SDDM + nvidia-340xx = black screen - Failed to create OpenGL context

travnick · 2015-05-22 14:51:27

When I'm trying to use SDDM I see nothing but black screen (I see sddm and Xorg running).

It used to work some time ago, but one day it stopped.

I'm using nvidia-340xx drivers:

[travnick@travnick-lap ~]$ yaourt -Qs nvidia

Problem ~~solved~~ workaround:
After installing mesa-libgl (conflicts with nvidia-340xx-libgl) thes sddm starts (gdm as well)

=== edit:
but there is performance degradation (e.g. in Blender)

Sounds like a configuration issue. Was nouveau blacklisted? nvidia loaded in the initramfs?

travnick · 2015-05-31 16:21:42

How to check it?
As far as I remember I only installed nvidia drivers and it worked.

Scimmia · 2015-06-01 04:19:42

So yes, it's a configuration problem.

Don't think so because kdm used to work at the same time as sddm and gdm doesn't

travnick · 2015-06-02 23:23:57

The problem is that with mesa-libgl I'm using mesa implementation of libgl, not nvidia one - there is performance degradation ...

I've tried to add rcutree.rcu_idle_gp_delay=1 but it didn't helped.

The Xorg loads, nvidia module is loaded but sddm fails to start.
So the thing is that nvidia-340xx-libgl does not work with sddm and gdm but lxdm does. I wonder why?

I have not nouveau drivers installed:

[~]$ yaourt -Qs nouveau
multilib/lib32-mesa 10.5.6-1
    an open-source implementation of the OpenGL specification (32-bit)
extra/mesa 10.5.6-1
    an open-source implementation of the OpenGL specification

travnick · 2015-06-09 09:14:05

Bump, any solution for that?
Or is it maybe working for someone with the same configuration?

Soukyuu · 2015-06-09 12:12:59

It's working for me, I'm on 340xx nvidia drivers and using sddm+plasma. I even have nouveau installed in parallel (blacklisted).
I don't know if it makes any difference, but I'm using the -ck variant of the kernel and the nvidia driver. libgl part is still the same though:

$ pacman -Qs nvidia
local/lib32-libcl 1.1-1
    OpenCL library and ICD loader from NVIDIA (32-bit)
local/lib32-nvidia-340xx-libgl 340.76-1

    NVIDIA drivers utilities (32-bit)

    OpenCL library and ICD loader from NVIDIA
local/libvdpau 1.1-1
    Nvidia VDPAU library

travnick · 2015-06-09 14:13:11

I also switched to linux-ck in the mean time but nothing changed.
I wonder if there is any differences since you are using custom builds of packages (repo: local)

Soukyuu · 2015-06-09 18:46:53

The local repo is what I have installed, yaourt seems to do a "pacman -Ss" and only list stuff you have installed.
As Scimmia said, it looks like a local configuration issue. Try removing sddm and its configuration (-Rsn) and re-install it.

travnick · 2015-06-09 21:51:38

I've done that before and didn't help.

P.S.
Mine "yaourt -Qs" shows origin of package instead of "local".

Soukyuu · 2015-06-09 22:16:00

That's because you are using yaourt -Qs and not pacman -Qs like I do.

Does running glxgears work? It's in mesa-demos.

travnick · 2015-06-09 22:19:04

// oh I see, missed it.

glxgears, blender and other opengl stuff works. Plasma 2/Gnome also works but I need to use lxdm, SDDM and GDM are not working.

MrC · 2015-07-18 15:48:15

Not sure if you've fixed this but I had the same symptoms here on a Gentoo box today and after a bit of digging around noticed that systemctl output was showing a unit named session-c1.scope was in a status of loaded/active/abandoned and a description of "Session c1 of user sddm".

Suspected that sddm-greeter was running as sddm user and didn't have permission to access the video card so added the sddm user to the video group and rebooted. sddm-greeter now working as expected.

Might be worth a try?

travnick · 2015-07-18 22:37:24

I just realized that user I use is not in the video group. So if it works that way I won't be able to run any opengl app.

In the other hand, there is group vglusers and it match group of /dev/nvidia0 so I'll try that one.
