even the backports one is too old). However, to install the one bundled with CUDA, I need to remove the one from the package manager, which is not allowed due to the dependency. How can I make the packaged bumblebee work while using a non packaged driver?

My laptop has an unknown display always active in the background. It is called "unknown display" in the system settings on Ubuntu GNOME, and it was the same when I was using Unity. I have once installed Enlightenment before, and I also had to explicitly switch off that display in the settings. This was no problem for me since I only need to switch them off once. Now that I'm using Ubuntu GNOME, gdm seems to behave as if there is another display to the right, beyond the built-in display. I can easily switch it off by using Ctrl+P, but this solution is only temporary. This problem currently causes some rendering faults whenever I move my mouse before logging in, and it causes the background image to be misplaced to the right as the display manager tries to find the center of the two displays. My laptop has a VGA port and an HDMI port. I have once tried connecting my laptop to a TV through HDMI, and the result was that the "Unknown Display" disappeared and was replaced by "HDMI *something*". I would like to permanently disable the "Unknown Display" in gdm. How can I do that? **Update:** xrandr output: Screen 0: minimum 8 x 8, current 1366 x 768, maximum 32767 x 32767 LVDS1 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 309mm x 174mm 1366x768 60.0*+ 1360x768 59.8 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis) LVDS-1-2 disconnected VGA-1-2 connected 1024x768 60.0 800x600 60.3 56.2 848x480 60.0 640x480 59.9 HDMI-1-2 disconnected 1024x768 (0x45) 65.0MHz h: width 1024 start 1048 end 1184 total 1344 skew 0 clock 48.4KHz v: height 768 start 771 end 777 total 806 clock 60.0Hz 800x600 (0x46) 40.0MHz h: width 800 start 840 end 968 total 1056 skew 0 clock 37.9KHz v: height 600 start 601 end 605 total 628 clock 60.3Hz 800x600 (0x47) 36.0MHz h: width 800 start 824 end 896 total 1024 skew 0 clock 35.2KHz v: height 600 start 601 end 603 total 625 clock 56.2Hz Update: Output of lshw -C video WARNING: you should run this program as super-user. *-display description: VGA compatible controller product: GF108M [GeForce 610M] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: vga_controller bus_master cap_list rom configuration: driver=nouveau latency=0 resources: irq:50 memory:a2000000-a2ffffff memory:90000000-9fffffff memory:a0000000-a1ffffff ioport:2000(size=128) memory:a3000000-a307ffff *-display description: VGA compatible controller product: 2nd Generation Core Processor Family Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:48 memory:a3400000-a37fffff memory:80000000-8fffffff ioport:3000(size=64) WARNING: output may be incomplete or inaccurate, you should run this program as super-user.

So first problem i run into is booting from the live image. But after googling a lot i could figure out something and now i am booting like following:

drivers=nonfree

and adding

systemd.mask=mhwd-live.service

to the boot options. After doing this i can boot into the live image. But than if i try to install it it would stuck. So edit the /usr/lib/calamares/modules/mhwdcfg/main.py From:

def run(self):
    for b in self.bus:
        for id in self.identifier['net']:
                self.configure(b, id)
        for id in self.identifier['video']:
                self.configure(b, id)

    return None

To:

def run(self):
    return None

After doing this i am able to install it with follwoing paritions drive 1: ssd /dev/nvme0n1p3 at /boot/efi with fat32 and 250mb /dev/nvme0n1p1 at /swap with linuxswap and 8GiB /dev/nvme0n1p2 at / with ext4 and 111GiB drive 2: hdd /dev/sda1 at /home with ntfs and 931.5GiB i had some errors with ext4... So now it is installed. After the first startup i am doing update:

sudo pacman -Syyu

after this is done i am rebooting and sometimes it stucks but starts after a hard power off. Next i tried to install bumblebee without luck and i had to retry... So i tried added this but i think it is not required in my newest installation i am not using it. /etc/default/grub:

acpi_osi=! acpi_osi='Windows 2009'

than i did:

sudo update-grub

and reboot than i will try so install my dual graphics nvida drivers

sudo mhwd -a pci nonfree 0300

But i am stuck at installing the nvidia bumblebee drivers... Everytime I install them no matter what i am stuck at a complete black screen after reboot and i cant enter with Alt+Ctrl+F1 ... With the free drivers it is running probably but with really bad performance. I tried one more thing which is discribed here: howto-set-up-prime-with-nvidia But after i did everything i am stuck at a black screen again but this time i can access different terminals via CTRL+Alt+F2 ...

I am trying to use the HDMI output on a PC (HP ZBook) with Debian (stretch). I have configured Bumblebee, it works well (glxinfo and optirun glxinfo report the expected information, and I tested complicated GLSL shaders that also work as expected). Now I would like to be able to plug a videoprojector on the HDMI. I have read here that intel-virtual-output can be used to configure it when the HDMI is connected on the NVidia board (using a VIRTUAL output that can be manipulated by xrandr). However, intel-virtual-output says: no VIRTUAL outputs on ":0" When I do xrandr -q, there is no VIRTUAL output listed, I only have: Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 eDP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 345mm x 194mm 1920x1080 60.02*+ 59.93 1680x1050 59.95 59.88 1600x1024 60.17 ... other video modes ... 400x300 60.32 56.34 320x240 60.05 DP-1 disconnected (normal left inverted right x axis y axis) HDMI-1 disconnected (normal left inverted right x axis y axis) DP-2 disconnected (normal left inverted right x axis y axis) HDMI-2 disconnected (normal left inverted right x axis y axis) My installed version of xserver-xorg-video-intel is: xserver-xorg-video-intel_2.99.917+git20160706-1_amd64.deb **Update (Sat. Dec. 09 2016)** I have updated Debian, and now X crashes when second monitor is active when I starting some applications (for instance xemacs). Sat. Dec. 17 2016: Yes, found out ! (updated the answer). **Update (Wed Sep 27 2017)** The method works in 99% of the cases, but last week I tried a beamer that only accepts 50Hz modes, and could not get anything else than 60Hz (so it did not work). Anybody knows how to force 50Hz modes ? **Update (Tue 01 Oct 2019)** Argh! Broken again: After updating X and the NVidia driver, optirun now crashes (/var/log/Xorg.8.log says crash in Xorg, OsLookupColor+0x139). **Update (07 Oct 2019)** Found a temporary fix (updated answer). https://github.com/Bumblebee-Project/Bumblebee/wiki/Multi-monitor-setup

I am using a laptop that has both an Intel and NVidia GPU, with a second monitor plugged on an USB-C adapter and bumblebee enabled. By default, the USB-C adapter connects to the NVidia board, then I am able to use it with bumblebee + intel-virtual-output. Now I noticed that sometimes, randomly, the USB-C adapter connects to the Intel board instead, which I prefer (because it is more direct and display is more fluid than using intel-virtual-output that copies the framebuffer in the background). Since it sometimes happens, it means that it is at least possible. Is there a way of controlling that, that is specifying which graphic board the USB-C adapter talks to ? Note: if I deactivate the discrete GPU in the BIOS, then the USB-C connects to the integrated Intel board. If the discrete GPU is active, then 9 times of out 10 it is connected to the USB-C, and 1 time out of 10 it is the Intel GPU.

I have a Notebook (Xiaomi Mi Notebook Pro) with a Nvidia MX150. So it's utilizing the Nvidia's Optimus technology. As a distribution, I use Fedora 28. ## Bumblebee Therefore I installed Bumblebee to take advantage of this technology. It should be installed correctly since I can start glmark2 via optirun or primusrun. Also running cat /proc/acpi/bbswitch outputs ON. So the Nvidia GPU should indeed be running. ## Docker To install docker, I followed the instructions on https://docs.docker.com/install/linux/docker-ce/fedora/#install-docker-ce Running docker run hello-world outputs what it should, so docker does also work. ## nvidia-docker2 I got nvidia-docker2 installed on Fedora with this commands: curl -s -L https://nvidia.github.io/nvidia-docker/centos7/nvidia-docker.repo | \ sudo tee /etc/yum.repos.d/nvidia-docker.repo sudo dnf install nvidia-docker2 sudo pkill -SIGHUP dockerd ## Installed nvidia packages To check which nvidia packages are installed, I run this command: rpm -qa '*nvidia*' - Output:akmod-nvidia-396.51-1.fc28.x86_64 - nvidia-container-runtime-2.0.0-1.docker18.06.1.x86_64 - nvidia-driver-396.51-1.fc28.x86_64 - kmod-nvidia-4.17.9-200.fc28.x86_64-396.45-1.fc28.x86_64 - kmod-nvidia-4.17.14-202.fc28.x86_64-396.51-1.fc28.x86_64 - nvidia-docker2-2.0.3-1.docker18.06.1.ce.noarch - nvidia-driver-libs-396.51-1.fc28.x86_64 - nvidia-container-runtime-hook-1.4.0-1.x86_64 - libnvidia-container1-1.0.0-0.1.rc.2.x86_64 - kmod-nvidia-4.17.12-200.fc28.x86_64-396.45-1.fc28.x86_64 - libnvidia-container-tools-1.0.0-0.1.rc.2.x86_64 ## Test docker is running with Nvidia GPU Unfortunately, docker doesn't currently run with the Nvidia GPU: optirun docker run --runtime=nvidia --rm nvidia/cuda nvidia-smi I get this error: docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "process_linux.go:402: container init caused \"process_linux.go:385: running prestart hook 1 caused \\\"error running hook: exit status 1, stdout: , stderr: exec command: [/usr/bin/nvidia-container-cli --load-kmods configure --ldconfig=@/sbin/ldconfig --device=all --compute --utility --require=cuda>=9.0 --pid=26115 /var/lib/docker/overlay2/c00aa7855e42deee545cb07531a571538e0d051d38f45e36584a1c850dd47680/merged]\\\\nnvidia-container-cli: initialization error: driver error: failed to process request\\\\n\\\"\"": unknown. ## What am I missing?
