I’ve had a lot of trouble with bumblebee lately but it looks like it is finally almost working.
optirun glxspheres output:
Polygons in scene: 62464
Xlib: extension "GLX" missing on display ":8".
ERROR (610): Could not obtain RGB visual with requested properties
Perhaps there is an easy fix for this…
Can you please post /var/log/Xorg.8.log? This should point to the problem.
My suspicion: did you install the standard proprietary nvidia driver?
You shouldn’t! This will break Mesa’s and intel’s GLX. And the driver itself will probably not even work as it has provisions to bail out on Optimus systems, the packages in the standard nvidia repo at least.
If you want to use the nvidia driver with Bumblebee, install the nvidia-bumblebee package from the Bumblebee repo.
More information about how exactly you installed Bumblebee would be helpful as well, and some information about your openSUSE version and hardware, especially what nvidia card.
nvidia-bumblebee gave errors for me (something like permission denied while I clearly was member of the video,bumblebee group)
I installed the nvidia drivers and bumblebee from the opensuse 13.2 repository (after I notices bumblebee was also in the opensuse repository)
I blocked nvidia-glG03 (after uninstalling it)
I am using the default kernel (I switched to the default kernel because I hoped this might fix some dependencies or something)
OpenGL is working perfectly on display :0 with my Intel HD (including GLX)

I installed the nvidia drivers and bumblebee from the opensuse 13.2 repository (after I notices bumblebee was also in the opensuse repository)
Hm? There is no nvidia driver in the opensuse 13.2 repository.
I think you mean the nvidia repo?
I blocked nvidia-glG03 (after uninstalling it)
And that’s why GLX is not working.
Didn’t I explain to you already that installing the standard nvidia driver packages without nvidia-glG03 will make it impossible to run 3D applications on the nvidia chip?
You can use the nvidia chip only for CUDA that way.
I am using the default kernel (I switched to the default kernel because I hoped this might fix some dependencies or something)
The default kernel has exactly the same dependencies.
The difference is just that the desktop kernel has tuned some settings for desktop use, like lower latency. But I can’t tell you the details either.
OpenGL is working perfectly on display :0 with my Intel HD (including GLX)

Here’s your error.
/usr/lib64/nvidia/xorg/modules/extensions/libglx.so cannot be loaded, because it is not installed. It is part of the package nvidia-glG03 (which installs it to a completely different place btw, so even installing it won’t help you with Bumblebee), but installing that will break your intel GLX and Mesa’s OpenGL software renderer.
As your desktop runs on the intel chip, this is really a bad idea, and you noticed that already anyway I think.
One thought:
As Bumblebee apparently wants to load libglx from /usr/lib64/nvidia/xorg/modules/extensions/, you could download the nvidia-glG03 package, extract it with Ark or File-Roller e.g., and copy the files to /usr/lib64/nvidia/xorg/modules/extensions/ by hand (create that directory if it doesn’t exist). They should not disturb Mesa then, and might work with optirun…
The nvidia rpm is indeed from the nvidia repo but bumblebee is also included in the opensuse repo.
I installed nvidia-glG03 because it seemed the only obvious solution to me. It looks to me like it doesn’t break mesa at all (perhaps a symlink is required to get nvidia-glG03 working?)
I will try your suggestion of manually installing the shared objects.
Hmm, interesting, the rpm of nvidia-glG03 contains this file:
/lib64/xorg/modules/extensions/nvidia/nvidia-libglx.so
Perhaps bumblebee is outdated…
Contents of the rpm:
http://paste.opensuse.org/view/raw/23253921
I thought you did not install it?
It is true that on 13.2 a symlink is necessary to get nvidia-glG03 working, yes. This is done via “update-alternatives”, the package should do that on installation.
But since recently there’s a check in the package whether it is installed on an Optimus system, and it doesn’t activate its libglx in that case.
Changelog entry:
Wed Nov 5 13:01:10 UTC 2014 - sndirsch@suse.com
- On Optimus systems disable NVIDIA driver/libs completely by
default (bnc#902667)
I will try your suggestion of manually installing the shared objects.
Since you installed nvidia-glG03 now, creating some symlinks should be fine as well.
I had a look at the package again, and it installs to /usr/X11R6/lib64/libGL.so*.
So either copy the files from there to /usr/lib64/nvidia/xorg/modules/extensions/, or create symlinks accordingly. And something similar should be done for the 32bit versions as well (lib instead of lib64) I suppose.
But I cannot guarantee you that this will work.
Yeah, right. I forgot to mention that in my previous post. You’d have to rename this to libglx.so though after you copy it to /usr/lib64/nvidia/xorg/modules/extensions/. Or create a corresponding symlink.
I have no idea where Bumblebee/optirun would load libGL from though, but you could try the same directory.
Perhaps bumblebee is outdated…
No. Bumblebee is just not designed to be used with the official nvidia driver packages.
nvidia-bumblebee does install the files to /usr/lib64/nvidia/xorg/modules/extensions/.
PS: Forget about libGL.*. The nvidia packages add /usr/X11/lib(64) to the linker path, so they should be found where they are.
And this is done even on Optimus systems.
I believe that on your system Mesa’s libGL (and libEGL and others) is not found now any more, thus breaking applications that want to use it on the intel chip.
I still have mesa installed without any conflicts. I installed nvidia-glG03 before, them removed and blocked it, and now reinstalled it. I copied the libglx to the right directory like this:
sudo cp /usr/lib64/xorg/modules/extensions/nvidia/nvidia-libglx.so /usr/lib64/nvidia/xorg/modules/extensions/libglx.so
And optirun is working again! I think I got a slightly higher framerate before but I’m cool with this… Perhaps I can even install CUDA now (since bumblebee is now using the nvidia driver)
I locked all nvidia/bumblebee packages to hopefully avoid future capability issues. Or do you think I should symlink libglx and keep updating nvidia?
BUT: WebGL is not working on firefox and chrome. bumblebee uses vgl (primusrun returns: primus: fatal: failed to acquire direct rendering context for readback thread)
Perhaps I also have to copy the other nvidia-glG03 shared objects? (perhaps a very dumb question but I’m not really an expert at this stuff)
How do you know that there aren’t any conflicts?
Normally, after you install nvidia-glG03, nvidia’s libGL (libEGL, and so on) is used instead of Mesa’s one, by all programs.
The package adds a file to /etc/ld.so.conf.d/ to make the linker prefer the libraries in /usr/X11R6/lib(64) over anything else.
If this file is present, nvidia’s libGL will be used also by applications running on the intel chip, which will not work.
Maybe the file does not get installed on Optimus systems as well now, but I haven’t seen a change regarding this in particular (maybe I overlooked it though).
I installed nvidia-glG03 before, them removed and blocked it, and now reinstalled it. I copied the libglx to the right directory like this:
sudo cp /usr/lib64/xorg/modules/extensions/nvidia/nvidia-libglx.so /usr/lib64/nvidia/xorg/modules/extensions/libglx.so
And optirun is working again!
Good to hear!

As I already wrote, I am not sure whether CUDA will work at all in combination with Bumblebee.
There is no difference betweed the nvidia driver packages and nvidia-bumblebee. Both are the same proprietary nvidia driver (different versions though), the files are just packaged differently and install to different places. And nvidia-bumblebee sets up dkms for automatic recompilation of the kernel module after kernel updates, whereas the nvidia packages use the so-called “weak-updates links” to totally avoid a recompilation (like all other openSUSE kmp packages do as well).
So it should actually work with both from this point of view.
As a side-note: I just noticed that there are cuda packages available in the home:Bumblebee-Project repos as well. This might indicate that it should indeed work…

You could symlink libglx in any case, no need to have it twice on your system… 
Updates should be safe, but I cannot guarantee you that of course.
Yes, I have heard reports of this already, I think I mentioned this in your other thread.
I’m not sure whether your problem is exactly the same, whether this is specific to Optimus/Bumblebee, or a general problem with nvidia (the reports I read were all with the nvidia driver, but I don’t remember whether all of those were Optimus systems or not).
Perhaps I also have to copy the other nvidia-glG03 shared objects? (perhaps a very dumb question but I’m not really an expert at this stuff)
No. Again, libGL should be found in /usr/X11R6/lib64/. But try this as a test:
LD_LIBRARY_PATH=/usr/X11R6/lib64 optirun xxx
nvidia’s libGL should then be found in any case.
LD_LIBRARY_PATH=/usr/X11R6/lib64 optirun xxx runs glxspheres 2-3 times faster!!! It also makes WebGL work in Firefox (not in chrome tough, but that’s a chrome issue I think)
