Solved Still can't get Wayland working with NVidia.

S

scottro

I had Wayland working with NVidia for while, then it stopped. I've pretty much followed the handbook.

Installed wayland and seatd. Then I installed labwc and dwl. They pulled in other things like wl-roots, I don't remember exactly.
pciconf -lv shows
GP108 [GeForce GT 1030]
XDG_RUNTIME_DIR is /run/user/$(id -u) set in my .bashrc.

I start the seatd service.

But when I try to start say dwl, I get the message
00:00:00.007 [ERROR] [backend/backend.c:210] Found 0 GPUs, cannot create backend 00:00:00.007 [ERROR] [backend/backend.c:376] Failed to open any DRM device couldn't create backend
I'm wondering if it's just my hardware, or if I'm missing something.

It's not too important to me, I much prefer X11, but I'd just like to be able to do it if I wanted.

EDIT: (forgot more NVidia information.

pkg info |grep -i nvidia gives me
nvidia-driver-550.54.14 nvidia-drm-515-kmod-550.54.14_1 nvidia-drm-kmod-550.54.14 nvidia-settings-535.146.02_1 nvidia-xconfig-525.116.04
and my /etc/rc.conf has
kld_list="nvidia-drm"

Hi Mate

Im running dwl on a Dell XPS 15 with an nvidia gpu

Freebsd 14.1 creates the XDG_RUNTIME_DIR and exports its location

So you dont need to export the XDG_RUNTIME_DIR in your shell config anymore
if your on Freebsd 14.1 comment out the XDG_RUNTIME_DIR in your ~/.bashrc

reboot and run

Code: 
printenv

and you should see the xdg runtime dir is set

Code: 
XDG_RUNTIME_DIR=/var/run/xdg/djwilcox

The location is /var/run/xdg/username
where username is your username

Code: 
Yes Master ? sudo ls -l /var/run/xdg

This is my rc.conf

Code: 
# kld list
kld_list="nvidia-modeset nvidia-drm linux linux64 i915kms"
# wayland
seatd_enable="YES"
# dbus
dbus_enable="YES"
linux_enable="YES"

and i start dwl like

Code: 
exec dbus-launch --exit-with-session dwl -s 'dwlb -font "monospace:size=16"'

the -s dwlb start the dwl bar

Code: 
dwlb-s20240516                 Feature-complete bar for DWL

wayland packages

Code: 
sudo pkg install wayland wayland-protocols seatd wlroots qt5ct qt5-wayland

freebsd dwl wayland tiling window manager install with patches in a separate git branch. the reason why you need to build dwl on freebsd rather than using the port or packages is because the dwl package lets you set an variable called DWL_HOME_CONFIG that points to a dwl config.h file which...

My thanks to all who responded. NapoleonWils0n, unfortunately, it still didn't work though I tried with all your suggestions. But thanks for letting me know I don't have to set the XDG_RUNTIME_DIR variable. And yes it did show as you said it would , /var/run/xdg/<username>.
Alain De Vos, thanks for letting me know that it doesn't work for you either, it may be something with our hardware, though I haven't tried on Linux with NVidia.
As I said, it's more something I'd be interested
 
Having the XDG_RUNTIME_DIR automatically created and the location exported is really useful
a lot of people miss the step of setting it and exporting the location in their shell config

and then wonder why wayland isnt starting
 
i never noticed that pkg-message

i have nvidia-modeset in the rc.conf kld_list

maybe i should look at adding

Code: 
hw.nvidiadrm.modeset=1

to

Code: 
/boot/loader.conf

Code: 
Yes Master ? sysctl hw.nvidiadrm
hw.nvidiadrm.fbdev: 0
hw.nvidiadrm.modeset: 0


cheers for pointing that out mate,
going to add to my loader.conf
 
I see that I never mentioned in this thread that I also tried adding the hw.nvidadrm.modeset=1 to /boot/loader.conf, but I did try that as well, probably in July when dandelion first mentioned it.
 
It seems to miss a pkg x11/linux-nvidia-libs:
Code: 
~> pkg info|rg nvidia
linux-nvidia-libs-550.54.14    NVidia graphics libraries and programs (Linux version)
nvidia-driver-550.54.14        NVidia graphics card binary drivers for hardware OpenGL rendering
nvidia-drm-61-kmod-550.54.14_1 NVIDIA DRM Kernel Module
nvidia-drm-kmod-550.54.14      NVIDIA DRM Kernel Module
nvidia-settings-535.146.02_1   Display Control Panel for X NVidia driver
 
OP, what did you do between working and non-working states?
If you somehow updated kernel (regardless from src or via freebsd-update)?
If yes, did you rebuild all x11/nvidia-driver, graphics/nvidia-drm-515-kmod and graphics/drm515-kmod from ports?

Can you see the existnce of (at least) /dev/dri/card0?

If any kind of mis-matches exist (including with which src commit they were built), /dev/dri/ directory and its contents should not appear, thus not working.
 
T-Aoki, I did update packages. I don't really remember when this happened, I didn't post just after it happened, I posted probably a few weeks after it happened. I do have /dri/card0
I waited because a) it's not that important to me (so again, many thanks to all who have offered help for something that I'm not too worried about) and b) I figured that some update had broken it, so there would probably be an update to fix it, but after a couple of updates of various wayland related packages it still didn't work.

RhfUsQnPbC I just tried installing the linux-nvidia-libs but that didn't help. Thanks for the suggestion though.
 
If /dev/dri/card0 exists then may be it's not accessible by the current user: either not part of video group or lacking group read/write bits.
 
No, I'm definitely in the video group
Code: 
ls -l /dev/dri/card0
lrwxr-xr-x  1 root wheel 8 Jul 27 11:22 /dev/dri/card0 -> ../drm/0

But /dev/dri/card0 indeed doesn't have group write permissions. Furthermore, it is symlinked to /dev/drm/0, so it might be helpful to know the permissions there.

my permissions

Code: 
Yes Master ? ls -l /dev/dri/card0

i did find this post on the forum

Thinks for you reply, I have solved this problem.

The reason is my intel integrated gpu has been disabled in bios. Opened it that all is ok.

dont know if that helps
 
I just tried to chown and while it gave me no error messages, it didn't change the ownership. It is still listed as
lrwxr-xr-x 1 root wheel 8 Jul 27 11:22 /dev/dri/card0 -> ../drm/0

I was able to chang permissions on /dev/drm/0
Code: 
 ls -l /dev/drm/0
crwxrwxr-x  1 root video 0x66 Jul 27 11:22 /dev/drm/0

But still no luck with Wayland here. NapoleonWils0n that post doesn't seem relevant to my issue, but thanks for the suggestion.
adorno thank you for your suggestions as well. I do appreciate everyone who is offering possibilities to fix it.
