I've just installed antergos with gnome de and bumblebee on asus R542 laptop.

When I run primusrun glxspheres64 it fails and logs this:

$ primusrun glxspheres64
Polygons in scene: 62464 (61 spheres * 1024 polys/spheres)
Visual ID of window: 0x130
Context is Direct
OpenGL Renderer: GeForce 930MX/PCIe/SSE2
Segmentation fault (core dumped)

optirun glxspheres64 is ok:

$ optirun -c yuv glxspheres64
Polygons in scene: 62464 (61 spheres * 1024 polys/spheres)
Visual ID of window: 0x21

  • Usually when there's a segfault one should collect a backtrace in a debugger, which may help the developers track down the issue. – thrig Jul 9 '18 at 14:24
  • @thrig so what should I do? – Milad Abbasi Jul 9 '18 at 14:51
  • You mention you "checked out other forums" -- which ones, and what advice have you tried so far? Arch (on which Antergos is based) has an open bug about this: bugs.archlinux.org/task/58933 – JigglyNaga Jul 9 '18 at 16:38

I had the same problem here. Just downgrade mesa to 18.0.4. I use Arch, so I did: pacman -U /var/cache/pacman/pkg/mesa-18.0.4-1-x86_64.pkg.tar.xz

Not sure if the problem is in mesa, xserver or primus, but here's the upstream bug report: https://bugs.freedesktop.org/show_bug.cgi?id=106910 and here's a simple workaround:

export LIBGL_DRI3_DISABLE=1
primusrun glxgears
