Problem with EVE tutorial triangleset.C

[sjg]

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.

SL 6.X / SLC 6.X / CentOS 6.X / RHEL 6.X

I encountered a strange problem that causes OpenGL (GLX) applications to fail on SL6X, SLC6X, CentOS6X and RHEL6X (where X = 3 for the time being). Applications die with errors in form (I login to a remote machine, running one of these systems, using “ssh -X -Y”): […]$ glxinfo name of display: localhost:11.0 Error: couldn’t find RGB GLX visual or fbconfig […]$ glxgears Error: couldn’t get an RGB, Double-buffered visual […]$ root (…) Error in TGLWidget::CreateWindow: No good OpenGL visua…

TEve seems to crash my computer

Hello all, I’m having some strange issues with TEve. When I try to run alice_esd.C under $ROOTSYS/tutorials/eve, my computer closes all programs and logs me off. Due to this, I don’t have an error message available to show. We tried sending the output to a .txt file using >>, but we still couldn’t obtain an error message. I’m currently using Scientific Linux 6.6 and ROOT 5.34 on an hp Pavilion. Thank you in advance for any help you can provide with this issue!

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.
