Hybrid Graphics

demm

I'd like to call upon anyone having access to a system with a hybrid nvidia setup. So far KaOS has not added anything to get ready for hybrid graphics cards, simply bc no-one mentioned having such a setup, so it was impossible to test.

A new way of building proprietary nvidia is tested locally, it installs alongside libgl, seems to work well enough on regular nvidia system, just high end webGL is slower.

If anyone can test, then I'll make a tutorial available, and upload the needed packages to . This trial means no need for Bumblebee.

demm: I`d like to test and want to know the tutorial available for proprietary nvidia to my hybrid graphics

demm

THIS TUTORIAL IS NO LONGER VALID, no answers whether it works for hybrids, regressions for other cards.

Tutorial will be here, until it is proven to work and tested well (will move to the tutorial section then).

There are a few options to try and work with hybrid cards.

Completely disable one card, enter the BIOS and on the "Configuration" tab, change "Graphic Device" from "Switchable Graphic" to "UMA Graphic" (or similar entry depending on your MotherBoard), this usually only leaves the intel card active.

Only use the intel card, then simply install xf86-video-intel, do not install any nvidia or ATI

Install xf86-video-nouveau or xf86-video-ati alongside xf86-video-intel. After rebooting, X should automatically detect the drivers and work.

Use the proprietary NVIDIA driver

Using the last option takes quite a few steps.

You'll need to have the repo enabled and running linux-next (needs 3.11 to work):

kdesu kate /etc/pacman.conf

Add above , and add the same Server = line right under it

sudo pacman -Syy

mirror-check

sudo pacman -Syu

sudo pacman S linux-next linux-next-headers nvidia-next

If you have regular nvidia installed, remove it for now, it is not build for this beta version:

sudo pacman -R nvidia

Make sure to update grub, so you can choose either kernel on next reboot

sudo grub-mkconfig -o /boot/grub/grub.cfg

And at this stage, libgl needs to be installed too, check with:

pacman -Q libgl

install when not present.

To use the proprietary NVIDIA drivers, install xf86-video-modesetting and nvidia-next (xorg-xrandr is also needed, but it is part of xorg-server-utils, should be installed on all KaOS systems).

The next step is to change /etc/X11/xorg.conf appropriately. First, you must determine the PCI address of the NVIDIA card. Using lspci, check the NVIDIA entry:

lspci | grep NVIDIA

The first number you see, which should be formatted something like ##:##.#, is the PCI address. In /etc/X11/xorg.conf, however, the format must be modified so each number is one digit separated by colons (i.e. 01.0 would be written as 1).

Next edit /etc/X11/xorg.conf:

kdesu kate /etc/X11/xorg.conf

Section "ServerLayout"

Identifier "layout"

Screen 0 "nvidia"

Inactive "intel"

EndSection

Section "Device"

Identifier "nvidia"

Driver "nvidia"

BusID "PCI:PCI_address"

EndSection

Section "Screen"

Identifier "nvidia"

Device "nvidia"

Option "UseDisplayDevice" "none"

EndSection

Section "Device"

Identifier "intel"

Driver "modesetting"

EndSection

Section "Screen"

Identifier "intel"

Device "intel"

EndSection

The final step is to modify your ~/.xinitrc file to run two xrandr commands. Add the following two lines at the beginning of your .xinitrc:

kate ~/.xinitrc

xrandr --setprovideroutputsource modesetting NVIDIA-0 &

xrandr --auto &

Now reboot, and X should run. If you get a black screen after starting X, kill it and try starting X again (it may take several tries).

demm: I haven`t the archive /etc/X11/xorg.cong, and when i create like the tutorial and then modify the ~/.xinitrc, my system die

javierascua

demm: I've done all the tutorial but (always but) when i reboot, i get a black screen, and i don't know how to continue, please help me

demm

This is a trial, and might not work with all hybrid cards. But to be able to help, output is need from what was asked in your other thread.

When posting large output like these 2 posts, please use a pastebin service, or at least use code tags. I added code tags for you this time.

The installer does not pick up your graphics card at all......Did you choose non-free at the start of live-mode? But either way, it should have used nouveau/intel if you choose free, or install the non-free nvidia driver, neither one happened.

Did you try the other options mentioned in the tutorial, using only intel, or installing intel and nouveau? What was the result?

Did lspci | grep NVIDIA give you numbers that you used in your xorg.conf?

Why did you remove the stable kernel? Please keep that one always installed, much safer to have two kernel options when installing linux-next.

When you say black screen, do you have a blinking cursor? Did you try to go to tty1 (Ctrl-Alt-F1)? If that is possible, then login and run "sudo journalctl -b -p err", and post any error messages here. Next run "startx" from tty1, and post error messages from that too.

I'll look into why the installer does not pick up this card at all, see if there is anything I can change it the hardware detection scripts.

javierascua

demm: BusID "PCI

I've installed installing intel and nouveau and nothing

javierascua

demm: i run these two comands and

When i run "sudo journalctl -b -p err" these are the errors:

demm: I´m still with the problema and i don´t know how to do with my system to enabled all the effects (3d effects)

demm

Sorry not much news here, since no access to this hardware, still not clear what is going on that only vesa gets loaded.

javierascua

demm: what you mean about ¨since no access to this hardware¨?

demm

I have no access. What is reported so far does not give any indication why the hardware detection scripts do not find any drivers for this card.

javierascua

demm when i do in terminal lspci -d10de: -vvv comand the answer is

i want to know what to do, bacause i`m still with no 3d effects, thank for your help

demm

Do you use another distribution were this card works correctly? Can you check what drivers are in use there? Have you been able to get this card to work correctly when bumblebee was installed? When it works, works better with non-free nvidia or nouveau?

javierascua

I use chakra and the same problem, i can`t install manjaro kde (the screen is black after boot the livecd), opensuse don`t work

demm

That is interesting.....

So KaOS works as well or better than any other, without bumblebee in the repo.

There has to be a way to make this work better then.

Can you start live mode one more time, and use "free" for graphics. If you get to a working desktop with the vesa driver, try "sudo modprobe nouveau", then logout, login (use username live, password live) to restart X. See if nouveau loads then instead of vesa.

javierascua

demm: I start in live mode and use "free" for graphics, the i try in terminal "sudo modprobe nouveau" and the answer is: ERROR: could not insert 'nouveau': No such device

the truth is that i`m going crazy, the OS KaOS is beautiful and works fine, but i feel that I have always felt something lacking
