nvidia-prime problems with steam

[Samuele Giovanni Tonon]

hello,
if i launch steam on ubuntu 14.04 with nvidia-prime i get some errors:

1) swrast is not exposed:

$ LIBGL_DEBUG=verbose steam
Running Steam on ubuntu 14.04 64-bit
STEAM_RUNTIME is enabled automatically

libGL: Can't open configuration file /home/samu/.drirc: No such file or directory.
libGL error: failed to load driver: swrast
[...]

2) steam complains with this error (but loads anyway)

OpenGL GLX context is not using direct rendering, which may cause performance problems.
For more information visit https://support.steampowered.com/kb_article.php?ref=9938-EYZB-7457.

steam itself works, however i'm not able to play games but i'm not sure if this is due to previous errors or it is due to some missing 32 arch libs since steam officially supports bumblebee and not nvidia-prime.

Let me know if you need more information

Regards
Samuele

please attach the following files:

1) /var/log/gpu-manager.log
2) the output of the "dkms status" command
3) the output of the "dmesg" command

and this is dmesg output

[Alberto Milone (albertomilone)]

Everything seems to be ok.

Please type the following commands:

sudo apt-get install mesa-utils:i386

ldd $(which glxinfo)

And attach the output of the second command.

This looks wrong:
libGL.so.1 => /usr/lib/i386-linux-gnu/mesa/libGL.so.1 (0xf772c000)

as it should really point to the NVIDIA library. No wonder it doesn't work.

Please attach the output of the following command:

update-alternatives --display i386-linux-gnu_gl_conf

The alternatives seem to be fine.

What's the output of the following command?

ldconfig -p | grep -i gl | grep -v x86-64

[Samuele Giovanni Tonon (samu-linuxasylum)]

sure

[Alberto Milone (albertomilone)]

It looks like a misconfiguration issue (something is interfering and ldconfig finds the mesa library before NVIDIA's).

Please attach the output of the following commands:

1) ls /etc/modprobe.d/*
2) grep -i nvidia /etc/modprobe.d/*
3) grep -i mesa /etc/modprobe.d/*

[Samuele Giovanni Tonon (samu-linuxasylum)]

doh, since you mentioned ldconfig looking for mesa libs before nvidia i checked out my /etc/ld.so.conf.d/
and found, it's my fault:

i had a conf file named steam.conf with

/usr/lib32
/usr/lib/i386-linux-gnu/mesa
/usr/lib/i386-linux-gnu/dri
/usr/lib/i386-linux-gnu/gallium-pipe

inside .

removing that file and running ldconfig again as root solved the problem

it was a PEBKAC issue :-(

Thank you for your support

Cheers
Samuele

[Alberto Milone (albertomilone)]

No problem ;)

[Frieder Bluemle (frieder-bluemle)]

I had a similar issue and this thread helped me to resolve it.

For me it was a symlink in /etc/ld.so.conf.d/
i386-linux-gnu_GL.conf -> /etc/alternatives/i386-linux-gnu_gl_conf
The file contained some mesa directory reference which caused Steam to fail at startup.

Steps to fix:
sudo unlink i386-linux-gnu_GL.conf
sudo ldconfig

Thanks.

Thanks, #13 solution resolved my problem which occured apparently after upgrade to ubuntu 15.04

[sabby (sabby)]

Also wanted to thank #13, no idea how this happened on my 14.04 system but it did, saved me a lot of searching.

[Giambo (ggiambo)]

After spending hours looking for a solution, this thread helped me !
Just removed /etc/ld.so.conf.d/steam.conf and run ldconfig, everything now is OK !

Using Ubuntu 15.04 (Linux Mint 17.2)

[zachtmartin (zachtmartin)]

Here's one of the errors I was getting when trying to load up steam:

libgl error: failed to load driver: swrast

After much searching this hidden thread saved the day. I deleted the steam.conf file as in #11 and then ran ldconfig. Fixed! Thanks to all over a year later.
