[Bug] signal 11 on startup on Ubuntu 12.04 32bit with NVidia card

[johpe]

I just downloaded paintball2_build035_linux_full.tar.gz and tried to run it.
What I get is:

Code: [Select]

Paintball 2 -- Version 2.0
Execing configs/default.cfg.

I am running 32 bit Xubuntu (Ubuntu wuth the XFCE window manager) version 12.04 with 4 GB RAM.

lspci shows:

Code: [Select]

01:00.0 VGA compatible controller: NVIDIA Corporation GT216 [GeForce GT 220] (rev a2)
for my graphics card.
I have connected two monitors (first attached to the digital connector with 1680x1050, second attached to analog with 1280x1024) to my card which both show a single X screen at 2960x1050 pixels.

Are there any parameters or settings I could change to get more debug info or to make this work?

[johpe]

I also tried this on my laptop, also Ubuntu 12.04 with xfce but with an ATI Radeon mobile card and got the same segmentation fault.

I have xubuntu 12.04 (64bit) running this game ok I have had it working on a geforce 8500 and a 450 gtx

I suggest

1) checking you have all dependencys installed - also re-download it (just in case you have a corrupted archive (unlikely)
2) disabling twinview and see if the problem persists. (it is possible to specify which screen to start an app I believe)
3) chaning sound output to SDL (if you want sound)

For extra debugging:-

- Install gdb
- launch game with

gdb ./paintball2
- type run

[johpe]

Thank you for your suggestions!
I checked all dependencies and I think they are all met (the list does not give specific version which may be required, but I do have just the standar version for Ubuntu 12.04).
I also tried a number of different screen configurations, including disabling the second screen completely. (my normal configuration uses Xinerama, but I also tried separate X screens without Xinerama and Twinview).
I also changed the sound driver to SDL.
Nothing helped, I am still getting the segmentation fault.

When running with gdb I get:

Code: [Select]

Program received signal SIGSEGV, Segmentation fault.

Looks like your libGL is broken somehow. Does your CPU supports SSSE3? List here: https://en.wikipedia.org/wiki/SSSE3

[johpe]

This is the output of "cat /proc/cpuinfo
As you can see it shows ssse3 in the flags section so I would think this is supported.

About libgl: which package in ubuntu would that be? It is hard to believe that libgl is broken as all other 3D programs work without a problem.

[jitspoe]

Sounds like maybe some kind of dependency is missing for the driver.  I'm not sure how/why that would happen.  I'm guessing it's using the memcopy when it's loading the fragment program for the water effect.  You might try renaming pball/scripts/water1.arbf and see if that stops the crash.

[johpe]

I renamed water1.arbf to water1.arbf.bak but the crash still occurs.

[johpe]

Is this known to run on Ubuntu 12.04 at all?
I did a systematic test on the following computers, all with Ubuntu 12.04 (32 bit Intel) installed, and none worked, all give a segmentation fault:

1) my desktop, with a NVidia GT216 (GeForce GT 220) rev a2 video adapter, running in various configuration (TwinView, Xinerama and single screen mode)
2) my Lenovo T500 Laptop in two different BIOS settings:
- on chip Intel graphics enabled
- AMD ATI RV635 [Mobility Radeon HD 3650] chip enabled

This is really a pity because some time ago, our family enjoyed playing Paintball on exactly the same computers (but with earlier versions of both Ubuntu and paintball)

[jitspoe]

You could try launching paintball2 with the command line "+set r_reflectivewater 0".  I think it may still run the init and crash, though.

[klann24]

umm, can someone help me??

[deadfroggy]

umm, can someone help me??

create a post in the 'Help and support' section. Don't forget to add everthing you know about it or whatever.

[klann24]

ok thanks

[johpe]

Yes, it still crashes when I start it with these parameters on the command line
I guess I am out of luck here ... I'd still be curious if it is just something about my particular hw/sf or if there are others with Ubunto 12.04 who experience similar problems.

[jitspoe]

Try adding this to the command line: "+set gl_arb_fragment_program 0"

[johpe]

Try adding this to the command line: "+set gl_arb_fragment_program 0"

Great!- thanks! This did it -- with this parameter present, the program starts and seems to work just fine!!
What does that parameter do?

[jitspoe]

That parameter disables ARB fragment programs completely, so you won't get things like the fancy water effects.  I'm really not sure why this is crashing.  Looks like it might be a bug in the drivers.  I'm curious if you could find another 32bit OpenGL application that uses ARB fragment programs and see if it crashes or not.

I am afraid I do not know enough about this topic to find out for myself which application could be used or how to create a minimal testcase. But if you have some code or a link to an app I should try I will provide the results if that helps with debugging the problem.
