Mesa using llvmpipe for rendering with my 3 GPU, 6 display setup. How

I want to use the Intel onboard for doing the rendering. Using the proprietary nvidia driver is not an option.

Any advice on where I could look further, or how to solve this?

Re: Mesa using llvmpipe for rendering with my 3 GPU, 6 display setup. How

from your Xorg0.log :

[    24.151] (WW) intel(0): [DRI2] Direct rendering is not supported when VGA arb is necessary for the device
[    24.151] (II) intel(0): hardware support for Present enabled
[    24.151] (--) RandR disabled
[    24.151] (II) Found 2 VGA devices: arbiter wrapping enabled
[    24.156] (II) AIGLX: Screen 0 is not DRI2 capable
[    24.156] (EE) AIGLX: reverting to software rendering
[    25.241] (II) AIGLX: Loaded and initialized swrast
[    25.241] (II) GLX: Initialized DRISWRAST GL provider for screen 0

VGA arbiter wrapping is used if there is more then 1 card using the legacy vga device.
Looking at the outputs for your cards it seems one of your nividia cards ( NOUVEAU(G1): Chipset: "NVIDIA NVA8" ) has a vga connector, so you have 2 vga outputs (intel + nvidia).

try removing the nvidia card with the vga connector to verify if that's the problem cause.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?

Lone Wolf: Yes, I do have a nvidia card with VGA out. I should be able to blacklist it with the instructions at https://wiki.archlinux.org/index.php/No … tput_Issue.

Thanks!
