 |
|
Hi,
I wanted to try wayland with a window manager.My first try was to try to make it work with the nvidia drivers by installing dev-libs/wayland , gui-wm/sway, x11-base/xwayland. In /etc/portage/make.conf, there is:
| Code: | USE="X dist-kernel binary pulseaudio"
VIDEO_CARDS="nvidia"
|
Sway refused to start, even with --unsupported-gpu (it found no GPU at this point). Xorg could still be started. My second try was to use nouveau with VIDEO_CARDS="nouveau" and rebuilding everything with emerge -auvDN @world. Sway fails to start with:
| Code: | libEGL warning: MESA-LOADER: failed to open crocus: /usr/lib64/dri/crocus_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib64/dri, suffix _dri)
00:00:00.338 [ERROR] [wlr] [EGL] command: eglInitialize, error: EGL_NOT_INITIALIZED (0x3001), message: "DRI2: failed to load driver"
libEGL warning: MESA-LOADER: failed to open crocus: /usr/lib64/dri/crocus_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib64/dri, suffix _dri)

00:00:00.338 [ERROR] [sway/server.c:79] Failed to create renderer
|
Even though gui-libs/egl-wayland is installed ! At this point, I can still start X.
Installing media-libs/mesa-amber did not help and replacing USE="X" by USE="wayland" fails to build some package. At some point, I could no longer start X so I went back to xorg with nvidia.
1. Is there a way to make wayland work with nvidia drivers with a window manager ?
2. Otherwise, how can I make it work with nouveau ?
Thanks !

That's coming from Mesa. The loader is looking for an Intel driver, crocus_dri.so, and doesn't find it. Is this actually an Optimus computer, or does it also have an Intel card?

| There is also an Intel card (HD graphics 4600), good catch. Is there a way to force wayland to use the NVIDIA card ? |

As a reference, how are you doing that for X11?

Xorg found there were no intel driver, so it went back to the default driver.
And I just realized it was not (never ?) picking up nvidia. Xorg uses the "modesetting" module :/
With USE="nvidia intel", I can get sway to start with sway --unsupported-gpu. That's a good point.
However, I still cannot make xorg use nvidia instead of modesetting. Here's what I've tried :
- emerge @module-rebuild
- adding nvidia to /etc/modules-load.d/video.conf,
- custom xorg.conf : https://wiki.gentoo.org/wiki/NVIDIA/Optimus/xorg.conf
- xorg.conf generated by the nvidia tools
So the initial problem is solved but there's a new one :/ |

Be aware that, because media-libs/mesa with VIDEO_CARDS="nvidia intel" (is that what you meant?) willl now give you the crocus driver, there's a possibility that sway is using the Intel card.

If you really have an Optimus computer, both the modesetting and proprietary nvidia drivers would be used, and, because the nvidia card is not driving a display, two extra xrandr commands are needed, in addition to a custom xorg.conf file, before Xorg starts. They are also in the Wiki article about Optimus.

Yes, my idea was to use intel by default instead of trying to make nvidia drivers works.
I'm not sure the computer has an Optimus but using the two xrandr commands on the wiki https://wiki.gentoo.org/wiki/NVIDIA/Optimus
| Code: | xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto |
and a Xorg.conf generated by nvidia-xconfig --prime.
Xorg does starts but only with modesetting. As it works, I can leave as is |

from https://github.com/swaywm/sway/wiki
| Quote: | I have a multi-gpu setup (like intel+nvidia or intel+amd) and sway does not start
Unless specified otherwise, wlroots will choose a card for you and you could have a similar message in sway's log:
To use a different default card (listed in /dev/dri/), set this environment variable before starting sway:
WLR_DRM_DEVICES=/dev/dri/card1 sway
It's likely that you want sway to use the integrated (Intel) card, because probably that's the only one directly connected to the laptop monitor. However, the mapping between node names in /dev/dri/ and actual cards isn't guaranteed to be the same across reboots.
This script detects which is the device path of the integrated card and launches sway accordingly:
#!/bin/sh
val=$(udevadm info -a -n /dev/dri/card1 | grep boot_vga | rev | cut -c 2)
WLR_DRM_DEVICES="/dev/dri/card$val" sway
You can also configure multiple graphics cards like so:
WLR_DRM_DEVICES=/dev/dri/card0:/dev/dri/card1 sway
The first card is used for actual rendering, and display buffers are copied to the secondary cards for any displays connected to them. |
here's my .profile file in my users home with some entries:
| Code: | export MOZ_ENABLE_WAYLAND=1
export MOZ_DBUS_REMOTE=1
export XDG_CURRENT_DESKTOP=sway
export XDG_SESSION_DESKTOP=sway
export XDG_SESSION_TYPE=wayland
export EDITOR=/usr/bin/geany
export BROWSER=firefox
export TERM=sakura |
just add the above mentioned variable to this file.
better use Intel Card - less headaches !
start Sway from TTY as user via sway -d 2> ~/sway.log - you'll get more infos.

Thanks for the tips ! Somehow your script was not working so I removed nvidia drivers for nouveau. Now both Xorg and waylaynd starts without issue so I'm marking the issue as solved.
For future reference, migration was done by
- VIDEO_CARDS="nouveau intel"
- emerge sys-firmware/nvidia-firmware
- emerge -auvDN @world
- mv /etc/modprobe.d/nvidia.conf /etc/modprobe.d/.nvidia.conf
The last command was the most important as nvidia was still being used. |
