Just what I was looking for, amazing
Your Single GPU Passthrough video was so awesome and still works flawlessly. I recently setup my own single passthrough setup! Your content is really really good!
The same, took me some time, but after Steve's video I was able to get it done.
epic af, very impressive!
also: "is my audio working?" *without missing a beat* "no" hahaha
Thanks! I also love that the sarcastic answer was faster than all the people who said "yes" 😂
I do love that we all have the same discord friends
The unprompted reactions were priceless 😂
At first, I was very excited to try to replicate your setup on my new PC. I hoped to have various Windows VMs (with Win98, WinXP, Win7, etc.) to have better compatibility with old games.
Then my dream died when I realized that this won't work because there are no GPU drivers for new GPUs that work with old Windows versions...
So, as far as I understand, this setup is only useful for security - important stuff on Linux, gaming on Windows VM.
That's a beautiful setup. I'm definitely putting this in my TODO list...
Thanks! Best of luck to you when you get a chance to try it out!
This is amazing. I've wanted something like this for years. Not sure if it'll be this weekend, but there's definitely a weekend in my future dedicated to this.
Holy COW! Living the dream! Thank you so much for this demo. I did this following your earlier videos (just manual passthrough and restarting my window manager) and while I loved it, it was a bit unstable and I didn't care to keep it. Still dual booting, but I may give this another shot soon! Thanks for all you do Steve!
Hi Steeve. Thanks for the video. Your previous tutorials was what brought me to VFIO. Still, one comment. You actually don't HAVE to have something in your discrete GPU port. You can install an IddDisplayDriver which will emulate a real monitor on your Windows machine and Looking Glass can grab the video from it. I use the one from ge9 but there are other implementations
Great idea! Thanks for the specifics! I'll check that out if I get time, could be good content for another video and I'll be nice to carry one less thing with my laptop 😂
This is perfect!. I really want to try this someday but with two external GPUs so I have the extra ports for a multi monitor setup on linux. Till then I'll stick to old dual booting
Awesome setup. A few months back, I created a Proxmox server and made a Windows VM while passing through my 7900 XT. I stream the content over my network to my Mini PC, which runs Arch. To stream the content, I use Moonlight/Sunshine. Vfio is amazing!
How's the lag on that setup? I did a setup between my gaming laptop and a Steam Deck and had a pretty smooth experience with Sniper Elite 4, but my brother in the replay noted that my frames, while smooth, were definitely delayed which meant I was missing fairly easy shots. Curious if you've noticed the same thing
@kevinpthorne For me it has been smooth sailing. I dont notice any lag or latency issues. It's all dependent on your connection, software, and hardware used. Streaming over a wired LAN connection is the most ideal. For software, I used Moonlight as the client and Sunshine as the server program. This has been the best option for me when streaming over the network as it allows me to mess with the encoding and bitrate options. Having a newer GPU is also beneficial as they have better and improved encoders.
I've been struggling with this on and off for like 5 years now. Would you be willing to post an updated tutorial based on the newer set up ?
You can attach/detach GPU drivers automatically on VM's startup/shutdown via libvirt hooks, just make sure that nothing is occupying your GPU when you start the VM.
like this files.catbox.moe/vekymw.png
Good idea, I guess the reason I haven't done that is because if he scripts do fail I don't want to end up with a semi-launched VM
This makes it a little easier to undo it or try again if things go wrong
Like you said, "just make sure"
This is a really powerful setup and for the most part I got it working. I have however this issue where the system will decide to use the iGPU when booting (obviously, since vfio modules are loaded) and will not switch to the dGPU even when I enable it. The graphic environment will still make use of the iGPU and any new applicaitons I launch will do so as well. I was able to run apps with the dGPU even so by setting the appropriate environment variables, but for some reason that doesn't seem to work for steam, when I set them as launch options.
I'm also using an ASUS ROG laptop with and AMD CPU with integrated graphics and Nvidia GPU, and Fedora 40 KDE on Wayland, just like you used in your guide. I tried a bunch of things but couldn't get this to work exactly like it does for you. It's not a dealbreaker since I don't plan on doing much gaming on linux, but it's been irking me a lot. If you or anyone has any idea what's up, please let me know!
Anyway, thanks a lot for your guides. They've been really really helpful :)
Glad to hear it helpful and nice job getting all those pieces to work!
Did you try the environment variables just like they are in section 2.2.2 in this article
wiki.archlinux.org/title/PRIME
Other than that, I'm not sure if I have other ideas for you (and now I'm nervous something will break when I upgrade to Fedora 40 😂)
Been rocking a dual dedicated gpu setup with Windows 11 + Linux NixOS under Proxmox, monitors side by side and switching input between them using evdev and it has been great and seamless. I experimented heavily with Hyper-V's vGPU technology to see if a single GPU could do desktop graphics on both Windows and Linux but we are not there yet (soon though!!)
Great work Steeve! I have a pretty similar setup, however I prefer to switch inputs and not using Looking Glass. My monitor (Alienware) supports hotkeys for switching inputs, so I am doing pretty much the same.
Thank you for sharing, and hopefully, this will lead more users to use Linux for desktop.
Pretty cool! Physical switch makes a lot of sense. A well designed button in real life is definitely faster than interacting with software
Glad you like it, I agree, one of those days we'll look up and realize it's "the year of the Linux desktop" 😂
Always cool to hear from other early adopters
Freaking Genius!
Thanks! This stuff is too cool not to share
Very interesting.
Thanks!
what
is
this
dark art!!
Big software companies don't control us. We can make our machines as complicated as we like...
I don't know if this is your everyday setup, but I also use gdm on KDE instead of sddm. It's so much cleaner lol
The giveaway will happen... Eventually 😅
Love your videos. Helped me out getting passthrough working on my old m6600. Do you by chance have a steam deck and do you have any pointers to get it working on it?
Keep in mind some games using anti cheat really dislike when you use a VM and will try to block you from doing so. Battleeye and EAC are the ones I’ve seen the most come up with patches that try and block users playing on a VPN but there are ways of masking your VPN.
This is exactly what I was looking for. Please make a tutorial !
Glad to hear it!
This tutorial might have everything you need
ua-cam.com/video/m8xj2Py8KPc/v-deo.html
This series is also more beginner friendly if you'd like to learn about the concepts in addition to the step-by-step ua-cam.com/play/PLG7vUqRxMOG6gsPXohhFht3UJbcCxYgcL.html
I think we need a updated version of single GPU passthrough. I had some small issues on gnome... And didn't work on Kde plasma 6. (All fedora 40)
Also just being sure that the informations are still relevant would be nice!
is there a chance you could do a guide on how to set this up? i'd love to try it
He has all this stuff on his site.
You don’t have to run a script each time you want to bind and unbind the GPU. At least with AMDs cards you’d do dri_prime=‘pci address’ when launching a command and it’ll automatically render on that specific GPU and then unbind to default when not gaming any more. I’m assuming Nvidia’s prime render offloading works the same.
Can you please tell me if you have set up nvidia drm modeset (nvidia_drm.modeset=1) at boot?
I have noticed a major issue when not setting nvidia drm modeset. All the games runs at like half the fps they get with modeset.
Problem is, that I am not able to detach the GPU when nvidia modeset is enabled. Command just hangs (and then one thread is always at 100% usage). I sometimes get this issue even if modeset is not enabled. Command hangs trying to detach gpu (reattach always work).
Also, native Wayland applications do not work (when run on nvidia) if modeset is not enabled, only xwayland apps work.
Also, can you tell me if you are using nvidia open kernel module (nvidia-open) or proprietary (nvidia) package?
Dear Steve, this is really amazing, i followed what you did and some other things from the internet and now i got everything working, could you please provide the aliases you use in a pastebin or a text file and i will change things according to my specs, thank you so much
alright, i have some questions right away... umm.. the hdmi cable is plugged into the motherboard i suppose? then what about multimonitor setups, because thats the deal breaker for me.. will it work?
@@danio3d8 I have 2 ports on my motherboard. One HDMI one Display Port. So I can do two monitors like this
Then if I want to do a third, I can plug it into the GPU and VM display the VM only
Are you using the nouveau drivers when attached to the host os, or proprietary nvidia drivers for your discrete gpu?
The latter
I'm using the proprietary Nvidia driver on the host (while the discrete GPU is connected) and the Intel drivers (when using the iGPU)
Would you be able to do a tutorial on the project WinApps?
This looks really amazing and i'm going to try setting it up on my PC (Running Manjaro with KDE Desktop currently). I just have 1 potential issue though regarding the whole cables situation. My iGPU has both HDMI and Displayport, and my GPU has 3DP and 1 HDMI, however i am running 3 screens, with an aditional TV that i also use from time to time.
TV aside, is there any way to do this reliably while running a 3 screen setup if i don't have the ports available to use from my iGPU...?
Sorry if this doesn't make sense, just lmk :P
@@angusberry3254 that makes sense to me
Would you want to have one or more monitors dedicated to the VM all the time?
Also, you could buy an inexpensive dGPU to run on the host that has more ports than your iGPU
@@BlandManStudios I'm planning to move fully away from Windows, or at least as much as i can, so it would just be 1 monitor. I already have another GPU lying around somewhere actually, although it's a Nvidia one and my main is AMD at the moment... any idea if there would be conflicts with the drivers?
@@angusberry3254 I assume that would be possible, but I haven't tried it myself
Passthrough should be fine, but I don't know about how it would work for gaming on the host
Maybe you can Google around and see if anyone else has done PRIME render offloading with both Nvidia and AMD
Or maybe your best bet is to just try it out and let us know how it goes
@@BlandManStudios I'm going to see how i get on using just the iGPU and dGPU i have installed for now i think. I have an idea that i can use the Thunderbolt / USB-C for 1 display and the other 2 with the motherboard connectors so i might just be able to fudge it that way to be fair :) thanks for the quick responses though, really helps!
I only need windows for some mobile tools that needs some drivers to be installed and to get access to the USB
I want something like usb slot 1 to always passthrough to the VM
is that possible ?
H blandman. great work. I am still on Intel haswell 4790k with z97 motherboard. I have GTX 1080. Will I still be able to do vfio? I think my hardware supports it (vtx and vtd).
would this work on older igpu? like the igpu from 7th gen intel
Yes, but...
Check and make sure your CPU supports VT-d
It is pretty common now-a-days, but a few years ago it was only available with the top-end CPUs. The Intel webpage for your GPU should tell you
Would this work with a MacOS VM? I have some mac only apps and a setup like this would be great for me.
should work with a dGPU supported by macOS, like the Radeon RX 6000 series.
How would this work with dual monitors? Is your previous tutorial still applicable to what you do here? Thanks!
Edit: How does this work with games with an anti-cheat e.g. Valorant or Fortnite? Is this really viable?
It does work with multiple monitors. For me I only use two at a time tho because I only have two ports on motherboard. You'd have to get creative to use the ports on the GPU too
The previous tutorials as still applicable, this just adds some extra stuff on top for usability
I have had luck with some games that use anti-cheat and I listed some of them here: ua-cam.com/users/shortsqWL8_vT6ZjY
But I haven't played fortnight
And I've heard Valorant is almost impossible to work in a VM. They might be the most overzealous about prohibiting VM players. One video I found was called "[nevermind this doesn't work] How to play valorant in a VM" 😂
How can I have the same setup??
By following either of these tutorials

Hi Guys, I tried his guide on laptop and it end up badly. I am using legion 2024 model. Does anybody know a way to achieve GPU-PT in legion laptops. I am using Nobara 39
Have you tried using fedora instead?
Im still using nobara 39 as well I attempted to install gpu passthrough unsuccessfuly.. But I might give a try with fedora 40 kde on my Desktop...
@@jeremy4491 No, I didn't. I just gave up GPU-PT.
How is the input latency in the VFIO? I play a game that is highly reliant on very responsive inputs, and while it runs with Proton, it has a very noticeable input lag penalty.
Latency is not bad (when configured correctly)
Checkout my full testing video: ua-cam.com/video/Ol9O3Jow740/v-deo.html
@@BlandManStudios Thank you! I also found out that you can just pass the USB controller into the VFIO as well
But what about tests?
With actual FPS (AVG/1%Low) differences.
“Reasonable frame rate” seriously?
I like the way you think!
You might like these videos which take a look at FPS, latency, and disk speeds

yawn. could you be more dull.
