Problem with EVE tutorial triangleset.C

Hi everyone,

I’m running ROOT 5.34/32 on a Fedora 23 system, and I’ve been having some trouble with the EVE package. As a minimal working example, when I run the triangleset.C tutorial macro (see https://root.cern.ch/root/html/tutorials/eve/triangleset.C.html), ROOT immediately segfaults, producing the following output:

[code]root [0] .x triangleset.C
root [1]
*** Break *** segmentation violation

There was a crash.

I’m using the official Fedora 23 ROOT and mesa-libGL packages. I’ve also tried setting the environment variable “LIBGL_ALWAYS_INDIRECT=1” before running the macro. WIth that change, root gives me the following error message and hangs.

Has anyone else seen this before? Some of the other tutorials seem to work ok, but the event viewer seems to be pretty fragile on my system.

Not sure if it helps …

Thanks, Pepe. Those posts gave me a couple more things to try, but still no luck. I tried running glxgears, and it works ok unless I set LIBGL_ALWAYS_INDIRECT=1. It then fails to run.

Running glxinfo gives the following output:

Strangely enough, alice_esd.C works fine, even though it’s significantly more complicated.

Hi,

Yeah, I know about this … newer intel drivers don’t allow one to use vertex arrays within display lists. I started working around this but got swamped with other things so I still need to finish it and put it in the repo. The idea was that you’d set a flag in your rootrc and eve/gl would disable display lists for objects that use vertex arrays. There really aren’t all that many (triangleset and pointset and derivatives, which include line and track).

If you build root yourself, look for fUseDL = kTRUE/FALSE in the GL renderer class that’s giving you trouble, in triangleset.C case it’s TEveTriangleSetGL:
github.com/root-mirror/root/blo … GL.cxx#L32
and set it so that display lists are not used.

Cheers,
\m

Thanks for your help! For reference, I’ve discovered another workaround that is possible on machines (including mine) that have an Nvidia Optimus setup (low-performance integrated graphics card [typically made by Intel] and a high performance Nvidia one). Invoking ROOT or any root-based standalone executable using the optirun tool (“optirun root” in a terminal) bypasses the Intel card and uses Nvidia for all OpenGL rendering, solving this issue.
