In multi-x-screen ZaphodHeads configurations, there isn't a one-to-one mapping of kernel provided drmmode crtc index to the index of the corresponding xf86Crtc inside the xf86CrtcConfig crtc array anymore, ie. for kernel provided drmmode->mode_res->crtcs[i], the i'th crtc won't correspond to the xf86Crtc in t...

I don't understand this patch (what are all these masks? how are they used?), and don't want to invest the time required to do so. However Mario is probably the sole serious user of ZaphodHeads, and if it fixes issues for him, probably fixes issues for others who try and give up with ZaphodHeads. Any objections if I just push this out? On Sat, Jun 27, 2015 at 8:33 PM, Mario Kleiner <mario.kleiner.de at gmail.com> wrote: > In multi-x-screen ZaphodHeads configurations, there isn&...

[Posting again. The mailing list doesn't like HTML links.] Hello, As I reported in this(*) bug, the Nouveau ZaphodHeads option (separate X-displays for the two heads of a single GPU) stopped working on my GeForce 7600 GT (NV4B/G73) when I upgraded from Fedora 23 to 25. I'm really keen on getting it back, because it's been painful losing the independent sets of virtual desktops, plus other annoyances I'm...

...on >= maxwell. modesetting and nouveau are not on par feature-wise atm. E.g., modesetting as of the next xorg 1.18 server only provides pageflipping via dri3/present and without pageflipping it is game over for many of my use cases on nouveau-kms. Also modesetting currently completely lacks ZaphodHeads support. Without ZaphodHeads i can't have a page-flipped fullscreen window on one subset of outputs and a regular desktop on another subset, something that is needed for neuroscience/medical/vr applications. So i'd rather like to preserve the choice of glamor. What makes glamor + dri2...

Admittedly I've never tried this, but I can't think of anything that would prevent you from doing this using the ZaphodHeads/Xinerama approach. Take a look at http://nouveau.freedesktop.org/wiki/MultiMonitorDesktop/ -- pay special attention to the highly-unintuitive Screen setting inside of the Device section -- it appears to be the index of the crtc to be used on that device, not the overall screen number (so it just r...

Here are a few patches adding some missing functions in NvPlatformProbe, which iirc is being used as of xserver 1.13 First patch adds a nouveau_kernel_mode_enabled helper, similar to xf86-video-radeon Second and third use the function in Nv{Pci,Platform}Probe And last one ensures we can still use ZaphodHead and relative head positioning via xorg.conf The coding style may be a bit off, despite my best attempts Please review and comment [PATCH 1/4] nouveau: add nouveau_kernel_mode_enabled() [PATCH 2/4] nouveau: Use helper function [PATCH 3/4] nouveau: Check for kms in NvPlatformProbe [PATCH 4/...

Dear nouveau developers and users! After many years of dealing with the blob in my kernel, I decided it was time to move to an open source solution. With one of my machines, equipped with 9500GT it went almost flawlessly. I had to patch kernel to get GLXVBlank option working (only because I used the latest and greatest 3.7-rc6), but that is all, and I'm very happy with the result. Nouveau on
