Nexuiz crashing on debian sid , radeon OSS Driver

[noone]

I found out, the default setting for deluxemapping is ON, also when resetting to defaults. That will make nexuiz crash on my system.

I have x86_64 Linux system with ATI propiertary fglrx driver v 8.29.6

Having
r_glsl_deluxemapping "0"
in .nexuiz/data/config.cfg
makes it better. (And also disabling Bloom makes fps tolerable.)

Fedora still provides only v 2.2.1 of Nexuiz. Is there some big bug fixes in v2.2.2 so one should try to recompile from sources? Some servers say they are running v 2.2.2

Interesting, i see no reason why gl_deluxemapping should crash Nexuiz. It just makes it do bumpmapping on the whole map from the info in the light map and not just from the realtime lights.
Maybe the free ati drivers have problems with large shader programs.. No idea how to test this though.

noone was using fglrx, not the free r300 drivers. And fglrx is known to crash while compiling opengl shaders on some systems...
div0 bought a cheap radeon 9600 to investigate this months ago, but afaik he wasn't able to reproduce the crash.

[esteel]

Yeah 'free ati drivers' = r300
Hehe ati free or non free seems to be rather bad

Well I tried again, and yes it seems only be this deluxemapping ON/OFF which makes it "crash" or not.

This happens, if I hit the 'reset' button in the Effects options:

I also run 3Dmark06, if it tells something. X700 does not support SM 3.0
http://service.futuremark.com/orb/resul ... ID=7415103

Aftert the crash, if I only disable the deluxemapping and connect to the same server, it does not crash anymore.

[esteel]

Yes it indeed seems to be a problem with the r300 driver, it crashes when it does (re)compile the shader. Best thing for now is to disable the deluxemapping and file a bug report to the r300 developers..

[SavageX]

I filed a bug report for the r300 driver - but completely messed it up by copying in that last trace (that's from ATI's drivers, not from the DRI one!).

https://bugs.freedesktop.org/show_bug.cgi?id=9571


D'oh, I feel like an idiot. That bug report is spammed with wrong information. It's not DRI r300 having a GLSL problem (that one seems to have different problem), it's fglrx having a GLSL problem.

[SavageX]

Oh, and a question from a DRI developer:

<MrCooper> which version of libgl1-mesa-dri does he have? 6.5.1-0.5 ensures building with -fno-strict-aliasing, the lack of which could cause all sorts of weird crashes


edit: Oh, and can you please provide a gdb trace with DRI running?

[noone]

Just a notice, the newest ATI fglrx driver v 8.33.6 still has the same bug:

I would try with open source r300 driver also, but somehow noone has compiled it for FC5. Switching to FC6 soon, then I will.
I guess the original reporter is not reading this thread anymore as (s)he didn't ever supply a gdb bt-dump about the crash.

Just a notice, the newest ATI fglrx driver v 8.33.6 still has the same bug:

Did you file a bug report at ati/amd yet? I'm not sure if Nexuiz is big enough to make them consider a bugfix with its at least a start.. i guess other games would also have problems then.. And their driver is the right place for a bugfix instead of some ugly workaround in the engine (which LordHavoc does not like btw)
