Does anyone know any good guides for installing this on a X1 Carbon Gen 5? I've been wanting to try this out on my X1, but there isn't really any nuance when it comes to guides for it. Just a list of problems and what does and doesn't work.

I've been running qubes 4 on an X1 Gen 5 carbon. I can put together a guide tomorrow. Message me again just in case I forget and do it again on Monday just in case again.

Well I can't message you on here, but you should definitely reply to this comment and post it when you do it!

Would be happy to use Qubes if I could also get a certified laptop to run it on. Even after months their hardware requirements page still says "Unfortunately, there are currently no certified laptops for Qubes R3.x or R4.x. This page will be updated once certified laptops are available." Anyone have any insider ETA or recommendations? Prefer a practical/reliable laptop over some expensive racehorse. What laptop does…

Qubes OS' virtualization technology is awesome - love the peace of mind it gives!

You cannot. If you have VT-X and VT-d, you might be able to create a Windows HVM and pass through your GPU, but Qubes official support for this is close to nil, and success is very dependant on your specific setup. Some cards plainly won't work, some won't work with given CPU/Mobo combos, etc. I made my GTX980 work on Arch, and tried on Qubes, but Qubes itself was too unstable for my daily driver, so I never got it c…

That's too bad. Oh well.

Another approach is to run a minimal Arch on metal, and everything else in VMs. If your motherboard is compatible with GPU passthrough, the dGPU can now be passed among the VMs without hardware reboot. The GPU performance loss is minor, but I saw added latency variance when doing VR. I've seen several HN comments from folks happy with this approach.

How is the GPU pass-through support in this release? I'd love to use Qubes but I sometimes want to use my GPU for games or other OpenGL stuff. Is this already working good or is it still a bit bumpy?

Afaik they are not working on that at all.

Please keep in mind when using Qube OS is that it does NOT protect you if your hardware is compromised. The NSA and other clandestine agencies have an easy backdoor to your computer even when running this.

No they don’t.

Sure they do, just not really Qubes OS specific ones though.

I've been interested in Qubes OS for a long while, ever since I first heard about it years ago. A little while ago I upgraded my desktop and I now have an 8-core Ryzen 7 1700 (that's 16 threads!) and 32 GB of RAM. I installed Kubuntu on it after the first few results on Google suggested Ubuntu would let me install and use the proprietary drivers for the graphics card that I bought; a GeForce 1060 GTX with 6GB VRAM. U…

I had the bug with the disk encryption screen on my xp13 as well. Removing the splash screen and just having a terminal helped it boot normaly. Something along the lines of this: https://askubuntu.com/questions/854388/ubuntu-16-04-cannot-e...

Is this secure against Spectre/Meltdown?

With 8Gb of RAM I have been happily using Qubes 4 in my work workstation since rc2. I suggest to use the mirage firewall image [1] to save aound a Gb of RAM The fedora 27 images can easily reach 5Gb of use under heavy load, but in gneneral I have pretty good performances and I usually have a couple of throwaway VMs and the main work VM running and dealing with web, co pilations of various sort and editing.

Why use Fedora for images and not something leaner, like Arch or Alpine Linux? (just examples, there are others too)

You can use the minimal template https://www.qubes-os.org/doc/templates/fedora-minimal/, also available for debian.
