[solved] Issue: primus, libGl.so.1 or something else??

[@ttila]

Hi!!!!!
This is my first post, i use Debian "Buster" on a PC with a Geforce 1050ti and a laptop Lenovo g580 (Geforce 635M).
On both of them i play with Filghtgear and Urbanterror but I get only troubles with the Lenovo, everything goes smooth with the PC.
When i launch flightgear with (antialiasing 2x, nothing else):

Code: Select all

optirun -b primus fgfs --prop:/sim/rendering/multi-sample-buffers=true --prop:/sim/rendering/multi-samples=2 --log-level=debug

........
Using stock OSG implementation of GraphicsWindow
StatsHandler::StatsHandler() Setting up GL2 compatible shaders
initializing cloud layers
Using initial window size: 1024 x 768
Error: Not able to create requested visual.

getDefaultWindow: failed to create GraphicsContext
Error: Not able to create requested visual.

getDefaultWindow: failed to create GraphicsContext
CameraGroup::buildGUICamera: failed to build a window
Enabling ATI/AMD viewport hack
.........

If antialiasing is disable, Flightgear starts

Code: Select all

optirun fgfs

Using the intel video card and anti aliasing on, it fails

Code: Select all

fgfs --prop:/sim/rendering/...

Now with urban terror:

Code: Select all

primusrun /UrbanTerror43/Quake3-UrT.x86_64

Again it runs with the integrated Intel video card.
i repeat no problems with the Geforce 1050ti, so is it a primus or a libGl.so.1 issue?

Primus requires the libgl1-nvidia-glx package, instead of the libgl1-nvidia-glvnd-glx variant used by my Geforce 1050ti.
The bumblebee.conf file seems well configured.

Even that this is not directly related to Debian itself, take a look at the own game forum about that mobile video card:

it is my post, i solved it whit those suggestions but now i get it again. i think it is a issue of OS not of the sim,
Thanks anyway

I may suggest a good direct derivation distro (that uses Debian as main repository, offering only software in addition) that have a gaming aimed version:
https://sparkylinux.org/download/rolling/#special

But also have all three flavors of debian, so you can also download the "buster" compatible version, but is intended for people with more knowledge, like Debian unstable is, so I recommend at least the special testing above, or Debian testing with non-free repositories for gaming propouse.

Can you please edit the topic and add [SOLVED] Into the begging? Thanks.

I want to continue using a pure dedian distro, i think there is a bug i'll send a mail to the debian mailing list. And it isn't solved

Finally from the mailing list a holy man gives to me a workaround:

What happens if you install the "mesa-utils" package and run:

optirun glxinfo | grep OpenGL

does it say Nvidia as the vendor?

Primus is in a broken state in Sid, has been for a while, so it is probably the same in Testing now. If you can't get it to work (I gave up) because the "non-glvnd" and "glvnd" Nvidia variant conflict, you can use virtualGL as a workaround.

If you need to go that way just uninstall primus (but keep bumblebee), make sure the "glvnd" (not "non-glvnd") variant of the Nvidia packages are installed, and download the .deb packages for virtualGL here:

https://sourceforge.net/projects/virtualgl/files/

If I presume you are on 64bits (amd64) system you need both "virtualgl-[version]-amd64.deb" and "virtualgl32-[version]-amd64.deb" if you are running 32bits programs and have Nvidia 32bits compatibility packages installed.
After installing the virtualgl packages, and maybe a reboot, the "optirun glxinfo" command above should report Nvidia as OpenGL vendor, and your programs should work properly.

Simply install the virtualgl package and use the virtualgl bridge with:

Code: Select all

optirun -b virtualgl 

followed by the app name.
