From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

So I have both an igpu and dgpu, which means this should be easy, yeah?

Namely, Ryzen 9 7900 and RTX 4070ti.

But for the love of god I can't get any installation working correctly with this combo OOB.

I've tried Nix. I've tried Arch. I've tried Garuda. I've tried Endeavour. I've tried Pop! OS.

I've also tried Proxmox, Truenas Scale, and Unraid, Smart OS, and others.

But there's always something wrong with display.

Scenario 1. X11 "works", wayland doesn't. Trying to update NVIDIA drivers leads to boot failure.

Scenario 2. Wayland works. Only on igpu. Only via HDMI. Only on one monitor.

Scenario 3. Wayland works on Displayport. Doesn't even recognize second monitor.

Scenario 4. Everything seems to work. Trying to do GPU passthrough fails.

Scenario 5. IGPU is hogging displayport, despite being connected via HDMI, thus preventing the DGPU passthrough on either HDMI or DP.

I don't know what you are trying to do, but you could setup a gpu less Linux base System and then use a virtual machine to actually run your daily os. If this makes things easier

Could you elaborate a bit?

Isn't Proxmox etc. "Gpu less", as they only use tty instead of anything like a WM or DE?

I'd prefer a "master" / hypervisor running a bunch of VM's for different purposes.

Whether they be for gaming, pirating, development, pen testing, home automation, porn, or anything else really.

'Course I'd only be running gpu passthrough into a single VM at a time, can't split a single GPU into 50 passthroughs yet.

[–] Johanno@feddit.de 1 points 1 year ago

Well of course you can use proxmox or tuenas but for "more performance" I would just setup qemu to pass through gpus and input to the vm.

However I don't know if this is worth the hassle.
