Crash on geom tutorial on ARM ROOT

ROOT
1

Hello,

I’m smoke-testing a fresh build (from CVS trunk) of ROOT on an ARM-based laptop. I tried running the geom tutorial geomAlice_itsv.C and get the following (a crash):

Error in <RootX11ErrorHandler>: BadMatch (invalid parameter attributes) (TGVerticalFrame XID: 37748992, XREQ: 1)
TGVerticalFrame:	37748992
	TGCompositeFrame:	37748953
	TGLSAFrame:	37748942

I’m at a loss. Does this look familiar to anyone?

Thanks,
Matthew Lockner

Hi Matthew,

This means there’s a problem in communication with the X server, maybe due to unsupported protocol extensions (like glx).

Does glxgears work? What’s the output of glxinfo?

What distro do you run there?

Cheers,
Matevz

Hello Matevz,

glxgears works (reports ~65 FPS or so). I am attaching the output of glxinfo below as glxinfo.txt.

This is AI OS, which I understand is an Angstrom Linux derivative.

Hi,

This all seems ok. Can you try updating to the latest mesa … or downgrading to an older one?

Maybe, before doing that, try switching off DRI in the xorg.conf.

Sorry, but such problems are really hard to trace down.

I’ll try googling some more …

Good luck,
Matevz

Is it possible to install ATI fglrx drivers on this thing?

Possibly, but I do not believe it is ATI hardware (it is an “SGX” from what I’ve read, and I’m not familiar with that name).

I’ll try your suggestions above and get back on it (but I may wait until after final exams). It also comes with stock Ubuntu, and that may prove more cooperative.

Thanks,

Specifically, it has a “PowerVR SGX530” GPU.

Hi,

I deduced it’s ATI based on:
OpenGL renderer string: Mesa DRI R200 (RV280 5960) 20090101 AGP 8x x86/MMX+/3DNow!+/SSE TCL
this line in glxinfo dump.

Good luck and may the Google be with you :slight_smile:

Let me know how it goes,
Matevz
