You can disable screen blanking when using intel-virtual-output with xset by setting the DISPLAY environment variable appropriately (see DPMS for more info): If you have multiple NVIDIA graphics cards (eg. after resolving my latest issues with intel-virtual-output not finding my external virtual outputs I now noticed that the 'speed' is very slow. In some instances, running optirun will return: In this case, you will need to move the file /etc/X11/xorg.conf.d/20-intel.conf to somewhere else, restart the bumblebeed daemon and it should work. Successfully merging a pull request may close this issue. In both cases the external monitor has got a proper signal from my laptop. I'm still a Gentoo n00b. In some instances, using primusrun instead of optirun will result in a segfault. Using intel-virtual-output works really well with little tweaking necessary. The detected displays will be manageable via any desktop display manager such as xrandr or KDE Display. $ intel-virtual-output $ xrandr --output VIRTUAL4 --mode VIRTUAL4.738-2560x1440 --right-of eDP1 --primary My bumblebee configuration is attached. intel-virtual-output is a utility for Intel integrated graphics chipsets on hybrid systems. In the “device” section, change option UseEDID to true. 1. Steps to reproduce: Upgrade to extra/xf86-video-intel … Window appears. You need to probably change the BusID for both the Intel and the NVIDIA card. As a workaround, add pcie_port_pm=off to your Kernel parameters. If the discrete card is activated by some program (lets say mpv with gpu backend) and stays on. The tool connects local VirtualHeads to a remote output, allowing the primary display to extend onto the remote outputs. In the Synplify software versions earlier than 2009.12, synthesis inserts TRI1 I/O primitives for unconnected output ports. Then I've decided to try the live disks of Kubuntu 16.04.3 and Kubuntu 17.10. On some laptops, the NVIDIA card may not correctly initialize during boot if the card was powered off when the system was last shutdown. When run in a terminal, intel-virtual-output will daemonize itself unless the -f switch is used. A virtual screen is an external screen. I tried it with sudo as well. LEAP 15.1 Bumblebee is not connecting to hdmi external monitor using intel-virtual-output. Top. Set the "AutoAddDevices" option to "true" in /etc/bumblebee/xorg.conf.nvidia (see here): This could be worked around by appending following lines in /etc/bumblebee/xorg.conf.nvidia (see here): You probably want to start a 32-bit application with bumblebee on a 64-bit system. See NVIDIA Optimus#Lockup issue (lspci hangs) for an issue that affects new laptops with a GTX 965M (or alike). To start viewing messages, select the forum that you want to visit from the selection below. The following table gives a raw overview of a Lenovo ThinkPad T480 in an eGPU setup with NVIDIA GTX 1060 6GB and unigine-heavenAUR benchmark (1920x1080, max settings, 8x AA): Bumblebee renders frames for your Optimus NVIDIA card in an invisible X Server with VirtualGL and transports them back to your visible X Server. I also have this issue. You may have to register before you can post: click the register link above to proceed. Also it seems like CPU consumption is not really affected. Edit 2017-07-14: Intel + Nouveau combination is deprecated. Hi, I'm having the same issue, just wanted to point out that I tried Linux Mint and it's working properly there (they use kernel 4.10 + 380 NVIDIA drivers). Test primusrun with VSYNC disabled: If you are satisfied with the above setting, create an alias (e.g. When you stop the daemon manually, you might want to keep the card powered off while still powering it on on shutdown. As a result, the GPU may fail to power on, fail to power off or worse. No announcement yet. intel-virtual-output -f # To let the process attached to the terminal intel-virtual-output # To detach the process List the available screens (main screen + virtual). Comment 2 c 2015-04-28 09:19:41 UTC (In reply to Chris Wilson from comment #1 ) > Can you double check you are using a build from git? Note that this setting does not influence power state while the daemon is running, so if all optirun or primusrun programs have exited, the GPU will still be powered off. Simply put, this can help NVIDIA Optimus/Bumblebee users on Linux. One example configuration is below for two identical screens with 1080p resolution and using the HDMI out. extra/xf86-video-intel 2.99.912-1 * config and/or log files etc. If you do not want to use intel-virtual-output, another option is to configure Bumblebee to leave the discrete GPU on and directly configure X to use both the screens, as it will be able to detect them. When the laptop is running on battery supply, the dedicated GPU is turned off to save power and prolong the battery life. I followed the instructions, except the installation of newer drivers since the tutorial is rather old and these versions are already in the repositories. Switching off LVDS1 brings back the delay. If bbswitch (for linux) or bbswitch-dkms (for linux-lts or custom kernels) is installed, it will be detected automatically when the Bumblebee daemon starts. Then, you can log in the integrated-graphics powered one. i-v-o's bandwidth is severely limited due to Nvidia drivers not supporting DRI3/Present. Switch to Virtual Console (Atl + Ctrl + F1 .. F6) Stop the xserver sudo service lightdm stop (for init) or sudo systemctl stop lightdm.service (for systemctl) Remove any existing installs of nvidia, nouveau etc. Users are reporting that in some cases, even though Bumblebee was installed correctly, running. If you mistakenly had the display connected to the discrete graphics card and intel graphics was disabled, you probably installed Bumblebee after first trying to run Nvidia alone. https://bugs.freedesktop.org/show_bug.cgi?id=96820#c3. Forum: Hardware. Do you have any more ideas? Log out from the desktop session and open up a virtual tty console, just press this key ... Furmark was able to run the test at 16 to 20 FPS while the Intel HD 3000 GPU stuck at 8-9 FPS. Comment by Michał Kopeć (mkopec) - Thursday, 23 March 2017, 17:57 GMT intel-virtual-output only works with Intel DDX. This is caused by an issue in code auto-detecting faster upload method, see FS#58933. This is sometimes called PCI passthrough. intel-virtual-output to external DP screen is very slow. Subscribe to RSS Feed; Mark Topic as New ; Mark Topic as Read; Float this Topic for Current User; Bookmark; Subscribe; Mute; Printer Friendly Page; Altera_Forum. Set load_state and unload_state module options according to your needs (see bbswitch documentation). Also, what really bothers me is that I've been successfully using this setup in the last year. See the "For 32-bit..." section in #Installation. This page was last edited on 19 December 2020, at 21:42. Intel Community; FPGAs and Programmable Solutions; Programmable Devices; The virtual clock about input or output in timing constrain; Options. To achieve the latter, add the following systemd service (if using bbswitch): Then enable the nvidia-enable.service unit. By clicking “Sign up for GitHub”, you agree to our terms of service and It is not supported by Bumblebee anymore. The present releases only support rendering on-demand, automatically starting a program with the discrete video card based on workload is not implemented. Description In the Synplify software versions earlier than 2009.12, synthesis inserts TRI1 I/O primitives for unconnected output ports. For 32-bit applications support on 64-bit machines, install lib32-primus (multilib must be enabled). Setting primus as the bridge for optirun provides more flexibility. If the above command did not help, try finding your NVIDIA card's bus ID: For example, above command showed 01:00.0 so we use following commands with this bus ID: and if you try to load the nvidia module you get: This could be because the nvidia driver is out of sync with the Linux kernel, for example if you installed the latest nvidia driver and have not updated the kernel in a while. p.s. If no target displays are parsed on the commandline, intel-virtual-output will attempt to connect to any local display. The workaround is skipping auto-detection by manually setting PRIMUS_UPLOAD environment variable to either 1 or 2, depending on which one is faster on your setup. Run optirun true to start the Bumblebee X server if you want to start display output on your local screen; Run intel-virtual-output to plug the NVIDIA hardware outputs as virtual outputs on the current X screen; At this point the plugged external monitors will become available in XRandR, as virtual devices, e.g. Nvidia supports reverse prime, but only as a source provider. To manually turn the card on or off using bbswitch, write into /proc/acpi/bbswitch: The default behavior of bbswitch is to leave the card power state unchanged. Run optirun true to start the Bumblebee X server if you want to start display output on your local screen; Run intel-virtual-output to plug the NVIDIA hardware outputs as virtual outputs on the current X screen; At this point the plugged external monitors will become available in XRandR, as virtual devices, e.g. You signed in with another tab or window. If Bumblebee starts/works in a random manner, check that you have set your Network configuration#Local network hostname resolution (details here). xf86-video-intel provides the intel-virtual-output tool, which … If you have a newer laptop (BIOS date 2015 or newer), then Linux 4.8 might break bbswitch (bbswitch issue 140) since bbswitch does not support the newer, recommended power management method. Unbootable system, crashes during boot, a system that boots into unresponsive black screen with a white text cursor blinking in the top left corner, Cnchi and LiveDE freezes are only few of Nouveau effects. You might need to define the NVIDIA card somewhere (e.g. As commented here, nouveau driver has some issues with some cards and bumblebee. Here is a performance table tested with ASUS N550JV laptop and benchmark app unigine-heavenAUR: To use a standard compression for all applications, set the VGLTransport to compress-method in /etc/bumblebee/bumblebee.conf: You can also play with the way VirtualGL reads back the pixels from your graphic card. However, bbswitch is for Optimus laptops only and will not work on desktop computers. See [6] and [7] for more information. A virtual screen is an external screen. This occurs even when the "Disable I/O Insertion" option is selected from the Device tab of the Implementation Options page in When I try to connect the second monitor, I get the following response: intel-virtual-output -f No VIRTUAL outputs on ":1". Intel + Nouveau support can be dropped from Bumblebee at any time. The Intel card has in general less tearing, so use it for video playback. Bumblebee is a software implementation comprising two parts: Render programs off-screen on the dedicated video card and display it on the screen using the integrated video card. Video tearing is a somewhat common problem on Bumblebee. xorg xrandr. My whole desktop is non-responsive anymore. This is known to be necessary on Lenovo's Legion Y720. Compressed methods will mostly load the CPU. Intel Linux; If this is your first visit, be sure to check out the FAQ by clicking the link above. I don't need to use any sort of virtual output on my laptop in order to get the nvidia driver to display to the laptop screen (which is wired to intel). , then do it.In my case i had to rerun the above command as : For example, start Windows applications with Optimus: For another example, open NVIDIA Settings panel with Optimus: For a list of all available options, see optirun(1). Sign up for a free GitHub account to open an issue and contact its maintainers and the community. sudo apt-get install bumblebee bumblebee-nvidia primus linux-headers-generic Note : Keep an eye on the output of the above command. Bumblebee supports Intel + Nvidia combination only. Addressed an issue where the AHS Download application from the System Utilities Embedded Applications or UEFI Shell may fail to work properly with iLO firmware 1.30 or later. (Maybe use portage for intel-virtual-output program?) See the Bumblebee wiki page for more information. Uninstall that driver in the similar way: 2. Which distribution are you running? If anybody spots room for improvement, please mention it. Fixing xorg.conf.nvidia. Nouveau video driver causes many troubles on NVIDIA Optimus cards. I guess you probably have a misunderstanding of how slow it actually is. Use export DISPLAY=:0 to revert back to standard operation. It will then perform all the trickery of virtualizing and cloning so that the newly attached screen can be used via conventional screen management methods, such as cloning/extending with xrandr. Started by jsberrios, 11-Feb-2020 08:32. Running ‘intel-virtual-output’ (from the intel-gpu-tools rpm) without any extra parameters will daemonize itself and detect attached displays in the background. The second will be started through optirun on the NVIDIA card, to show on the external display. May 6, 2020, 6:01pm #6. A quick check can be done with vulkaninfo from vulkan-tools. Interestingly, when I first connected my second monitor I had the same issue. Render programs off-screen on the dedicated video card and display it on the screen using the integrated video card. We are going to use Python with the Request framework and BeautifulSoup for further Scraping. If integrated graphics had previously been disabled and discrete graphics drivers installed, be sure to remove /etc/X11/xorg.conf or the conf file in /etc/X11/xorg.conf.d related to the discrete graphics card. Simply put, this can help NVIDIA Optimus/Bumblebee users on Linux. Nouveau video driver causes many troubles on NVIDIA Optimus cards. To activate external display I run: $ optirun true $ intel-virtual-output $ xrandr --output VIRTUAL4 --mode VIRTUAL4.738-2560x1440 --right-of eDP1 --primary My bumblebee configuration is attached. there are two ways to fix this issue - reboot your system or execute the following command: And try to test if primusrun or optirun works. intel-virtual-output gives me: ~ $ intel-virtual-output No VIRTUAL outputs on ":1". Set them to use the Intel card, but Bumblebee can still use the NVIDIA card. When you use intel virtual output and compositing for some reason all pixels are redrawn at each frame (as opposed to only the ones that are changed) which causes Xorg to use 70/80% CPU at pretty much all times. Replies: 1; Views: 502; Last Post By: Last Post: 20-May-2020 14:35 by RP . 关于Bumblebee，见这里：Bumblebee - ArchWiki （中文版：Bumblebee (简体中文) ，但是中文版比较旧了，特别是关于HDMI输出那一段，还是建议参考上面英文版的为主） 对于Intel核显＆NVIDIA独显的笔记本（甚至台式机），配置好bumblebee后，可以使用optirun来在独立显卡上运行程序，然后在核心显卡上 … If the laptop screen is stretched and the cursor is misplaced while the external monitor shows only the cursor, try killing any running compositing managers. If this change is not made the daemon may default to using the internal NVIDIA card. Do other drivers support virtual outputs, too? privacy statement. In this case, be sure to remove the /etc/X11/xorg.conf or .../20-nvidia... configuration files. If you do need to change some features for the Intel module, a workaround is to merge /etc/X11/xorg.conf.d/20-intel.conf to /etc/X11/xorg.conf. See Bumblebee#Output wired to the NVIDIA chip for details. However use the installation procedure detailed above. Now I can't get the second display to work. Now, after some updates it is in this new state. An input/output memory management unit (IOMMU) enables guest virtual machines to directly use peripheral devices, such as Ethernet, accelerated graphics cards, and hard-drive controllers, through DMA and interrupt remapping. To disable this set environment variable __EGL_VENDOR_LIBRARY_FILENAMES However, my laptop screen got turned off. Add rcutree.rcu_idle_gp_delay=1 to the kernel parameters of the bootloader configuration (see also the original BBS post for a configuration example). It looks at the available screens on the remote display and presents them on the Intel X server as VIRTUAL1, VIRTUAL2, etc. I used to have my laptop connect to an external monitor using the "intel-virtual-output." Bumblebee supports Intel + Nvidia combination only. Make sure nvidia-persistenced.service is disabled and not currently active. alias primusrun="vblank_mode=0 primusrun"). Nvidia + Bumblebee (Optimus) on Ubuntu. Now I can't get the second display to work. The only way to make Optimus work dynamically on non-Windows OS is to use Bumblebee. 11 Nov 2016. Bumblebee supports Intel + Nvidia combination only. $ intel-virtual-output -f. Note: -f prevents it from becoming a daemon (thus easier to stop) Note: Starting with nvidia-360 the nvidia-modeset module will prevent bumblebee from unloading properly and has to be removed first. The Intel X.Org driver has gained virtual output support to extend the local desktop with remote outputs. You might encounter an issue when after resume from sleep, primusrun or optirun command does not work anymore. The intel-virtual-output command provides a way for an X server on the Intel card to duplicate screens to another X server. on shutdown) due to the (default) setting TurnCardOffAtExit=false in /etc/bumblebee/bumblebee.conf. intel-virtual-output [
