symbol lookup error: /usr/lib/x86_64-linux-gnu/glxosd/libglxosd-plugins-nvidia-support.so: undefined symbol: XextFindDisplay

Running glxosd with the nvidia 337.25 drivers via optimus/primus. Crashes immediately. Output from all varations of primusrun/optirun is the same.

$ primusrun glxosd glxgears [GLXOSD] Loading libglxosd-plugins-libsensors-support.so [GLXOSD] Loaded libglxosd-plugins-libsensors-support.so [GLXOSD] Loading libglxosd-plugins-nvidia-support.so [GLXOSD] Loaded libglxosd-plugins-nvidia-support.so glxgears: symbol lookup error: /usr/lib/x86_64-linux-gnu/glxosd/libglxosd-plugins-nvidia-support.so: undefined symbol: XextFindDisplay

Not sure whether the program needs to be updated the newer drivers, or if it's a problem with bumblebee, but figured i'd mention it here.

[jonchampagne]

I should also add that I'm on linux mint 17, and completely up to date.

[nickguletskii]

Could you please try running

glxosd primusrun glxgears

?

I can't test Primus on my machine because I don't have Optimus.

[jonchampagne]

As I stated, identical output for all variations of putting primusrun/optirun before and after the glxosd command.

[nickguletskii]

Oh, okay, sorry.

I did some searching and it seems like I am not at fault here. I don't use XextFindDisplay in my code, My guess is that it is called from XOpenDisplay, but I haven't verified that.

Please check that libxext6 is installed. If it isn't, please install it and try again.

[jonchampagne]

Yup it is. Must have gotten pulled in by the packages in the ppa or something else. Just for good measure, i installed libxext6-dbg, but that doesn't seem to have made any more debug output.

[nickguletskii]

Thank you very much. I will add this library to the dependency list tomorrow.

[jonchampagne]

Alrighty. Still not working, but great response time! Wouldn't have expected to hear back for a day or two with such a small project.

[nickguletskii]

Hmm, what isn't working? I know that this refuses to work with some applications, but if you have any error messages, please do create an issue because I am planning to try and fix GLXOSD not working with some applications pretty soon.

[jonchampagne]

It's still outputting the same thing with any program i run on my nvidia card with primusrun/optirun. Same output as the first post.

[nickguletskii]

The last shot in the dark for tonight: try running

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libXext.so.6 glxosd primusrun glxgears

I doubt this will help, but who knows? Anyway, I will look into this issue further tomorrow.

[jonchampagne]

That seems to have worked! No idea why the library wasn't getting loaded, but it works now. Thanks a ton :D

[nickguletskii]

No problem, thanks for reporting the issue! I will try to think of a way to fix this.

[nickguletskii]

This seems to be an isolated issue. I can't replicate this on Mint 17. If someone else has this issue, please let me know.

[minj]

I confirm this issue. Running Lubuntu 14.04 amd64. Nvidia 337.25-0ubuntu1~xedgers14.04.2 Bumblebee 3.2.1 libxext6 2:1.3.2-1

Workaround confirmed.

[minj]

However, that's only good for glxgears. Can't run steam apps.

[nickguletskii]

GLXOSD v3 potentially fixes the problem. I would be very grateful if anyone could confirm one way or another.

[nickguletskii]

XextFindDisplay is no longer used in version 3, therefore this issue is obsolete.

[Yaksinikos]

XextFindDisplay is no longer used in version 3, therefore this issue is obsolete.

But it still do not work. v. glxosd 3.2.2-1
