Similar topic https://unix.stackexchange.com/questions/250470/intel-driver-on-nvidia-optimus-laptop-not-recognizing-internal-display

I bought an M16 R2 this September. I ran Fedora, Kali, Void, etc., without a problem until the BIOS update, version 1.10.0. I manually updated to 1.11.0, but to no avail. I suspect NVIDIA Optimus since the GRUB entry seems to try to boot, but the blinking cursor just freezes. I can't switch to different TTYs. I tried nomodeset and blacklist nouveau params for Fedora and Void. Interestingly, Ubuntu also gets stuck but boots just fine after some time. I ran the thorough hardware test, which returned no errors with my hardware. I confirmed ISO files I burned to my thumb drive work. Tried Ventoy, DD, different ports, etc. I reset my BIOS settings. Again, I suspect this is an Optimus issue.

On a fresh install of fedora, both my monitor and laptop screen were working perfectly fine, then after installing nvidia drivers, they installed successfully, but my secondary monitor connected via hdmi didnt work and was not being displayed in display settings. However, my gtx 1050 shows up in nvidia-msi but it says its off. what can I do to fix this

I have successfully installed Nvidia proprietary drivers on Debian 12 but now my system is always using dedicated Nvidia GPU and never the integrated intel one to save battery life. I am pretty sure this is happening because of my xorg config which is here: `Section "Module" Load "modesetting" EndSection Section "Device" Identifier "Nvidia Card" Driver "nvidia" VendorName "NVIDIA Corporation" BusID "1:0:0" Option "AllowEmptyInitialConfiguration" EndSection Section "ServerFlags" Option "IgnoreABI" "1" EndSection ` If i don't use this xorg config Nvidia drivers can't find the Nvidia GPU and i get error (EE) No devices detected and (EE) no screens found(EE). I am using legacy drivers version 390 because my GPU does not support any newer drivers. Does somebody know what i need to change so the drivers can still find my GPU but make the intel iGPU default?

I am trying to make my Debian Linux (KDE Plasma desktop environment, Wayland, stable channel) see my external monitor. My /etc/apt/sources.list :

I am guessing that, as a first step, I should also include the non-free in every single place non-free-firmware is included, and then try to update/upgrade? Or maybe this is not needed? **Update:** Output of ls /sys/kernel/debug/vgaswitcheroo/:

I tried to do a fresh install of a Debian Bookworm on an Asus TUF Gaming A15 RTX 4070 (NVIDIA Optimus), model FA507XI with an integrated AMD Ryzen 9 7940HS. The installation of Debian went without issue. I use Xfce as the DE. SecureBoot and Fastboot are disabled. A first issue with the nouveau driver: black screen after the GRUB menu. However using nomodeset allows me to start the computer and log in. Afterwards I follow the instructions in the Debian wiki , That is: * First install linux-headers-amd64 * Then install nvidia-driver-full and firmware-misc-nonfree * Actually it says nvidia-driver but I need the additional packages from nvidia-driver-full And from there, nothing goes right. * If I use nomodeset, LightDM fails to start * If I use acpi=off, LightDM starts but I have no keyboard nor trackpad * If I use nothing, I have a black screen after the GRUB menu, the same as with the nouveau driver What am I missing? I tried solutions here and there like using the kernel and NVIDIA driver from backports, other GRUB options, in vain. I don't know where to start to do a correct debug as well. I already managed to make it work on the same computer with a Debian Sid install, alas I fail to remember how! --- Messages shown before the black screen freeze:

I have Bumblebee installed but it has a number of problems, not the least of which is being unable to use Vulkan. I tried following the instructions here , in addition to running # apt remove bumblebee*. I rebooted and was able to login with lightdm, but after that the display was black, so I reverted the changes using a different session not running X. Is there something I should do not spelled out in that linked page? It seems like it was written for those trying to set up their NVIDIA-optimus stack, not modify it. I'm running Deepin 15.4.1, which is based on Debian Sid, with slightly different package repositories.

I've been using Arch Linux for the past few years but I've installed it on a new system and am having a problem getting the display to work properly when I start a window manager. * If I run hyprland or startx the screen turns blank and I can't do anything until I reset my computer. * If I try to run i3 or brave-browser I get an error like:

i3: Cannot open display

or

brave: Missing X server or $DISPLAY

I'm using a new computer: ROG zephyrus G16. I have a fresh install of Arch using archinstall. Thanks for anyone with ideas.

There are one Intel integrated graphics and the other Nvidia graphics card in my remote box, where OpenSSH and X11 servers run on Ubuntu Desktop 24.04. The graphics drivers and utils are installed properly as well. $ lshw -c video *-display configuration: driver=nvidia *-display configuration: driver=i915 $ nvidia-smi -L GPU 0 $ prime-select Usage: /usr/bin/prime-select nvidia|intel|on-demand|query $ prime-select query on-demand I think that the term *on-demand* means my card enabled by Nvidia Optimus . However, it is not listed in the supported GPUs mentioned by the Debian Wiki . The list shows there're totally 3 pages, but it remains on page 1 full of old GPUs, no matter I click on next pages using the latest Chrome browser. My first question is whether the poorly maintained web page indicates that the *Optimus* is rather a default feature enabled for all the recent GPUs now, although Nvidia previously promoted it as a selling point for some of old GPUs. My second question is how to adjust the environmental variable *DISPLAY* for X11 server (preferably configured in the *~/.bashrc* file on the remote box) to follow the *on-demand* (ie. dynamically switched) graphics between the integrated and dedicated ones. My use case is that I *ssh* from the local terminal console to the remote box aforementioned, occasionally I need run X11 programs and display graphics on the remote box. Please note that I don't *ssh -X* (ie. nothing to do with X11 forwarding) for the local SSH client runs on a terminal console without X11.

Optimus on Linux is far from perfect however using the native nVidia drivers most issues I had in the past are mainly resolved except one. Whenever I run a full screen application, like Kodi or some Steam games the position is off, either the screen is centered right in the middle of the 2 screens on exactly 1080p or is rendered showing only the left half on any display. I think this is due on how I made the multi monitor setup working using xrandr. When sddm initializes it runs the following command: xrandr --setprovideroutputsource modesetting NVIDIA-0 xrandr --output HDMI-1-1 --mode 1920x1080 --pos 1920x0 --output HDMI-0 --primary --mode 1920x1080 --panning 3840x1080+0+0/0x0+0+0/0/0/-1920/0 It works perfectly however as you might notice the container is 3x1080p as this is due to having 3 screens (all being 1080p), disabling my internal display and using panning I am able to shift the output for 2 monitors right next to each other. It appears I cannot control full screen behavior, noor in KDE or by using put. Playing around in the applications settings I can select which monitor to render it on, but it renders in the center anyways. To clarify: xs on monitor left at 1920/2 ys on monitor left at 1080 xe on monitor right at (1920/2)+1920 ye on monitor right at 1080 To be honest, I've tried many things and I'm at a loss here. I'm not a Linux expert, I've been using it for about 4 years as my only operating system. Since KDE supports Wayland I am willing to give this a try however due to the amount of issues I had with Optimus in the past I am reluctant to try it out because everything is running so smoothly and there is little information about Optimus / Nvidia / Wayland compatibility. Is there anything I might perhaps I've missed before doing anything as radical as changing a stable display manager for a new one? Or perhaps one simplistic command from the terminal for running applications I missed out completely. Any help is appreciated. Additional information: - xorg.conf, xorg.conf.d is empty.

Description of the issue: Horizontal lines, glitches, black or white horizontal bars appear randomly on the screen. It's very, very random. Sometimes it's barely noticeable, sometimes it's like on two videos below. The issue has been there for almost a year. I think it started appearing arount 5.15-5.19 kernel. Glitches don't appear in bios, refind menu, grub or Windows. Everything is perfect there. There also seems to be no problems with nvidia graphics on linux and external displays. Videos: Pop os on generic kernel: https://www.youtube.com/watch?v=k0SSLWwTSKk Pop os on Xanmod edge: https://www.youtube.com/watch?v=BD8Uz7lmtaY Fedora 39 KDE live: https://www.youtube.com/watch?v=qyZj4bB6mq8 I've also tested on Kubuntu, Mint and MX (don't have videos but I haven't been able to find any distro that doesn't have this glitch). Laptop specs: - i7 8750h - 16GB 2666MHz - GTX 1050ti mobile (usually disabled in linux, internal display is connected to intel graphics) - 144Hz 1080p internal display - TongFang GK5CN5Z (sold by XMG, OverPowered, Mechrevo, PCSpecialist, Illegear, BTO, HyperBook, Eluktronics, CyberPowerPC under various names) What I've tried so far: - multiple distros, live and local, reinstalling them - setting various kernel parameters related to intel graphics. max cstate seems to mitigate the problem a bit, just a little while other parameters don't do anything noticeable - installing different kernels and versions, generic, lowlatency, xanmod, liquorix from 6.0 to 6.7.2 (tested about 40 kernels) - checking for hardware damage, replugging internal display cable, it all seems perfect and works on Windows - changing refresh rate - tweaking shitton parameters in linux, I don't remember most of them, I've made at least 100-200 various changes - memtest, no issues - Kernel parameters: intel_idle.max_cstate=1 i915.modeset=1 i915.enable_ips=0 i915.enable_psr=0 i915.enable_dc=0 intel_iommu=igfx_off i915.enable_fbc=0 ahci.mobile_lpm_policy=1

I have a laptop with two GPUs, a AMD integrated one and a headless Nvidia chip. According to [the Nvidia documentation](https://download.nvidia.com/XFree86/Linux-x86_64/515.86.01/README/primerenderoffload.html) , setting the environment variable __NV_PRIME_RENDER_OFFLOAD=1 will cause the Nvidia GPU to appear first to applications, __VK_LAYER_NV_optimus=NVIDIA_only will hide other GPUs, forcing applications to use the Nvidia one, and __VK_LAYER_NV_optimus=non_NVIDIA_only will hide Nvidia GPUs. The former option works fine, but the latter option only adjusts the order, instead of hiding anything:

$ __NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=non_NVIDIA_only vulkaninfo --summary | grep deviceName
        deviceName         = AMD Radeon Graphics (RADV RENOIR)
        deviceName         = NVIDIA GeForce RTX 3050 Ti Laptop GPU
        deviceName         = llvmpipe (LLVM 15.0.6, 256 bits)
$ __NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only vulkaninfo --summary | grep deviceName
        deviceName         = NVIDIA GeForce RTX 3050 Ti Laptop GPU
        deviceName         = AMD Radeon Graphics (RADV RENOIR)
        deviceName         = llvmpipe (LLVM 15.0.6, 256 bits)

Indeed, with the latter option set, many applications still default to the (higher-performance) Nvidia GPU:

$ __NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=non_NVIDIA_only vkcube
Selected GPU 1: NVIDIA GeForce RTX 3050 Ti Laptop GPU, type: DiscreteGpu

This is with Nvidia driver version 515.86.01, the one that currently ships with Debian testing. **How to get applications to only see the integrated GPU**?

I am happy owner of hybrid-graphics system (sarcasm). At my disposal I have a Nvidia GeForce GTX 960m graphics card with Intel integrated graphics card. The lspci names this Intel card as Intel Corporation 4th Gen Core Processor Integrated Graphics Controller. But I believe it would be enough to give the name of the processor ([Intel Core i7-4720HQ](https://ark.intel.com/products/78934/Intel-Core-i7-4720HQ-Processor-6M-Cache-up-to-3_60-GHz)) to identify the Intel graphics card. Yesterday I have installed VMware Workstation 12.5.5 in order to setup Windows 10 as a quest on my Debian 9 (RC3) host system. Unfortunately I have realized that my virtual machine is using Intel card instead of Nvidia card. Let my show output of sudo optirun nvidia-smi:

Virtual machine was started as: optirun vmware I know that some of you might say "*you can **not** use Nvidia card on your guest virtual machine*". But my question is **not** about GPU passthrough... If I had to PCI passtrough my Nvidia card to the virtual machine, I would use qemu/kvm - not VMware Workstation. All I want to do or see is the following: 1. Run optirun vmware 2. See VMware VM (or vmx) listed as a process running on the Nvidia GPU (nvidia-smi would be the indicator). (Sorry, by VMware VM or vmx I mean my guest virtual machine) How can I force this behavior? I admit that I tried only to run workstation through optirun but I don't know what else to do.

Also, it prompts me to select if I want to switch to the external screen, unify outputs, extend display to the left or extend the display to the right when I plug in the HDMI cable or unplug it. Clicking either of those options in the prompt does nothing. For context, I am using linux-zen-6.0.11.zen1-1 and nvidia-dkms, and using KDE Plasma as my graphical environment.

I attached a new 2560x1440 display (Dell P2416D) with HDMI to my dual-booting laptop (Asus N56VJ) that has NVIDIA's dual-GPU technology. In Windows 8.1 I got the display to run with its native resolution and 60 Hz refresh rate by creating a custom resolution in NVIDIA settings. The display menu also shows that it is running 2560x1440 @ 60 Hz, so no downscaling is involved. However, in Ubuntu 15.10 I have had no luck enabling the native resolution. The display settings widget is only offering picture sizes up to 2048x1152, and running Xrandr fails in the following way: fabio@fabio-N56VJ:~$ xrandr --newmode 2560x1440 311.825 2560 2744 3024 3488 1440 1441 1444 1490 +hsync +vsync fabio@fabio-N56VJ:~$ xrandr --addmode HDMI-0 2560x1440 X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 18 (RRAddOutputMode) Serial number of failed request: 36 Current serial number in output stream: 37 I have tried modelines generated by the gtf tool, and ones based on Windows settings exported by PowerStrip. I am running the latest NVIDIA binary drivers available in Ubuntu, meaning nvidia-352. My HDMI cable supports specification version 1.4, too, although that should not be the problem since display is running fine on Windows. Is there a way I could force X.org or Xrandr to force set the mode, or another way to get to use the display without scaling?

Whenever I close the lid of my laptop for more than 5 seconds the following happens: * A lot of text and icons / images disappear completely or get distorted. * This includes app bar, menu items in top bar. * This does not include content inside applications. If I launch a new application, it's icon is displayed like normal. I imagine this is some kind of memory issue when hibernating. It is if the OS is attempting to pull up whatever was stashed in memory and it is not the expected data. System information: **OS**: Pop!_OS 22.04 LTS x86_64 **Host**: 81LK IdeaPad L340-15IRH Gaming **Kernel**: 5.19.0-76051900-generic I have tried: * Setting up a swapfile. * Looking in settings for hibernation settings.

I've installed Void Linux on Xiaomi Redmibook Pro 15 2022. I'm experiencing the strange graphic issue: In X11 UI works slow. It's even hard to manipulate mouse cursor: it freezes and gets stuck. But if I start video on youtube or run glxgears everything starts to work normal. Also in TTY if I hold any button screen is not been updated at real time. Letters appear after I release the button. And if I start X, wallpapers and bar appear only after I move cursor or press any button. I assume that the problem is with Intel driver. Because on kernels 5.13 and 5.15 lswh marks iGPU "UNCLAIMED" and I can't start X, but TTY works properly and letters appears immediately. Prerequisites: CPU: i7-12650 dGPU: Nvidia RTX2050 Kernel: 5.18.9 with nvidia-drm.modeset=1 mode setting WM: Qtile(same thing with i3) Display: 3200x2000p, 90Hz No DM. Also I did not configure DPI yet, UI is very small, but I don`t think it could be a problem. My ~/.xinitrc

xrandr --setprovideroutputsource modesetting NVIDIA-0  
xrandr --auto

I've installed Ubuntu alongside with Void and everything works out of the box with kernel 5.15. If needed I can provide any additional information(maybe some outputs from Ubuntu vs Void) I tried to find any differences in dmesg and lshw outputs between Ubuntu and Void. I did not find something significant, except: 1)Void: setup_percpu: NR_CPUS:256 nr_cpumask_bits:256 nr_cpu_ids:16 nr_node_ids:1U buntu: setup_percpu: NR_CPUS:8192 nr_cpumask_bits:16 nr_cpu_ids:16 nr_node_ids:1 2) Void dmesg does not contain these lines:

[    0.140758] DMA: preallocated 2048 KiB GFP_KERNEL pool for atomic allocations
[    0.140875] DMA: preallocated 2048 KiB GFP_KERNEL|GFP_DMA pool for atomic allocations 
[    0.140999] DMA: preallocated 2048 KiB GFP_KERNEL|GFP_DMA32 pool for atomic allocations

3)In Ubuntu lshw list devices models, but void lists only vendors. I would really appreciate any suggestion! There are the files containing outputs of corresponding programs/OS dmesg ubuntu dmesg void lshw-ubuntu lshw-void

I have a laptop with i7-12700H and RTX 2050, with only a single VGA controller connected with iGPU. lspci | grep -iE "vga|3d" shows:

00:02.0 VGA compatible controller: Intel Corporation Alder Lake-P Integrated Graphics Controller (rev 0c)
01:00.0 3D controller: NVIDIA Corporation GA107M [GeForce RTX 2050] (rev a1)

I have an HDMI port on the side of my laptop, which works well while using windows and booting Linux (for example, under grub). However, once i915 driver is loaded, the external screen become black and complains "no signal". This is my kernel log: https://fars.ee/gQTL Could anyone figure out where is the problem?

I bought a laptop that has integrated Intel graphics and a discrete nVidia GPU in the "Optimus"-type setup. The integrated graphics are typically fine, but the laptop's HDMI and DisplayPort ports are physically wired only to the nVidia chip. After some experimentation in which I did get PRIME working on a per-application basis outputting to the built-in display, it seems that [libglvnd](https://github.com/NVIDIA/libglvnd) is The Future of multi-GPU rendering, so I updated my Gentoo system to Xorg 1.20.8, Linux 5.7.8, and nvidia-drivers 440.82-r3 with libglvnd support enabled. I have no explicit xorg.conf and am allowing the automatic detection and configuration to run. xrandr --listproviders shows that both of the cards are being detected and registered, but I don't see any "sinks" or other items that I can select using xrandr (1.5.1):

Providers: number : 2
Provider 0: id: 0x45 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 2 associated providers: 0 name:Intel
Provider 1: id: 0x220 cap: 0x0 crtcs: 0 outputs: 0 associated providers: 0 name:NVIDIA-G0

and xrandr -q only shows the Intel outputs:

Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
eDP1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 340mm x 190mm
   1920x1080    120.11*+  48.08  
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

The Xorg log (full startup log below) shows that the nVidia driver is reporting hotplug events on the graphics ports when I plug and unplug the cables.

As far as I understand, it looks like the core libglvnd setup is working properly, but I can't determine how to switch over to the nVidia GPU so I can use my output ports. When experimenting with the earlier PRIME models, using environment variables such as DRI_PRIME or __GL* was the thing to do, but I used strings on the libglvnd binaries and didn't find anything promising, and the libglvnd package doesn't come with any utilities similar to optirun. **Once my multi-GPU setup is detected and correctly reporting hotplug events, how do I activate the dGPU with libglvnd so I can use my external monitor ports?** Xorg startup with input devices removed to fit in the limit:
