Looks like you're using a Intel/NVIDIA GPU combination with outputs connected to NVIDIA GPU,but these outputs not being used at all. Also it looks like suse-prime or suse-prime-bbswitch package is being installed. And both drivers, modeset (for intel) and nvidia (proprietar driver for NVIDIA) are loaded. I suggest to uninstall suse-pirme/suse-prime-bbswitch package, since this is only useful for Optimus systems (NVIDIA GPU only used for faster rendering) and try again. If this doesn't help, I suggest trying to disable NVIDIA GPU in your BIOS/firmware. If this doesn't help either try to disabled Intel GPU in your BIOS/firmware. -- You are receiving this mail because: You are on the CC list for the bug.

Skype seems to have the same problem - not too surprising, I guess!?

Maybe same toookit? I don't know. (In reply to Tilman Vogel from comment #12)

Plus, that setup has worked flawlessly with the earlier Tumbleweed. It's definitely a regression on the OS/library side and cannot be explained by BIOS/firmware issues alone.

This is only meant as a workaround. -- You are receiving this mail because: You are on the CC list for the bug.

After gpasswd -a <me> bumblebee, I can "optirun teams" and that works! Even though I am running with "prime-select nvidia" anyway.

Currently I am running without any "suse-prime-*" or "bbswitch" and no explicit X video config and the default config seems to configure GPU offloading correctly, so I get

glxinfo | grep vendor server glx vendor string: NVIDIA Corporation client glx vendor string: NVIDIA Corporation OpenGL vendor string: NVIDIA Corporation

I found out that I can run teams successfully using

__GLX_VENDOR_LIBRARY_NAME= teams

which implies Mesa GL:

__GLX_VENDOR_LIBRARY_NAME= glxinfo | grep vendor server glx vendor string: SGI client glx vendor string: Mesa Project and SGI OpenGL vendor string: Intel Open Source Technology Center

I am still puzzled that this does not affect other GL apps. I can run glxgears fine both ways. -- You are receiving this mail because: You are on the CC list for the bug.

In nvidia mode of suse-prime I cannot reproduce that issue. Neither with teams nor with skype. But I have issues in intel mode with PRIME Render Offload. https://download.nvidia.com/XFree86/Linux-x86_64/435.21/README/primerenderof... For vulkan apps I need to uninstall package libvulkan_lvp package, since Mesa's lavapipe (software rendering) always gets higher priority than the one of NVIDIA for some reason. I could not get working OpenGL apps with NVIDIA hardware support with PRIME Render Offload. For some reason always the Mesa library gets selected. This might be somehow related to usrmerge change in Tumbleweed. I don't understand what's going on here. -- You are receiving this mail because: You are on the CC list for the bug.

I suggest to switch to suse-prime's nvidia mode (more power consuming of course) or your workaround for teams/skypeforlinux.

__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=mesa <teams|skypeforlinux>

OK, with `prime-select nvidia` (and logging in again), the situation is as follows:

glxinfo | grep vendor and __GLX_VENDOR_LIBRARY_NAME= glxinfo | grep vendor BOTH report server glx vendor string: NVIDIA Corporation client glx vendor string: NVIDIA Corporation OpenGL vendor string: NVIDIA Corporation

and consequently both

/usr/bin/teams and __GLX_VENDOR_LIBRARY_NAME= /usr/bin/teams DO NOT work!

However

__GLX_VENDOR_LIBRARY_NAME=mesa glxinfo | grep vendor server glx vendor string: NVIDIA Corporation client glx vendor string: Mesa Project and SGI OpenGL vendor string: Mesa/X.org

So, NVIDIA GLX server but Mesa client lib And then

__GLX_VENDOR_LIBRARY_NAME=mesa /usr/bin/teams in fact works.

But `prime-select nvidia` by itself does not fix the problem. Looks like a problem with NVIDIA client GL libs. -- You are receiving this mail because: You are on the CC list for the bug.

Things are working for me with "prime-select nvidia". glxinfo, glxgears, teams and skypeforlinux. Tested on icewm and GNOME/X.Org.

I see the issue only with "prime-select intel" when enabling PRIME Render Offload mode with the appropriate environment variables

__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia

Oh, that's interesting and led me to find a file

cat /etc/profile.d/nvidia-offload.sh export __NV_PRIME_RENDER_OFFLOAD=1 export __GLX_VENDOR_LIBRARY_NAME=nvidia

which I didn't remember, I had created. I have disabled that file now and indeed, `prime-select nvidia` fixes teams for me too, now. However, I still can trigger the problem when I run

__NV_PRIME_RENDER_OFFLOAD=1 /usr/bin/teams

I guess, with `prime-select nvidia`, offloading should just be a no-op and not break anything. -- You are receiving this mail because: You are on the CC list for the bug.
