 Posted: Thu Nov 18, 2021 2:26 pm Post subject: GNOME not using Wayland |
 |
|
Hi,
I have a computer with an NVIDIA GeForce GT 730 graphics card, which is restricted to older nvidia-drivers-470. I understand that it should support Wayland, but GNOME is falling back to X11, and I cannot find why.
Wayland is in my USE flags:
| Code: | | USE="... wayland ..." |
I am activating nvidia_drm modesetting support in the kernel command line:
| Code: | | GRUB_CMDLINE_LINUX="... nvidia-drm.modeset=1" |
My | Code: | | /lib/udev/rules.d/61-gdm.rules |
is not disabling wayland for nvidia:
| Code: |
# disable Wayland on Hi1710 chipsets
ATTR{vendor}=="0x19e5", ATTR{device}=="0x1711", GOTO="gdm_disable_wayland"
# disable Wayland if modesetting is disabled
IMPORT{cmdline}="nomodeset", SUBSYSTEM=="drm", KERNEL=="card[0-9]*", GOTO="gdm_disable_wayland"
# Disable wayland when nvidia modeset is disabled or when drivers are a lower
# version than 470, in any case always prefer Xorg
KERNEL!="nvidia_drm", GOTO="gdm_nvidia_drm_end"
SUBSYSTEM!="module", GOTO="gdm_nvidia_drm_end"
ACTION!="add", GOTO="gdm_nvidia_drm_end"
# disable wayland if nvidia-drm modeset is not enabled
ATTR{parameters/modeset}!="Y", GOTO="gdm_disable_wayland"
# disable wayland for nvidia drivers versions lower than 470
ATTR{version}=="4[0-6][0-9].*|[0-3][0-9][0-9].*|[0-9][0-9].*|[0-9].*", GOTO="gdm_disable_wayland"
GOTO="gdm_prefer_xorg"
LABEL="gdm_nvidia_drm_end"
GOTO="gdm_end"
LABEL="gdm_prefer_xorg"
RUN+="/usr/libexec/gdm-runtime-config set daemon PreferredDisplayServer xorg"
GOTO="gdm_end"
LABEL="gdm_disable_wayland"
RUN+="/usr/libexec/gdm-runtime-config set daemon WaylandEnable false"
GOTO="gdm_end"
LABEL="gdm_end"
|
And Wayland is not disabled in | Code: | | /etc/gdm/custom.conf |
:
| Code: |
# GDM configuration storage
[daemon]
# Uncomment the line below to force the login screen to use Xorg
#WaylandEnable=false
[security]
[xdmcp]
[chooser]
[debug]
# Uncomment the line below to turn on debugging
#Enable=true
|
What else do I need to do to enable Wayland in GNOME?
Thanks. |

nvidia-drivers will already enable modeset=1 with USE=wayland (unless you modified /etc/modprobe.d/nvidia.conf), so it's not something you need to set yourself
you do have VIDEO_CARDS=nvidia set too, right? This is notably needed on mutter, and preferably xwayland too.
With my 1070, 470.xx, and gnome profile -- gdm uses wayland out-of-the-box (and "GNOME" starts a wayland session, have to select "GNOME on Xorg" if I want xorg) except for having to set VIDEO_CARDS, no other settings.. didn't mess with udev rules or stuff like that (this is partly because the udev rule didn't work in the first place unless gdm is restarted, recently it now stay on wayland even if restarted though).
Not that I tested this all that much, I try it now and then but I still use Xorg (for now, will migrate in a few years) and don't actually use gnome. Also never tried EGLStream with Kepler cards, or dual gpu setups (if you got some intel gpu in there, it can mess with detection from what I heard). Possible there's some other problem here. |

I did not have this line originally, it is one of the things I've tried to fix the issue. I have not touched /etc/modprobe.d/nvidia.conf, so I'll remove it.

Yes, I forgot to add it to my post. I have
| Code: | | VIDEO_CARDS="intel i965 iris nvidia" |

I have a dual gpu setup, the Nvidia and in integrated intel. Do you think that could be the root of this issue? |

Could you try again with nvidia-drivers-470.86-r1? A change I did (for another reason) may or may not have improved this at same time.
Otherwise, don't think I can help. I don't have hardware with that kind of setup to know how to solve these issues. |

I've tried this version of the driver, and the problem persists.
I am checking for messages using | Code: | | dmesg | grep -i drm |
and I got the following:
| Code: | | [drm:drm_new_set_master] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Failed to grab modeset ownership |
I think it might be related, but I am not sure how to fix it. |

I've been able to fix the dmesg error by reconfiguring the kernel with CONFIG_DRM=n and re-compiling it. But now I have the following error:
| Code: | | nvidia_drm: unknown parameter 'modeset' ignored |
