https://wiki.archlinux.org/index.php/NV … de_setting

and finaly is someone use it successfully

sorry for my english thanks

Until xorg-server 1.20.6 you will need to patch xorg-server e.g. https://gitlab.freedesktop.org/aplattne … org-server

then you should be able to follow http://download.nvidia.com/XFree86/Linu … fload.html

placing the suggested contents of nvidia.conf in /etc/X11/xorg.conf.d/20-nvidia.conf or rename it to nvidia.conf

thanks your answer
i will wait xorg version 1.20.6 comes. i dont know how i patch the xorg and have risk to broke my system a little
but thank you for help

I tested it with this PKGBUILD for X.Org with the required patches provided by an NVIDIA dev: https://gitlab.freedesktop.org/aplattne … org-server
You may also need to remove the line 12 (PrimaryGPU thing) in:

/usr/share/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf

And it works pretty well! I'm very happy to have such a feature available right in the driver.

does that feature mean that the need for bumblebee, optimus-manager, nvidia-xrun will be obsolete?

Leeo97one · 2019-08-31 13:40:29

Bumblebee will be obsolete for sure but optimus-manager can still be useful. See: https://github.com/Askannz/optimus-manager/issues/114

I wrote a simple script and more or less universal settings for Xorg: Prime

damachine · 2019-09-01 15:04:30

In the nvidia readme it looks simple how to run, but i understand not right how to patch the xorg need some help best a simple step by step. i read about abs pkgbuild etc. but today i am not so smart to understand. i can then look what the command are do. and how risk is a package patching proces, can i rollback simple too like to reinstall the orginal arch package.
thanks

@Feresey https://aur.archlinux.org/packages/prime/

places a config file in etc/X11/xorg.conf.d rather than usr/share/X11/xorg.conf.d
uses license custom but does not include the licnses in a file under /usr/share/licenses/prime
requires xorg-server-git rather than for instance https://gitlab.freedesktop.org/aplattne … org-server.
https://github.com/Feresey/xorg-server-git could use server-1.20-branch instead of master and requiring the ABI breakage.

Would it not be simpler to provide instructions on the wiki?
Edit:
@danmachine the following assumes you have installed base-devel

git clone https://gitlab.freedesktop.org/aplattner/arch-xorg-server.git
cd arch-xorg-server/
makepkg -rs
pacman -Qs xorg-server # to find which packages you need to update avoiding adding new ones
# pacman -U list-of-pkg-files

If you want to revert to the official packages

# pacman -S list-of-pkgs #same list of packages you installed with pacman -U

@loqs, thanks for the advice!

by the points:
1. config file moved to /usr
2. no license no problem
3. removed this dependency
4. This is not my repo, it’s just a fork of another person’s repository, in which I made minimal changes to make it work

damachine · 2019-09-01 17:23:00

@loqs thanks for your help and quick short answer

damachine · 2019-09-01 18:39:13

i have done all successfully but xrandr list not my HDMI port and multihead did not work.

i do all my settings Offloading Graphics Display with RandR undo.
i had only edit my xorg.conf. output of xrandr --listproviders show how it must. glxinfo | grep OpenGL shows the modsetting and with __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME="nvidia" __VK_LAYER_NV_optimus="NVIDIA_only" it shows the nvidia all right.
but xrandr --listmonitors shows only my intern laptop device

i am back to my old setting and i forgot to undo DRM KMS nvidia. should i remove this settings too before i start a new attempt
thanks

From what I could find, it seems it is not possible right now to use monitors that are wired to the Nvidia GPU. You need to run your whole desktop on the Nvidia GPU, you can't use this new offloading feature here.

I have an issue with screen tearing. Do you experience it too on your laptop screen but not on your external monitors?

Just like in this post: https://forum.kde.org/viewtopic.php?t=151762

Also, is it normal that nvidia-settings is more empty than before? https://i.imgur.com/hj60S9y.png

Maybe solutions can be find in the .conf file, that's why I'm asking here

Thanks!

I had to add the following patches to get rid of gl version fails

https://gitlab.freedesktop.org/xorg/xse … /292/diffs
https://gitlab.freedesktop.org/xorg/xse … /304/diffs

Xorg did not recognize the nvidia card though, but with the conf file from prime.git it started working

https://aur.archlinux.org/cgit/aur.git/ … nf?h=prime

Xorg-server 1.20.6 is in the testing repo. Anyone tried?

danielee0707 · 2019-11-26 20:04:08

1.20.6 works for me on XPS 7590 with basic configuration. I also used intel tear-free feature to avoid tearing.
